The major objectives of the present unit are as follows:
 To understand the complexity of the interaction of economy and
environment;
 To understand the arguments of Limits to Growth;
 To learn about the emergence of the idea of sustainable development.
1.1 INTRODUCTION
Economics growth and environment are so deeply connected to each other
that goal of sustainable development tends to be incomplete if
environment friendly approach of growth is not followed. The objective of
this unit is to impart the knowledge about the importance of environments
to the economy and to understand the relationship between environment
and development. The rapid economic growth over the last decades
coupled with population growth has put huge pressure on environ ment. As
a result, there has been significant degradation of the environment
throughout the world. Hence, the need for promoting sustainable
development has assumed greater importance. The present unit discusses
link between economic growth and environment , how economic activity
depends upon and affects the natural environment. It considers the
argument that the environment sets limits to economic growth and learn
about the emergence of the idea of sustainable development.

2 1.2 ECONOMIC GROWTH AND ENVIRONME NT
The present unit is classified into following segments:
Environment and economy are closely interlinked. Environment provides
raw materials and other resources to the economy. The economy
transforms those raw materials derived from the nature into consu mable
goods. However, along with production of goods, the producers also
generate wastes and pollutants which are ultimately disposed into the
environment. The environment also acts as a sink of wastes pollutants. But
it has a limited capacity of waste ass imilation as there are some wastes or
pollutants which cannot be degraded easily and that tends to affect
economic growth in future.
Economic growth and Environment both are connected to each other and
therefore influence each other. Natural resources are vital for securing
economic growth and development, not only for present but for future
generations too.
The environment plays an important role in supporting economic activity.
It contributes:
 Directly, by providing resources and raw materials such as wat er,
timber and minerals that are required as inputs for the production of
goods and services;
 Indirectly, through services provided by ecosystems including carbon
sequestration, water purification, managing flood risks, and nutrient
cycling.
But economic growth has pressurized the environment at national and
international level over the time. The relationship between ecology and the
economy has become significant as humans gradually understand the
impact of economic decisions are quite visible on the susta inability and
quality of the planet.
The World Bank estimated that, under present productivity trends and
given projected population, the output of developing countries would be
about five times higher by the year 2030 than it is today. The output of
indus trial countries would rise more slowly, but it would still triple over
the same period. If environmental pollution were to rise at the same pace,
environmental adversities would occur. Millions of people would become
sick or die from environmental causes, and the planet would be
significantly and irreparably harmed.
The conflict between economic growth and the environment is a complex
issue and sharper today than ever before. Indeed, the relationship between
economic growth and the sustainability of ecosyst ems has been
extensively discussed in the literature, but the results remain controversial.
While economic growth has produced many benefits – raising standards of
living and improving quality of life across the world – it has also resulted munotes.in

3 in the depletio n of natural resources and the degradation of ecosystems.
There has been much debate over whether or not it is possible to achieve
economic growth without unsustainably degrading the environment, and a
growing realisation that economic growth at the curren t rate of depletion
and degradation of environmental assets cannot continue indefinitely.
Environment supports Economic growth:
Natural environment affects economic activities in number of ways. The
OECD defines natural capital as “natural assets in their role of providing
natural resource inputs and environmental services for economic
production”. This ranges from clean air and water, to the soils we use to
grow crops and the minerals and ores we extract from the earth.
Natural capital contributes to econo mic output through two main channels:
 Directly as an input to the process of economic activity; and
 Indirectly through its effect on the productivity of the other factors of
production.
 Natural capital as a direct input to wealth creation:
The natural envi ronment provides the raw materials and resources for
economic production of goods and services. These resources are classified
into Non -renewable and renewable resources.
Non-renewable resources are those with a finite endowment, which can
be depleted over time. Non -renewable resources like fossil fuels, minerals,
metals, and basic aggregates are extracted from the natural environment to
produce energy, machinery, consumer products, the built environment,
and much else; in 2007, UK economic activity resulte d in the extraction of
over 450 million tonnes of fossil fuels and minerals within the UK.
Renewable resources are those which are capable of being replenished
through natural processes or their own reproduction. However, these
resources can be exhausted i f they are consumed at a rate faster than the
rate of replenishment. Renewable resource, such as forests and fisheries,
contribute directly to economic activity and Country’s GDP.
 Natural capital as an indirect input to wealth creation:
Apart from direct e ffects of environment, indirect inputs from the
environment also affect the economic processes to a great extent. The
indirect inputs provided by ecosystems facilitate the processes of
production and act as a sink for the adverse environmental effects of
economic activity. They include:
Global life support functions – Natural areas provide global life support
functions, including climate regulation and regulation of the chemical
composition of the atmosphere and oceans. While natural areas play a role
in the maintenance of life -essential services, it is difficult to evaluate and
demonstrate the contribution that particular habitat types or areas make. munotes.in

Page 4

Environmental Economics
4 However, one area where the contribution of particular habitats is being
recognised and evaluated more ex plicitly is with regard to the ability of
forests to act as a store for carbon.
Water regulation – Natural areas can buffer hydrological flows and
dampen environmental fluctuations, provide flood and storm protection,
and prevent run -off damage. Natural pr ocesses can also provide water
quality benefits; for example, by preventing sediment run -off into rivers.
Pollution filtering – Natural resources play an important role in pollution
control and detoxification, including the removal of nutrients and
polluta nts from water, filtering of dust from the air, and providing noise
reduction.
Waste sink – This is the capacity of the environment to assimilate the
waste products of production and consumption and convert them into
harmless or ecologically useful products . The physical capacity of the
land, water and the atmosphere to absorb wastes is determined by physical
factors such as the climate, rainfall, wind patterns, and geographical
location. The natural environment provides a repository for all non -
recycled was te produced by economic activity. In the absorptive capacity
of the atmosphere, the oceans, and the soil, the natural environment is able
to assimilate some of that waste without diminishing the provision of its
other services.
Soil retention and provision – The natural environment, such as many
wetland habitats, provide benefits by preventing soil loss and by storing
silt.
Nutrient cycling – Ecological processes provide benefits through the
storage, processing, and acquisition of nutrients essential for pl ant growth.
Waste decomposition – Naturally occurring micro -organisms provide
benefits through their ability to break down organic matter and speed up
the process of waste decomposition.
Economic growth impacts environment:
Economic activities and economic growth have grater impact on
environment across the world. Society has become very much aware of the
environmental impact of agriculture/industry over the last few decades
because of increasing negative consequences of certain economic
practices. Examples of the negative consequences of agriculture include
water pollution (both surface and groundwater), soil erosion and soil
compaction, the loss of wetlands because of drainage, and the loss of
biodiversity because of land clearance for more agriculture as well as the
adoption of new technologies. Air pollution, water pollution, noise
pollution are negative consequences of industrial growth which cannot be
overlooked.
At the same time the demand for a clean and healthy natural environment
provides opportunit ies for employment and wealth creation; for example, munotes.in

Page 5

Growth and Environment

5 organic agriculture and industries responsible for managing and protecting
natural resources. Other industries aim to reduce the environmental
impacts of economic activity; for example, through generatin g renewable
energy, through waste management techniques, and through products and
technologies that reduce air and noise pollution from production
processes. Yet others aim to mitigate adverse environmental impacts and
restore natural assets to their previ ous condition, such as water treatment
services and land remediation.
Thus, the link between the economy and the environment are manifold:
the environment provides resources to the economy, and acts as a sink for
emissions and waste. Natural resources are essential inputs for production
in many sectors, while production and consumption also lead to pollution
and other pressures on the environment. Poor environmental quality in
turn affects economic growth and wellbeing by lowering the quantity and
quality o f resources or due to health impacts, etc. In this context,
environmental policies can curb the negative feedbacks from the economy
on the environment (and vice -versa). But how effective they are and
whether they generate a net benefit or a net cost to soc iety is the subject of
much debate and depends on the way they are designed and implemented.
1.3 ENVIRONMENT AS AN ECONOMIC AND SOCIAL
GOOD/ASSET:
Environment is considered as Economic and social good as it plays an
important role in economic growth and s ocial well -being of a nation. The
natural environment plays a key role in our economy, as a direct input into
production and through the many services it provides. Environmental
resources such as minerals and fossil fuels directly facilitate the
production of goods and services. The environment provides other
services that enable economic activity, such as sequestering carbon,
filtering air and water pollution, protecting against flood risk, and soil
formation. It is also vital for our wellbeing, providing us with recreational
opportunities, improving our health, and much more.
Environmental resources, it may be materials, services or information all
are valuable for society and economy. Food from plants and animals,
wood for cooking, heating, and building, metals, coal, and oil are all
environmental resources. Clean land, air, and water are environmental
resources, as are the abilities of land, air, and water to absorb society's
waste products. Heat from thesun, transportation and recreation in lakes,
rivers , and oceans, a beautiful view, or the discovery of a new species are
all environmental resources. The environment provides a vast array of
materials and services that people use to live. Often these resources have
competing uses and values. A piece of lan d, for instance, could be used as
a farm, a park, a parking lot, or a housing development. It could be mined
or used as a garbage dump. Some resources are renewable, or infinite, and
some are non -renewable, or finite. Renewable resources like energy from
the sun are plentiful and will be available for a long time. Finite resources,
like oil and coal, are non -renewable because once they are extracted from munotes.in

6 the earth and burned, they cannot be used again. These resources are in
limited supply and need to be us ed carefully. Many resources are
becoming more and more limited, especially as population and industrial
growth place increasing pressure on the environment.
1.4 LIMITS TO GROWTH
There are several theories describing the relationship between economic
grow th and environmental quality. The Limits to growth theory are one of
them. The limits to growth theory consider the possibility of breaching
environmental thresholds before the economy reaches the EKC
(Environmental Kuznets Curve) turning point.
The limits theory defines the economy -environment relationship in terms
of environmental damage hitting a threshold beyond which production is
so badly affected that the economy shrinks.
An important event in the emergence in the last decades of the perception
that there is a sustainability problem and it was published in 1972 in a
book, ‘The Limits to Growth’ (Meadows et al., 1972), which was widely
understood to claim that environmental limits would cause the collapse of
the world economic system in the middle of the twenty -first century.
The book was condemned by most economists, but influenced many other
people.
The Limits to Growth reported the results of a study in which a computer
model of the world system, World3, was used to simulate its future.
World3 repre sented the world economy as a single economy, and included
interconnections between that economy and its environment.
According to its creators, “World3 was built to investigate five major
trends of global concern – accelerating industrialization, rapid po pulation
growth, widespread malnutrition, depletion of non -renewable resources,
and a deteriorating environment. These trends are all interconnected in
many ways, and their development is measured in decades or centuries,
rather than in months or years. Wi th the model we are seeking to
understand the causes of these trends, their interrelationships, and their
implications as much as one hundred years in the future.”
It incorporated:
(a) a limit to the amount of land available for agriculture;
(b) a limit to the amount of agricultural output producible per unit of
land in use;
(c) a limit to the amounts of non -renewable resources available for
extraction;
(d) a limit to the ability of the environment to assimilate wastes arising
in production and consumption, which limit falls as the level of
pollution increases. munotes.in

Page 7

Growth and Environment

7 On the basis of a number of simulations usingWorld3, the conclusions
reached by the modelling team were as follows:
1. If the present growth trends in world population, industrialization,
pollution, f ood production and resource depletion continue
unchanged, the limits to growth on this planet will be reached
sometime within the next 100 years. The most probable result will
be a sudden and uncontrollable decline in both population and
industrial capacit y.
2. It is possible to alter these trends and to establish a condition of
ecological and economic stability that is sustainable far into the
future. The state of global equilibrium could be designed so that the
basic material needs of each person on earth are satisfied and each
person has an equal opportunity to realize his or her individual
human potential.
3. If the world’s people decide to strive for this second outcome rather
than the first, the sooner they begin working to attain it, the greater
will be their chances of success.
What The Limits to Growth actually said was widely misrepresented.
It was widely reported that it was an unconditional forecast of disaster
sometime in the next century, consequent upon the world running out
of non -renewable re sources. It was widely reported that the World3
results said that there were limits to ‘economic growth’. In fact, what
they said, as the conclusions quoted above indicate, is that there were
limits to the growth of material throughout for the world econom ic
system.
A sequel (Meadows et al., 1992) to The Limits to Growth, written by
the same team and entitled ‘Beyond the Limits’, was published in 1992
to coincide with the UNCED conference held in Rio de Janeiro. The
publication of the sequel generated much less controversy than the
original did.
As far as implication of limit theory is concerned, the available global
data and scenario of past 30 years, indicate that the three conclusions
drew in The Limits to Growth are still valid and need proper attention
towards it.
1.5 SUSTAINABLE DEVELOPMENT
The question arises, will the world be able to sustain economic growth
indefinitely without controlling the environment degradation? Are there
trade -offs between the goals of achieving high and sustainable rates of
economic growth and attaining high standards of environmental quality?
Increased extraction of natural resources, accumulation of waste and
concentration of pollutants will therefore overwhelm the carrying capacity
of the biosphere and result in the munotes.in

Page 8

Environmental Economics
8 degrada tion of environmental quality and a decline in human welfare.,
despite rising incomes. Furthermore, it is argued that degradation of the
resource base will eventually put economic activity itself at risk. To save
the environment and even economic activity from itself, economic growth
must cease and the world must make a transition to a steady -state
economy.
Sustainable Development focuses on meeting the needs of the present
without compromising the ability of future generations to meet their
needs. The conc ept of sustainability is composed of three pillars:
Economic, Environmental, and Social —also known informally as
Profits, Planet, and People . Sustainability encourages businesses to
frame decisions in terms of environmental, social, and human impact
for th e long -term, rather than on short -term gains such as next quarter's
earnings report. It influences them to consider more factors than
simply the immediate profit or loss involved. Increasingly, companies
have issued sustainability goals such as commitment to zero -waste
packaging by a certain year, or to reduce overall emissions by a certain
percentage. These companies can achieve their sustainable needs by
cutting emissions, lowering their energy usage, sourcing products from
fair-trade organizations, and e nsuring their physical waste is disposed
of properly and with as small of a carbon footprint as possible. The
push for sustainability is evident in areas such as energy generation
where the focus has been on finding new deposits to outpace the
drawdown on existing reserves. Some electricity companies, for
example, now publicly state goals for energy generation from
sustainable sources such as wind, hydropower, and solar.
The 2005 World Summit on Social Development identified sustainable
development goals, s uch as economic development, social
development, and environmental protection . This view has been
expressed as an illustration using three overlapping ellipses indicating
that the three pillars of sustainability are not mutually exclusive and
can be mutual ly reinforcing. In fact, the three pillars are
interdependent, and in the long run, none can exist without the others.
The three pillars have served as a common ground for numerous
sustainability standards and certification systems in recent years, in
particular in the food industry. Some sustainability experts and
practitioners have illustrated four pillars of sustainability or a
quadruple bottom -line. One such pillar is future generations, which
emphasizes the long -term thinking associated with sustainabi lity.
There is alsoan opinion that considers resource use and financial
sustainability as two additional pillars of sustainability. Sustainable
development consists of balancing local and global efforts to meet
basic human needs without destroying or degra ding the natural
environment. The question then become show to represent the
relationship between those needs and the environment A study from
2005 pointed out that environmental justice is as important as
sustainable development. Ecological economist Herm an Daly asked,
"what use is a sawmill without a forest?" From this perspective, the
economy is a subsystem of human society, which is itself a subsystem munotes.in

9 of the biosphere, and an obtain in one sector is a loss from another.
This perspective led to the neste d circles' figure of 'economics' inside
'society’ inside the 'environment' .

Figure 1.1 Sustainability
Some ecologists argue economic growth invariably leads to environmental
damage. However, there are economists who argue that economic growth
can be cons istent with a stable environment and even improvement in the
environmental impact. This will involve a shift from non -renewables to
renewables resources. A recent report suggests that renewable energy is
becoming cheaper than more damaging forms of energy production.
Environmental policy which protects the environment, through
regulations, government ownership and limits on external costs can enable
economic growth to be based on protection of the environmental resource.
It is possible to replace cars runni ng on petrol with cars running on
electricity from renewable sources. This enables not only an increase in
output, but also a reduction in the environmental impact. There are
numerous possible technological developments which can enable greater
efficiency, lower costs and less environmental damage.
Include quality of life and environmental indicators in economic statistics.
Rather than targeting GDP, environmental economists argue we should
target a wider range of living standards + environmental indicators . The
following chart depict sustainable Economic development can be achieved
without environmental damage.

1.6 SUMMARY
Thus, this unit is devoted to the vital relation between economic growth
and environment. It studies the impact of environment on growth and at
the same time impact of growth on environment. The role of environment
in economic growth and development is quite obvious because
environment acts as a social good or asset. Lim its to growth theory is an
eye opener for present and future generation. If environment is not
protected then it can limit the growth and collapse the economic system of
the world in near future. Sustainability can be achieved through proper
combination of three pillars: Economic, Social and Environment.
Sustainable economic development is possible without environmental
damage if proper policy is formed and implemented. The unit highlights
the limit to growth and sustainability in precise manner to make the
concepts understandable for our leaners.

The major objectives of the present unit are as follows:
 To understand the nexus between environment and development
through Kuznets Environment Curve;
 To learn abo ut different types of Natural resources useful for economic
growth and development;
 To understand the importance of Natural resource Management and
Green Accounting Methodology;
2.1 INTRODUCTION
The relationship between the environment degradation and eco nomic
development is observed as inverted U shape curve, known as
Environmental Kuznets Curve. The hypothesis populated that in the early
phase of development, environmental degradation increases. But as the
level of development reaches certain threshold t he people become aware
about the environment and invest more in environmental protection. This
leads to decline in environmental degradation.The unit deals with allmajor
areas of natural resource: exhaustible resources, renewable resources and
Common Prope rty resources. One of the most needed fields in
Environmental Economics, Natural Resource Management is also
highlighted in the present unit. Natural Resource Management refers to the
sustainable utilization of major natural resources Green accounting or
Environmental accounting is also analysed in this unit. Green NNP or
environmentally adjusted NNP is considered the best measure of
sustainable development. munotes.in

12 2.2 ENVIRONMENTAL KUZNETS CURVE
Present unit is classified into following segments:
The nexus betwe en environment and development is quite complex. The
question of how are they related to each other is similar to the theory
posed by Simon Kuznets in 1955, regarding the relation between level of
income and inequality along with economic development. Kuzn ets
hypothesized that there is an inverted U -shaped relationship between
inequality and economic development.
The environment and development trade -off can also be explained in
terms of Environment Kuznets curve.
Gene Grossman and Alan Krueger in their s tudies of the relationship
between the environment degradation and economic development found a
similar inverted U -shaped relationship. This inverted U -shaped
relationship between the environmental degradation and economic
development is known as Environme ntal Kuznets Curve (EKC). The EKC
hypothesis expresses the most likely relationship between the environment
and economic development. It states that the environmental degradation is
low when the level of economic development is low. The environmental
degra dation increases with economic development in the early phase but it
comes down at the later stage of development. That is, in the initial stage
of development, environmental degradation increases but eventually
declines at certain threshold level of incom e.

Figure 2.1 : The environmental Kuznets curve: A development -environment relationship
In the figure 2 .1 the environmental Kuznets curve is inverted U -shaped.
The level of environmental degradation is measured a long the vertical axis
and the level of GDP per capita (a measure of development) is measured munotes.in

Resources and Green
Accounting
13 along the horizontal axis. The curve shows that as the level of income
increases, the environmental degradation also increases but up to point.
Then turning point reached where level of environmental degradation
starts to decline as income increases.
The increase in environmental degradation in the initial phase can be
attributed to the heavy emphasis on economic growth and capital
formation to enhance production and consumption. It is due to heavy
emphasis on industrial development and movement of the economy from
the clean agrarian economy to polluting industrial economy. For the early
phase of development, people tend to neglect environmental matters due
to high level of poverty, lack of awareness, income inequality and lack of
community level institutions etc. These result in increase in environmental
degradation in the early phase of development.
The decline in environmental degradation after the certain thresh old level
of income is attributable to technological change and efficiency in use of
energy and other resources. The technical innovation enables the economy
to produce more level of output with the same resources. At the same
time, it encourages the recyc le of materials and reduces the pressure on the
environment. Further, the in stitutions of natural resource not linked to
environment, increase in education and awareness among the people about
the ill effects of environmental degradation and better impleme ntation of
environmental regulations contribute to reduce environmental degradation.
In fact the person with higher income has a tendencyto prefer better
environmental quality and spend more to consume the environment. The
economic structure also changes f rom polluting industrial to clean services
economy.
Criticisms
The EKC relationship between the environmental degradation and the
level of development has been criticized under the following grounds:
 The Environmental Kuznets curve has been found only for some air
quality indicators especially local pollutants. There is no evidence of
the EKC in case of global pollutant like carbon dioxide (CO2).
 The EKC hypothesis states that at certain threshold level of per capital
income the turning point will occur and increase in income beyond
that level heads decline in environmental degradation. However, it
does not say the exact level of income at which the turning will occur.
There is no agreement in literature on the income level at which the
environmental degrada tion starts declining.
 The shape of the curve may be N -shaped instead of invented U -Shaped
if the level of environmental degradation after declining for some time
again starts increasing as nations incomes continue to increase. Arrow
argues that the invert ed U -shaped relationship would appear to be
false, if pollution increases again at the end due to higher levels of
income and mass consumption.
 Suri and Chapman argued that reduction in pollution may not be
occurring. On a global scale because the wealthy nations have a munotes.in

Page 14

Environmental Economics
14 tendency of exporting the pollution intensive activities like,
manufacturing of clothing, furniture etc. to poorer countries. Thus, the
level of pollution may be declining in the developed countries but it is
compensated by the increase in p ollution in developing countries. So,
the pollution level at the global scale may remain unchanged with
economic development.
Thus, it can be concluded that the relationship between the environment
and economic development is quite complex and unpredictabl e. The
environmental Kuznets curve has tried to explain the possible relationship
between the level of environmental degradation and economic
development. The hypothesis populated that in the early phase of
development, environmental degradation increases. But as the level of
development reaches certain threshold the people become aware about
theenvironment and invest more in environmental protection. This leads to
decline in environmental degradation.
2.3 NATURAL RESOURCES: EXHAUSTIBLE,
RENEWABLE, COMMON P ROPERTY
RESOURCES
The various types of natural resources are used in human life for
maximum welfare. There are two types of resources used for the
development of a country. These types are of renewable and exhaustible or
non-renewable resources which are m ost important to any country's
sustainable development.
2.3.1 What Are Exhaustible Resources?
Exhaustible resources are also known as Non -renewable resource. Such
resources are natural substances which are not replenished with the speed
at which they are c onsumed. It is a finite resource. Fossil fuels such as oil,
natural gas, and coal are examples of Exhaustible resources. Humans
constantly draw on the reserves of these substances while the formation of
new supplies takes ages.
Exhaustible resources come f rom the Earth. Humans extract them in gas,
liquid, or solid form and then convert them for their use, mainly related to
energy. The reserves of these substances took billions of years to form,
and it will take billions of years to replace the supplies used .
There are four major types of Exhaustible resources: Oil, Natural gas,
Coal, and Nuclear energy. Oil, natural gas, and coal are collectively called
fossil fuels. Fossil fuels were formed within the Earth from dead plants
and animals over millions of year s—hence the name “fossil” fuels. They
are found in underground layers of rock and sediment. Pressure and heat
worked together to transform the plant and animal remains into crude oil
(also known as petroleum), coal, and natural gas.
All of these Exhausti ble or Non -renewable resources have proved
historically to be valuable energy sources that are inexpensive to extract. munotes.in

Page 15

Environmental Curve, Natural
Resources and Green
Accounting
15 Storage, conversion, and shipping are easy and cheap. Fuels created from
non renewable resources are still the primary source of all the power
generated in the world due to their affordability and high energy content.
Other Types of Exhaustible or Non -renewable Resources
Most nonrenewable resources are formed from organic carbon material
which is heated and compressed over time, changing th eir form into crude
oil or natural gas. However, the term non renewable resource also refers to
minerals and metals from the earth, such as gold, silver, and iron. These
are similarly formed by a long -term geological process. They are often
costly to mine, as they are usually deep within the Earth's crust. But they
are much more abundant than fossil fuels. Some types of groundwater are
considered nonrenewable resources if the aquifer is unable to be
replenished at the same rate at which it's drained.
The p roblem of pollution and environmental degradation arise due the
maximum and continuous use of exhaustible or Non -renewable resources.
2.3.2 Understanding Renewable Resources
A renewable resource is one that can be used repeatedly and does not run
out becau se it is naturally replaced. Examples of renewable resources
include solar, wind, hydro, geothermal, and biomass energy. Their supply
replenishes naturally or can be sustained. The sunlight used in solar energy
and the wind used to power wind turbines repl enish themselves. Timber
reserves can be sustained through replanting.
Renewable resource is important for sustainable development and
environment protection of a nation. There are main two types of renewable
resources i.e. biotic and abiotic. Animals, fis h, plants are the biotic
renewable resources whereas air, water, wind energy and solar energy are
the examples of abioticrenewable resources. These two types of renewable
resources stock don’t diminish completely. But it is highly impossible to
introduce e xclusion principle for renewable resources. Now -a-days we are
using all these renewable natural resource son large scale. So, in future we
may face the problem of sustainable development and environment
protection. Biofuel is popular renewable source nowad ays.
Biofuel, or energy made from renewable organic products, has gained
prevalence in recent years as an alternative energy source to exhaustible
resources such as coal, oil, and natural gas. Although prices are still higher
for biofuel, some experts proj ect that, due to increasing scarcity and the
forces of supply and demand, the prices of fossil fuels will grow higher,
making the price of biofuel more competitive.Types of biofuel include
biodiesel, an alternative to oil, and green diesel, which is made f rom algae
and other plants. Other renewable resources include oxygen and solar
energy. Wind and water are also used to create renewable energy. For
example, windmills harness the wind's natural power and turn it into
energy.

16 2.3.3 Common Property Resource s (CPR)
Common property resource means a good or service shared by a well -
defined community. In other words, collectively consumed goods and
services Goods and services that are consumed simultaneously by a group
of consumers or by the community as a whole are called Common
property resource. For example, public roads provided by the state or
defence services provided by the state. It is not possible to exclude people
from consumption of this good or it may not be desirable to exclude
people from consumptio n of this this good. These collectively consumed
gods are often public goods and merit goods.
But it is not mandatory that they be public goods or merit goods.
Sometimes, private sector can also provide collectively consumed goods
or services. But private sector will provide these only when it is possible
to individually collect fees or price from the consumers of this good.
The community controls the use of such resource by individuals.
However, enforcement is weak due to difficulties in monitoring. For
example, water in a village pond, which is a common property resource, is
used by the villagers only. The village as a community decides upon the
manner and the purpose for which the pond water can be used, which
results in a set of norms, evolved over tim e, and largely unwritten. In case
of a breach of the norms, however, imposition of penalty is poorly
enforced due to poor monitoring, subjectivity in the norms and
ambiguities in property rights. The common property regime for managing
natural resources is frequently misunderstood. It is often observed as a
situation in which there is no management regime in place; as a situation
of open access, which is free for all. Accordingly, resource degradation in
the developing countries is incorrectly attributed to 'common property
systems', whereas it actually originates in the dissolution of local, level
institutional arrangements. Therefore, there is a need to properly
understand the common property resources and its management systems
as these have direct bearin g on the sustainable development of natural
resources.
We can list a large number of Common Property Resources, which can be
brought under the broad headings like land resources, forest resources,
water resources, and fishery resources. These resources are being
degraded overtime due to overuse or lack of proper management.

Here we discuss briefly about these common property resources.

Land Resources
Common property land resource refers to lands identified with a specific
type of property rights. The com mon lands covered in the National Sample
Survey (NSS) enquiry are panchayat lands, government revenue lands,
village common lands, village thrashing lands, unclassified forest lands,
woodlands and wastelands, river banks, and lands belonging to other
house holds used as commons.

Resources and Green

17 Forest Resources
Another category of land for which common property rights may exist is
land under forests. Unclassified forests, with very low productivity, are
always open to use by local communities: Accordingly, both protected and
unclassified forests are treated as forming a part of common property
forest resources. It is, therefore, the subset of total forest area minus
reserve forests to which common property rights are assumed to exist.

Water Resources
There are a variety o f resources of water, which are in the public domain,
and a significant part of these are included in the category of commons.
Examples are flows of rivers, tanks and natural lakes, groundwater,
wetland and mangrove areas, and such other water bodies. Man -made
water resources such as dams and canals, tube wells, other wells, and
supply of all types of potable water also fall in the category of CPRs
depending upon their property rights. Unfortunately, even after many
debates about property rights (such as tr aditional rights, community rights,
and basic need human rights), water has not yet been declared as CPR in
India, though references are made in the water policy document indirectly.
By and large, water resources in India are in common property regimes
only. Irrigation canals are managed jointly by the government and
communities. Traditionally, tanks, village ponds, and lakes - all of which
are treated as CPRs -are sources of water for drinking, livestock rearing,
washing, fishing and bathing, and several s anitary -related activities.

Problems with Common Property Resources

Open Access
Basically, it is a situation where there are no enforceable property rights
over the use of the resource. Here, a right of inclusion is granted to anyone
who wants to use the resource. Examples of open access resources are
fishing in the open sea, river, lake, or ponds, ill -managed village common
grazing lands, buffer areas of forests, groundwater, etc. Open access
results from the absence - or breakdown - of a management and authority
system whose very purpose was to introduce and enforce a set of norms of
behaviour among participants with respect to the natural resource.

Tragedy of Common
People have always a tendency to use (misuse) public property according
to their whims and fancies. As the public property is not owned by any
individual, no one can claim for an exclusive ownership. The net result
being misuse of public properties. Perhaps this is the main reason for
garbage appearing in the public road, discharging effluen ts into the river,
public parks being misused, public buildings being disfigured etc.

Prof. Garrett Hardin examined the reasons why public properties are either
being misutilised or over utilized by the people. The answer that he
identified has been publi shed in the article titled “The Tragedy of
commons” (1968). He had studied the character of herdsmen in England.
Hardin anxiously watched out the peculiar behavior of herdsmen that they munotes.in

Page 18

Environmental Economics
18 are always prepared to add additional cattle into the pasture land in
England. The logic prevailed that the farmer who grazed the most cattle
stood to benefit most from the commons. But the tragedy of this kind of
action is that the land was overgrazed and destroyed. This came to be
known as “ Tragedy of Commons” . Though th e tragedy of commons is an
observation based on the real experience example, it finds its applicability
in most of the situation in which the resources are owned by the public.
There is a tendency to over exploit public resources resulting in total
destruc tion or non -availability of further resources.

2.4 ACCOUNTING AND NATURAL RESOURCE
MANAGEMENT, GREEN ACCOUNTING
2.4.1 Natural Resource Management (NRM):
Natural Resource Management refers to the sustainable utilization of
major natural resources, such as land, water, air, minerals, forests,
fisheries, and wild flora and fauna. Together, these resources provide the
ecosystem services that provide better quality to human life. Natural
resources provide fundamental life support, in the form of both
consumptiv e and public -good services. Ecological processes maintain soil
productivity, nutrient recycling, the cleansing of air and water, and
climatic cycles. For successful Natural Resource Management, Natural
resource accounting is essential tool. But Natural res ource accounting is a
discipline which is still in an experimental stage at the moment. This is an
accounting with a particular focus on material and energy flow
information and environmental cost information.
Natural resource accounting can be used for:
 Demonstration of accountability for the management and protection of
natural resources; Identifying environmental problems such as
resource depletion;
 Analysing government policy;
 Undertaking resource management and decision -making;
 Monitoring Sustainable Development;
 Drawing up (Macro -Economic) indicators for environmental
performance or prosperity;
 Improving benchmark for measuring a country's National Product
Problems or constraints of Natural Resource Accounting
Natural resource accounting has been affe cted by not only practical
problems it is also the subject of fierce debate about the most suitable
methodologies.

One of the most contentious issues is, for example, whether or not natural
resource accounting should lead to the generation of a figure for the 'green'
national product, i.e. a totally new indicator, or whether the compilation of
an account is in itself sufficient. If the answer is that one needs to have a munotes.in

Page 19

Environmental Curve, Natural
Resources and Green
Accounting
19 figure for a green national product, the next question arises is whether the
figure cal culated should be that for the net or the gross national product,
and how it should be arrived at. The various organisations involved in the
debate each take a different view about this.

A further complicating issue is how to assess thevalue of natural r esources
in monetary terms.

The cost of data collection is another potential problem affecting the
compilation of natural resource accounts. This is of particular significance
to those countries which have yet to begin collecting the relevant data. It is
always advisable to perform a cost -benefit analysis of the situation before
starting to collect new data. The chief factor determining the degree of
benefit is the use that is made of the data. The high cost of obtaining new
data has led some countries to decide in practice to work with estimates
rather than actual figures.

This is one of the toughest nuts to crack, as it requires not only
information on quantities, but also qualitative data on each particular
resource, e.g. water. In addition, the way in which each resource is used(in
the case of fresh water, for example, whether this is as drinking water, to
fill natural lakes and rivers, as an aquatic habitat for fish or as cooling
water for power stations) also affects the value assigned to it. Finally ,
account needs to betaken of the impact which a certain degree of pollution
of the resource in question may have on public health. The difficulty of
valuation is exacerbated by the absence in many cases of a market price
for the resource (e.g. clean air).

The following diagram (Figure 3), which originates from the World Bank,
shows how the valuation of natural resources and environmental
degradation can result in the production of a natural resource account
(otherwise known as an environmental account).

The table gives a clear indication of the steps which have to be taken,
taking a conventional account as the starting point, in order to compile a
natural resource account (i. e. an environmental account) in either physical
terms (see column A)or monetary terms (see column C). The monetary
version of the natural resource account can then be used to draw up an
adjusted version of the national accounts (see bottom row).
2.4.2 Green Accounting
The Net National Product (NNP) is known as the best welfare measure
under standard national income accounting. But the present system of
national accounting i.e. NNP fails as a measure of sustainable
development as it does not take into accou nt the use an abuse of natural
resources. While considering the allowances for consumption of capital in
calculating NNP, it gives consideration only to depreciation of men -made
capital and ignores depreciation of natural resources – non -renewable,
renewab le resources, pollution etc.
The present accounting system suffers from certain deficiencies. These
are:
 The NNP takes note of only such production and consumption
processes where there is market price.
 It does not impute the values of environmental goods and services
used in production process and
 It also does not consider any allowance for depreciation/degradation or
depletion of natural resources.
Therefore, the concept of green accounting of NNP arises from a concern
that an economic indicator such as NNP doesn’t reflect the depreciation
and degradation of environment. This may lead to incorrect development
divisibility. Green national income accounting takes into consideration the
environmental and ecological loss arising out of the developmental effor t
while calculating the national income. Green national income is
environmentally sustainable income of the economy.
The Green accounting of income is an attempt or method to correct the
present measure of NNP for use and above of natural and ecological
resources to arrive at sustainable income which can be a measure or
indicator of sustainable development.
The improvement in the methods of accounting were debated in the 1992
United Nations conference on Environment and development (UNCED)
held at Rio de Je nerio, which recommended all nations to develop a
system of Integrated Environmental and Economic Accounting
(IEEA) - which came to be known as Green Accounting.
A sustainable path has the characteristic that along it the overall
productive capacity is not reduced, what we need to know is at each
movement how much of this productive base we can use up. This is given
by environmentally adjusted NNP. NNP is the total income earned by the
economy less allowances for the depreciation of man -made capital. munotes.in

Page 21

Environmental Curve, Natural
Resources and Green
Accounting
21 ENP = G NP –Depreciation of man -made capital -depreciation of natural
capital.
ENP is a good measure of sustainable development.
Environmentally adjusted NNP(ENP) is the annual pay -off from our total
capital stock (Man -made and natural)
ENP will rise if the total c apital rises or as technology improves. So, the
indicator of sustainable development is whether the ENP is rising or
falling. The development is sustainable if the ENP is rising and vice -versa.
In practice, it is difficult to develop an accounting for natu ral resources.
Parikh and Parikh (1997) elaborated on the system of Environment and
Economic accounting as developed by the United Nations and provided a
definition of Green NNP as –Green NNP = Value of consumption of
natural goods and services + value of production of natural collected (such
as fuelwood, biogas) + value of environmental amenities provided by
environmental resources stocks ( such as clean air, top soil) + value of
leisure enjoyed (Say in enjoying aesthetic beauty of wildlife revenue) +
value of net additions to production of capital + value of net addition to
natural capital stock + value of addition to stocks of defensive capital
(such) as water purifier).
Thus, NNP is the total income earned by the economy in any year, less an
allowance fo r the depreciation of manmade capital.
Green NNP or environmentally adjusted NNP is a good measure of
sustainable development.
Thus, Green NNP is the annual pay -off from our total capital stock
(manmade + natural). ENP can rise over time if this total capi tal stock
rises and /or as technology improves. According, Hartwick rule, the total
stock of capital can be maintained by reinvesting hoteling rents (price -
MC) from optimal non -renewable resources infraction planning new
natural or manmade capita. So, the indictor of sustainability is non -
declining ENP, or whether ENP is rising or falling. It ENP is falling, and
then society’s sustainable level of income is falling too. Development is
unsustainable.
The best measure of sustainable development is Green Accou nt.
2.5 SUMMARY
This unit discussed about the relationship between the environment and
development in the light of Kuznets curve hypothesis which argued that
there is an inverted U -shaped relationship between the two. It also
analysed and discussedtypes an d importance of Natural resources,
problems of Common Property resources, Natural Resource Management
and finally green accounting. Natural resource management is need of the
hour and the unit tries to overview it. Natural Resource Management
refers to the sustainable utilization of major natural resources, such as munotes.in

3.1 INTRODUCTION
Like any other discipline, environmental economics also has its own basic
conce pts, theories and analytical tools, which constitute its foundation.
Most of its concepts and theories are drawn from microeconomics, welfare
economics and macroeconomics. To appreciate the utility and relevance of
environmental economics and to use it in practical life, it is necessary for
us to clearly define and understand its basic concepts and theories.
We, as individuals interact with the environment every day in some way
or the other. We inhale oxygen from the environment and release carbon
dioxide into it, we eat food directly either obtained from the environment
or produced using environmental resources, and we dispose wastes into
the environment. In short, we depend on the environment for our survival,
growth and development. Our attitude towards the environment and our
decisions relating to consumption and provision of environmental goods
and services affect the quality of the environment. Hence, it is necessary
for us to understand the factors that affect individual behaviour and
decisions as the y relate to the environment to diagnose the root causes of
environmental problems and identify appropriate remedial measures.
Demand and supply are the two most important concepts in munotes.in

Page 24

Environmental Economics
24 microeconomics useful in understanding and explaining the behaviour of
individuals. The theory of consumer behaviour attempts to explain why an
individual demands more or less of a commodity and demands something
and not the other. The theory of firm, or the theory of production explains
why a producer produces more, or less of a commodity and why and how
much he offers to sell in the market.
3.2 ENVIRONMENTAL GOODS AND SERVICES
Environmental goods and services (EGS) can directly improve the quality
of life for citizens by providing a cleaner environment and better access to
safe water, sanitation or clean energy. In addition, the use of
environmental goods can reduce harmful side -effects of various activities
that damage the environment and are hazardous to human health and can
help make the use of energy significantly more effi cient.
Environmental goods are typically non -market goods , including clean
air, clean water, landscape, green transport infrastructure (footpaths, cycle
ways, greenways, etc.), public parks, urban parks, rivers, mountains,
forests, and beaches. Environment al goods are a sub -category of public
goods.
Environments services refers to the qualitative functions of natural assets
of land, water and air. The three basic types of environmental services are
disposal services, which reflect the functions of the natur al environment as
an absorptive sink for residuals, productive services, which reflect
economic functions, and consumer or consumptive services, which
provide for the physiological and recreational needs of humans.
Environmental services include the provis ion of raw materials and energy
used to produce goods and services, as well as the removal of waste from
human activities, and their role in life support and landscape maintenance.
The environmental services concepts captures the broad idea that the
natura l environment incorporates many uses or benefits that can be termed
as services.
Environmental goods and services are products that are manufactured or
services rendered for the main purpose of:
 preventing or minimising pollution, degradation or natural re sources
depletion;
 repairing damage to air, water, waste, noise, biodiversity and
landscapes;
 reducing, eliminating, treating and managing pollution, degradation
and natural resource depletion;
 carrying out other activities such as meas urement and monitoring,
control, research and development, education, training, information
and communication related to environmental protection or resource
management. munotes.in

25 3.2.1 Types of Environmental Goods and Services
A. Pure Public / Collective Goods
Most na tural resources and environmental amenities are public goods,
ranging from environmental quality and watershed protection to ecological
balance and biological diversity. Public goods range in geographical scope
from local or regional to national or global. For example, biological
diversity is an international public good since it is not possible (or
desirable) to exclude other nations from benefiting from its conservation.
Therefore, it is unreasonable to expect such goods to be provided in
sufficient quant ities by an individual country in a free market.
A public good is characterised by jointness in supply, in that to produce
the good for one consumer it is necessary to produce it to all consumers.
In many cases, no individuals can be excluded on enjoyment of a public
good (for example, national defence) whether they pay for it or not.Since
nobody can or should be excluded from the benefits of a public good,
consumers would not voluntarily pay for it and hence, no firm would find
it profitable to produce su ch a good, as it is not possible for it to cover its
production cost through the market. Thus, the market mechanism would
fail to supply a public good, although the good has very high utility and
would contribute to social welfare. Thus, a free market wil l lead to
underproduction of public goods. Environmental goods belong to the
entire community and there are no individual rights of ownership. They
are consumed simultaneously by a large number of people. Unlike the case
of private goods, the consumption o f public goods or use of IT services by
one person does not diminish its quantity for availability to others. to sum
up there are three main characteristics of public goods:
a. Non excludability
b. Non – rivalrous consumption
c. Indivisibility
Non- excludability means that nobody can be excluded from consuming a
public good and no market can exist for it and therefore provision must be
made by the government, financed by taxation, for example defence,
roads, street lights, lighthouses, eradication of diseases, cle an air and water
and so on.
A rigorous definition of pure public/ collective good, or a pure non
collective/ private good can be given as follows:
X 1 = a1X
X 2 = a2X
X n = anX
munotes.in

Page 26

Environmental Economics
26 Where X is the total quantity of the good X and X 1, X 2, ..., X n are the
quantities of the good consumed by persons 1,2, …n and a 1, a2, …, a n are
the production of the good consumed by the persons 1,2, …, n. For a pure
public good, a 1 = a 2, …, an=1, and for a pure private good a 1 = a 2, …,
an=0, except for one person (a i), whose proportion equals to 1, i.e., a i=1.
Examples of environmental goods and services that are pure public/
collective goods include solar radiation, biodiversity, conservation, ozone
layer and their sheds
B. Mixed Collective goods:
Some of the environmental good s and services are mixed collective
goods. A mixed collective good is one which, like a pure collective good,
is used in common bi a large number of individuals and from whose use
free Riders cannot be easily excluded, and whose use like that of private
good, is sub tractable, that is its use by one of the co - users to that extent.
Thus, mixed collective goods have one characteristic each in common
with pure collective goods and private, or non -collective goods. Examples
of environmental goods and serv ices that are mixed public/ collective
goods include wildlife, marine fish, recreational services of lakes and
several watershed services.
3.3 EXTERNALITIES AND MARKET FAILURE:
Market Failure arises when the outcome of an economic transaction is
not comp letely efficient, meaning that all costs and benefits related to the
transaction are not limited to the buyer and the seller in the transaction.
Individual consumers will often purchase goods with an environmental
component to make up for their inability t o directly purchase
environmental goods, thus revealing the value they hold for certain aspects
of environmental quality. For example, someone may buy a cabin on a
lake in order to enjoy not only the home itself but also the lake’s
pristine environment . If the individual could exclusively capture the
environmental benefits that result from owning the cabin, the demand for
cabins would reflect the full value of both the home and the environmental
goods it provides, and the market for cabins would be efficien t.
Unfortunately, in the case of environmental goods, markets often fail to
produce an efficient result, because it is rare that any one individual can
incur the full benefit, as well as the cost, of a particular level of
environmental quality. That is bec ause environmental goods commonly
suffer from the presence of externalities (that is, consequences that no one
pays for) or a lack of property rights .
Externalities
Private markets offer an efficient way to put buyers and sellers together
and determine wha t goods are produced, how they are produced, and who
gets them. The principle that voluntary exchange benefits both buyers and
sellers is a fundamental building block of the economic way of thinking. munotes.in

Page 27

Micro Foundations of
Environmental Economics - I
27 But what happens when a voluntary exchange affects a thi rd party who is
neither the buyer nor the seller?
Consider, for example, a concert producer who wants to build an outdoor
arena that will host country music concerts a half -mile from your
neighborhood. You will be able to hear these outdoor concerts while
sitting on your back porch —or perhaps even in your dining room. In this
case, the sellers and buyers of concert tickets may both be quite satisfied
with their voluntary exchange, but you have no voice in their market
transaction.
The effect of a market exc hange on a third party who is outside, or
external, to the exchange is called an externality . Because externalities that
occur in market transactions affect other parties beyond those involved,
they are sometimes called spillovers .
There are two types o f externalities: Negative and Positive.
Negative Externality exists when individuals bear a portion of the cost
associated with a good’s production without having any influence over the
related production decisions. For example, parents may have to pay hi gher
health -care costs related to pollution -induced asthma among their children
because of increased industrial activity in their neighborhood. Producers
do not consider those costs to others in their decisions. As a result, they
produce more goods with n egative externalities than is efficient, which
leads to more environmental degradation than is socially desirable.
Positive Externalities also result in inefficient market outcomes.
However, goods that suffer from positive externalities provide more value
to individuals in society than is taken into account by those providing the
goods. An example of a positive externality can be seen in the case of
college roommates sharing an off -campus apartment. Though a clean
kitchen may be valued by all the individual s living in the apartment, the
person who decides to finally wash the dishes and scrub the kitchen floor
is not fully compensated for providing value to all the roommates.
Because of that, the decision to clean the kitchen undervalues the benefits
of such an action and the kitchen will go uncleaned more often than is
socially desirable. Such is the case with environmental quality. Because
markets tend to undervalue goods with positive externalities, market
outcomes provide a level of environmental quality t hat is lower than is
socially desirable.
Key Points
 Economic production can cause environmental damage. This tradeoff
arises for all countries, whether high -income or low -income, and
whether their economies are market -oriented or command -oriented.
 An exter nality , sometimes called a spillover , occurs when an
exchange between a buyer and seller has an impact on a third party
who is not part of the exchange. Externalities can be positive or
negative. munotes.in

Page 28

Environmental Economics
28  Market failure is when the market does not allocate resource s on its
own efficiently in a way that balances social costs and benefits;
externalities are one example of a market failure.
 Social costs are costs that include both the private costs incurred by
firms and also additional external costs incurred by third parties
outside the production process.
Pollution
From 1970 to 2012, the population of the United States increased by one -
third and the size of the US economy more than doubled. Despite this
growth, the United States, using a variety of anti -pollution poli cies, has
made genuine progress against a number of pollutants.
According to the US Energy Information Administration, the emissions of
certain key air pollutants declined substantially from 2007 to 2012; in fact,
they dropped 730 million metric tons a yea r—a 12% reduction. This
seems to indicate that progress has been made in the United States in
reducing overall carbon dioxide emissions, which cause greenhouse gases.
Despite the gradual reduction in emissions from fossil fuels, many
important environmenta l issues remain. Along with the still -high levels of
air and water pollution, other issues include hazardous waste disposal,
destruction of wetlands and other wildlife habitats, and the impact of
pollution on human health.
Pollution as a negative externali ty
Pollution is a negative externality. Economists illustrate the social costs of
production with a demand and supply diagram. The social costs include
the private costs of production incurred by the company and the external
costs of pollution that are pas sed on to society.
The diagram below shows the demand and supply for manufacturing
refrigerators. The demand curve, \text{D} Dstart text, D, end text, shows
the quantity demanded at each price. The supply curve, \text{Sprivate}
Sprivate start text, S, p, r, i, v, a, t, e, end text, shows the quantity of
refrigerators supplied by all the firms at each price if they are taking only
their private costs into account and they are allowed to emit pollution at
zero cost. The market equilibrium, \text{E0} E0start text, E, 0, end text,
where quantity supplied and quantity demanded are equal, is at a price of
$650 and a quantity of 45,000. You can find this same information in the
first three columns of the table below as well. munotes.in

Environmental Economics
30 The situation is not actually that simple, however. Pollution is created as a
byproduct of the metals, plastics, chemicals, and energy that are used in
manufacturing refrigerators. Let’s say that, if these pollutants were emitted
into the air and water, they would create costs of $100 per refrigerator
produ ced. These costs might occur because of injuries to human health,
impact on property values, destruction of wildlife habitat, reduction of
recreation possibilities, or because of other negative impacts.
In a market with no anti -pollution restrictions, firm s can dispose of certain
wastes at no cost. Now imagine that firms that produce refrigerators must
factor in these external costs of pollution —that is, the firms have to
consider not only the costs of labor and materials needed to make a
refrigerator but a lso the broader costs to society from pollution. If the firm
is required to pay $100 for the additional external costs of pollution each
time it produces a refrigerator, production becomes costlier and the entire
supply curve shifts up by $100.
Notice the fourth column of the table above. Taking external costs of
pollution into account, the firm will need to receive a price of $700 per
refrigerator and produce a quantity of 40,000. Remember that supply
curves are based on choices about production that firms make while
looking at their marginal costs; demand curves are based on the benefits
that individuals perceive while maximizing utility. If no externalities
existed, private costs would be the same as the costs to society as a whole,
and private benefits w ould be the same as the benefits to society as a
whole. Thus, if no externalities existed, the interaction of demand and
supply would coordinate social costs and benefits.
But the reality is that externalities do exist. Because of this, a supply curve
show ing private costs doesn't actually represent all social costs.
Because externalities represent a case where markets no longer consider
all social costs but only some of them, economists commonly refer to
externalities as an example of market failure . When there is market
failure, the private market fails to achieve efficient output because either
firms do not account for all costs incurred in the production of output
and/or consumers do not account for all benefits obtained, in the case of a
positive extern ality. In the case of pollution, at the market output, social
costs of production exceed social benefits to consumers, and the market
produces too much of the product.
There's a general concept here. If firms are required to pay the social costs
of polluti on, they create less pollution but produce less of the product and
charge a higher price.
Corrective instruments
Once the market inefficiency relating to a particular environmental good is
understood, policy makers can correct for the inefficiency by emplo ying
any number of instruments. Regardless of the instrument, the goal is to
provide incentives to individual consumers and firms so that they will
choose a more efficient level of emissions or environmental quality. munotes.in

31 Command and Control
Command and contro l is a type of environmental regulation that allows
policy makers to specifically regulate both the amount and the process by
which a firm should maintain the quality of the environment. Often it
takes the form of a reduction of emissions released by the f irm during the
production of its goods. This form of environmental regulation is very
common and allows policy makers to regulate goods where a market -
based approach is either not possible or not likely to be popular.
Summary
 Economic production can cause environmental damage. This tradeoff
arises for all countries, whether high -income or low -income, and
whether their economies are market -oriented or command -oriented.
 An externality , sometimes called a spillover , occurs when an exchange
between a buyer and seller has an impact on a third party who is not
part of the exchange. Externalities can be positive or negative.
 Market failure is when the market does not allocate resources on its
own efficiently in a way that balances social costs and benefits;
externa lities are one example of a market failure.
 Social costs are costs that include both the private costs incurred by
firms and also additional external costs incurred by third parties
outside the production process.
3.4 SOCIAL COST -BENEFIT ANALYSIS
The notion that a zero pollution objective is not necessarily ideal policy is
one of the more difficult concepts for environmental economists to
convey. After all, if pollution is bad shouldn’t we design policy to
completely eliminate it? Many of us are drawn to the field based on a
genuine concern for the environment and the belief that economics
provides a powerful tool for helping solve environmental problems. Yet
we are often in the position of recommending policies that appear on the
surface to be anti -environmental. How can these observations be
reconciled? The answer lies in understanding scarcity: we have unlimited
wants, but live in a world with limited means. Economists in general study
how people make decisions when faced with scarcity. Scarcity impli es that
resources devoted to one end are not available to meet another; hence
there is an opportunity cost of any action. This includes environmental
policy. For example, funds used by a municipality to retrofit its water
treatment plant to remove trace am ounts of arsenic (a carcinogen) cannot
also be used to improve local primary education. Environmental
economists are tasked with recommending policies that reflect scarcity of
this type at the society level. For both individuals and societies scarcity
necessitates trade -offs, and the reality of trade -offs can make the complete
elimination of pollution undesirable. Once this is acknowledged the
pertinent question becomes how much pollution should be eliminated. munotes.in

Environmental Economics
32 How should we decide? Who gets to decide? To he lp provide answers
economists use an analytical tool called cost -benefit analysis.
Cost-benefit analysis provides an organizational framework for
identifying, quantifying, and comparing the costs and benefits (measured
in dollars) of a proposed policy acti on. The final decision is informed
(though not necessarily determined) by a comparison of the total costs and
benefits. While this sounds logical enough, cost -benefit analysis has been
cause for substantial debate when used in the environmental arena. The
benefits of environmental regulations can include, for example, reduced
human and wildlife mortality, improved water quality, species
preservation, and better recreation opportunities. The costs are usually
reflected in higher prices for consumer goods and /or higher taxes. The
latter are market effects readily measured in dollars, while the former are
nonmarket effects for which dollar values are not available. In addition to
complicating the practice of cost - benefit analysis (monetary values for the
nonma rket effects must be inferred rather than directly observed) this
raises ethical issues. Should we assign monetary values to undisturbed
natural places? To human lives saved? To the existence of blue whales and
grey wolves? If we decide such things are too ‘priceless’ to assign
monetary values we lose the ability to use cost -benefit analysis to inform
the decision. What then is the alternative? How do we decide? Who gets to
decide?
Environmental economists tend to favour cost -benefit analysis in the
policy arena because of the discipline and transparency it provides in
evaluating policy options. It is easy to evaluate absolutes. Most would
agree that reducing nitrogen contamination of groundwater wells, limiting
the occurrence of code red ozone alerts, and p reserving habitat for grizzly
bears are worthy goals. Determining the relative merits of any one of these
compared to the others, or compared to non -environmental goals such as
improving public education, is much more daunting. Because policy
making is ult imately about evaluating the relative merits of different
actions some mechanism is needed to rank the alternatives. Without the
discipline of cost - benefit analysis it is not clear how the interests, claims,
and opinions of parties affected by a proposed regulation can be examined
and compared. Criterion such as ‘moral’ or ‘fair’ do not lend themselves
well to comparison and are subject to wide ranging interpretation. Who
gets to decide what is moral or fair? Cost -benefit analysis is far from
perfect, but it demands a level of objectivity and specificity that are
necessary components of good decision making.
Advantages of CBA
 A variety of different impacts can be measured in the same units
 Can be used as a device for determining where limited funding and re sources
should be directed.
 Takes into account both direction and intensity of preferences. munotes.in

Page 33

Micro Foundations of
Environmental Economics - I
33  Allows us to emphasize both the economic value of environmental protection
as well as the opportunity cost of protecting the environment
Problems of CBA
 How to d etermine value for the environment? Is it immoral to place
monetary values on things such as wildlife?
 It is very difficult to predict the effects of a single change on an entire
ecosystem. An understanding of the ripple effects of a certain policy on the
environment is often uncertain.
 Is it appropriate to discount future costs and benefits and if so, what should
the discount rate be?
 Can the CBA be manipulated to reflect the interests of firms? CBA does not
test sustainability.
 So does CBA, with disco unted benefits and costs, give future generations the
short shrift?
3.5 SUMMARY
 Environmental goods and services (EGS) can directly improve the quality of
life for citizens by providing a cleaner environment and better access to safe
water, sanitation or clean energy. In addition, the use of environmental goods
can reduce harmful side -effects of various activities that damage the
environment and are hazardous to human health and can help make the use of
energy significantly more efficient.
 An externality , sometimes called a spillover , occurs when an
exchange between a buyer and seller has an impact on a third party
who is not part of the exchange. Externalities can be positive or
negative.
 Market failure is when the market does not allocate resources on its
own efficiently in a way that balances social costs and benefits;
externalities are one example of a market failure.
 Cost-benefit analysis provides an organizational framework for identifying,
quantifying, and comparing the costs and benefits (measured in dollars) of a
proposed policy action. The final decision is informed (though not
necessarily determined) by a comparison of the total costs and benefits

4.1 INTRODUCTION
Like any other discipline, environmental economics also ha s its own basic
concepts, theories and analytical tools, which constitute its foundation.
Most of its concepts and theories are drawn from microeconomics, welfare
economics and macroeconomics. To appreciate the utility and relevance of
environmental econom ics and to use it in practical life, it is necessary for
us to clearly define and understand its basic concepts and theories.
4.2 THE EQUI -MARGINAL PRINCIPLE
A Model of a Single Polluting Firm
Consider a polluting firm that faces an increasing marginal po llution
abatement cost curve. Left unregulated it will choose to abate zero units of
carbon and avoid the abatement costs represented by the area underneath
the marginal abatement cost curve: B + C + D. Suppose a benefit -cost munotes.in

Page 36

Environmental Economics
36 analysis has determined that o ptimal abatement occurs at the blue dot
where the marginal benefit and marginal cost curves intersect. The
resulting level of emissions is e*
(measured right to left along the horizontal axis).

Fig. 4. 1
Carbon Tax
One way to achieve this level of abatement is to set a tax where marginal
benefit equals marginal abatement cost -- represented by the horizontal
"tax" line. The polluting firm will notice that it is cheaper to abate carbon
emissions as long as the marginal abatement cost is lower than the tax.
Since the tax bill (A + B) is great than the marginal abatement cost bill (B)
to the left of the vertical "cap" line the firm will choose to abate. To the
right of the "cap" line the marginal abatement cost bill (C + D) is greater
than the tax bill (D) so th e firm will choose to pay the tax and continue to
pollute.
Results:
 The efficient abatement level is achieved: e*
 The abatement cost to the pollution firm = B + D
 Government revenue = D
Carbon Cap
Another way to achieve this level of abatement is to set a cap where
marginal benefit equals marginal abatement cost -- represented by the
vertical "cap" line. The polluting firm must abate its carbon emissions
to e*.
Results:
 The efficient abat ement level is achieved: e*
 The abatement cost to the pollution firm = B

37 A Model with Two Polluting Firms
Now things get a bit more hairy. A two -panel diagram is needed to better
understand the logic of trading The two -panel diagram illustrates the
increas ing marginal abatement costs of two firms. One has an old, dirty,
plant with high abatement costs (in blue) that goes right to left with
abatement. The other firm has a newer plant that has lower abatement
costs (in green) that goes left to right with abat ement. The width of the
horizontal axis is the abatement that must be achieved to reduce overall
emissions to the efficient level.



Fig. 4.2
The intersection of the two marginal abatement costs is where economic
efficiency is achieved. This is known as the "equimarg inal principle." The
total costs of achieving the efficient abatement/emissions level is: C + G +
K. The efficient emissions level, e*, shows that the low abatement cost
firm should reduce more emissions than the high abatement cost firm.
Carbon Tax
One wa y to achieve this level of abatement is to set a tax where the
marginal abatement costs are equal -- assuming that we have this
information (we don't but we can iterate towards the intersection) --
represented by the horizontal "tax" line. As above, the po lluting firms will
notice that it is cheaper to abate carbon emissions as long as the marginal
abatement cost is lower than the tax.
The high cost firm will abate to e* (right to left) and suffer abatement
costs of K and pay a tax bill to the government eq ual to B + C + F + G.
The low cost firm will abate to e* (left to right) and suffer abatement costs
of C + G and pay a tax bill to the government equal to J + K.
munotes.in

Page 38

Environmental Economics
38 Results:
 The efficient abatement level is achieved: e*
 The abatement cost to the polluting fir ms, C + G + K, is
minimized
 Government revenue = B + C + F + G + J + K
Carbon Cap -and-Trade
Another way to achieve this level of abatement is to set a carbon cap by
issuing carbon permits to polluting firms. Each permit gives the firm the
right to emit one unit of carbon. If we don't have the political will to go
ahead and give more permits to the high cost firm (in order to achieve
efficiency) we can do it "fairly" by giving each firm the same amount of
permits -- represented by the vertical "cap" line. Th e abatement cost to the
low abatement cost firm is equal to area C. The abatement cost to the high
abatement cost firm is D + F + G + K.
At some point the high cost firm might rather have a permit than pay those
high costs. If it recognizes that its margin al abatement cost is higher than
the marginal abatement cost of the low cost firm it could propose a trade.
In effect, the blue line over area D, F and G is a demand curve for permits
and the green line is a supply curve for permits. Anywhere in between th e
blue and green line is a permit price that is mutually agreeable between
both firms. A competitive permit market will result in a permit price
equivalent to the efficient carbon tax. Trading reduces overall abatement
costs by area D + F.
Results:
 The eff icient abatement level is achieved: e*
 The abatement cost to the polluting firms, C + G + K, is minimized
Conclusions
In terms of the market failure, the negative carbon externality, both a
carbon tax and carbon cap -and-trade will achieve the same level o f
increased efficiency by achieving the optimal abatement level at the
minimum cost. The only difference is the distributional implications. The
cost to the firm is lower for carbon cap -and-trade. The government
receives tax revenue with a carbon tax. Both policies are preferred over
technological or output standards (i.e., command and control regulation).
4.3 ECONOMIC EFFICIENCY
Economic efficiency implies an economic state in which every resource is
optimally allocated to serve each individual or entity i n the best way while
minimizing waste and inefficiency. munotes.in

Page 39

Micro Foundations of
Environmental Economics -II
39 When an economy is economically efficient, any changes made to assist
one entity would harm another.In terms of production, goods are produced
at their lowest possible cost, as are the variable inputs of production.
Some terms that encompass phases of economic efficiency include
allocative efficiency, productive efficiency, distributive efficiency, and
Pareto efficiency. A state of economic efficiency is essentially theoretical;
a limit that can be app roached but never reached.
Instead, economists look at the amount of loss, referred to as waste,
between pure efficiency and reality to see how efficiently an economy
functions.
The principles of economic efficiency are based on the concept that
resources are scarce. Therefore, there are not sufficient resources to ensure
that all aspects of an economy function at their highest capacity at all
times. Instead, scarce resources must be distributed to meet the needs of
the economy in an ideal way while also li miting the amount of waste
produced. The ideal state is related to the welfare of the population with
peak efficiency also resulting in the highest level of welfare possible based
on the resources available.
Productive firms seek to maximize their profits by bringing in the most
revenue while minimizing costs. To do this, they choose the combination
of inputs that minimize their costs while producing as much output as
possible. By doing so, they operate efficiently; when all firms in the
economy do so, it i s known as productive efficiency.
Consumers, likewise, seek to maximize their well -being by consuming
combinations of final consumer goods that produce the highest total
satisfaction of their wants and needs at the lowest cost to them. The
resulting consum er demand guides productive (through the laws of supply
and demand) firms to produce the right quantities of consumer goods in
the economy that will provide the highest consumer satisfaction relative to
the costs of inputs. When economic resources are allo cated across
different firms and industries (each following the principle of productive
efficiency) in a way that produces the right quantities of final consumer
goods, this is called allocative efficiency.
Finally, because each individual values goods dif ferently and according to
the law of diminishing marginal utility, the distribution of final consumer
goods in an economy are efficient or inefficient. Distributive efficiency is
when the consumer goods in an economy are distributed so that each unit
is co nsumed by the individual who values that unit most highly compared
to all other individuals. Note that this type of efficiency assumes that the
amount of value that individuals place on economic goods can be
quantified and compared across individuals

Fig. 4.3 Economic and Social efficiency
Intersection of S and D is a point of economic efficiency Fig 4.3 . To the
right of the intersection output would be more than what is required for
economic efficiency. There would be an excess demand or a deficient
supply for the product. To the left of the intersection, the output would be
less than what is economically efficient as there would be excess supply or
deficit demand for the product.
4.4 DAMAGE COST & ABATEMENT COST
Pollution damage costs
Even if it is technologically feasible to get rid of all pollutants from a
given environmental medium, such an undertaking may be difficult to
justify on the basis of cost considerations. However, when the volume of
waste discharged exceeds the assimilative capacity of the environment,
and is left untreated, it can contribute to a deterioration in environmental
quality. The total monetary value of all the various damages resulting from
the discharge of untreated waste into the environment is referred to as
pollution damage cost.
Such damage to envi ronmental quality may be manifested in a variety of
ways, largely depending on the amount and the nature of the untreated
waste. For example, when biodegradable pollutants, such as sewage,
phosphate -containing detergents and feedlot waste are emitted into a lake,
they can lead to the development of a process known as eutrophication.
Over time, the outcome of this process is to cover a substantial portion of
the lake with green substances composed mainly of algae and weeds. One
immediate effect is the reduct ion of the scenic appeal of the lake. In
addition, there is a negative impact on the population of aquatic
organisms, because the ability of a body of water to support fish and other
organisms depends on how much dissolved oxygen it contains. Thus, if
biodegradable pollutants were discharged into a lake and left untreated,
the damage to environmental quality would be identified in terms of munotes.in

Page 41

Micro Foundations of
Environmental Economics -II
41 reduced scenic attraction and decreased population of certain aquatic
organisms, such as fish. The monetary value of th ese adverse
environmental effects constitutes pollution damage cost.
The identification and estimation of pollution damage costs are even more
complicated in the case of persistent pollutants. Examples of such
pollutants include toxic metals, such as lead and mercury, radioactive
wastes, and inorganic compounds such as some pesticides and waste
products produced by the petrochemical industry. What is particularly
significant about these types of pollutants is not the mere fact that they are
patently danger ous to living organisms and the ecosystem as a whole, but
the fact that because of their very slow decomposition process they tend to
persist in the environment for a very long period of time. In other words,
their adverse environmental effects transcend p resent action. For example,
radioactive elements leaking from nuclear power plants today will have
detrimental effects over several generations. This makes the estimation of
damage costs arising from persistent pollutants extremely difficult.
In general, t hen, pollution damage costs are identified in terms of the
losses of or damage to plants and animals and their habitats; aesthetic
impairments; rapid deterioration to physical infrastructures and assets; and
various harmful effects on human health and mort ality. In order to
estimate damage costs, however, we need to go beyond the physical
account of damage. More specifically, the damage identified in physical
terms needs to be expressed in monetary terms as much as possible.

Figures 4.4a and 4.4b
As the above discussions indicat e, the estimation of pollution damage
costs is a formidable task and requires a good deal of imagination and
creative approaches. Furthermore, other factors being equal, the more
persistent the pollutants, the harder the task of evaluating damage costs. In
fact, some aspects of pollution damage are simply beyond the realm of
economic quantification. Regardless of these difficulties, pollution
damage does occur. Hence, as a society striving for a better life, we need
to develop a procedure that will provide us with a framework designed to
enhance our understanding of pollution damage costs. munotes.in

Page 42

Environmental Economics
42 Conceptually, Figures 4.4a and 4.2b are two alternative representations of
the general characteristics of the marginal pollution damage cost (MDC).
As with the MCC curv es, the only difference between these two figures is
in the labeling of the x -axis. A basic assumption in the construction of
these curves is that damage cost is an increasing function of pollution
emissions. In other words, the damage caused by a unit of pollution
increases progressively as the amount of pollution (untreated waste)
emitted increases. As the numerical example in Figure 10.2a indicates, the
marginal damage cost increases from $125 (the cost of the tenth unit of
waste) to $500 (the cost of th e fifteenth unit of waste) as the amount of
waste emissions increases from 10 to 15 units. This is, of course, in accord
with the ecological principle discussed in Chapters 4 and 5 of a cumulative
(nonlinear) effect of pollution on the environment.
It is a lso important to note that these two alternative presentations offer
different interpretations regarding the damage cost curve. In Figure 10.2a,
as discussed above, the damage cost curve measures the social cost of the
damage to the environment in monetary terms, resulting from each
additional unit of waste emission. This cost increases as the volume of
waste emitted increases. On the other hand, the damage cost curve
represented by Figure 10.2b depicts the amount society is willing to pay to
avoid damage ( or cleanup) at the margin. In other words, it measures
society’s willingness to pay for improved environmental quality on an
incremental basis, or the demand for environmental quality.
Pollution control (abatement) costs:
Pollution control (abatement) cos ts represent direct monetary expenditures
by a society for the purpose of procuring resources to improve
environmental quality or to control pollution. Expenditures on sewage
treatment facilities, smokestacks, soundproof walls and catalytic
converters on p assenger cars are just a few examples of pollution control
costs. These expenditures may be incurred exclusively by private
individuals, such as expenditures on soundproof walls by residents living
in close proximity to an airport. In contrast, sewage trea tment facilities
may be undertaken as a joint project by local and federal government
agencies. In this case the expenditures are shared by two government
bodies. In some situations, a project may be undertaken by a private firm
with some subsidy from the public sector. Thus, as these examples
illustrate, the bearers of the expenditures on pollution control projects may
vary, and in some instances are difficult to trace. Despite this possible
complication, the conventional wisdom is to view pollution contro l cost in
its entirety. To this extent the specific source of the expenditure is
irrelevant. What is relevant is that all components of the expenditures
attributable to a specific project are fully accounted for, regardless of the
source of the funds.
In general, we would expect the marginal pollution control cost to increase
with increased environmental quality or cleanup activities. This is because
incrementally higher levels of environmental quality require investments
in technologies that are increasing ly costly. For example, a certain level of munotes.in

Page 43

Micro Foundations of
Environmental Economics -II
43 water quality could be achieved through a primary sewage treatment
facility. Such a facility is designed to screen out the solid and visible
material wastes, but nothing more. If a higher level of water quality is
desired, an additional expenditure on secondary or tertiary treatment may
be required. Such additional treatments would require implementation of
new and costly technologies designed to apply either chemical and/or
biological treatments to the water. Grap hically, we can visualize the
marginal control cost (MCC) as follows.

Figures 4.5a and 4.5b
Figures 4.5a and 4.5b are two alternative ways of representing the
marginal pollution control cost in graph form. Before we proceed any
further, it is very important to understand the exact reading of these two
curves. First, as will be evident shortly, the two graphs convey the same
concept, but have different labels on their x -axes. In Figure 4.5a, the x -
axis represents units of untreated waste emitted into the environment, and
in Fi gure 4.5b the same axis represents the units of treated waste or
cleanup. Second, in Figure 4.5a, the marginal cost of the twentieth unit of
waste is indicated to be zero. This number represents the benchmark or
total number of units of waste that is bei ng considered for treatment.
Third, the curves in both figures measure marginal c ost. For example, in
Figure 4.5a, the cost is $200 when the unit of waste emitted is 5. What
exactly does this cost measure? It measures the cost of cleaning up or
controllin g the fifteenth unit of waste. This is because given a benchmark
of 20 units of waste, emission of only 5 units means a cleanup of 15 units
(20–5). In fact, this result is easily con firmed by looking at Figure 4.5b
since the marginal control cost of treat ing the fifteenth unit of waste is
$200. This clearly shows that Figures 4.5a and 4.5b are two different ways
of looking at the same thing. Finally, it is important to note that in both
cases, the marginal pollution control cost increases at an increasin g rate as
a higher level of cleanup or environmental quality is desired. The
numerical example in Figure 10.1b clearly illustrates this. The marginal
cost to control (or treat) the tenth unit of waste is indicated to be $50.
However, the marginal cost is i ncreased to $200, a fourfold rise, to treat
the fifteenth unit of waste. munotes.in

Page 44

Environmental Economics
44 At this stage it is important to specify certain important technological
factors that determine the position of any marginal pollution control cost
curve. More specifically, it is imp ortant to note that the marginal pollution
control cost curves are constructed by holding constant such factors as the
technology of pollution control, the possibility of input switching, residual
recycling, production technology, etc. A change in any one of these
predetermined factors will cause a shift in the entire marginal pollution
control cost curve. For instance, a power company that uses coal as its
primary source of input could reduce pollution (sulfur) emission by
switching from coal with a high s ulfur content to low -sulfur coal. In this
particular case, the effect would be to shift the marginal pollution control
cost downward. Similar results would occur if there were a significant
improvement in pollution control technology, such as the developme nt of
a new and more efficient catalytic converter for automobiles.
Finally, since pollution control costs are explicit or out -of-pocket
expenditures, it is assumed that no apparent market distortion occurs as a
result of a third party effect —that is, an e xternality. In other words, for
pollution control costs, there will be no difference between private and
social costs. However, this is not to suggest that market distortion in the
assessment of pollution control costs cannot exist as a result of either
market imperfection (power) or government intervention.
As stated earlier, pollution control cost accounts for only one side of the
total social costs of pollution. Let us now turn to a detailed examination of
the second component of the total pollution disp osal costs, namely
pollution damage costs.
4.5 ROLE OF INSTITUTIONS IN ENVIRONMENTAL
PROTECTION
The role of national government is critical for control of environmental
pollution control,conservation and improvement of environment for
promoting sustainable development. Toaddress the diverse environmental
issues a number of environment related institutions andorganization have
been set up at international, national level by United Nations, national
governments and civil society. An environmental organization is an
organization seeks toprotect, analyze or monitor the environment against
misuse or degradation or lobby forthese goals. Enviro nmental organization
may be a government organization, a nongovernment organization, a
charity or trust.

Role of Non-Governmental Organizations (NGO) in Environment
Protection!
Today we come across various non -governmental organizations whose
concerns are focused on various areas such as social issues, health issues,
and environmental issues. Non -Governmental Organization is a broad
term, which includes charity organizations, advisory committees and
various other professional organizations. NGOs in India are spread across
the country and they have close contacts with communities.
There are large number of NGOs in India and other countries that are
exclusively working for environmental, protection, conservation, and
aware ness. The number of these non -governmental organizations which
are actively involved in environmental protection in our country is, in fact,
more than in any of the develop ing country. Increasingly, the government
is viewing NGOs not only as agencies that will help them to implement
their programs, but also as partners shaping policy and programs.
Some of the international environmental organizations are Greenpeace,
Worldwide Fund for Nature’ (WWF), Earth First, etc. Let us now have a
detailed dis cussion on some of the environmental organizations and their
efforts in protecting environme nt.
Greenpeace:
Greenpeace is an environment -friendly international organization, which
aims at promoting environmental awareness. It is an independent,
campaigning organiza tion, addressing the environmental abuse through
direct, non -violent confrontation s with governments and companies. It
exposes the global environmental problems and provides solutions for a
healthy environment.
Greenpeace focuses on the most crucial worldwide threats to our planets
biodiver sity and environment. munotes.in

Page 48

Environmental Economics
48 Greenpeace has played an important role in preserving the
environment, which is proved by its successful achievements:
1. A ban on toxic waste exports to less developed countries.
2. A moratorium on commercial whaling.
3. A United Nations convention providing for better managemen t of world
fisheries.
4. A Southern Ocean Whale Sanctuary.
5. A 50 -year moratorium on mineral exploitation in Antarctica.
6. Ban on the dumping at sea of radioactive and industrial waste and
disused oil installations.
7. An end to high -sea, large -scale dri ftnet fishing.
8. A ban on all nuclear weapons testing their first ever campaign.
Worldwide Fund for Nature (WWF) —India:
WWF is an international organization for wildlife conservation with its
focus on protecting particular species of wildlife fauna. As it s range of
activities broadened, the international organization believed that its name
no longer reflected the scope of its activities and became the Worldwide
Fund for Nature in 1986. But the affiliated groups in the United States and
Canada retained the original name. The organization is now simply,
referred to as WWF.
WWF -India is committed to protecting and saving the already degraded
and threat ened natural bounties in the country. The organization is today
dedicated to the con servation of natural hab itats and ecosystems in India.
WWF -India was established as a Charitable Trust in 1969. With its
network of State/Divisional and Field Offices spread across the country to
implement its programs, WWF -India is the largest and one of the most
experienced con servation organizations in the country.
The Secretariat of the orga nization functions from New Delhi. The
organization is part of the WWF family with 27 independent national
organizations. The coordinating body, the WWF International, is located
at Gland in Switzerland.
The WWF -India Mission has five broad program components:
1. Promoting India’s ecological security; restoring the ecological balance.
2. Conserving biological diversity.
3. Ensuring sustainable use of the natural resource base.
4. Minimizing pollution and wasteful consumption, promoting sustainable
lifestyles. munotes.in

49 WWF -India implements its conservation programs through Field
Programs, Public Policy, Education, Communications, NGO Networking,
and Resource Mobilization.
The key environmental issues, which WWF -India has involved itself
with, are:
The tiger conservation program, fresh -water and wetlands program, river
dolphin conservation program, wildlife trade monitoring, managing
forests, environmental law, informa tion management and environmental
education.
Some Other Environmental Organizations in India:
1. The Bombay Natural History Society (BNHS):
Founded in 1883, is recog nized as one of the foremost conservation
research organizations in the world. It aims to collect data on the
specimens on n atural history throughout the Indian sub -continent. To
disseminate knowledge of flora and fauna by means of lectures, field trips,
literature, expeditions and to study wildlife -related problems and rec -
ommend management plans to conserve wildlife and its h abitat.
2. Development Alternatives Group:
Development Alternatives Group based in Delhi works in all parts of the
country. It was established in 1983 to design options and promote sustain -
able development through programs of economic efficiency, equity an d
social justice, resource conservation, and self -reliance. Its activities cover
the entire nation: It is working in the field of pollution monitoring and
control, waste recycling management, wasteland development, and
appropriate technology.
Its objective is to design options and promote sustainable development
through programs of:
i. Economic efficiency,
ii. Equity and social justice,
iii. Environmental harmony,
iv. Resource conservation, and
v. Self -reliance.
3. The Energy Research Institute (TERI):
Established in 1974, is a wholly indepen dent, non -profit research institute.
Its mission is to develop and promote technolo gies, policies, and
institutions for efficient and sustainable use of natural resources. It has
been imparting environmental educat ion through projects, workshops,
audio -visual aids, and quiz competitions. munotes.in

50 It deals with policy -related works in the energy sector, research on
environmental subjects, development of renewable energy technologies
and promotion of energy efficiency in the i ndustry and trans port sector.
TERI also has a major program in biotechnology, the applications of
which are oriented toward increased biomass production, conversion of
waste into useful products and mitigating the harmful environmental
impacts of several economic activities.
4.6 COASE THEOREM
Environmental resources are externality -ridden because they lack a clearly
defined property right. Once this is acknowledged, any effort to internalize
(remedy) environmental externalities requires an effective scheme of
assigning property rights. This indeed captures the essence of the property
rights approach. More specifically, this approach requires that property
rights should be assigned to one of the parties involved in an
environmental dispute. Furthermore, acco rding to Coase (1960), the
assignment of property rights could be completely arbitrary and this would
have no effect on the final outcome of the environmental problem under
consideration.
For example, in the case of environmental pollution, the Coasian ap proach
suggests that the optimal level of pollution can be achieved by an arbitrary
assignment of property rights to either the polluter(s) or the pollutee(s).
This proposition that the assignment of property rights to a specific party
has no effect on the optimal level of pollution is the core concept of what
is widely known as the Coase theorem. To demonstrate the essence of this
theorem in a rather simple manner, we will again use the two familiar
firms: the paper mill and the fish hatchery.

Figure 4.6
As discussed earlier, the problem between these two firms arises because
their economic activities involve the joint use of a river. To demonstrate munotes.in

Page 51

Micro Foundations of
Environmental Economics -II
51 how this problem can be remedied using a property rights approach, let us
start by assuming that the legal rights to the use of the river belong to the
hatchery. Given this, the hatchery, if it wishes, could completely deny the
paper mill access to the river. That is, the paper mill would not be
permitted to use the river to discharge its waste. In Figure 4.6, this
situati on is represented by the origin, where the amount of waste emitted
into the river from the paper mill is zero. This means that the paper mill
has to find an alternative way of disposing the waste from its current
operation —a total of 200 units. The key que stion is, then, will this be a
stable situation? Given the MDC and MCC curves presented in Figure 4.6,
the answer to this question would be a nod for the following reason.
When the waste discharged by the paper mill is less than We, we observe
that MCC (t he incremental cost of cleanup for the paper mill using other
means than the river) is greater than the MDC —the incremental damage
cost to the hatchery. For example, as shown in Figure 11.2, for the
seventieth unit of the waste that is emitted into the riv er, the marginal
damage cost to the hatchery is $20. However, to achieve this same result,
the cost to the paper mill is $50. Note that this $50 is the marginal control
cost of treating (cleaning) the one hundred and thirtieth unit of waste
(200–70).
Thus , given this situation, the paper mill will clearly have an incentive to
offer a financial bribe to the fish hatchery for the right to use the river for
discharging its industrial waste. For example, as shown in Figure 11.2, to
discharge the seventieth uni t of waste the paper mill will be willing to pay
the hatchery a fee of between $20 and $50. This should be acceptable to
both parties. For the hatchery, a payment exceeding $20 more than
compensates for the damage caused to its fish operation from the dump ing
of the seventieth unit of waste into the river. Similarly, this situation
should also be advantageous to the paper mill because the cost of using an
alternative technology to dispose of the seventieth unit (i.e., to clean up
the one hundred and thirtie th unit) of waste to this firm is at least $50. In
general, then, these two firms will be in a position to engage in a mutually
beneficial transaction provided that, at the point where the negotiation is
taking place, MCC>MDC. Furthermore, the negotiation between these
two parties ceases when, for the last unit of waste discharged by the paper
mill, MCC=MDC. This is indeed the condition for the optimal level of
pollution. In Figure 11.2, this is attained at We, or 110 units of emission.
As discussed earlier , the Coase theorem goes beyond the mere recognition
of optimality. It also states that this optimal outcome is completely
independent of the two parties who have rights to the river. To
demonstrate this, let us now consider the case where the paper mill h as
exclusive legal rights to the use of the river. Under these circumstances the
paper mill, if it wishes, can dispose of all its waste into the river. If this
strategy is followed, then as shown in Figure 11.2, the paper mill will
discharge a total of 200 units of waste into the river. However, this
company is not limited to this option only. As shown in Figure 11.2, for
each unit of waste discharged between 110 and 200 units, the MDC is munotes.in

Page 52

Environmental Economics
52 greater than the MCC. This situation will allow the fish hatchery and the
paper mill to engage in a mutually beneficial transaction.
To see this, let us focus on what happens when the emission is at 140
units. When this unit of waste is discharged, the MDC to the fish hatchery
is $45, but the cost to the paper mill of trea ting this same unit is $15. Note
that the $15 is the marginal cost to the paper mill for controlling the
sixtieth unit of emission (200 –140). Thus, when the emission level is at
140 units the MDC is greater than the MCC. Given this, the hatchery will
have an incentive to offer a financial bribe to the paper mill of anywhere
between $15 and $45 to withhold this unit of waste. It is easy to see that
the paper mill will most likely take this offerseriously since the cost of
controlling the sixtieth unit of was te (200 –140) is only $15. Thus, to the
extent that the offer of the hatchery exceeds $15, the paper mill will abide
by the wishes of the hatchery. A similar situation prevails for all the units
where the MDC exceeds the MCC —that is, between 200 and 110 uni ts.
Thus, the optimal level of pollution is again reached at We or 110 units,
where MDC=MCC. This result verifies the validity of the Coase theorem.
In the 1960s, for most economists the Coase theorem was an exciting and
appealing revelation. The profound implication of this theorem has been
that pollution problems can be resolved by an arbitrary assignment of
property rights. What is appealing about this is that it reduces the role of
public regulators to a mere assignment of enforceable ownership rights.
Once this is done, as discussed above, the optimal level of pollution is
attained through voluntary negotiation of private parties —which is
consistent with the spirit of the private market.
Despite its appeal, however, the Coasian approach has several weak nesses.
1. In our example above, the source of the pollution as well as the parties
involved in the dispute are easily identifiable. However, in many realworld
situations, the sources of the pollution are likely to be multifaceted and their
impacts quite di ffuse. In addition, environmental disputes normally involve
several parties. In a typical real -world situation, then, the cost of negotiation
and enforcement —the transaction cost —could be quite high. As discussed
earlier, a high transaction cost could dist ort the final outcome of an
environmental dispute in a rather significant manner. In such a situation, a
resolution reached using the property rights approach might be far removed
from what is considered to be socially optimal.
2. A property rights approach, especially its Coasian variation, seems to support
the ethos that “the end justifies the means.” As is evident from the above
discussion, in this approach the focus is singularly placed on attaining an
optimal outcome. Whether the optimal outcome is attain ed by assigning
property rights to the polluters or assigning them to the pollutees is
considered entirely irrelevant. Clearly, this seems to counter what appears to
be the conventional wisdom —the “polluter -pays principle.”
3. According to the Coase theorem, the optimal level of pollution can be
achieved irrespective of which party was given the initial property rights: —
the polluters or pollutees. However, what the theorem does not address is the
impact the initial assignment of property rights has on income distribution. In munotes.in

Page 53

Micro Foundations of
Environmental Economics -II
53 general, the income position of the party empowered with property rights is
positively impacted.
4. In the above analysis it is assumed that shifting the property rights from one
party to another would not cause either party to cease to funct ion. What if
this is not the case? What if giving the property rights to the hatchery makes
the paper mill go out of business or vice versa?
So far we have examined two possible mechanisms by which a society
could attempt to control pollution, namely liability laws and property
rights regimes. In both of these types of pollution control schemes, the
regulatory roles of public authorities were viewed as something to be
minimized. In the case of liability laws, the principal role of the court is
reduced to simply setting the fine (compensation) polluters have to pay to
the damaged parties. Under the property rights approach the sole
responsibility of the public authorities is to assign propert y rights to one of
the parties involved in an environmental dispute. Once these are done, at
least theoretically it is presumed that the interaction of the relevant parties
involved in the dispute will lead to an efficient outcome. In this sense,
then, it would be fair to say that the proponents of both liability laws and
property rights are advocates for a decentralized approach to pollution
control.
While this may be appealing in some professional circles, especially
among economists, the fact remains tha t the above two approaches are of
limited use in a real -world situation. This is because modern
environmental problems are generally widespread in their scope and
involve a large number of people with varying socioeconomic
circumstances. For this reason, a s public awareness of environmental
problems has increased, at least until recently one of the most popular and
appealing methods for reducing environmental damages has been direct
regulation —a centralized form of pollution control. Let us now discuss
and evaluate pollution control instruments that fall into the categories most
often labeled the “command -and control” approach.
4.7 SUMMARY
 The intersection of the two marginal abatement costs is where economic
efficiency is achieved. This is known as the "equ imarginal principle."
 Economic efficiency implies an economic state in which every resource is
optimally allocated to serve each individual or entity in the best way while
minimizing waste and inefficiency.
 When an economy is economically efficient, any ch anges made to assist one
entity would harm another. In terms of production, goods are produced at
their lowest possible cost, as are the variable inputs of production.
 The total monetary value of all the various damages resulting from the
discharge of untr eated waste into the environment is referred to as pollution
damage cost. munotes.in

54  Pollution control (abatement) costs represent direct monetary expenditures
by a society for the purpose of procuring resources to improve environmental
quality or to control pollutio n.
 In the case of environmental pollution, the Coasian approach suggests that
the optimal level of pollution can be achieved by an arbitrary assignment of
property rights to either the polluter(s) or the pollutee(s). This proposition
that the assignment of property rights to a specific party has no effect on the
optimal level of pollution is the core concept of what is widely known as the
Coase theorem.

5.1 INTRODUCTION
These days, environmental degradation is a great concerned for every
nation in the world. Subsequently, many measures have been taken up in
society level to improve the quality of the environment or to reduce
environmental degradation. As society developed, man’s impact on
environment grew in scope and strength. Nature has been increasingly
damaged, restorative capabilities have progressively weakened and human
environment is decaying day by day. Measures are now taken to prevent
this envir onmental degradation. munotes.in

56 5.2 VALUATION OF NATURALRESOURCES: DIRECT
AND INDIRECT METHODS ENVIRONMENTAL
IMPACT ASSESSMENT
Natural resource valuation has always had a fundamental role in the
practice of cost -benefit analysis of health, safety, and environmental
issues. Today, this role is becoming all the more apparent in the conduct
of natural resource damage assessments (NRDA) and cost -benefit analyses
of environmental restoration (ER) and waste management (WM)
activities. As such, environmental professionals are more interested in
how natural resource values are affected by ER and WM activities.
Monetary valuation of environmental goods has become very important
and the aim of such valuation is usually to incorporate environmental
concerns into a cost -benefit analysis.
Valuation can simply be defined ‘as an attempt to put monetary values to
environmental gooda and services or natural resources. It is a key exercise
in economic analysis and its results provide important information about
values of environmental goods and services. This information can be used
to influence decisions about wise use and conservation of these resources.
Valuation refers to the process of assigning economic values to
environmental/natural resources. It is a way to understand how much
something is worth to particular people or to the society as a whole.
Economic valuation is done on the basis of economic theory estimating
Consumer’s and producer’s surplus using market price and quantity data
regarding the environmental goods and servic es traded in the market.
The economic method considers Total Economic Value which considers
the use value as well as non -use value of environmental goods and
services. The use value refers to the tangible features of commodity which
satisfies some human r equirement for which people are ready to make
some payment. Whereas non -use value is the value that people assign to
environmental goods and services, even if they may never use it.
The use value (an observable interaction between the individual and the
environment) is further divided into following parts such as
 Direct/Actual Use Value which is obtained through those removable
products in nature which directly satisfy human wants through their
consumption or those which have direct consumptive uses. Such use
can be for commercial purpose (profit motive) or non -commercial
purpose (without profit).
 Indirect Use value is obtained through a non-removable product in
nature which indirectly satisfy human wants without their consumption
or which have non -consumptive uses. Non -use value does not involve
actual interaction between people and the environment.
 Option Value is the price that the indi viduals are willing to pay for
conservation of an element in view of its possible use in the future. It munotes.in

Page 57

Tools and Environmental Issues - I
57 is not related to current use and is used to measure the value attached
to future use. Option value is related to potential, but uncertain, future
resou rce uses -either direct or indirect or either commercial or non -
commercial. It is defined as the willingness to pay by the potential user
for the possible use of natural environment in future.
The non -use value is also known as non -user or passive value. It is the
value assigned for existence of the natural resources. It is further divided
into the following parts
 Bequest value is the value placed for maintaining or preserving a
natural asset or resource, that has no use now, so that it is available for
future generations. This value is placed on a resource that will never
be used by current individuals and thus, it derives the value from
satisfaction of preserving a natural environment or a historic
environment (natural/cultural heritage) for future generati on. It refers
to an individual willingness to pay to preserved resource for future
generation.
 Existence Value is derived from the knowledge of people about the
existence of natural resources. It reflects the benefit that people receive
from knowing that a particular environmental resource is existing, for
example the knowledge of endangered species.It refers that the value
which is individual is willing to pay for an environmental amenity
even though individual received no direct benefit.
 Altru istic Value means ‘selfless’ or ‘unselfish’, it is the value assigned
to the environment resources for unselfish reasons like people may
want natural resources to be there for the benefit of other people
during their life -time.Altruistic Value is related with the advantages,
benefits and the satisfaction which people derive from their knowledge
which explains that there is an existence of environmental assets for
the pleasure of other people living in present times. It represents the
value of sc enic beauty even though no market transaction may occur to
capture that value
Though these methods are used for valuation yet they suffer from several
problems or limitations such as
 It has a very limited coverage. It is so because very few environmental
goods and services are bought and sold in the market.
 There is a problem of market imperfections. It distorts prices and thus
the efficacy of such prices in measuring the net benefit of
environmental resource is inappropriate.
 Another problem is that we als o get the seasonal and cyclical
variations in prices.
 The scope or limit of market economy also depends on the level of
development of an economy. In underdeveloped countries, many
resources that contribute to the production are not brought to the
market and thus they go unaccounted . Thus, they are not reflected in
the prices. munotes.in

Environmental Economics
58 5.3 THE METHODS OF ENVIRONMENTAL
VALUATION ARE BROADLY DIVIDED INTO
TWO CATEGORIES VIZ.
I. Market Based Methods
II. Non-Market Based Methods
I. Market Based Methods: This method uses the market price of
environmental goods and services which are bought and sold in the market
place. It is based on the Cost -Benefit analysis.
1. Market Value Based on Valuation Approach depends on the market
price and quantity to derive total value. It depends on the value of
environmental goods and services based on the market price and the
available quantity of these goods and services. In this we get
A. Observed Market Value Approach : Demand for natural resources is
measured on the assumption that many factors that might influence
demand, such as personal income, the prices of related goods and services,
and individual tastes and preferences, remain unchanged during the study
period. Under these assumptions, the estimated demand curve is a
systematic measure of how people value the resource. To illustrate, Figure
1 shows that 20,000 acres of land were sold at a market price of $1500 per
acre. In the course of these land transactions, $ 30.0 million exchanged
hands in the land market, i.e., 20,000 x $1500. Had land become
increasingly scarce, this scarcity would ultimately be reflected in higher
land prices. It is the most straight forward method.
B. Related Goods Approach: It is related to determine the value of non -
marketed goods. It includes
 Barter Exchange Approach: Here we take note of gods and services
exchanged for goods and services. some of the forest products such as
wild fruits and vegetables are not sold in formal markets. Some of
these goods, however, may be exchanged on anon -commercial basis
for goods which are available in the market. The unit of exchange
between the two can be used to valuation of the forest product. For
example, leafy vegetables are collected from forest by villagers
residing in fringe areas, which are used for self -consumption. Since
these vegetables are not marketed it is not possible to find out their
market prices. However, if these vegetables are regularly exchanged
for some other commodity, say paddy, then the unit of exchange
between leafy vegetable and paddy can be found out. The market price
of paddy in this case could be used to find the value of the l eafy
vegetables under consideration.
 Direct Substitute Approach: In this case the value of a similar good
is used for valuation of the natural resource. For example, the value of
he1 wood collected by villagers fiom the nearby forests. Here a close
substit ute would be firel wood bought fiom the market or even the munotes.in

Page 59

Supplementary Analytical
Tools and Environmental Issues - I
59 value of kerosene or charcoal equivalent to the fuel wood collected.
The accuracy of this method depends upon the extent to which the
natural resource and the marketed product used as substitute ar e
similar.
 Indirect Substitute Appmach : In many cases it is difficult to find a
direct substitute. which enters into formal market, for the
environmental function to be evaluated. In such cases we combine the
production function approach with the direct s ubstitute approach. First,
we find a direct substitute of the environmental function. Second, we
find out the value of this direct substitute through the production
function approach discussed earlier. Thus we find out the value of the
environmental functi on indirectly through the production function
approach. The indirect substitute approach is based on stringent
assumptions about the substitutability between the two goods, the role
of the substitute good as an input in the production of the output, and
the value of the output.
2. Benefit Based approach deals with the benefits derived from the
economic activities. It takes note of the
A. Productivity Approach: It is a common economic technique. It
relates output to different levels of inputs i.e. say different f actors of
production like land, labour, capital, raw material etc. It makes use of
the market price.
B. Change in Income or Human Capital or Foreign Exchange
Approach : It is estimated on the basis of changes in income either due
to degradation or improvement in environment. Degradation of
environment creates several health hazards and people fall sick. There
are several monetary damages due to loss of work, ill health disability
caused by environmental degradation. The damages are in the form of
foregone earni ngs due to untimely death, sickness, absenteeism etc.
,increased medical expenditure and physical cost.The human capital
approach values environmental attributes through their effects on the
quantity and quality of labour. The loss earnings approach focuse s on
the impact which adverse environmental conditions have on human
health and the resultant costs to society in terms of income lost through
illness, accidents and spending on medical treatments. But at the same
time in the healthy environment there will be an improvement in
health, postponed illness, fewer deathsetc.
3. Cost based Valuation Approach uses following techniques:
A. Opportunity Cost Approach: This method values the benefits of
environmental protection in terms of what is being foregone to achiev e
it. This forms the basis of compensation payments for the compulsory
purchase by the government of land and property under eminent
domain laws. The opportunity cost method is useful in cases where it
is difficult to enumerate the benefits of an environme ntal change. For
example, rather than comparing the benefits of various alternative
conservation schemes in order to choose between them, the method munotes.in

Page 60

Environmental Economics
60 can be used to enumerate the opportunity costs of foregone
development associated with each scheme with the preferred option,
being the one with the lowest opportunity cost.
This method is used when individual labour is involved in harvesting
or collecting the natural resource. A basic assumption is that capital
requirement for such a job is minimal. For exampl e, for gathering &el
wood in forests individuals need to spend time and do not need much
capital. The opportunity cost of such time spent could be considered as
the value of the environmental resource under consideration

B. Replacement Cost Method: The replac ement/restoration cost
technique can be used to measure the costs incurred in restoring or
replacing productive assets or restoring the natural environment or
human health as a result of the impacts of environmental degradation.
As with preventative expen diture, restoration costs is a relatively
simple technique. The resource replacement cost method determines
damages for natural resources based on the cost to restore, rehabilitate,
or replace the resource or resource services without injury to the level
of the resource stock or service flow. This is a Cost -based technique
that measures the potential expenditures that would be required to
replace or restore a productive asset that would be damaged by some
project or development. These costs are then compare d to the costs of
preventing the damage from occurring to determine which is more
efficient. A shadow project is usually designed specifically to offset
the environmental damage caused by another project. For example, if
the original project was a dam that inundated some forest land, then
the shadow project might involve the replanting of an equivalent area
of forest elsewhere. It values an environment good by the cost incurred
in restoring the environment to its original state of level after it has
damaged . In the following diagram the benefits and costs per unit are
measured on the vertical axis while the level of restoration is at the
horizontal axis. The restoration level means to replace the lost
environmental good. The slope of curve В indicates that w ith the
increase in restoration level, benefits increase at a decreasing rate.


Figure : 5.1
munotes.in

61 The slope of curve С indicates that the re storation costs are an increasing
function of the level of restoration. The economic efficiency is achieved at
the restoration level OR E where the difference between curve В and curve
С is the maximum. The net gain is NG at this level of restoration.

C. Reloc ation/Restoration Cost Method: This is a cost -based technique
used to estimate the monetary value of environmental damages based
on the potential costs of relocating a physical facility that would be
damaged by a change in environmental quality. This metho d relies on
data on potential expenditures. This method is applicable in situations
where natural environment in a particular area is put to some
alternative use. For example, the cost of establishing a new protected
forest area. In this method, the flow o f ecological functions is
maintained as in restoration cost and replacement cost techniques. The
difference, however, is that instead of recreating ecological functions
in the vicinity, the inhabitants are moved to a different locality.The
restoration cost technique takes into account the cost of recreating the
ecosystem. For example, degradation of forests results in a reduced
flow of forest products and other functions. In order to restore the flow
government intervention (in terms of policy implementatio n and
afforestation) is required. According to the restoration cost method, the
value of forest functions is its restoration or recreation cost.
D. Preventive Expenditure: In this method the value of environmental
benefit is taken to be the cost of mitigating the adverse impact of
environmental degradation. We can cite several examples to explain
the method: Farmers often increase the use of inputs (fertilizer,
pesticides, seed, etc.) to neutralize the effect of falling land
productivity. In order to avoid cou gh, breathlessness or irritation in the
eye residents in an industrial area may take regular medicines. The
expenditure on such counts can be added to obtain the total preventive
cost, which will provide an estimate of the value of environment. It is
also called as ‘Exclusion facilities’, ‘Defensive Expenditures’ or
‘Mitigation Expenditure’.
II. Non-Market Based Methods: The market price does not correctly
measure the economic value of goods and services. Many a times many
people are actually willing to pay mor e price for the goods than the market
price. Thus, their value exceeds the market price. Non -market value tries
to find the value of those environmental goods and services which do not
enter into market or for which there is no market existing.
A. Expressed/ Stated Preference Methods: The demand for
environmental goods can be measured by examining individuals’
expressed/stated preference for these goods relative to their demand
for other goods and services. These techniques avoid the need to find a
complementa ry good (travel or house), or a substitute good
(compensating wage rate), to derive a demand curve and hence
estimate how much an individual implicitly values an environmental
good. Moreover, expressed preference techniques ask individuals
explicitly how m uch they value an environmental good. munotes.in

62 Contingent Valuation Method (CVM):
Analytic survey techniques rely on hypothetical situations to place a
monetary value on goods or services. Most survey -based techniques are
examples of contingent valuation method. Contingent valuation frequently
elicits information on willingness to pay or willingness to accept
compensation for an increase or decrease in some usually non -marketed
goods or services. This method puts direct questions to individuals to
determin e how much they might be willing to pay for environmental
resources or how much compensation they would be willing to accept if
they were deprived of the same resources. This method is more effective
when the respondents are familiar with the environmental good or service
and have adequate information on which to base their preferences.

(1) Trade -Off Game Method:
This method relates to a set of contingent valuation techniques that rely on
the creation of a hypothetical market for some good or service. In a single
bid game the respondents are asked to give a single bid equal to their
willingness to pay or willingness to accept compensation for the
environmental good or service described. In an iterative (repeating) bid
game the respondents are given a variet y of bids to determine at what
price they are indifferent between receiving (or paying) the bid or
receiving (or losing) the environmental good at issue.

The trade -off game method is a variant of the bidding game wherein
respondents are asked to choose bet ween two different bundles of goods.
Each bundle might, for example, include a different sum of money plus
varying levels of an environmental resource. The choice indicates a
person’s willingness to trade money for an increased level of an
environmental go od. When no money is involved, the approach becomes
similar to the costless -choice method.

(2) Costless -Choice Method:
The costless -choice method is a contingent valuation technique whereby
people are asked to choose between several hypothetical bundles of goods
to determine their implicit valuation of an environmental good or service.
Since no monetary figures are involved, this approach may be more useful
in settings where barter and subsistence production are common.

(3) Delphi Method:
The Delphi method is a variant of the survey -based techniques wherein
experts, rather than consumers, are interviewed. These experts place
values on a good or service through an iterative process with feedback
among the group between each iteration. This expert -base approac h may
be useful when valuing very esoteric resources.

This is really a specialized survey technique designed to overcome the
speculative and isolated nature of expert opinions. A sufficiently large
sample of experts is presented individually with a list of events on which
to attach probabilities and to which other events, with probabilities may be
added. Some recent Delphi exercises have been recreation -specific. But munotes.in

63 testing the accuracy of their forecasts is not yet possible, especially since
the predictio ns are only meant to be general perspectives.

B. Revealed Preference Method: The demand for environmental goods
can be revealed by examining the purchases of related goods in the
private market place. There may be complementary goods or other
factor inputs in the household’s production function.
(1)Travel Cost Method: The travel -cost method is a widely used
surrogat e market approach that relies on information on time and travel
costs to derive a demand curve for a recreational site. This curve is in turn
used to estimate the consumers’ surplus or value of the site to all users.
This approach is widely used to value t he recreational benefits of public
parks and other natural areas.

This method seeks to determine the demand for a recreational site (i.e.
number of visits per year to a park) as a function of variables like price,
visitors’ income, and socio -economic chara cteristics. The price is usually
the sum of entry fees to the site, cost of travel, and opportunity cost of
time spent. The consumers’ surplus associated with the demand curve
provides an estimate of the value of the recreational site in question.

The most common forecasting technique for a specific site is the Clawson -
Knetsch -Hotelling method. It is a technique commonly associated with
benefit estimation in recreation cost -benefit analysis. This method uses
information on travel costs to generate a final demand curve for a
recreation outlet. Hence it is most appropriate for those outlets where
travel cost is a major component of total visit costs typically to free
countryside outlets.

According to Clawson and Knetsch, outdoor recreation activities satisfy
individual needs, such as physical, social or psychological. It is
necessarily a kind of package deal involving anticipation, travel to the site,
the activity itself, the return travel and finally recollection.

The travel -cost method is explained in the fo llowing Figure. Suppose
there is a single lake in a city, where the entry fee is OP which is fixed per
visit. Initially, recreational demand for the lake is shown by the demand
curve BD o and the environmental quantity level is E 0.

Figure : 5.2 munotes.in

Page 64

Environmental Economics
64 If there is an improvement in environmental quality of lake, then the
demand curve will shift outward as AD 1 and environmental quality level
to E 1. With this eff ect, there is an increase in the number of visits to PK.
The gain in consumers’ surplus is equal to the area PAK. The net gain in
consumers’ surplus after improvement in environmental quality of the lake
is shown as: РАК – PBC = ABCK.

The travel -cost appro ach looks at the pattern of recreational use of a lake
and uses this information to derive a demand curve to estimate the total
amount of consumers’ surplus. To do this, visitors are divided into a
number of origin zones of increasing distance from the lak e. Then a
survey is used to determine the time and monetary cost involved in
reaching to the lake.

Its Criticism:
 This approach is most successful where there is wide variation in the
travel cost of various users and where recreation at the site in questio n
will be the primary objective of visits. But wide variations in tastes
and preferences and substitute availability at different distances from
the site, distort demand estimates.
 The travel -cost method is of limited value if congestion is a problem.
Smal l changes affecting recreational quality may be difficult to
evaluate using this method.
 The basic assumption of travel -cost method is that consumers treat
increase in admission fees as equivalent to increase in travel cost. This
is subject to question.
 Another problem associated with this method is that it assumes
recreational quality remains constant over the range from zero use to
full present use at the going admission fee. This is highly hypothetical.
 Bateman is of the view that the travel -cost method measures only the
use value of recreation sites. Underestimation of site value due to the
truncation of non -visitors would be made worse if the non -use value of
both visitors and non -visitors were relevant. This method is not
capable of producing any tota l economic value estimate in that it
cannot estimate non -use items such as existence value.
(2) Hedonic Price Method: The underlying assumption of the hedonic
price method is that the price of a property is related to the stream of
benefits to be derived f rom it. The method relies on the hypothesis that the
prices which individuals pay for commodities reflect both environmental
and non -environmental characteristics. The implicit prices are sometimes
referred to as hedonic prices, which relate the environmen tal attributes of
the property.
Therefore, the hedonic price approach attempts to identify how much of a
property differential is due to a particular environmental difference
between properties, and how much people are willing to pay for an munotes.in

Page 65

65 improvement in the environmental quality that they face and what the
social value of improvement is.
The hedonic price method is based on consumers which postulates that
every good provides a bundle of characteristics or attributes. Again,
market goods can be regarded as intermediate inputs into the production of
the more basic attributes that individuals really demand.
The demand for goods, say housing can, therefore, be considered as a
derived demand. For example, a house yields shelter, but through its
location it also yields access to different quantities and qualities of public
services, such as schools, centres of employment and cultural activities
etc. Further it accesses different quantities and qualities of environmental
goods, such as open space parks, lakes etc.
The price of a house is determined by a number of factors like structural
characteristics, e.g. number of rooms, garages, plot sizes etc. and the
environmental characteristics of the area. Controlling the non -
governmental characteristics which affect the demand for housing, permits
the implicit price that individuals are willing to pay to consume the
environmental characteristics associated with the house to be estimated.
The hedonic price function describing the house price Pi of any housing
unit is given below:
Pi = f [S 1i…………S ki, N1i,…………….N mi, Z1i………….Z ni]
Where, S represents structural characteristics of the house ii.e. type of
construction, house size and number of rooms; N represents
neighbourhood characteristics of house i, that is accessibility to work,
crime rate, quality of schools etc. It is assumed that only one environment
variable affects the property value i.e. air quality (Z).
For example, if the linear relation exists, then the equation becomes
Pi = [α 0 + α 1S1i + ….. + α KSKi + β 1N1i + ……. + βmNmi + γaZa]
and y a > 0.
There is a positive relation between air quality and property price as
shown in the following figure. The figure indicates that house price
increases with air quality improvement. munotes.in

Page 66

Environmental Economics

Figure :5.3
Following figure indicates that the implicit marginal purchase price of
Za (air quality) varies according to the ambient level (Z a) prior to the
marginal change.

Figur e 5.4
The hedonic price method has become a well -established technique for
estimating the disaggregated benefits of various goods attributes. In the
case of housing, these attributes include not only basic structural and
amenity characteristics but also en vironmental characteristics such as
clean air, landscape and local ecological diversity. Thus, when a particular
policy is implemented which will have a very great effect on the local
environment, the hedonic method offers a useful way of estimating the
change in amenity benefits.
Its Criticism:
 This method is of no relevance when dealing with many types of
public goods i.e. defence, nation -wise air pollution and endangered
species, etc., as it prices are available for them.
 The hedonic price method may be used to estimate the environmental
benefits provided to local residents by an area as it exists today. But in
fact, it cannot reliably predict the benefits which will be generated by munotes.in

Page 67

67 future improvements because those improvements will have the effect
of shifting the existing function.
 Another problem is whether an individual’s perceptions and
consequent property purchase decisions are based upon actual or
historic levels of pollution and environmental quality. If expectations
are not the same as measured b y present pollution estimate, then there
are clearly problems relating to values derived from purchases.
 Moreover, expectations regarding future environmental quality may
bias present purchases away from that level dictated by present
characteristic levels .
 This method has been criticised for making the implicit assumption
that households continually re -evaluate their choice of location.
 Further, there is considerable doubt that such an assumption can hold
in the context of spatially large study areas. If people cluster for social
or transportation reasons, the results of this method will be biased.
(3)The Preventive Expenditure Method: The preventive expenditure
method is a cost -based valuation method that uses data on actual
expendi tures made to alleviate all environmental problems. Often, costs
may be incurred to mitigate the damage caused by an adverse
environmental impact. For example, if drinking water is polluted, extra
purification may be needed. Then, such additional defensive or preventive
expenditure could be taken as a minimum estimate of the mitigation of
benefits beforehand.
In the preventive expenditure method, the value of the environment is
inferred from what people are prepared to spend to prevent its degradation.
The averting or mitigating behaviour method infers a monetary value for
an environmental externality by observing the costs people are prepared to
incur in order to avoid any negative effects.
For example, by moving to an area with less air pollution at a grea ter
distance from their place of work thus incurring additional transportation
costs in terms of time and money. Both of these methods are again,
conceptually closely linked.
These methods assess the value of non -marketed commodities such as
cleaner air an d water, through the amount individuals are willing to pay
for market goods and services to mitigate an environmental externality, or
to prevent a utility loss from environmental degradation, or to change their
behaviour to acquire greater environmental qu ality.
(4) Surrogate (or Substitute) Markets : When no market exists for a
good or service and therefore, no market price is observed, then surrogate
(or substitute) markets can be used to derive information on values. For
example, travel -cost information c an be used to estimate value for visits to
a recreational area; property value data are used to estimate values for munotes.in

Page 68

Environmental Economics
68 non-marketed environmental attributes such as view, location or noise
levels.
The effects of environmental damages on other markets like pro perty
values and wages of workers are also evaluated. Valuation in the case of
property is based on risks involved in evaluating the value of property due
to environmental damage. Similarly, jobs with high environmental risks
will have high wages which wil l include large risk premiums.
(5) Property -Value Method : In the property -value method, a surrogate
market approach is used to place monetary values on different levels of
environmental quality. The approach uses data on market prices for homes
and other real estates to estimate consumers’ willingness to pay for
improved levels of environmental quality, air, noise etc.
In areas where relatively competitive markets exist for land, it is possible
to decompose re al estate prices into components attributable to different
characteristics like house, lot size and water quality. The marginal
willingness to pay for improved local environmental quality is reflected in
the increased price of housing in cleaner neighbourh oods.
(6) The wage -differential Approach : The wage -differential approach is a
surrogate market approach that uses information on differences in wage
rate for similar jobs in different areas to estimate monetary values for
different levels of environmental q uality. This approach has been used to
estimate values for such environmental variables as different levels of
congestion, air pollution and aesthetics.
Wages also vary in response to various factors such as education and
training, natural dexterity, exper ience, demand and supply in each labour
market area, occupational risks to health, probability of death, and
associated living conditions including environmental ambience etc.
The hedonic wage approach has also been used in the wage -risk analysis
to determ ine the value of life and limb in relation to the hazards faced at
work. The general hedonic wage equation can be expressed as
P = P (J, R, S)
Where, P is the payment rate for a given job, У is a vector of another job -
related attributes e.g. working hours , holiday, sickness benefits etc., R is
the risk of death and S is a vector of skills required to do the job. The
hedonic wage approach has traditionally been used to measure
employment attributes, principally risk of death or injury in particular
labour m arkets. However, by observing variations in wage levels over
space, and netting out the influence of other attributes, they have also been
used to value the quality of life over large areas such as countries or
continents.

69 5.4 LIFE CYCLE ANALYSIS:
Life Cyc le Analysis (LCA) had its beginnings in the 1960s. Concerns over
the limitations of raw materials and energy resources sparked interest in
finding ways to cumulatively account for energy use and to project future
resource supplies and use. In one of the fi rst publications of its kind,
Harold Smith reported his calculation of cumulative energy requirements
for the production of chemical intermediates and products at the World
Energy Conference in 1963.
Later in the 1960s, global modeling studies published in The Limits to
Growth (Meadows et al., 1972) and A Blueprint for Survival (Goldsmith et
al., 1972) resulted in predictions of the effects of the world’s changing
populations on the demand for finite raw materials and energy resources.
The predictions for r apid depletion of fossil fuels and climatological
changes resulting from excess waste heat stimulated more detailed
calculations of energy use and output in industrial processes. During this
period, about a dozen studies were performed to estimate costs an d
environmental implications of alternative sources of energy.
In 1969, researchers initiated an internal study for The Coca -Cola
Company that laid the foundation for the current methods of life cycle
inventory analysis in the United States. In a compariso n of different
beverage containers to determine which container had the lowest releases
to the environment and least affected the supply of natural resources, this
study quantified the raw materials and fuels used and the environmental
loadings from the ma nufacturing processes for each container.
Life Cycle Analysisor Life Cycle Assessment (LCA) is a method used to
evaluate the environmental impact of a product through its life cycle
encompassing extraction and processing of the raw materials,
manufacturing , distribution, use, recycling, and final disposal.
Life cycle analysis is the act of measuring the environmental impact of a
product or service throughout its life cycle, from the resources used to
create the product or service, across its use by the user , to it's final end of
life destination. An LCA measures the environmental impacts of each
distinct part involved in creating and using products and services, such as
energy used in production, fuel used in transport, and end -of-life
ecological costs. This helps us compare between products, materials, and
methods used, providing useful information by which to make decisions
that could help the environment .
Life cycle analysis (LCA) is a method of quantifying the environmental
impacts associated with a give n product. In LCA, researchers create an
inventory of resources used and pollutants generated in product production
and use. From this an impact assessment estimates the product's ultimate
effects on human health, ecosystem function, and natural resource
depletion. munotes.in

Page 70

Environmental Economics
70 Life cycle assessment (LCA) is the factual analysis of a product’s entire
life cycle in terms of sustainability. Every part of a product’s life cycle –
extraction of materials from the environment, the production of the
product, the use phase and what happens to the product after it is no longer
used – can have an impact on the environment in many ways. With LCA,
you can evaluate the environmental impact s of your product or service
from the very first to the very last or from cradle to grave.

Ultimately, an LCA is interested in what we have to take from the
environment, in terms of raw materials and energy, and what impact the
product then has on the environment during its use (or the service, or the
material). It’s called “life cycle” because it usually takes the entire
existence of the product into account: from the raw ma terial stage of
putting the product together, through the use phase where the service,
material or product serves its’ purpose, to the “end -of-life” stage where the
product is broken down in whatever fashion occurs.
The stated purpose of an LCA is to find the environmental impacts of a
product, service or material, typically so some decision can be made in the
design of that item or in the formulation of some policy. It might be that
different alternative ways of creating a product or providing a service a re
being compared to see which has a lower environmental impact. The
application of LCA helps to promote the sustainable design and redesign
of products and processes, leading to reduced overall environmental
impacts and the reduced use and release of non -renewable or toxic
materials.
An LCA can be used by different people for different things. But it’s all
about environmental impact and performance.
Design : what changes can we make to the product to lessen its
environmental impact?
Purchasing : which produc t has the least environmental impact?
Marketing : is this product “greener” than a competitor?
Benchmarking : how’s our company doing next to all the others in our
industry?
Tracking : how’s our environmental performance doing this year
compared with last yea rs? munotes.in

71 Policy : what initiatives will help improve overall environmental
outcomes?
5.4.1.Four steps of life cycle assessment
LCA is a standardized methodology, which gives it its reliability and
transparency. The standards are provided by the International Organisation
for Standardisation (ISO) in ISO 14040 and 14044, and describe the four
main phases of an LCA:
1. Goal and scope definition
2. Inventory analysis
3. Impact as sessment
4. Interpretation
1. Goal and scope definition: The goal & scope definition step
ensures that your LCA is performed consistently. An LCA models a
product, service, or system life cycle. A model is a simplification of a
complex reality and as with all si mplifications, this means that the reality
will be distorted in some way. The challenge for an LCA practitioner is to
make sure the simplification and distortions do not influence the results
too much. The best way to do this is to carefully define the goa l and scope
of the LCA study.
The goal and scope describe the most important choices, which are often
subjective. For instance, the reason for executing the LCA, a precise
definition of the product and its life cycle and a description of the system
boundar ies.

What are we looking at? The point at which all decisions are made about
what to include in the study, why it’ s being carried out, the “functional
unit” that is being focused on, the different systems that need to be
investigated, as well as the boundaries – it’s often not practical (or
possible) to measure every single input and output and in the cases where
there is good reason to think they are small or where they are deemed to
be beyond the scope of what you are interested in, they are left out. Every
LCA has boundaries.

Another task at this point involves “screening”, which is the preliminary
execution of the LCA and any adjustment in the plan.

Thus.this step includes the objectives of the study, the functional unit, the
system boundaries, the data needed, the assumptions, and the limits that
must be defined. Particularly, the functional unit is the reference unit used
to normalize all the inputs and outputs in order to compare them with each
other.

2. Inventory: Inventory analysis of extractions and emissions. This
step refers to the analysis of the material and energy flows and the study of munotes.in

Page 72

Environmental Economics
72 the working system. On the other hand the data collection for the entire
life cycle implies the modelization of the analyzed system. Moreover, one
of the most critical aspects of this phase is the quality of inputs, which
must be verified and validated in order to guarantee t he data reliability and
correct use. During this stage, a conversion of the available data to
appropriate indicators takes place. The indicators are given per functional
unit used. In the inventory analysis, you look at all the environmental
inputs and out puts associated with a product or service. An example of
an environmental input – something you take out of the environment to
put into the product’s life cycle – is the use of raw materials and energy.
Environmental outputs – which your product’s life cy cle puts out into the
environment – include the emission of pollutants and the waste streams.
Together, this gives you the complete picture.
Every LCA has an inventory. This is the data that you are collecting. The
inventory includes things like emissions, energy requirements and material
flows for each process involved. These are the flows into and out of the
system you are studying. The data of these are adjusted depending on the
functional unit you’re looking at.

This is known as a Life Cycle Inventory (LCI)
This can be extremely complex because it can involve dozens of separate
processes, as well as hundreds of tracked substances. This is where most
of the complexity of an LCA is involved.

3. Impact Assessment: Life cycle impact assessment (LCIA):This step
includes the assessment of the potential impacts associated with the
identified forms of resource use and environmental emissions. The impact
assessment methods, which are used in LCA can be divided into two
categories: those that focus on the amount of r esources used per unit of
product (upstream methods) and those which estimate the emissions of the
system (downstream methods). In the life cycle impact assessment
(LCIA), you draw the conclusions that allow you to make better business
decisions . You class ify the environmental impacts, evaluate them by what
is most important to your company, and translate them into environmental
themes such as global warming or human health.
The most important choice you have to make is how integrated you want
the results to be. Would you like a single score to show how sustainable
your product is? Or to be able to see whether your new design improves
on CO 2 emissions and keeps land use change at least the same? This
usually depends on how you would like to address your aud ience and the
ability of your audience to understand detailed results.

The Life Cycle Impact Assessment (LCIA) is where the impacts on the
environment are calculated. The categories of impacts are chosen and the
impacts on them based on the flow of emissio ns, energy and material from
the inventory, are assessed.
munotes.in

Page 73

Tools and Environmental Issues - I
73 There are lots of different types of impacts (depletion of abiotic resources,
global warming, ozone layer depletion, acidification, etc) so this stage
accounts for all the different impacts that ha ve been chosen.

4. Interpretation: In this phase the analyst aims to scrutinize the results
and discuss them, giving as much precise information as possible to the
decision makers. Moreover, this step may highlight some problems in the
LCA development which need a more detailed approach: for instance, it
can be decided to improve the quality level of some data collected from
the literature, because they describe a process which significantly
influences an environmental pressure and therefore a more elevated
accuracy of them may guarantee less variability in the results. This
mechanism of the LCA assures the improvement of results.During the
interpretation phase, you check that your conclusions are well -
substantiated. The ISO 14044 standard describes a number o f checks to
test whether conclusions are adequately supported by the data and by the
procedures you used. This way, you can share your results and
improvement decisions with the world without any surprises. Finally, the
results are analysed in the context of the goal and scope of the study set
out at the beginning. What have we learned about the system from this
LCA? This is where recommendations are typically included.
5.4.2 Life cycle assessment vs other methods
Life cycle studies can be performed for va rious scopes: cradle to gate (raw
materials until factory gate), gate to gate (only focusing on the
manufacturing processes) or cradle to grave (raw materials until disposal).
What makes it different from other models is mainly its data -driven
methodology. The two main other methods, cradle -to-cradle and the
circular economy, are designed to capture the hearts of audiences. LCA is
designed to capture the mind as well.
Cradle to cradle
The cradle -to-cradle certification system is about qualitative visions and
storytelling, using qualitative criteria to judge whether a product can be
certified. Criteria include material health, material reuse, renewable
energy and ca rbon management, water stewardship and social fairness.
The lowest score on these criteria becomes the product’s overall mark. In
contrast to LCA, cradle to cradle does not measure whether a certified
product actually has a lower overall environmental impa ct, so a cradle to
cradle -certified product may end up having a shifted or even increased
burden.
Circular economy
The circular economy is an inspirational strategy for creating value for the
economy, society and business while minimizing resource use and
environmental impacts through reducing, re -using and recycling. In
contrast, life cycle assessment is a robust and science -based tool to
measure the environmental impacts of products, services and business
models with a sort of accountancy approach. Combin e both the robustness munotes.in

economy and you have a holistic approach for innovation
5.4.3.Limitations of LCAs
As with every scientific method, there are always some limitations that we
should be aware of. In the case of LCAs, they do not detract from the
depth of understanding that is available only through the comprehensive
LCA route. These limitations include:
 Studies relate to normal operations, rather than where incidents occur,
which must be understood through separate risk assessments
 The quality of the available data: obviously this is what determines the
validity of the whole LCA
 Reliability of the environm ental scores is dependent on the skill of the
LCA practitioners employed
 Investment decisions are delayed as a consequence of how long LCAs
take

6.1 POLLUTION
The word pollution originates from the Latin word “Polluere” which
means “to soil or defile”. Pollution is the intro duction of containments into
the natural environment that cause adverse change. According to The
National Academy’s report review of US Water Management and Control
defines, “pollution as undesirable change in the physical, chemical and
biological characte ristics of air, water and land, that will be or may be
harmful to human and other life”. Pollution causes an undesirable change
in physical, chemical or biological characteristics of environment.
We come across different types of pollution. Let us study t he concepts of
Air, Water and Noise pollution.
(A) Air Pollution: Air pollution means presence of either undesirable
gases or the excess of any of the gases in more than normal proportion or
presence of both the above factors, in the atmosphere, as a result of which, munotes.in

Page 76

Environmental Economics
76 the natural quality of air is adversely affected, hence, it becomes unfit to
breathe. Several factors are responsible for air pollution
 Oxides of carbon: The combustion of fossil fuels to provide a source
of energy is the major means by wh ich man pollutes the atmosphere.
Carbon monoxide (CO), and carbon dioxide (CO2) are the gaseous
pollutants produced in largest quantities from natural and
anthropogenic sources. Consumption of transport fuels are the
principal source of Co and CO2.
 Oxides of Sulphur: Gaseous sulphur dioxide (SO2) and sulphur
trioxide (SO3) are serious pollutants of our atmosphere. Coal
combustion, oil refineries, copper, lead and zinc smelting are the
important sources of oxides of SO2 andSO3.
 Oxides of Nitrogen: Number of Oxides of Nitrogen exist in the
polluted atmosphere play a significant role in air pollution. The
principal sources of nitrogen oxides are combustion of coal, transport
and industrial processes.
 Industry: Industries are a major contributor to air pollutio n. Industrial
processes discharge pollutants such as nitrous oxide and hydro
fluorocarbons into the air. Petroleum refineries also liberate lots of
hydrocarbons into the air. Agricultural practices like livestock rearing
and landfills also add to atmospher ic methane concentrations. The
overall effect is amplification in the global warming probability.
 Vehicle Emissions: Vehicle emissions are another source of fossil fuel
emissions which invariably leads to air pollution. Cars, heavy duty
trucks, shipping vessels, trains, and airplanes all burn lots of fossil
fuels to work. Emissions from automobile engines hold both primary
and secondary pollutants. This is a major cause of pollutio n and one
that is very difficult to deal with as transportation is a major industry
in itself. Private transportation accounts for about 10 percent of an
individual’s carbon footprint, or the amount of carbon dioxide our
activities and lifestyle contribute to the atmosphere.
 Household and Farming Chemicals: Fumigating homes, crop
dusting, painting supplies, household cleaning products, over the
counter insect/pest killers, fertilizer dust, all of these emit harmful
chemicals into the air and lead to polluti on. In many cases, when we
use these chemicals at offices or homes with no or little ventilation, we
may fall sick if we breathe them in for an extended period of time.
 Deforestation: Deforestation affects the atmosphere in more than a
few ways. Forests ac t as sponges for carbon dioxide through a process
called carbon sequestration. Trees amass carbon dioxide in their plant
tissue as they take in this gas to undertake food -making. In effect, this
action gets rid of carbon dioxide from the air. When forests are burned
and destroyed on purpose and to tremendous extents, this storage area
for carbon dioxide is removed, thus increasing the amount of
atmospheric carbon dioxide. Wood fires are also another effect of munotes.in

77 deforestation and can be cause air pollution by discharging particulate
matter into the air. These particles can become lodged in the
respiratory system, causing irritation to lung tissues. The particles can
also worsen existing health conditions such as asthma and other
respiratory disorders.
 Smoking: One can still be at a risk of the dangers of smoking even if
they are a non -smoker. The University of Minnesota estimated that up
to 90 percent of the population is habitually exposed to second -hand
smoke. Tobacco smoke contains up to 40 carcinogens, makin g it an
especially fatal form of air pollution. If you have smokers in the family
air purifiers will ensure that the other members don’t suffers from
second hand smoke.
 Indoor Air Pollution: Use of toxic products also called as Volatile
Organic Compounds ( VOCs), inadequate ventilation, uneven
temperature, and humidity level can cause indoor air pollution,
whether you are in office, school or at your comfortable home. House
air pollution can take place due to ignorant factors, for instance,
smoking tobacco i nside a room or leaving mold infected wall
untreated. Use of wood stove or space heaters is capable to increase
the humidity level which can directly affect the health a person in no
time.
 Microbial Decaying Process: Manufacturing, chemical, and textiles
industries release a large number of carbon monoxides, hydrocarbons,
chemicals and organic compounds which contaminate our
environment. Bacteria and fungi play a fundamental role in the
biogeochemical cycles in nature. They are the key indicators of
abnorma l environmental conditions. Decaying of these
microorganisms present in the surrounding releases methane gas which
is highly toxic. Breathing toxic gas like methane may lead to death.
 Open Burning of Garbage Waste: Open burning of garbage is much
more harm ful to your health and the environment than one may think.
As per Engage EPW, Delhi Air Pollution is choking public health.
Delhi generates a whopping 9500 tons of waste every day, which
makes it India’s second waste dumping city. Exposure to open burning
of garbage waste can pose serious health risk including cancer, liver
issues, impairment of immune system, reproductive functions; can also
affect the developing nervous system.
 Agricultural Activities: Agricultural activities have had a serious
impact on the decreasing air quality. To begin with pesticides and
fertilizers are the main source to contaminate the surrounding air.
Nowadays, pesticides and fertilizers are mixed with new invasive
species which are not found in nature, for quick growth of the cro ps
and vegetation. Once they are sprayed over, the smell and the effect of
the pesticides are left in the air. Some mix with water and some seeps
into the ground which not only destroys the crops but also causes
numerous health -related issues. munotes.in

Page 78

Environmental Economics
78  Use of chemi cal and synthetic products: Talking about air pollution,
we always consider outdoor air pollution dangerous for our lives but
never talk about indoor air pollution. Household products cause indoor
air pollution which is 10 times more harmful than outdoor a ir
pollution. Volatile Organic Compounds (VOCs) found in paints,
cleaners and personal care products such as perfume and deodorants
are a reason for common heath issues. Risks like asthma or other
respiratory issues and lung disease are other issues cause by inhaling
poor house air quality.
The rate with which the air pollution is increasing in the country,
immediate action has become an absolute necessity. Not only does it
affect human lives but also causes havoc in nature.

Nelson Mandela once expressed hi s concern about the air pollution
and particularly its effect on human lives, said, “Everyone has the right
to an environment that is not harmful to their health or well -being; and
to have that environment protected, for the benefit of present and
future g enerations.”
o Conserve the energy is the first step towards a better future with
clean air to breathe.
o Understanding the concept and imbibing the habit of reducing,
reuse, and recycle is crucial.
o Use public transport whenever it is feasible to save fuel and
reduce vehicle pollution.
Effects of Air Pollution:
 Accelerated Global Warming. Air pollution directly accelerates
the rate at which global warming happens by depleting the Ozone
layer. Global warming refers to the increased temperatures Earth
continues to experience. These higher temperatures lead to the
melting of the polar ice caps and icebergs, which elevates sea levels
and creates concern for the human race.
 Human Respiratory And Heart Concerns. Air pollution is known
to cause irritation in the eyes , lungs, nose, and throat. It creates
respiratory problems and exacerbates existing conditions such as
asthma and emphysema. When continually exposed to air pollution,
humans become at higher risk for cardiovascular disease. Air filled
with toxins can have a number of adverse effects on the arteries, and
have even been a contributor to heart attacks. The effects of air
pollution are alarming. They are known to create several respiratory
and heart conditions like asthma, chronic bronchitis, emphysema,
heart attacks and strokes along with cancer, among other threats to
the body. Several million are known to have died due to the dire ct or
indirect effects of Air pollution.

79  Wildlife Endangerment. Most diseases and conditions that humans
are susceptible to, animals are as well. Air pollution creates many of
the same issues that humans face. Heavily polluted areas force
inhabitants to s eek new homes, which can negatively impact the
ecosystem. Toxic chemicals, which we’ll discuss in the next bullet,
also deposit over surfaces of water that can lead to the endangerment
of marine life animals.
 Acid Rain. When air pollution, specifically sul fur oxides and
nitrogen oxides, are released into sky through fossil fuel burning, it
creates the phenomenon known as acid rain. Water, high in the
atmosphere, combines with these chemicals and becomes acidic in
nature. It then scatters the ground, disguis ed as normal rainfall. Acid
rain has been known to cause harm to humans and animals alike, and
even damage crops.
 Child Health Problems Air pollution is detrimental to your health
even before you take your first breath. Exposure to high air pollution
level s during pregnancy causes miscarriages as well as premature
birth, autism, asthma and spectrum disorder in young children. It
also has the potential to damage early brain development in a child
and cause pneumonia that kills almost a million children below 5
years. Children are at a greater risk of short term respiratory
infections and pulmonary diseases in areas exposed to air pollutants .
 Eutrophication. Eutrophication is a condition where a high amount
of nitrogen present in some pollutants gets developed on the sea
surface an d turns itself into algae and adversely affects fish, plants,
and animal species.
 Effect on Wildlife. Just like humans, animals also face some
devastating effects of air pollution. Toxic chemicals present in the air
can force wildlife species to move to a new place and change their
habitat. The toxic pollutants deposit over the surface of the water and
can also affect sea anim als.
 Depletion of the Ozone Layer. Ozone exists in the Earth’s
stratosphere and is responsible for protecting humans from harmful
ultraviolet (UV) rays. Earth’s ozone layer is depleting due to the
presence of chlorofluorocarbons, hydro chlorofluorocarbons in the
atmosphere. As the ozone layer becomes thin, it wil l emit harmful
rays back on earth and can cause skin and eye -related problems. UV
rays also have the capability to affect crops.
Measures to Control Air Pollution
 Use thePublic Mode of Transportation.
Encourage people to use more and more public modes of t ransportation to
reduce pollution. Also, try to make use of carpooling. If you and your
colleagues come from the same locality and have the same timings, you
can explore this option to save energy and money. munotes.in

Page 80

Environmental Economics
80  Better Household Practices
Discard fireplaces an d/or wooden stoves used for heating homes. Use gas
logs in place of wood. Also, eliminate the use of gas -powered lawn and
gardening equipment. Avoid setting fire to garbage, dry leaves, or other
materials in your yard, and lighting bonfires in the open. Tr y to mulch or
compost your yard waste. Use cleaning products and paints that are
environmentally friendly. When you’re leaving home, be sure to turn off
the lights, TV, and any other electronic appliances.

Fossil fuel plants are a major cause of air pollut ants, and the less energy
you need, the less we have to rely on those plants to generate
electricity.This also means turning to energy efficient devices when
possible. Fluorescent lightbulbs over the course of their lifespan can
reduce energy consumption w hile adding significant savings to your
pocket.

 Conserve Energy
Switch off fans and lights when you are going out. A large number of
fossil fuels are burnt to produce electricity. You can save the environment
from degradation by reducing the number of foss il fuels to be burned.

 Understand the Concept of Reduce, Reuse and Recycle
Do not throw away items that are of no use to you. Instead, reuse them for
some other purpose. For example, you can use old jars to store cereals or
pulses.

 Emphasis on Clean Energy Resources
Use of Clean energy technologies like solar, wind and geothermal is on
the rise these days. Governments of various countries have been providing
grants to consumers who are interested in installing solar panels for their
homes. Undoubtedly, this can go a long way to curb air pollution.

 Use Energy -Efficient Devices
CFL lights consume less electricity than their counterparts. They live
longer, consume less electricity, lead to lower electricity bills, and also
help you to reduce pollution by consu ming less energy.

 Become An Advocate For Clean Energy.
Every day, technology continues to advance that improves the efficiency
and cost of clean energy such as solar, wind, and geothermal. These types
of energy sources create much less air pollution. Even nuclear is leaps and
bounds better than traditional fossil fuel plants when it comes to air
pollution. Find ways to promote and educate the public on clean energy
alternatives. A small contribution goes a long way in the grand scheme of
things. munotes.in

81 (B) Water Pollution: Water is an essential resource of life on earth. The
quality of water is the most important factor. Fresh water is a scarce
commodity with greatest amount locked in glaciers and ice -caps. Water
pollution simply means contamination of water due to any external
material or in other words, introduction of something to natural water
which makes in unsuitable for human consumption. WHO has defined
water pollution as “any foreign material either from natural or other
sources that may counterminate wat er and makes it harmful to life, cause
of their toxicity leads to reduction of normal oxygen level of water causes
aesthetically unpalatable afflicts as spread of epidemic diseases”.
Jacques Yves Cousteau said that “Water and air, the two essential fluids
on which all life depends, have become global garbage cans”. In simple
words, the contamination of water bodies is water pollution. It is t he abuse
of lakes, ponds, oceans, rivers, reservoirs, etc. Pollution of water usually
occurs when substances discharged in it negatively modify the water.
This discharge of pollutants can be direct as well as indirect.
There are many causes of water pollution.
 Industrial Waste: Industries and industrial sites across the worl d
are a major contributor to water pollution. Many industrial sites produce
waste in the form of toxic chemicals and pollutants, and though regulated,
some still do not have proper waste management systems in place. In
those rare cases, industrial waste is dumped into nearby freshwater
systems. When industrial waste is not treated properly (or worse, not
treated at all), it can very easily pollute the freshwater systems that it
comes into contact with.
Industrial waste from agricultural sites, mines and ma nufacturing plants
can make its way into rivers, streams and other bodies of water that lead
directly to the sea. The toxic chemicals in the waste produced by these
industries not only have the potential to make water unsafe for human
consumption, they can also cause the temperature in freshwater systems to
change, making them dangerous for many water dwelling organisms.

 Marine Dumping: The process of marine dumping is exactly what
it sounds like, dumping garbage into the waters of the ocean. It might
seem crazy, but household garbage is still collected and dumped into
oceans by many countries across the world. Most of these items can take
anywhere from two to 200 years to decompose completely.
 Sewage and Wastewater: Harmful chemicals, bacteria and
pathogens can be found in sewage and wastewater even when it’s been
treated. Sewage and wastewater from each household is released into the
sea w ith fresh water. The pathogens and bacteria found in that wastewater
breed disease, and therefore are a cause of health -related issues in humans
and animals alike.
 Oil Leaks and Spills: The age -old phrase “like water and oil” is
used when describing two t hings that do not mix easily or at all. Just as the
saying states, water and oil do not mix, and oil does not dissolve in water. munotes.in

Page 82

Environmental Economics
82 Large oil spills and oil leaks, while often accidental, are a major cause of
water pollution. Leaks and spills often are caused by oil drilling operations
in the ocean or ships that transport oil. wildlife.
 Agriculture: In order to protect their crops from bacteria and
insects, farmers often use chemicals and pesticides. When these
substances seep into the groundwater, they can harm animals, plants and
humans. Additionally, when it rains, the chemicals mix with rainwater,
which then flows into rivers and streams that filter into the ocean, causing
further water pollution.
 Global Warming: Rising temperatures due to global warming are a
major concern in terms of water pollution. Global warming causes water
temperatures to rise, which can kill water -dwelling animals. When large
die-offs occur, it further pollutes the water supply, exacerbating the
issue. There are many everyday ways we can help reduce global warming ,
which will in turn help lower water pollution. These methods include
recycling, c arpooling and using CFL bulbs in our houses.
 Radioactive Waste: Radioactive waste from facilities that create
nuclear energy can be extremely hazardous to the environment and must
be disposed of properly. This is because uranium, the element used in the
creation of nuclear energy, is a highly toxic chemical. Unfortunately,
accidents still occur at these facilities, and toxic waste is released into the
environment. The coal and gas industries are, in many ways, no better.
This is one of the major impetuses behind the development of alternative,
clean sources of energy, including solar and wind.
 Mining Activities: Mining is the process of crushing the rock and
extracting coal and other minerals from the underground. These elements,
when extracted in the raw form, contain harmful chemicals and can
increase the number of toxic elements when mixed up with water, which
may result in health problems. Mining activities emit a large amount of
metal waste and sulfides from the rocks, which is harmful to the water.
 Chemical fertilizers and pesticides: Chemical fertilizers and
pesticides are used by farmers to protect crops from insects and bacterias.
They are useful for the plant’s growth. However, when these chemicals
are mixed up with water, they produce harmful poll utants for plants and
animals. Also, when it rains, the chemicals mix up with rainwater and
flow down into rivers and canals, which pose seri ous damages for aquatic
animals.
 Urban Development: As the population has grown exponentially,
so has the demand for housing, food, and cloth. As more cities and towns
are developed, they have resulted in increasing use of fertilizers to produce
more food, soil erosion due to deforestation, rise in construction activities,
inadequate sewer collection and treatment, landfills as more garbage is
produced, increase in chemicals from industries to produce more
materials.

83 Effects of Water Pollution
1. Affects Aquatic Life: Water contamination has a significant impact
on aquatic life. It affects their metabolism and behaviour, as well as
causing disease and death. Dioxin is a toxin that causes a variety of issues,
ranging from reproductive issues to uncontrolled cell development and
cancer. This chemical accumulates in fish, poultry, and meat. Chemicals
like these make their way up the food chain before entering the human
body.
2. Affects Food chain: Water contamination may have a significant
influence on the food c hain. It upsets the food chain. Cadmium and lead
are two hazardous chemicals that enter the food chain via animals (fish
when ingested by animals and people) and can continue to disturb at
greater levels.
3. Groundwater contamination: Pesticides and fertilise rs used in
agricultural production pollute groundwater as well as our ecology. If this
groundwater is directly delivered to our home via bore -wells or tube -
wells, it will cause a multitude of health issues.
4. Affects Human Health: Pollution affects humans, and faecal matter
in water sources can cause illnesses such as hepatitis. Poor drinking water
treatment and contaminated water can always lead to an epidemic of
infectious illnesses like cholera.Water pollution has very negative effects
on public health. A lot of diseases result from drinking or being in contact
with contaminated water, such as diarrhea, cholera, typhoid, dysentery or
skin infections. In zones where there is no available drinking water, the
main risk is dehydration obviously.
5. High TDS in wa ter: Water is the best solvent since it quickly
dissolves a wide range of compounds. TDS in drinking water should be
less than 500 mg/litre. The presence of a high level of TDS in water can
cause a variety of health issues in humans.
Measures to Control wa ter Pollution
1. Wastewater treatment: Wastewater treatment consists of removing
pollutants from wastewater through a physical, chemical or biological
process. The more efficient these processes are, the cleaner the water
becomes.
2. Green agriculture: Globally, agriculture accounts for 70% of water
resources, so it is essential to have climate -friendly crops, efficient
irrigation that reduces the need for water and energy -efficient food
production. Green agriculture is also crucial to limit the chemicals t hat
enter the water.
3. Stormwater management: Stormwater management is the effort to
reduce runoff of rainwater or melted snow into streets, lawns and other
sites and the improvement of water quality” according to the US
Environmental Protection Agency (E PA). It is important to avoid munotes.in

Page 84

Environmental Economics
84 pollutants from contaminating the water and helps to use water more
efficiently.
4. Air pollution prevention: Air pollution has a direct impact on water
contamination as 25% of human induced CO2 emissions are absorbed by
oceans. This pollution causes a rapid acidification of our oceans, and
threatens marine life and corals. Preventing air pollution is the best way to
prevent this from happening.
5. Plastic waste reduction: 80% of plastic in our oceans is from land
sources. In order to reduce the amount of plastic entering our ocean, we
need to both reduce our use of plastic globally, and to improve plastic
waste management.
6. Water conservation: Without wat er conservation, we won’t go very
far. It is central in making sure the world has better access to clean water.
It means being aware that water is a scarce resource , taking care of it
accordin gly, and managing it responsibly.
(C) Noise Pollution: Noise pollution can be defined as “ an undesirable
and harmful sound in the environment, the presence of which causes
discomfort to individuals and also to the animals”. By definition, noise
pollution takes place when there is either an excessive amount of noise or
an unpleasant sound that causes a temporary disruption in the natural
balance. This definition is usually applicable to sounds or noises that are
unnatural in either their volume or their production. Our environment is
such that it has become difficult to escape the noise. Even electrical
appliances at home have a constant hum or beeping sound. By and large,
lack of urban planning increases the exposure to unwanted sounds. This is
why understanding noise pollution is necessary to curb it in time.
Causes of Noise Pollution:
 Industrialization: Most of the industries use big mach ines which
are capable of producing a large amount of noise. Apart from that, various
equipment like compressors, generators, exhaust fans, grinding mills also
participates in producing big noise. We are familiar with the sight of
workers in these factorie s and industries wearing earplugs to minimize the
effect of noise.However, even after taking precautionary measures like
these, extensive exposure to high levels of noise might damage their
hearing abilities in the long run.
 Poor Urban Planning: In most of the developing countries, poor
urban planning also plays a vital role. Congested houses, large families
sharing small space, fight over parking, frequent fights over basic
amenities lead to noise pollution, which may disrupt the environment of
society .Noise pollution in urban settings may also be caused when
residential properties and industrial buildings are in proximity. In
situations like these, the noise from the nearby industrial property might
hinder the basic well -being of the individuals living in residential
properties.It doesn’t just affect their slee p and hours of rest but also has an
adverse effect on the development and well -being of children. munotes.in

Page 85

85  Social Events: Noise is at its peak in most of the social events.
Whether it is marriage, parties, pub, disc or place of worship, people
normally flout rules s et by the local administration and create a nuisance
in the area.People play songs on full volume and dance till midnight,
which makes the condition of people living nearby pretty worse. In
markets, you can see people selling clothes via making a loud nois e to
attract the attention of people.While this may not seem like much at the
outset, over time, it affects the hearing abilities of the individuals who are
constantly exposed to these sounds.
 Transportation: A large number of vehicles on roads, airplanes
flying over houses, underground trains produce heavy noise, and people
find it difficult to get accustomed to that. The high noise leads to a
situation wherein a normal person loses the ability to hear properly.
 Construction Activities: Under construction activities like mining ,
construction of brid ges, dams, buildings, stations, roads, flyovers takes
place in almost every part of the world. These construction activities take
place every da y as we need more buildings, bridges to accommodate more
people. However, while this does help us to some degree, in the long run,
the noise from construction activities hinders the hearing abilities of
individuals exposed to this sound. A part of it inclu des construction
workers who participate in these activities, while another part of it consists
of people who encounter this noise either from their homes or while
traveling. Even remodelling buildings can cause hearing loss when
performed in enclosed spac es. The sound of jackhammers chipping away
at concrete is enough to upset nearby workers and residents.
 Household Chores: We people are surrounded by gadgets and use
them extensively in our daily life . Gadgets like TV, mobile, mixer grinder,
pressure cooker, vacuum cleaners, washing machine and dryer, cooler, air
conditioners are minor contributors to the amount of noise that is
produced. Still, it affects the quality of life of your neighborhood in a bad
way. While this form of pollution may seem harmless, it, in fact, has far -
reaching consequences. The adverse effects on the health of the
environment are quite severe. Not only is the local wildlife affected by
pollution , but humans also face a number of problems due to it.
 Noise From Air Traffic: While many find it difficult to believe, air
traffic too contributes to significant levels of noise pollution. Noise from a
single aircraft may pr oduce sounds of up to 130 dB. Now, imagine the
amount of noise produced by the numerous aircraft traveling our airspace.
 Catering and Nightlife: When the weather is good, restaurants,
bars, and terraces spill outside. Late night parties continue with loud music
and unnecessary noise made by the party mongers. These can produce
more than 100 dB. The noise from pubs and clubs are also included.
 Animals’ Sound: The noise made by animals cannot go unnoticed,
particularly a howling or barking dog. These can produce noise around 60 -
80 dB. munotes.in

Page 86

Effects of Noise Pollution:
1. Hearing Problems: Any unwanted sound that our ears have not been
built to filter can cause problems within the body. Our ears can take in a
certain range of sounds without getting damaged. Man-made noises such
as jackhammers, horns, machinery, airplanes , and even vehicles can be too
loud for our hearing range. Constant exposure to loud levels of noise can
easily result in the damage of our eardrums and loss of hearing, causing
tinnitus or deafness. It also reduces our sensitivity to sounds that our ears
pick up unconsciously to regulate our body’s rhythm.
2. Psychological Issues: Excessive noise pollution in working areas such
as offices, construction sites, bars and even in our homes can influence
psychological health. Studies show that the occurrence of aggressive
behavior, disturbance of sleep, constant stress, fatigue, depression,
anxiety, hysteria and hypertension in humans as well as animals can be
linked to excessive noise levels. The level of irritation increases with
increased noise, and people tend to become less and less patient. These, in
turn, can cause more severe and chronic health issues later in life.
3. Ph ysical Problems: Noise pollution can cause headaches, high blood
pressure, respiratory agitation, racing pulse, and, in exposure to extremely
loud, constant noise, gastritis, colitis and even heart attacks may occur.
4. Cognitive Issues & Behavioral Change s: Noise affects brain
responses and people’s ability to focus, which can lead to low -
performance levels over time. Like other sound waves, too much noise
when it goes to the brain leads to lower response rates as well as making
the mind dull. It is also p oor for memory, making it hard to study. The
studies have shown that school children living near railway stations or
airports have problems in learning. Research has shown that people who
live near airports or busy roads, usually have a higher incidence of
headaches, take more sleeping pills and sedatives, are more prone to minor
accidents, and are more likely to seek psychiatric treat ment.
5. Sleeping Disorders: While it may not seem like much at this point,
excessively high levels of noise are likely to hamper your sleeping pattern,
thereby leading to irritation and uncomfortable situations. Without a good
night’s sleep, you might experience multiple problems related to fatigue.
This will affect your performance in the office as well as at home. It is
therefore recommended to take a sound sleep to give your body proper
rest. If a certain noise is disturbing your sleep, take an actio nable measure
to reduce it. While in some instances, it is completely unavoidable; there
are other instances (like noise from TV or gadgets) that can be easily
avoided by making good lifestyle changes. Interestingly, our ears need rest
for 16 hours and eve n more to make up for two hours of exposure to 100
dB.
6. Cardiovascular Issues : Blood pressure levels, cardiovascular disease,
and stress -related heart problems are on the rise. Studies suggest that high -munotes.in

Page 87

Supplementary An alytical
Tools and Environmental
Issues - II
87 intensity noise causes high blood pressure and incr eases heartbeat rate as it
disrupts the normal blood flow. Since bringing these rates to a manageable
level depends on our understanding of noise pollution, we need to be wary
of the ill -effects and tackle these situations mindfully.
7. Trouble Communicati ng: High decibel noise can put trouble and
affect free communication between people. This may lead to
misunderstanding, and you may get difficult understanding the other
person. Constant sharp noise can give you a severe headache and disturb
your emotional balance.
8. Effect on Wildlife: Wildlife faces far more problems than humans
because of noise pollution since they are more dependent on sound.
Animals develop a better sense of hearing than us since their survival
depends on it. A recent study published in Biology Letters found that
human -created noise affects a wide range of animals. The ill -effects of
excessive noise begin at home. Pets react more aggressively in households
where there is constant noise. They become disoriented more ea sily and
face many behavioral problems. In nature, animals may suffer from
hearing loss, which makes them easy prey and leads to dwindling
popul ations . Others become inefficient at hunting, disturbing the balance
of the eco -system.
9. Effects on Species Depending on Mating Call: Species that depend on
mating calls to reproduce are often unable to hear these calls due to
excessive man -made noise. As a result, they are unable to reproduce and
cause declining populations. Others require sound waves to locate and find
their way when migrating. Disturbing their sound signals means they get
lost easily and do not migrate when they should. To cope up with the
increasing sound around them, animals are becoming louder, which may
further add to the pollution levels . This is why understanding noise
pollution can help us lower the impact it has on the environment .
Measures to control Noise Pollution: WHO agrees that awareness of
noise pollution is essential to beat this invisible enemy. As of now, there
are not many solutions to reduce sound pollution. However, governments
can help in the following ways:
 Establishing regulations that include preventive and corrective
measures.
 Governments can t ake measures such as protecting certain areas, parts
of the countryside, areas of natural interest, city parks, etc. to ensure
noise management and reduce noise pollution.
 The mandatory separation between residential zones and sources of
noise, like airpor ts.
 Creating pedestrian areas where traffic is not allowed to enter other
than offload goods at certain times.
 Fines for exceeding noise limits. munotes.in

Page 88

Environmental Economics
88  Other ways to battle noise pollution are by controlling the sound levels
in clubs, bars, parties, and discos.
 Removal of public loudspeakers is another way in which pollution can
be countered.
 Again, better urban planning can help create ‘No -Noise’ zones, where
honking and indus trial noise is not tolerated.
 Replacing traditional asphalt with more efficient options can also help
reduce traffic noise by up to 3 dB.

Earlier there was a perfect balance between ozone consumption and ozone
reformed. This balance has beebn disturbed as a result of increasing
human activities especially, the manufacture and use of synthetic chemical
substances known as CFCs and HCFCs. Suc h chlorine containing
compounds are used in aerosols, refrigeration, solvents, and foam
insulation. Through a number of complicated chemical chain reactions,
even small amount of theses chemical compounds are able to destroy very
large quantities of ozone. As a result of this, ozone is broken down at a
faster rate than it is forming and parts of ozone layers are becoming
thinner and ‘ozone holes’ are being developed.
“The ozone layer is a region in the earth’s stratosphere that contains high
concentrations of ozone and protects the earth from the harmful ultraviolet
radiations of the sun.”Ozone layer depletion is the gradual thinning of the
earth’s ozone layer in the upper atmosphere caused due to the release of
chemical compounds containing gaseous bromine or chlorine from
industries or other human activities.”

Fig 6.1 Ozone Depletion
Ozone Hole
Ozone hole is created in the region where ozone layer has been depleted.
The term “Ozone hole” is applied when the depletion level is below 200
Dobson Unit (D.U) . Ozone holes are first discovered in Antarctica in
1970. Few years ago, ozone holes are also discovered in arctic region.
Since 2000 rate of ozone depletion is increasing 0.5 percent per year. Due
to depletion of Ozone UV rays are penetrating in troposphe re and leading munotes.in

89 to more ozone formation in troposphere which is causing injurious effects
on our health as ozone is toxic for our body.
6.2.1.Causes of Ozone Depletion
1. Chlorofluorocarbon: Ozone depletion occurs when the natural
balance between the productio n and destruction of stratospheric ozone is
disturbed. Although natural phenomenon can cause ozone depletion but
human activities such as CFCs are now accepted as major cause of
depletion . All ozone depleting chemicals contain chlorine and bromine .
CFCs are highly volatile and non combustible so they are very quickly
evaporated and can easily reach in stratosphere where ozone is present
here they start depleting ozone molecules. These CFCs have also adverse
affects on human health. According to the chemic al model for ozone
destruction proposed about 20 years ago, the photolysis of Cl 2O2 is key to
ozone depletion reaction. But now atmospheric researchers studied that the
rate of this reaction is not extremely high as it was thought previously so
we can no longer say that CFCs are the main cause of ozone depletion.
2. Unregulated Launches of Rockets: Another major cause of large
scale ozone depletion is Rocket launches. It has been studied that
unregulated rocket launches can result in much more ozone depletion than
CFCs. It is estimated that if rocket launches will be let unregulated then it
would cause huge ozone loss by the year 2050 than the CFCs have done.
3. Global Warming: Global warming also leads to ozone layer
depletion. Due to global warming and greenhous e effect most of the heat
is trapped in troposphere which is the layer below the stratosphere. As we
all know ozone is present in stratosphere so heat don’t reach troposphere
and it remain cold as recovery of ozone layer requires maximum sunlight
and heat so it leads to depletion of ozone layer.
4. Nitrogenous Compound: Nitrogenous Compounds emitted by
human activities in small amount like NO, N 2O and NO 2 are considered to
be greatly responsible for the depletion of ozone layer.NO 2, NO, N 2O are
responsible for ozone depletion. The sources of Nitrogen Oxides are
mainly explosions of thermonuclear weapons, agricultural fertilizers and
industrial emissions.
5. Bromine Compounds: These are called HydrobromoFuorocarbons
(HBFCs) and are used in fire extinguishers. Each bromine atom destroys a
hundred times more ozone molecules than a chlorine atom does.
6. Natural Causes: The ozone layer is depleted by a number of natural
causes like the sunspot cycle, volcanic eruption. However, the percentage
effect is less i.e around 1 -3%.
6.2.2 . Effects of Ozone Depletion: Ozone depletion is affecting the
human health and environment negatively, as it allows the penetration of
UV radiations to reach the Earth. These radiations can cause severe
diseases in humans such as skin cancer, eye damage and genetic mutations
etc. Furthermore the ozone depletion is affecting the aquatic life, munotes.in

Page 90

Environmental Economics
90 biogeochemical cycles, air quality and also contributing in Global
warming but in this review paper our main focus is on the effects of ozone
depletion on huma n health.
1. Effects oh Human Health and Animal Health: People become
vulnerable due to the increase in the incidence of morbidity from eye
diseases, skin cancer and infectious diseases. In light skin coloured
populations, UV_B radiation is the main risk factor for the development of
Non-Melanoma skin cancer. The major cause of blindness in this world is
cataracts. There would be 0.3% - 0.6% increase in risk of cataract if there
will be 1% decrease in Ozone level. Eye lens can be damaged by oxidative
agents. Oxidative oxygen produced by UV radiation can severel y damage
eye lens and cornea of eye is also badly damaged by UV radiation.
Photokeratitis, cataract, blindness all are caused due to UV rays. Exposure
to UV radiations can cause skin cancer. UV radiations alter the structure
of biomolecules and thus lead t o different diseases .Skin is the most often
exposed part of body to UV radiations There are two types of skin cancer,
Melanoma and Non -melanoma. Melanoma is most serious form of cancer
and is often fatal, while non -melanoma is most common type and less
fatal. Depletion of ozone layer leads to both Sun burn and skin cancer. UV
radiations are also responsible for breast cancer and leukemia.More
increase in depletion of ozone results in more decrease in immune system.
Short exposure to UV -B radiations can cau se the DNA damage because
UV radiations can disturb biomolecules such as lipids, proteins and
Nucliec acids. Due to UV -B radiations there would be cryptic transposable
elements which may lead towards the mutations which is more dangerous
than the immediate DNA damage.
2. Effect of Food Shortage on Human Population: Depletion of
ozone layer is also causing the problem of food shortage to humans. UV
radiations are disturbing developmental and physiological processes which
is decreasing the productivity of crops. As humans are heavily dependent
on crops for food so there is a great chance if depletion of ozone layer is
not checked it may cause seriously shortage of food to humans .
Researches also show that UV radiations can also be used to enhance yield
of crops by the use and application of phytohormones
3. Effects on Plants: Psychological processes of plants are affected by
UV-B radiation.
Response to UV -B also varies voraciously among different species.
Therefore, in agriculture, it becomes necessary to use more U V-B tolerant
species. In forests and grasslands, it results in changing the composition of
species. There are several indirect changes like plant form, biomass
allocation of the plant, timing of development phases triggered due to UV -
B radiation.

4. Effects o n Aquatic Ecosystem: More exposure to UV -B radiation
has affected motility in phytoplanktons which results in reduced survival
rates of these organisms. munotes.in

Page 91

Supplementary An alytical
Tools and Environmental
Issues - II
91 UV-B radiation has been found to cause damage in the early development
stages of fish, crabs, amphibian s and various other animals. The more
severe effect is a decrease in reproductive capacity.

5. Effects on Air Quality: Reduction of Ozone in upper layers of
atmosphere and the direct increase of UV -B radiation penetrating to the
lower atmosphere results in hi gher photodissociation rates of gases that
control the chemical reactivity of the Troposphere. Products formed due to
these reactions are known to have adverse effects on human health, plants
and outdoor materials. Increase in tropospheric reactivity will lead to
increased production of particulates due to oxidation and nucleation of
sulfur due to anthropogenic and natural causes.
6. Effects on Material: Materials like polymers, naturally occurring
biopolymers and some other materials of commercial interest ar e affected
by UV radiations. Increase in solar UV -B content due to partial ozone
depletion accelerates the photodegradation rate of these materials and
therefore limits their life outdoors.
6.2.3 Solutions to Ozone Depletion: Thus, instead of using chemicals, one
should stop using pesticides and switch to natural methods to get rid of
pests. A significant amount of greenhouse gases are produced by cars,
contributing to global warming as well as ozone depletion. The use of
vehicles should therefore be reduced as far as possible. Many of the
materials used for cleaning have chemicals that damage the ozone layer.
We should substitute eco -friendly goods for that. Maintain air
conditioners, as CFC escapes into the atmosphere via their malfunctions.

1. Desi st From Using Pesticides
Pesticides are great chemicals to rid your farm of pests and weeds, but
they contribute enormously to ozone layer depletion. The surefire solution
to get rid of pests and weeds is to apply natural methods. Just weed your
farm manua lly and use alternative eco -friendly chemicals to alleviate
pests.

2. Discourage Driving of Private Vehicles
The easiest technique to minimize ozone depl etion is to limit the number
of vehicles on the road. These vehicles emit a lot of greenhouse gases that
eventually form smog , a catalyst in the depletion of the ozone layer.

3. Utilize Environmentally Friendly Cleaning Products
Most household cleaning products are loaded with harsh chemicals that
find way to the atmosphere, eventually contributing to the degradation of
the ozone layer. Use natural and environmentally friendly cleaning
products to arrest this situation.

4. Prohibit the Use of Harmful Nitrous Oxide
The Montreal Protocol forme d in 1989 helped a lot in the limitation of
Chlorofluorocarbons (CFCs). However, the protocol never covered nitrous
oxide, which is a known harmful chemical that can destroy the ozone munotes.in

Page 92

Environmental Economics
92 layer. Nitrous oxide is still in use today. Governments must take action
now and outlaw nitrous oxide use to reduce the rate of ozone depletion.

6.3 GREEN HOUSE GAS EMISSION:

Greenhouse gas, any gas that has the property of absorbing infrared
radiation (net heat energy) emitted from Earth's surface and reradiating it
back to E arth's surface, thus contributing to the greenhouse effect. Carbon
dioxide, methane, and water vapour are the most important greenhouse
gases.

Gases of natural origin (water vapour) or anthropogenic (linked to human
activities) absorbing and release again part of the solar rays (infrared
radiation), phenomena at the origin of the greenhouse effect.

The main gases responsible for the greenhouse effect, linked to human
activities, are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O)
and the fluorinate d gases (HFC, PFC, SF6 and NF3).

Emissions of these gases are weighted by their global warming potential
(GWP) and expressed in CO2 equivalents.

The six gases monitored in the Kyoto protocol are carbon dioxide (CO2),
methane (CH4), nitrous oxide (N2O), HFC and PFC.It is the emission into
the earth's atmosphere of any of various gases, especially carbon dioxide,
that contribute to the greenhouse effect.

Identified by scientists as far back as 1896, the greenhouse effect is the
natural warming of the earth that results when gases in the atmosphere trap
heat from the sun that would otherwise escape into space.

Since the start of the Industrial Revolution and the advent of coal -powered
steam engines, human activities have vastly increased the volume of
greenh ouse gases emitted into the atmosphere. It is estimated that between
1750 and 2011, atmospheric concentrations of carbon dioxide increased by
40 percent, methane by 150 percent, and nitrous oxide by 20 percent. In
the late 1920s, we started adding man -made fluorinated gases like
chlorofluorocarbons, or CFCs, to the mix.

There are several ways of measuring greenhouse gas emissions. Some
variables that have been reported include:

 Definition of measurement boundaries: Emissions can be attributed
geographica lly, to the area where they were emitted (the territory
principle) or by the activity principle to the territory that produced the
emissions. These two principles result in different totals when measuring,
for example, electricity importation from one coun try to another, or
emissions at an international airport. munotes.in

Page 93

Supplementary An alytical
Tools and Environmental
Issues - II
93  Time horizon of different gases: The contribution of given
greenhouse gas is reported as a CO 2 equivalent. The calculation to
determine this takes into account how long that gas remains in the
atmos phere. This is not always known accuratelyand calculations must be
regularly updated to reflect new information.
The measurement protocol itself: This may be via direct measurement or
estimation. The four main methods are the emission factor -based method,
mass balance method, predictive emissions monitoring systems, and
continuous emissions monitoring systems. These methods differ in
accuracy, cost, and usability. Public information from space -based
measurements of carbon dioxide by Climate Trace is expected to reveal
individual large plants before the 2021 United Nations Climate Change
Conference .

6.3.1 Five Major Greenhouse Gases
The most significant gases that caus e global warming via the greenhouse
effect are the following:

a) Carbon Dioxide : Accounting for about 76 percent of global human -
caused emissions, carbon dioxide (CO 2) sticks around for quite a while.
Once it’s emitted into the atmosphere, 40 percent still remains after 100
years, 20 percent after 1,000 years, and 10 percent as long as 10,000
years later.

b) Methane: Although methane (CH 4) persists in the atmosphere for far
less time than carbon dioxide ( about a decade ), it is much more potent in
terms of the greenhouse effect. In fact, pound for pound, its global
warming impact is 25 times greater than that of carbon dioxide over a 100 -
year period. Globally it acco unts for approximately 16 percent of human -
generated greenhouse gas emissions.

c) Nitrous Oxide : Nitrous oxide (N 2O) is a powerful greenhouse gas: It
has a GWP 300 times that of carbon dioxide on a 100 -year time scale, and
it remains in the atmosphere, on average, a little more than a century. It
accounts for about 6 percent of human -caused greenhouse gas emissions
worldwide.

d) Fluorinated Gases : Emitted from a variety of manufacturing and
industrial processes, fluorinated gases are man -made. There are four main
categories: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur
hexafluoride (SF 6), and nitrogen trifluoride (NF 3).

Although fluorinated gases are emitted in smaller quantities than other
greenhouse gases (they account for just 2 percent of man -made global
greenhouse gas emissions), they trap substantially more heat. Indeed, the
GWP for these gases can be in the thousands to tens of thousands, and
they have long atmospheric lifetimes, in some cases lasting tens of
thousands of years. munotes.in

Page 94

Environmental Economics
94 HFCs are used as a replacement for ozone -depleting chlorofluorocarbons
(CFCs) and hydrochlorofluorocarbons (HCFCs), usually in air
conditioners and refrigerators, but some are being phased out because of
their high GWP. Replacing these HFCs and properly disposing of them is
considered to be one of the most import ant climate actions the world can
take.

e) Water Vapor : The most abundant greenhouse gas overall, water
vapor differs from other greenhouse gases in that changes in its
atmospheric concentrations are linked not to human activities directly, but
rather to the warming that results from the other greenhouse gases we
emit. Warmer air holds more water. And since water vapor is a greenhouse
gas, more water absorbs more heat, inducing even greater warming and
perpe tuating a positive feedback loop. (It’s worth noting, however, that the
net impact of this feedback loop is still uncertain , as increased water vapor
also increases cloud cover that reflects the sun’s energy away from the
earth.)

6.3.2 Causes
Population size, economic activity, lifestyle, energy use, land use patterns,
technology, and climate policy: According to the Intergovernmental Panel
on Climate Change (IPCC), these are the broad forcing s that drive nearly
all human -caused greenhouse gas emissions. Here’s a closer look at
greenhouse gas emissions by source.

a) Electricity and Heat Production : The burning of coal, oil, and natural
gas to produce electricity and heat accounts for one-quarter of worldwide
human -driven emissions, making it the largest single source. In the United
States it’s the second -largest (behind transportation), responsible for
about 27.5 percent of U.S. emissions in 2017, with carbon dioxide the
primary gas released (along with small amounts of methane and nitrous
oxide), mainly from coal combus tion.

b) Agriculture and Land Use Changes: About another quarter of global
greenhouse gas emissions stem from agriculture and other land -use
activities (such as deforestation). In the United States, agricultural
activities —primarily the raising of livestock and crops for food —
accounted for 8.4 percent of greenhouse gas emissions in 2017. Of those,
the vast majority were methane (which is produced as manure decomposes
and as beef and dairy cows belch and pass gas) and nitrous oxide (often
released with the use of nitrogen -heavy fertilizers).

Trees, plants, and soil absorb carbon dioxide from the air. The plants and
trees do it via photosynthesis (a process by which they turn carbon dioxide
into glucose); the soil houses microbes that carbon binds to. So
nonagricultural land -use changes such as deforestation, reforestation
(replanting in existing forested areas), and afforestation (creating new
forested areas) can either increase the amount of carbon in th e atmosphere
(as in the case of deforestation) or decrease it via absorption, removing
more carbon dioxide from the air than they emit. (When trees or plants are munotes.in

Page 95

Supplementary An alytical
Tools and Environmental
Issues - II
95 cut down, they no longer absorb carbon dioxide, and when they are burned
or decompose, they re lease carbon dioxide back into the atmosphere .) In
the United States, land -use activities currently represent a net carbon sink ,
absorbing more carbon dioxide from the air than they emit.

c) Industry : About one-fifth of global human -driven emissions come
from the industrial sector, which includes the manufacturing of goods and
raw materials (like cement and steel), food processing, and construction.
In 2017, industry accounted for 22.4 percent of U.S. man -made emissions,
of which the majority was carbon dioxide, though methane, nitrous oxide,
and fluorinated gases were also released.

d) Transportation : The burning of petroleum -based fuels, namely
gasoline and diesel, to power the world’s transportation systems accounts
for 14 percent of global greenhouse g as emissions. In the United States,
with Americans buying larger cars and taking more flights and with low
gas prices encouraging drivers to use their cars more, transportation is the
largest contributor of greenhouse gases. (It accounted for 28.7 percent of
U.S. emissions in 2017.) Carbon dioxide is the primary gas emitted,
though fuel combustion also releases small amounts of methane and
nitrous oxide, and vehicle air conditioning and refrigerated transport
release fluorinated gases too.

Nationwide, cars and trucks are responsible for more than 80 percent of
transportation -related carbon emissions.

e) Buildings Operating buildings around the world generates 6.4
percent of global greenhou se gases. In the United States, homes and
businesses accounted for about 11 percent of warming emissions. These
emissions, made up mostly of car bon dioxide and methane, stem primarily
from burning natural gas and oil for heating and cooking, though other
sources include managing waste and wastewater and leaking refrigerants
from air -conditioning and refrigeration systems.

f) Other Sources : This c ategory includes emissions from energy -related
activities other than fossil fuel combustion, such as the extraction,
refining, processing, and transportation of oil, gas, and coal. Globally, this
sector accounts for 9.6 percent of emissions .

6.3.3 The Consequences of the Greenhouse Effect
Today’s human -caused greenhouse gas emissions are higher than ever , the
concentration of greenhouse gases in the atmosphere is rising rapidly, and
according to the IPCC, the planet is heating up. Between preindustrial
times and now, the earth’s average temperature has increased 1.8 degrees
Fahrenheit ( 1.0 degrees Celsius ), with approximately two-thirds of that
warming occurring in the last handful of decades alone. According to the
IPCC, 1983 to 2012 was likely the warmest 30 -year period of the last
1,400 years (in the Northern Hemisphere, where assessment is possible).
And all five of the years from 2014 to 2018 were the hottest on munotes.in

Page 96

Environmental Economics
96 record globally. If warming trends continue at the current rate, it’s
estimated global warming will reach 2.7 degrees Fahrenheit ( 1.5 d egrees
Celsius) above preindustrial levels between 2030 and 2052.

Fueled by man -made greenhouse gas emissions, global warming
is altering the earth’s climate systems in many w ays. It is:

 Causing more frequent and/or intense extreme weather events,
including heat waves , hurricanes , droughts , and floods .
 Exacerbating precipitation extremes , making wet regions wetter and
dry regions drier.
 Raising sea levels due to melting glaciers and sea ice and an increase
in ocean temperatur es (warmer water expands, which can contribute to
sea level rise).
 Altering ecosystems and natural habitat , shifting the geographic
ranges, seasonal activities, migration pa tterns, and abundance of land,
freshwater, and marine species.
These changes pose threats not only to plants and wildlife, but directly to
people. Warmer temperatures mean insects that spread diseases like
dengue fever and Zika can thrive —and heat waves ar e getting hotter and
more lethal to humans . People could go hungry when our food supply is
diminished thanks to droughts and floods —a 2011 National Research
Council study found that for every degree Celsius that the planet heats
up, crop yields will go down 5 to 15 percent. Food insecurity can lead
to mass human migration and political instability. And in January 2019,
the Department of Defense released a report that described the threats to
U.S. military installations and operations around the world due to
flooding, droughts, and other impacts of climate change.

6.3 GLOBAL WARNING AND CLIMATE CHANGE
Global warming is the slow increase in the average temperature of the
earth’s atmosphere because an increased amount of the energy (heat)
striking the earth from the sun is being trapped in the atmosphere and not
radiated out into space.

The earth’s atmosphere has always acted like a greenhouse to capture the
sun’s heat, ensuring that the earth has enjoyed temperatures that permitted
the emergence of life forms as we know them, including humans.

Without our atmospheric gre enhouse the earth would be very cold. Global
warming, however, is the equivalent of a greenhouse with high efficiency
reflective glass installed the wrong way around.

Global warming is a phenomenon of climate change characterized by a
general increase in a verage temperatures of the Earth, which modifies the
weather balances and ecosystems for a long time. It is directly linked to munotes.in

Page 97

Supplementary An alytical
Tools and Environmental
Issues - II
97 the increase of greenhouse gases in our atmosphere, worsening the
greenhouse effect.

6.3.1. Causes Of Global Warming:
Global warming is the extra heat within the earth’s atmosphere which has
caused the rise in global temperature. Global warming leads and continues
to cause climate change. Climate change can cause rising sea levels,
destruction of communities, as well as extreme weather conditions.

1. Oil and Gas
Oil and Gas is used all the time in almost every industry. It is used the
most in vehicles, buildings, production and to produce electricity. When
we burn coal, oil and gases it largely adds to the climate problem. The us e
of fossil fuels is also a threat to wildlife and the surrounding
environments, because of the toxicity it kills off plant life and leaves areas
uninhabitable.The massive use of fossil fuels as burning coal, oil and gas
produces carbon dioxide - the most important greenhouse gas in the
atmosphere - as well as nitrous oxide causes global warning.

2. Deforestation
Deforestation is the clearance of woodland and forest, this is either done
for the wood or to create space for farms or ranches. Trees and forest s turn
carbon dioxide into oxygen, so when they are cleared like the stored
carbon is then released into the environment. Deforestation can also occur
naturally which has a greater effect because of the fumes released from the
fire.The exploitation of fore sts has a major role in climate change. Trees
help regulate the climate by absorbing CO 2 from the atmosphere. When
they are cut down, this positive effect is lost and the carbon stored in the
trees is released into the atmosphere.

3. Waste / WASTE DISPOSAL
Humans create more waste now than ever before, because of the amount
of packaging used and the short life cycle of products. A lot of items,
waste and packaging isn't recyclable, which means it ends up in landfills.
When the waste in landfills begins to d ecompose/break down it releases
harmful gases into the atmosphere which contribute to global
warming. Waste management methods like landfills and incineration emit
greenhouse and toxic gases - including methane - that are released into the
atmosphere, soil and waterways, contributing to the increase of the
greenhouse effect.

4. Power Plants
Power plants burn fossil fuels to operate, due to this they produce a variety
of different pollutants. The pollution they produce not only ends up in the
atmosphere but also in the water ways, this largely contributes to global
warming. Burning coal which is used in power plants is responsible for
around 46% of total carbon emissions.


munotes.in

Page 98

Environmental Economics
98 5. Oil Drilling
Oil drilling is responsible for 30% of the methane population and around
8% carbon dioxide pollution. Oil drilling is used to collect petroleum oil
hydrocarbons in this process other gases are released into the atmosphere,
which contribute to climate chang e, it is also toxic to the wildlife and
environment it surrounds.

6. Transport and Vehicles
The large amount of transportation is done through cars, planes, boats and
trains, almost all of which rely on fossil fuels to run. Burning fossil fuels
releases c arbon and other types of pollutants into the atmosphere. This
makes transportation partly responsible for the greenhouse gases. This
effect could be reduced with the introduction of electric vehicles.

7. Consumerism
Due to the innovations in technology an d manufacturing customers are
able to purchase any product at any time. This means we are producing
more and more products every year, and over producing them. Most items
we purchase aren't very sustainable, and because of the reduced lifetime of
electroni cs and clothing items, we are creating more waste than
ever.Overconsumption also plays a major role in climate change. In fact, it
is responsible for the overexploitation of natural resources and emissions
from international freight transport, which both c ontribute to global
warming.

8. Farming
Farming takes up a lot of green space meaning local environments can be
destroyed to create space for farming. These animals produce a lot of
greenhouse gases for example methane, as well as this they also produce
an extreme amount of waste. Factory farming is responsible for even more
climate issues because of the extra pollution it produces and the more
animals it can hold.intensive farming, not only with the ever -increasing
livestock, but also with plant protection products and fertilizers. In fact,
cattle and sheep produce large amounts of methane when digesting their
food, while fertilizers produce nitrous oxide emissions.

9. Industrialization
Industrialisation is harmful in a variety of ways. The waste this indu stry
produces all ends up in landfills, or in our surrounding environment. The
chemicals and materials used within industrialisation can not only pollute
the atmosphere but also the soil underneath it.

10. Overfishing
Fish is one of humans main sources of protein and a lot of the world now
rely on this industry. Due to the amount of people buying and consuming
fish, there is now a reduced amount of marine life. Overfishing has also
caused a lack of diversity within the ocean.


munotes.in

99 11. MINING
Modern life is hig hly dependent on the mining and metallurgical industry.
Metals and minerals are the raw materials used in the construction,
transportation and manufacturing of goods. From extraction to delivery,
this market accounts for 5% of all greenhouse gas emission.

6.3.2. Global warming effects

1. On biodiversity
The increase of temperatures and the climate upheavals disturb the
ecosystems, modify the conditions and cycles of plant reproduction. The
scarcity of resources and climate change are changing life habits and
migratory cycles of animals. We are already witnessing the disappearance
of many species - including endemic species - or, conversely, the intrusion
of invasive species that threaten crops and other animals.
Global warming therefore impacts biodiversit y. It is the balance of
biodiversity that is modified and threatened. According to the IPCC, a
1.5°C (34.7°F) average rise might put 20 -30% of species at risk of
extinction. If the planet warms by more than 2°C, most ecosystems will
struggle.

2. On oceans
Because of global warming, permafrost and ice are melting massively at
the poles, increasing the sea level at a rate never known before. In a
century, the increase reached 18 cm (including 6 cm in the last 20 years).
The worst case scenario is a rise of up to 1m by 2100.

The acidification of the oceans is also of great concern. In fact, the large
amount of CO 2 captured by the oceans makes them more acidic, arousing
serious questions about the adaptability of seashells or coral reefs.

3. On humans
Human bein gs are not spared by these upheavals. Climate change is
affecting the global economy. It is already shaking up social, health and
geopolitical balances in many parts of the world. The scarcity of resources
like food and energy gives rise to new conflicts.

Rising sea levels and floods are causing population migration. Small
island states are in the front line. The estimated number of climate
refugees by 2050 is 250 million people.

4. On the weather
For decades now, meteorologists and climatologists around th e world have
been watching the effects of global warming on the weather phenomena.
And the impact is huge: more droughts and heatwaves, more
precipitations, more natural disasters like floods, hurricanes, storms and
wildfires, frost -free season, etc.

100 6.3.3. Global Warming Prevention:
Good news - there are ways to reduce global warming. But how to react to
climate change? What solutions to consider?

1. Renewable energies
The first way to prevent climate change is to move away from fossil fuels.
What are the alternatives? Renewable energies like solar, wind, biomass
and geothermal.

2. Energy & water efficiency
Producing clean energy is essential, but reducing our consumption of
energy and water by using more efficient devices (e.g. LED light bulbs,
innovative shower systems) is less costly and equally important.

3. Sustainable transportation
Promoting public transportation, carpooling, but also electric
and hydrogen mobility , can definitely help reduce CO 2 emissions and
thus fight global warming.

4. Sustainable infrastructure
In order to reduce the CO 2 emissions from buildings - caused by heating,
air conditioning, hot water or lighting - it is necessary both to build new
low energy buildings, an d to renovate the existing constructions.

5. Sustainable agriculture & forest management
Encouraging better use of natural resources, stopping massive
deforestation as well as making agriculture greener and more efficient
should also be a priority.

6. Responsible consumption & recycling
Adopting responsible consumption habits is crucial, be it regarding food
(particularly meat), clothing, cosmetics or cleaning products. Last but not
least, recycling is an absolute necessity for dealing with waste.

6.5. QUESTIONS:
1. Define air pollution. What are the causes of air pollution?
2. Define water pollution. What are the causes of water pollution?
3. Define noise pollution. What are the causes of noise pollution?
4. Explain the effects of air, water and noise pollution.
5. Explain in brief the measures taken to control air, water and noise
pollution.
6. Write an explanatory note on Ozone Layer Depletion.
7. Write an explanatory note on Global Warmin g and Climate Change.

7.1 INTRODUCTION
Environmental economics is a sub -field of economics that is concerned
with environmental issues. It has become a widely studied topic due to munotes.in

Page 102

Environmental Economics
102 growing concerns in regards to the environment in the twenty first century.
Quoting from the National Bureau of Economic Research Environmental
Economics program:
Environmental Economics undertakes theoretical or empirical studies of
the economic effects of national or local environmental policies around the
world. Particular issues include the costs and benefits of alternative
environmental policies to deal with ai r pollution, water quality, toxic
substances, solid waste, and global warming.
Environmental economics is distinguished from ecological economics in
that ecological economics emphasizes the economy as a subsystem of the
ecosystem with its focus upon preserving natural capital. One survey of
German economists found that ecological and environmental economics
are different schools of economic thought , with ecological economists
emphasizing "strong" sustainability and rejecting the proposit ion that
natural capital can be substituted by human -made capital.
Environmental economics is a sub discipline of economics focusing on the
inter-relationships between the environment and the economy. It explains
how the concept of economic efficiency in t he allocation of scarce
resources
Environmental economics is the subset of economics that is concerned
with the efficient allocation of environmental resources. The environment
provides both a direct value as well as raw material intended for economic
activity, thus making the environment and the economy interdependent.
For that reason, the way in which the economy is managed has an impact
on the environment, which, in turn, affects both welfare and the
performance of the economy.
7.2 ENVIRONMENTAL POLICY
Environmental policy can include laws and policies addressing water
and air pollution, chemical and oil spills, smog , drinking water quality,
land conservation and management, and wildlife protection, such as the
protection of endangered species . Environmental policy , any measure by
a government or corporation or other public or private organization
regarding the effects of human activities on the environment, particularly
those measures that are designed to prevent or reduce harmful effects of
human activities on ecosystems.
Environmental policies are needed because environmental values are
usually not considered in organizational decision -making. There are two
main reasons for that omission. First, environmental effects are economic
externalities. Polluters do not usually bear the consequences of their
actions; the negative effects most often occur elsewhere or in the future.
Second, natural resources are usually underpriced because they are often
assumed to have infinite availability. Together, th ose factors result in what
American ecologist Garrett Hardin in 1968 called “the tragedy of the
commons.” The pool of natural resources can be considered as a commons munotes.in

Page 103

Environmental Policy and
Practices - I
103 that everyone can use to their own benefit. For an individual, it is rational
to use a co mmon resource without considering its limitations, but that self -
interested behaviour will lead to the depletion of the shared limited
resource —and that is not in anyone’s interest. Individuals do so
nevertheless because they reap the benefits in the short term, but
the community pays the costs of depletion in the long term. Since
incentives for individuals to use the commons sustainably are weak,
government has a role in the protection of the commons.

7.3 ENVIRONMENTAL POLICY INSTRUMENTS
Numerous instruments have been developed to influence the behaviour of
actors who contribute to environmental problems. Traditionally, public
policy theories have focused on regulation, financial incentives, and
information as the tools of government. However, new policy instruments
such as performance requirements and tradable permits have been used.
7.3.1 Regulation
Regulation is used to impose minimum requirements for environmental
quality. Such interventions aim to encourage or discourage specific
activities and their effects, involving particular emissions, particular inputs
into the environment (such as specific hazardous substances), ambient
concentrations of chemicals, risks and damages, and exposure. Often,
permits have to be acquired for those activities , and the permits have to be
renewed periodically. In many cases, local and regional governments are
the issuing and controlling authorities. However, more -specialized or
potentially hazardous activities, such as industrial plants treating
dangerous chemic al substances or nuclear power stations using radioactive
fuel rods, are more likely to be controlled by a federal or national
authority. munotes.in

Page 104

Environmental Economics
104 Regulation is an effective means to prescribe and control behaviour.
Detailed environmental regulations have resulted in a considerable
improvement in the quality of air, water, and land since the early 1970s.
The strengths of regulation are that it is generally binding —it includes all
actors who want to undertake an activity described in the regulation —and
it treats them in the same framework. Regulations are also rigid: they are
difficult to change. That can be considered as a strength, since rigidity
ensures that regulations will not change too suddenly. However, rigidity
can also be considered a weakness, because it sl ows down innovation, as
actors seek to stay within the letter of the law rather than creating new
technologies, such as more -efficient emission scrubbers on smokestacks
that would remove more pollution than what the regulation mandates.
When regulations de mand standards that are difficult or impossible to
meet —because of a lack of knowledge, skills, or finances on the part of
the actors or mismanagement by policymakers —regulations will not be
effective.
One common improvement in environmental regulation mad e since the
1970s has been the development of performance requirements, which
allow actors to determine their own course of action to meet the standard.
For example, they are not required to purchase a particular piece of
equipment to meet an emissions sta ndard. They can do it another way,
such as developing a technology or process that reduces emissions. The
advantage of performance requirements is that actors addressed by the
regulation are encouraged to innovate in order to meet the requirements.
Despite that advantage, performance requirements cannot keep actors who
lack incentives from achieving more than the minimum requirements.
7.3.2 Financial incentives
Governments can decide to stimulate behavioral change by giving positive
or negative financial in centives —for example, through subsidies, tax
discounts, or fines and levies. Such incentives can play an important role
in boosting innovation and in the diffusion and adoption of innovations.
For example, in Germany the widespread subsidizing of solar
energy systems for private homeowners increased the large -scale adoption
of photovoltaic (PV) panels. Financial incentives or disincentives can also
stimulate professional actors to change. A potential drawback of financial
incentives is that they distort the market. When not used for a limited
period, they can make receivers dependent upon the subsidy. A final
drawback is that subsidies are expensive instruments, especially when they
are open -ended.
7.4 ENVIRONMENTAL REPORTING AND ECO -
LABELING
Several instrum ents aim to inform decision makers about the
environmental effects of their actions. Decisions are usually based on
a cost-benefit analysis of which environmental costs and benefits are not
part. The environmental impact assessment (EIA) is an instrument t hat
helps public decision makers to decide on initiatives with a certain munotes.in

Page 105

Environmental Policy and
Practices - I
105 environmental impact, such as the construction of roads and industrial
plants. The EIA, which has become a legal requirement in many countries,
requires that the environmental effects of a project, such as the building of
a dam or shopping mall, be studied and that the actors be informed of how
to mitigate environmental damage and what compensation they could
receive for doing so. EIAs allow decision makers to include environmental
information in a cost -benefit analysis. Although all EIAs cannot stop
initiatives from taking place, they can reduce the negative environmental
impacts.
Environmental management systems are comprehensive approaches that
help organizations reduce their use o f natural resources while reducing
costs and —when certified —contributing to a positive image. The most
commonly known standard for such systems is the ISO 14000 standards,
first issued by the International Organization for Standardization (ISO) in
1996. Su ch standards help an organization control its environmental
impact, formulate and monitor environmental objectives, and demonstrate
that they have been achieved.
Ecolabels and certificates applied to specific products and services inform
consumers about th eir environmental performance. Sometimes
governments require such labels and certificates, such as the “EU
Ecolabel” marking in Europe, which certifies that a product has met
minimum requirements for consumer safety, health, and environmental
friendliness. To push organizations to develop products and services that
perform beyond those minimum requirements, there are labels that
specifically express the environmental friendliness of the product or
service. For example, the Energy Star rating in the United S tates indicates
the energy performance level of household appliances. Ecolabels are often
applied in the food industry (such as for certified organic or fair-
trade certified products) and for energy performance in buildings (LEED
standards). The underlying assumption of ecolabeling is that informed
consumers buying environmentally responsible products will stimulate
industry to innovate and produce cleaner products.
7.5 GLOBAL POLICY AGREEMENTS
From the early 1970s, the United Nations (UN) has provided the main
forum for international negotiations and agreements on environmental
policies and objectives. The 1972 Stockholm conference was the first
international conference on environmental issues and was followed by
the United Nations Conference on Environment and Development
(UNCED) summits in Rio de Janeiro in 1992 and in Johannesburg in
2002. The UN also hosted special conferences on climate change, such as
those of 1996 in Kyoto and 2009 in Copenhagen.
Those conferences and summits responded to the global character of some
of the most -challenging environmental problems, which would require
international cooperation to solve. Those conferences were effective in
setting an international agenda for regional and national environmental
policy making that resulte d in treaties and protocols, also known as “hard munotes.in

Page 106

Environmental Economics
106 law,” and in nonbinding resolutions, statements, and declarations, or “soft
law.” Whereas the 1992 Rio conference agreement was a soft law,
the Kyoto Protocol was a hard law, with clear -cut reduction targets
of greenhouse gas emissions for regions and countries. Nation -states, in
their efforts to meet the targets, could make use of three so -called
flexibility mechanisms designed to lower the costs of compliance.
Joint implementation, the first mechanism, allo wed countries to invest in
lowering emissions in other countries that had ratified the
Kyoto Protocol and, thus, had a reduction target to meet. For
industrialized, developed countries that had already invested in emission
reductions in their own economies , it was cheaper to invest in emission
reductions in other countries with economies in transition, where the same
investment would lead to greater reductions. In other words, the investing
country could get credit for helping a country with an economy in
transition to lower its emissions.
Clean development, the second mechanism, allowed industrialized
countries that have ratified the protocol to meet their targets in any country
where it is cheapest to invest —that is, in developing countries —even if
that co untry did not ratify the protocol. That mechanism is not undisputed,
since it involves questions of intervention in the economies of developing
countries, which may have an impact on the economic development of
those countries. To prevent industrialized co untries from not reducing
their own emissions, the mechanism can only be used in supplement to
domestic reductions, but no definition of such supplemental action was
given, which led some countries to achieve 50 percent of their reduction
target through th at mechanism.
The third mechanism, carbon -emission trading (which is also known as
“cap and trade”), is a market -based instrument and can be applied in the
form of voluntary markets or in a mandatory framework. Most trading
schemes are based on a cap -and-trade model. A central authority puts a
cap on the overall carbon emissions allowed in a country or region. Within
that cap, emission rights are allocated to the polluters, and emissions
produced beyond those rights are penalized. The idea is that polluters
choose between investing in emission reductions or emission permits. By
lowering the cap over time, total emission reduction can be achieved. The
trade of permits will ensure that emissions reduction is achieved at the
lowest costs.
How emissions trading works ?Assume two emitting plants, A and B.
Each plant emits 100 tons of pollutants (for a total emission of 200 tons),
and the requirement is that these emissions be cut in half, for an overall
reduction of 100 tons.(Left). In a traditional command -and-
controlsystem, each plant might be required to reduce by 50 percent, or
50 tons, to meet the overall reduction of 100 tons. Plant A might be able to
reduce at only $100 a ton, for a total expenditure of $5,000. Plant B might
have to spend $200 a ton, for a t otal of $10,000. The cost for both plants to
reach the overall reduction of 100 tons would therefore be $15,000.(Right)
In a cap -and-trade system, each plant might be given allowances for only munotes.in

Page 107

Environmental Policy and
Practices - I
107 half its previous emissions. Plant A, where reduction costs onl y $100 a
ton, might be able to reduce emissions to as little as 25 tons, leaving it
with unused allowances for 25 tons of pollutants that it is not emitting.
Plant B, where reduction costs $200 a ton, might find it less costly to
reduce to only 75 tons and then buy Plant A's unused allowances,
effectively paying Plant A to make the 25 tons of reductions that Plant B
cannot afford. The overall reduction of 100 tons would still be reached but
at a lower overall cost ($12,500) than under the command -and-contro l
system.
The instrument of tradable permits has been applied to other emissions.
The first emission -trading schemes date back to 1974, when the United
States experimented with emissions trading as part of the Clean Air Act.
7.6 POLICY INSTRUMENTS
Policy makers can call upon on an array of mechanisms in support
of environmental policy (Figure 7.1. The main categories of policy
instruments are regulation (command -and-control),market -based
(economic) instruments (MBIs), voluntary approaches, and education
and information. The approaches are not mutually exclusive: all rely to
some extent on education and information provision, which is signified
in Figure 7.1 by the central placement of this category. For example,
voluntary approaches include self-regulation, while economic instruments
might be underpinned by regulation.

Figure 7.1. Policy instruments.
In concert with the changing nature of environmental governance
generally, the balance in the use of these instruments is changing from
what was once a predominant reliance on regulatory methods to a much
greater resort to market -based and voluntary approaches. Accordingly,
greater responsibility is being transferred to the individual, either directly munotes.in

Page 108

Environmental Economics
108 through the market as an instrument of policy or throu gh policy
prescriptions that individualize the responsibility for the environment.
In most nations, environmental policy has historically relied on the use of
public regulation, which is often associated with command -and-control
instruments, such as zoning , discharge standards, licensing, bans or limits
on inputs and outputs, and requirements in terms of technology and
design. Despite their widespread use, regulatory measures are considered
by some people to be inflexible, intrusive, and inefficient; in man y cases,
they have failed to change behaviour with respect to the environment.
Accordingly, in recent years, there has been a trend in many Western
nations toward self -regulation, in which private interests (such as farmers,
companies, and individuals), ra ther than governments, regulate to protect
the public good. Examples of private -interest regulatory mechanisms
include industry codes of practice, environmental certification, eco -
labelling programs and agreements between interest groups and industry.
Ther e is a growing interest in quality control codes and certification
systems, particularly in manufacturing, agriculture, and food processing
industries. Although there is no legal enforcement, governments can
influence the design, implementation, and impact of private regulation in a
variety of ways. Thus, governments are showing interest in a greater
reliance on self -regulation and voluntary standards, together with a
statutory duty of care for the environment, on the basis that everyone who
could influence the risk of environmental harm should be required to take
all reasonable and practical steps to prevent any foreseeable harm from
their actions. This is an important shift in the approach to policy
implementation.
An emphasis on the development of volunta ry or partnership programs
involving individuals and community groups undertaking local projects
for environmental remediation have accompanied the progressive shift of
responsibility to individuals, firms, and communities. The strategies of
partnerships, self-help, and community empowerment have been used to
encourage participation and to promote the idea that environmental
problems are best addressed through communities working together and
with government and industry. Advantages might include increased public
participation in decision making, which is now sometimes associated with
what is called ‘deliberative democracy’. A wide range of concerns
counterbalances the positive rhetoric surrounding partnerships and civic
environmentalism, however. These refe r to the implications of imbalances
of power in partnerships, volunteer burnout in community -based
programs, an absence of strategic direction in terms of environmental
outcomes, and a lack of adequate resources.
To overcome the limitations of both volunta ry and regulatory approaches,
there has been an increasing interest in, and acceptance of, the use of
economic instruments in support of environmental policy objectives.
These market -like mechanisms aim to internalize negative environmental
externalities, for example, by creating markets in carbon, biodiversity, and
salinity. Economic instruments provide financial incentives/disincentives
that, in many cases, are likely to engender better responses to munotes.in

Practices - I
109 environmental issues, while avoiding the complexities an d prescriptive
nature of legislation.
Although the enthusiasm for economic instruments is widespread, they
have also been subject to critical assessment. There are equity issues and
prospective operational problems arising from the definition of property
rights and organizational capacity. A review of the use of economic
instruments in the Organisation for Economic Co -operation and
Development (OECD) nations revealed ‘no black and white picture of
their general success’.
The success of policy instruments re lies on matching them to the
particular ecological, political, and economic situation and to the
capabilities of institutions and stakeholders. It is not necessarily a matter
of developing new tools and instruments, but designing a ‘mix’ of policy
instrume nts that is best suited to the circumstance. It has also been
established that the attitudes and outlook of stakeholders (e.g., industry,
individuals, and land managers) are fundamental considerations in
bringing about changes in environmental practices. T o succeed, new
policy approaches require the cooperation of these stakeholders.
Thus, the effective and efficient implementation of policy and
management strategies by government relies, in part, on an understanding
of what stakeholders regard as the key issues that influence those
decisions that in turn impact on the environment, how they are responding
to these issues, their disposition toward various policy and management
tools, and their past experience in working with government agencies. The
main func tion of environmental policy is to, through government action,
minimize the environmental impact of businesses and society .
A therapeutic approach in which efforts are directed either toward
reducing external pressures (e.g., employment or financial problems)
that contribute to emotional difficulties or toward modifying aspects of the
individual's living or working space to improve functioning.
Policy makers who seek to improve environmental quality (or the
management of natural resources) have a numb er of policy approaches
that they can use. These include command -and-control regulations,
market -based instruments (such as taxes and cap -and-trade
programs) , and voluntary approaches.
7.7 THE COMMAND -AND -CONTROL APPROACH
The principle is to command people or firms not to do something by
enacting a law that makes it illegal and by delegating authorities to enforce
such law through the imposition of fines or penalty to violators.
7.7.1 Command -and-control approach and environment standards
Command -and-control approach (CAC) is one where political authorities
mandate people, by enacting a law, to bring about a behavior and use an
enforcement machinery to get people to obey the law. In environmental munotes.in

Page 110

Environmental Economics
110 policy, the CAC approach involves the settin g of standards to protect or
improve environmental quality. A standard is generally the tool used in the
CAC approach.
It is a mandated level of performance enforced through a piece of
legislation. A few examples are the limits set on the volume of timber that
could be harvested, bans on the cutting of trees, and maximum levels
legally allowed for pollution emissions. There are three types of
environmental quality standards, namely, ambient, emission and
technology.
7.7.2 Ambient standards.
These refer t o "never -exceed" levels for some pollutants in a particular
environment. The Philippine Clean Air Act, which repeals the National
Pollution Control Act, for instance, establishes ambient air quality
standards for source -specific air pollutants such as sulf ur oxide and carbon
monoxide from mobile and stationary sources. For water quality,
meanwhile, the ambient standards refer to minimum levels needed to be
maintained for dissolved oxygen, pH or acidity level, biochemical oxygen
demand (BOD), and total colif orm organisms, etc. Dropping beyond this
minimum level would lead to a harmful situation. And while ambient
standards cannot be directly enforced, legal measures could nonetheless be
imposed on polluters to regulate their emission -producing activities.
7.7.3 Emission standards.
Emission or effluent standards are also "never -exceed" levels applied
directly to the quantities of emissions from pollution sources per unit of
time. For example, the Philippine Clean Air Act of 1999 allows maximum
emission of s pecific pollutants from vehicles. The Act also allows the
Department of Environment and Natural Resources (DENR) to designate
each regional industrial center to allocate emission quotas within its
jurisdiction. In effect, emission standards set a limit or constraint to the
level of performance that has to be observed by the polluters, as highway
speed limit does. Since emission standard only sets the maximum limit of
emission, however, the polluters are left with the decision on how to
achieve it. Setting e mission standards does not necessarily mean meeting
ambient standards. Even if emission standards are imposed on firms but no
control on the number of polluting firms is established, then the aggregate
environment quality in terms of ambient standards is n ot directly checked.
The recent phenomenon in Bolinao, Pangasinan illustrates this point as the
unabated proliferation of fish pens and cages caused the accumulation of
fish feeds and other wastes in the water. This then reduced the dissolved
oxygen conte nt, eventually resulting in fish kill.
7.7.4 Technology standards
These standards specify the technologies or practices, including design,
engineering, input and output standards, that polluters must adopt or meet
to protect the environment. In contrast to emission standards, technology munotes.in

Page 111

Environmental Policy and
Practices - I
111 standards impose on polluters certain decisions and technologies to be
used. This is some form of "technology forcing" for polluting industries to
adopt technological change in order to meet environment standards.
7.8 CONCERNS ON ENVIRONMENT STANDARDS
Standards are popular because they appear simple and specific in targets.
However, in reality, there are complications and other considerations that
have to be addressed such as the level of standards, uniformity of
standard s, equity effects and enforcement. While standards under the CAC
approach may appear to directly put restraints on pollution, it has a
number of limitations, particularly in the incentive it offers polluters to
comply with environment standards. CAC is lik e a "one -size-fits-all"
approach (World Bank 1999) that does not categorically consider varying
performance of polluters, thereby ignoring the efficiency principle. This
constraint has thus encouraged the use of other policy alternatives for
environmental management, one of which is the "polluter pays" principle.
This is an incentive -based strategy where taxes or charges are estimated
according to the level of emission. The incentive system adopted by the
Laguna Lake Development Authority (LLDA) in the 199 0s illustrates how
it restored the lake that has become a basin of industrial wastes from
surrounding industries. The LLDA imposed a charge per unit of emission
within the legally permissible standard and a higher unit charge for
emissions above the standa rd. In two years' time, the scheme brought
about an 88 percent reduction in BOD discharges from the pilot plants
covered in the initial implementation (World Bank 1999).
7.9 VOLUNTARY APPROACHES FOR
ENVIRONMENTAL POLICY: ENVIRONMENTAL
EFFECTIVENESS, ECONOM IC EFFICIENCY AND
USAGE IN POLICY MIXES
Voluntary actions by firms and households to improve environmental
performance clearly should be welcomed − and there is a considerable
literature indicating that firms can profit from taking such voluntary
action. H owever, opinions differ concerning the usefulness for policy
makers to rely on voluntary approaches to achieve environmental targets.
Voluntary approaches include agreements on environmental performance
negotiated with industry and public programs in which firms can volunteer
to participate. Some see such approaches as offering a chance to address
environmental problems in a flexible manner at a low cost, based on
consensus building between the different stakeholders. Others believe that
such approaches pro vide few environmental improvements beyond what
would have occurred anyway, and that both administrative and abatement
costs can be greater than with other instruments.
The report “Voluntary Approaches for Environmental Policy” provides an
up-to-date discu ssion of the use of such approaches in meeting
environmental policy goals. It builds on a number of case studies, and munotes.in

Page 112

Environmental Economics
112 focuses in particular on the environmental effectiveness, economic
efficiency and the administrative costs related to these approaches − when
they are used either in isolation or as part of “policy mixes” together with
other types of policy instruments.
The report demonstrates that a large, and seemingly increasing, number of
voluntary approaches is being used in environmental policy in OECD
member countries, most often in combination with one or more other
instruments. While recognizing that it would be imprudent to make overly
generalized statements about the merits of applying voluntary approaches,
a few conclusions can be drawn:
 While the environmental targets of most − but not all − voluntary
approaches seem to have been met, there are only few cases where
such approaches have been found to contribute to environmental
improvements significantly different from what would have happened
anyw ay.
 Hence, the environmental effectiveness of voluntary approaches is still
questionable.
 This could indicate that a significant degree of “regulatory capture”
has taken place.
But it remains unclear what would have been the − realistic − alternative
to a given policy or policy combination. Would there in practice have been
sufficient political willingness to give priority to reach ambitious
environmental targets − if that, for instance, could jeopardize the (often
modest) employment in the most affected (h ighly polluting) sectors?
The broadening use of voluntary approaches seems to reflect the fact that
policymakers have tried to find an instrument through which one could
avoid having to make such trade -offs. It is, however, unlikely that difficult
trade -offs can be avoided if more ambitious environmental targets are to
be met in the future.
 In most member countries, the entry into force of the Kyoto protocol
will represent a new situation, where they face an economy -wide,
legally binding, environmental target. If, under such a regi me, some
sectors are given a more lenient treatment, other sectors will have to
abate more − or the country will have to buy more quotas in the
international market.
 Voluntary approaches are generally designed to limit the impacts of
environmental policie s on the production costs of participating firms.
However, when firms do not face an appropriate marginal incentive to
abate pollution (from a tax, or from the value of a tradable emission
permit), environmental policy largely fails to stimulate a reductio n in
demand for the products that cause environmental problems in their
production. munotes.in

Page 113

Environmental Policy and
Practices - I
113  The economic efficiency of voluntary approaches is generally low − as
they seldom incorporate mechanisms to equalize marginal abatement
costs between all producers, inter a lia because environmental targets
tend to be set for individual firms or sectors, rather than at a national
level.
 However, traditional “command and control” policies also rarely
equalize abatement costs at the margin between different polluters, and
volun tary approaches can offer a higher economic efficiency than such
policies, by providing increased flexibility in how environmental
improvements are to be accomplished.
 Voluntary approaches can sometimes be put in place more rapidly than
alternative policy instruments, like new regulations or economic
instruments. However, the likelihood of a voluntary approach
providing any environmental improvements beyond “Business -as-
Usual” depends strongly on their quality.
A “first best” approach would be to replace t he “command and control”
policies by economy -wide economic instruments − taxes or tradable
permits − where technically and administratively possible.
A “second -best” option could be to improve the flexibility of pre -existing
“command and -control” regulati ons, instead of a piece -meal approach that
lets only a few companies attain environmental improvements in a more
flexible manner.
The performance of many voluntary approaches would be improved if
there were a real threat of other instruments being used if (appropriately
set) targets are not met. However, if it is likely − or widely believed − that
the alternative policy would entail significant negative social impacts, the
credibility of such threats may not be great.
Various types of administrative and tra nsaction costs vary greatly between
different voluntary approaches. If too few resources are spent in their
preparation, negotiation and enforcement, their environmental impacts are
likely to be very modest.
Combining a voluntary approach with a tax or a tradable permit system
can trigger quite significant additional administrative costs, and the
environmental integrity of the other instrument can be weakened.
Based on the discussion in the report, some recommendations for policy
formulation have been sing led-out:
Consider carefully if current environmental targets − or the lack of such
targets − represent a reasonable balance between the combined benefits of
additional environmental improvements and the total costs of achieving
such improvements.
• Consid er also if the targets are set in such a way that they encompass as
many as possible of the sources of a given problem. munotes.in

Page 114

Environmental Economics
114 If economic costs under current policies are allowed to be higher than
what could have been possible, in order to limit social costs (e. g.
concerning transitory unemployment and/or impacts on low -income
households): consider carefully whether other policy instruments cannot
better address such social concerns.
 If a voluntary approach is already applied: consider whether target
fulfilment t o date is satisfactory, and whether credible threats of the
application of additional instruments would be appropriate − and
possible to implement.
 If a new voluntary approach is being prepared: elaborate first a
“Business -as-Usual scenario”, describing li kely developments in the
years ahead if no policy -changes were to be made. Quantified targets
should be set with reference to this scenario, in such a way that
marginal abatement costs and marginal benefits of the environmental
improvements balance reasona bly well. Consider carefully whether
well-prepared alternative policy instruments − that could serve as
credible threats − can underpin the voluntary approach. Make sure to
collect the information necessary for a later evaluation of the approach
in questio n.
 Consider carefully various potential impacts of combining a voluntary
approach with other policy instruments: ¾ Which are the likely
consequences on environmental effectiveness, economic efficiency,
administrative costs, sectoral competitiveness impacts , of the other
policy instrument(s)? ¾ Which are the likely consequences of
“adding” other instruments to the voluntary approach?
The report does not alter the finding of many previous analyses that
economy -wide economic instruments in many cases can be a better policy
option than voluntary approaches, both from the point of view of
environmental effectiveness and economic efficiency. A broader
application of economic instruments is, however, frequently hampered by
− in particular − a fear of loss of intern ational competitiveness of the most
affected (and most polluting) sectors, which in turn could have negative
impacts on employment in these sectors. Providing tax exemptions to the
sectors in questions in return for “voluntary” abatement commitments can
be one way to overcome “the competitiveness obstacle”. However, the
environmental and/or economic costs of applying this option could be
high. Increased international co -operation to facilitate use of economic
instruments would seem to be a better option.
Local incentives are the most effective approach to environmental policy.
Local governments often have a more direct knowledge of factors that
affect the environment, such as how much waste residents create or how
much water and electricity they use.
Comma nd-and-control policies regulate behavior directly , whereas
market -based policies provide incentives for private decision -makers to
change their behavior. munotes.in

Page 115

Environmental Policy and
Practices - I
115 Regulatory approaches require government agencies to restrict or direct
the activities of regulated p arties using terms and conditions within
statutory and regulatory instruments, operating permits, licenses,
approvals or codes of practice. These may be specified for a whole sector
or for an industrial process that is used across several sectors.
Regulatory approaches range widely. Some are very restrictive tools that
provide little flexibility, with government dictating the behaviour for
regulated parties to comply with environmental regulations. In contrast,
innovative regulatory approaches allow parties more latitude in selecting
the best means to comply with rules. Regulatory approaches are highly
dependent on deterrents and, as a result, effective enforcement is essential
to their success in achieving environmental goals.
7.10 ENVIRONMENTAL STA NDARDS
Environmental standards are administrative regulations or civil law
rules implemented for the treatment and maintenance of the
environment . Environmental standards should preserve nature and the
environment, protect against damage, and repair past d amage caused by
human activity.
Environmental standards are typically set by government and can include
prohibition of specific activities, mandating the frequency and methods of
monitoring, and requiring permits for the use of land or water. Standards
differ depending on the type of environmental activity.
Environmental standards may be used produce quantifiable and
enforceable laws that promote environmental protection. The basis for the
standards is determined by scientific opinions from varying discipli nes,
the views of the general population, and social context. As a result, the
process of determining and implementing the standards is complex and is
usually set within legal, administrative or private contexts.
The human environment is distinct from the natural environment. The
concept of the human environment considers that humans are permanently
interlinked with their surroundings, which are not just the natural elements
(air, water, and soil), but also culture, communication, co -operation, and
institut ions. Environmental standards should preserve nature and the
environment, protect against damage, and repair past damage caused by
human activity.
7.10.1 Development of Environmental Standards
Historically, the development of environmental standards was influenced
by two competing ideologies: eco-centrism and anthropocentrism. Eco -
centrism frames the environment as having an intrinsic value divorced
from the human utility, while anthropocentrism frames the environment as
only having value if it helps huma nity survive. This has led to problems in
establishing standards. munotes.in

Page 116

Environmental Economics
116 In recent decades, the popularity and awareness of environmentalism has
increased with the threat of global warming becoming more alarming than
ever since the IPCC released their report in 2 018. The report asserts that
based on scientific evidence “if human activities continue to at this rate it
is predicted to increase in -between 1.5 -2 °C over pre industrial levels in -
between 2030 and 2052”. Busby argues that Climate change will define
this century and that it is no longer a faraway threat. In turn, the demand
for protecting the environment has risen. Developments in science have
been fundamental for the setting of environmental standards. Improved
measurements and techniques have allowed sci entists to better understand
the impact of human -caused environmental damage on human health and
the biodiversity, which composes the natural environment.
Therefore, environmental standards in modern times are set with the view
that humans do have obligati ons toward the environment, but they can be
justified in terms of obligations toward other humans. This means it is
possible to value the environment without discarding anthropocentrism.
Sometimes called prudential or enlightened anthropocentrism. This is
evident as environmental standards often characterize the desired state
(e.g. the pH of a lake should be between 6.5 and 7.5) or limit alterations
(e.g., no more than 50% of the natural forest may be damaged). Statistical
methods are used to determine the specific states and limits the
enforceable environmental standard.
Penalties and other procedures for dealing with regions out of compliance
with the standard may be part of the legislations.
7.10.2 Governmental Institutions setting Environmental Standard s
Many different institutions set environmental standards.
United Nations (UN)
The UN, with 193 member states, is the largest intergovernmental
organization. The environmental policy of the UN has a huge impact on
the setting of international environmental standards. At the Earth
summit in 1992, held in Rio, the member states acknowledged their
negative impact on the environment for the first time. During this and the
following Millennium Declaration, the first development goals for
environmental issues wer e set.
Since then, the risk of the catastrophe caused by extreme weather has been
enhanced by the overuse of natural resources and global warming. At
the Paris Agreement in 2015, the UN determined 17 Goals for sustainable
development. Besides the fight against gl obal poverty, the main focus of
the goals is the preservation of our planet. These goals set a baseline for
global environmentalism.
The environmental areas of water, energy, oceans, ecosystems, sustainable
production, consumer behaviour and climate prote ction were covered by
the goals. The goals contained explanations on which mediums were
required to reach them. Implementation and follow -up are controlled by munotes.in

Page 117

Environmental Policy and
Practices - I
117 non-enforceable voluntary national reviews. The main control is done by
statistical values, which are called indicators . These indicators deliver
information if the goals are reached.
European Union
Within the Treaty on the Functioning of the European Union, the Union
integrates a self -commitment towards the environment. In Title XX,
Article 191.1, it is settled: “Union policy on the environment shall
contribute to the pursuit of the following objectives: — preserving,
protecting and improving the quality of the environment, —
protecting human health, — prudent and rational utilization of natural
resou rces, — promoting measures at international level to deal with
regional or worldwide environmental; problems, and in particular
combating climate change.” All environmental actions are based on this
article and lead to a suite of environmental laws. Europe an environmental
regulation covers air, biotechnological, chemical, climate
change, environmental economics, health, industry and technology, land
use, nature and biodiversity, noise, protection of the ozone layer, soil,
sustainable development, waste, and water.
The European Environment Agency (EEA) consults the member states
about environmental issues, including standards. The environmental
standards set by European legislation include precise parametric
concentrations of pollutants and also includes targ et environmental
concentrations to be achieved by specific dates.
United States
In the United States, the development of standards is decentralized. More
than a hundred different institutions, many of which are private, developed
these standards. The metho d of handling environmental standards is a
partly fragmented plural system, which is mainly affected by the market.
Under the Trump Administration, Climate standards have increasingly
become a site of conflict in the politics of global warming.
7.11 AMBIE NT AIR QUALITY STANDARDS
The National Ambient Air Quality Standards (NAAQS) are set by
the Environmental Protection Agency (EPA) to regulate pollutants in the
air. The enforcement of these standards is designed to prevent further
degradation of air quality .
States may set their own ambient standards, so long as they are lower than
the national standard. The NAAQS regulates the six criteria for air
pollutants: sulphur dioxide (SO 2), particulate matter (PM 10), carbon
monoxide (CO), ozone (O3), nitrogen dioxid e (NO 2), and lead (Pb). To
ensure that the ambient standards are met, the EPA uses the Federal
Reference Method (FRM) and Federal Equivalent Method (FEM) systems
to measure the number of pollutants in the air and check that they are
within the legal limits . munotes.in

Page 118

Environmental Economics
118 7.11.1 Air emission standards
Emission standards are national regulations managed by the EPA [ that
control the amount and concentration of pollutants that can be released
into the atmosphere to maintain air quality, human health, and regulate the
release of greenhouse gases such as carbon dioxide (CO 2), oxides of
nitrogen and oxides of sulphur.
The standards are established in two phases to stay up -to-date, with final
projections aiming to collectively save Americans $1.7 trillion in fuel
costs and reduce the amount of greenhouse gas emissions (GHG) by 6
billion metric tons. Similar to the ambient standards, individuals states
may also tighten regulations. For example, California set their own
emissions standards through the California Air Resources Board (CARB),
and these standards have been adopted by some other states. Emission
standards also regulate the number of pollutants released by heavy
industry and for electricity.
The technological standards set by the EPA do not necessarily enforce the
use of specific technologies, but set minimum performance levels for
different industries. https://en.wikipedia.org/wiki/Environmental_standard
- cite_note -:0-28 The EPA often encourages technological improvement
by setting standards that are not achievable with current technologies.
These standards are always set based on the industry's top performers to
promote the overall improvement of the industry as a whole.
7.12 IMPACT OF NON -GOVERNMENTAL
ORGANISATIONS ON ENVIRONMENTAL
STANDARDS
7.12.1 International Organization of Standardization
The International Organization of Standardization (ISO) develops a large
number of voluntary standards. With 163 member states, it has a
comprehensive outreach. The standards set by the ISO were often
transmitted into national standards by different nations. About 363,000
companies and organizations worldwide have the ISO 14001 certificate, a
standard for environmental management created to improve the
environmental performance of an organization and legal aspects as well as
reaching environmental aims. Most of the national and international
environmental management standards include the ISO 14000 series. In
light of the UN Sustainable De velopment Goals, ISO has identified
several families of standards which help meet SDG 13 which is focused
on Climate Action for global warming.
7.12.2 Greenpeace
Greenpeace is a popular non -governmental organization that deals with
biodiversity and the en vironment. Their activities have had a great global
impact on environmental issues. Greenpeace encourages public attention
and enforces governments or companies to adapt and set environmental munotes.in

Page 119

Environmental Policy and
Practices - I
119 standards through activities recording special environmental iss ues. Their
main focus is on forests, the sea, climate change, and toxic chemicals. For
example, the organization set a standard about toxic chemicals together
with the textiles sector, creating the concept 2020, which plans to banish
all toxic chemicals fr om textile production by 2020.
7.12.3 World Wildlife Fund
The World Wide Fund is an international non -governmental
organization founded in 1961 that works in the field of wilderness
preservation and the reduction of human impact on the environment.
7.12.4 Economy
Environmental standards in the economy are set through external
motivation. First, companies need to fulfil the environmental law of the
countries in which they operate. Moreover, environmental standards are
based on voluntary self -commitme nt which means companies implement
standards for their business. These standards should exceed the level of the
requirements of governmental regulations. If companies set further -
reaching standards, they try to fulfil the wishes of stakeholders.
At the pro cess of setting environmental standards, three different
stakeholders have the main influence. The first stakeholder,
the government , is the strongest determinate, followed by the influence of
the customers. Nowadays, there is an increasing number of peopl e, who
consider environmental factors during their purchasing decision. The third
stakeholder who forces companies to set environmental standards
is industrial participants . If companies are part of industrial networks,
they are forced to fulfil the codes of conduct of these networks. This code
of conduct is often set to improve the collective reputation of an industry.
Another driving force of industry participants could be a reaction to a
competitors action.
The environmental standards set by companies th emselves can be divided
into two dimensions: operational environmental policies and the message
sent in advertising and public communications.
7.13 OPERATIONAL ENVIRONMENTAL POLICIES
This can be the environmental management, audits, controls, or
technologies. In this dimension, the regulations tend to be closely
connected with other function areas, e.g. lean production. Furthermore, it
could be understood that multinational companies tend to set cross -
country harmonized environmental government re gulations and therefore
reach a higher performance level of environmental standards.
It is often argued that companies focus on the second dimension: the
message sent in advertising and public communications. To satisfy the
stakeholders' requirement, compa nies were focused on the public
impression of their environmental self -commitment standards. Often the
real implementation does not play an important role. munotes.in

Page 120

Environmental Economics
120 A lot of companies settle the responsibility for the implementation of low -
budget departments. The w orkers, who were in charge of the standards
missing time and financial resources to guarantee a real implementation.
Furthermore, within the implementation, goal conflicts arise. The biggest
concern of companies is that environmental protection is more exp ansive
compared to the gained beneficial effects. But, there are a lot of positive
cost-benefit -calculation for environmental standards set by companies
themselves. It is observed that companies often set environmental
standards after a public crisis. Some times environmental standards were
already set by companies to avoid public crises. As to whether
environmental self -commitment standards are effective, is controversial.
7.14 TECHNOLOGY SPECIFICATIONS
Technology specifications prescribe a particular tech nology or equipment
that a regulated party must use to control emissions/effluent levels. The
requirement or standard is typically applied to all parties within a sector
without freedom to choose alternate means of control. Specifications are
most often us ed in pollution control technology.
Where are they used?
Explicit technology specifications in environmental regulation, for
example through approvals, permits or Codes, are quite rare across most
jurisdictions. This approach works best where there is a single applicable
technology or where the need for certaint y in environmental control is
immediate, and administrative ease is desirable. When Alberta
Environment sets Sulphur recovery levels, there may only be one
commercially available technology. While the department’s Sulphur
recovery guideline does not specif y a required technology, its use is
implied and this represents a “de facto” technology specification.
Approvals issued by the department may mention the technology for
clarity purposes.
Tool performance:
Pros
 Provides a high level of certainty that the desired performance will be
achieved, assuming the operation and maintenance of the technology is
continued.
 Compliance is straightforward as it is focused on whether the specific
technology or equipment is installed and operating to specifications.
 Treats all entities within a sector equally, when applied uniformly.
 Relatively simple for the department to administer. Emissions
standards do not have to be set, and the regulator does not need to
consider the adequacy of alternative technologies propos ed by the
regulated parties. munotes.in

Page 121

Environmental Policy and
Practices - I
121 Cons
 • Specified technologies may not be adequate to achieve long -term
outcomes.
 Regulated parties cannot pursue other control technologies or methods
that might be less costly.
 Can fail to consider the different circumstanc e of each effected
regulated party.
 Requires specific operating standards and monitoring to ensure the
specified technology is being used and maintained appropriately.
 Discourages innovation amongst those firms that already are proactive
and innovative i n applying the best available technologies to enhance
environmental performance.

8.1 INTRODUCTION : MARKET BASED
INSTRUMENTS (MBI’s)
Governments need to choose policy instruments to implement their
environmental policies and to achieve environmental goals. For that
purpose, they may use traditional command -and-control approaches, but munotes.in

Page 123

Environmental Policy and
Practices - II
123 they may also c hoose to use market -based instruments as a more efficient
or more acceptable approach to meeting their objectives. In practice, it is
not about making a choice between regulatory and market -based
instruments, but rather finding a good mix between these two approaches.
Market -based instruments (MBIs) are taxes, charges, levies, tradable
permit schemes , deposit refund systems, subsidies etc. The term “market -
based environmental policy instruments” (MBIs) is used to describe a very
wide range of policy instrum ents. Their common characteristic is the use
of market power and competition to achieve environmental objectives.
Policy Design Circle

Figure 8.1
Governments can use a range of environmental policy instruments to
implement their environmental policies and deliver their commitments to
international environmental agreements. Environmental policy instruments
can roughly be divid ed into three broad categories : 1. Regulatory/
administrative instruments (so called “commandand -control”). These are
regulations, directives, bans, permits, etc., which are prescriptive and
provide the private sector with relatively little flexibility in achieving their
goals. 2. Market -based instruments (MBIs) are taxes, charges, levies,
tradable permit schemes, deposit refund syste ms, subsidies etc. These
instruments can be used to provide producers and consumers with
incentives to change their behaviour towards more efficient use of natural
resources by reducing consumption, and to look for more effective ways
of making environment al progress while giving them flexibility in how
they do so. Market -based instruments can be implemented in a systematic
manner, across an economy or region, across economic sectors, or by
environmental medium (e.g. water)
munotes.in

Page 124

Environmenta l Economics
124 8.1.1 VOLUN TARY AGREEMENTS AND INFORMATION
STRATEGIES/ MORAL SUASION :
These are voluntary environmental measures independent of government
requirement, such as bilateral agreements between the government and
private firms and voluntary commitments made by firms, e.g.
implementation of environmental management systems, publishing
environmental reports. Voluntary changes in behaviour could be
accomplished also via education, transfer of knowledge, training,
persuasion, etc.
Market -based instruments (MBIs), also referred to as “market -based
economic instruments” or “economic instruments” (EIs), are tools for
governments to implement environmental policy. These tools “affect
estimates of the costs and benefits of alternative actions open to economic
agents” Or, to put it more simply, if a to ol affects the cost or price of
goods and services in the market, then it is a market -based economic
instrument. This definition focuses on the economic signals and incentives
the instrument provides. If it changes the cost or price of a good (e.g.,
plasti c bag), service (e.g., waste collection), activity (e.g., waste dumping),
input (e.g., materials), or output (e.g., pollution) then it is a market -based
instrument.

on EEA 2005A)
munotes.in

Page 125

Environmental Policy and
Practices - II
125 8.1.2 HOW DO THEY WORK?
MBIs help to assign “the right price ” to resources that are not otherwise
appropriately valued in the market, such as water, clean air, ecosystem
services, biodiversity, and marine resources. “Getting the price right”
means that it properly reflects the resource cost or cost of the pollution
impacts and reflects the principle of “ full-cost recovery ” or the “user pays
principle”. This provides producers and consumers with incentives to
change their behaviour and look for more effectiv e ways of making
environmental progress, while giving them flexibility in how they do so.
Some MBIs through raising prices also result in revenue raising. Price
based instruments (taxes/charges, subsidies, deposit refund systems, feed -
in-tariffs, etc.) are used to lever behavioural change by changing prices in
existing markets.
Quantity based instruments (tradable permits/emissions trading schemes)
influence behavioural change by specifying the ‘amount’ of new
rights/obligations and allowing the market to set their price. Whether by
influencing prices (through taxation or incentives), or setting absolute
quantities (emissions trading), or quantities per unit of output (emission
charges), MBIs implicitly acknowledge that firms differ from each other
and ther efore provide flexibility that can substantially reduce the costs of
environmental improvements. In theory, if properly designed and
implemented, market -based instruments will allow any desired level of
pollution clean up to be realized at the lowest overa ll cost to society, by
providing incentives for the greatest reductions in pollution by those firms
that can achieve these reductions most cheaply.
8.1.3 MAIN PRINCIPLES IN USING MBIS
1. Environmental effectiveness
The most important point to underline is that any environmentally related
MBI should cause change in consumption or production pattern which will
lead to reduce environmental burden. If an instrument fails to do that, it
should be considered whether to cha nge or even abandon the instrument.
2. Economic efficiency
One of the advantages of MBIs is their effectiveness on every unit of
pollution. Taxes encourage both static (abatement at the lowest -cost
source) and dynamic (continuous reduction of pollution aba tement costs
and pollution levels) efficiency gains.
3. Equity / income distribution
Policy makers need to consider the impact of such taxes also on sensitive
groups such as low -income households or pollution -intensive, trade -
exposed businesses. Lower tax r ates or exemptions are sometimes put into
place to limit impacts on such groups. Generally it is advised not to make
exemptions into tax system itself, but rather use other policy instrument to
overcome the distributional problems. munotes.in

Page 126

Environmenta l Economics
126 4. Competitiveness
The ai m of economic instruments (especially taxes) is to make activities
with higher environmental impact less profitable in an economic sense. It
means that, at the enterprise level, there are always companies that are
better off than others – those who pollute less or are more efficient in their
resource use. The competitiveness issue rises more sharply at a sector or
national level, where taxes or tradable allowance schemes imposed may
have a negative impact on international competitiveness (if the instrument
is implemented only at local/national level).
5. Acceptance, stakeholder involvement.
The acceptance of environmental taxes is in good correlation with
awareness about environmental problems in society. Opposition to
environmental taxes may be caused by not enough information about the
purpose of the tax, little trust of assurances in how the revenue is used,
fear of loss of competitiveness or other reasons. Well -designed taxes are
highly transparent in terms of their coverage and costs. It should be clear
what is taxed, which polluters are exempt, and what the cost to polluters
will be per unit of pollution generated.
An evaluation should take place to assess which groups are most powerful,
and what their primary goal is. Allocation of rights in the baseline is also
quite important: groups with existing rights, whether actual or implied,
will often have more power/interest in fighting changes to existing
policies. The factional analysis should also assess what options exist for
buffering any social impacts that may occur from the policy reform,
especially those that affect the poor.
8.1.4 HOW DO MBI S COMPARE WITH REGULATORY
INSTRUMENTS?
As set out above, using MBIs to achieve environmental goals can be cost -
efficient20. MBIs improve price signals so that producers and consumers
can properly take them into account and are incentivised to red uce
negative - and increase positive - environmental and other impacts.
Regulatory instruments require detailed information on regulated
industries and industrial technologies in order to set standards. Command -
and-control tools often require sophisticated regulatory compliance staff.
By comparison, with MBIs the government can avoid the need for detailed
information if the market sets prices, for example for tradable permits. In
some cases, MBIs can help substitute for weak institutions in
circumstances wh ere the parties who buy rights monitor cheating on a
decentralized level - so long as sanctions can be taken against cheaters
once detected. In short, compared to regulatory instruments, market -based
instruments may offer the following advantages:
 They imp rove price signals, by giving a value to the external costs and
benefits of economic activities, so that economic actors take them into
account and change their behaviour to reduce negative – and increase
positive - environmental and other impacts . munotes.in

Page 127

Environmental Policy and
Practices - II
127  They a llow industries to have greater flexibility in meeting objectives
and thus lower overall compliance costs.
Homogenous taxes encourage abatement at the lowest -cost source, helping
to ensure that environmental goals are achieved at the lowest social cost
(“static efficiency”). Different firms face different pollution abatement
costs. By implementing a tax on emissions, for example, it will pay certain
firms more than others to cut back on emissions. This lowest -cost solution
is unlikely to be achieved if a u niform environmental standard was applied
to every individual polluter.
In contrast to regulatory instruments, the use of MBIs gives polluters
(firms) an incentive to go further and reduce pollution more than required
by environmental authorities. In the longer term, polluters may pursue
technological innovation to reduce further adverse impacts on the
environment (“dynamic efficiency”). MBIs generate revenues which could
be used for different reasons, such as providing support for innovation or
reducing o ther taxes to support employment, i.e. when used in the context
of environmental tax or fiscal reforms .
8.1.5 MAIN CONCERNS ABOUT USING MBIS
However, although there are many successful examples of using MBIs,
there are studies indicating that MBIs are not always the best instruments
for achieving change in behaviour. There are various reasons or situations
where MBIs may not succeed and regulatory and other instruments might
be more successful in achieving the objectives:
8.1.5.1 Emergency conditions .
When problems have severe implications, emergency conditions arise, and
behaviour needs to stop immediately, direct bans may be more
appropriate.
8.1.5.2 Excessive monitoring costs.
When there are a large number of very small transactions (e.g., emissio ns
trades) monitoring costs may be very high so regulations may be a better
fit.
8.1.5.3 Fragmented authorities .
Where authority to set and enforce regulations is highly fragmented across
institutions, oversight of market -based instruments might become q uite
difficult.
8.1.5.4 Equity/distributional issues.
Increasing prices to cover their full resource cost will impact on consumer
groups where they cannot switch to alternative goods and services, and
this may be of concern where they are sensitive grou ps such as low -
income households.
munotes.in

Page 128

Environmenta l Economics
128 8.1.5.5 Illegal activities .
MBIs can encourage cost -avoiding damaging activities, such as illegal
waste dumping.
8.1.5.6 Strong opposition.
Where political power and interest group factions remain strong, policy
makers need to judge the most prudent course.
8.1.5.7 High level of dislocation.
Where large numbers of people will be displaced or unemployed as a
result of MBIs, caution is required.
8.1.5 .8 No ability to make transitional payments to affected sectors .
From a n economic perspective, it is more efficient to remove broad -based
subsidies and replace them with direct payments to the poor. Examples
include transitional subsidies to water, energy, and foodstuffs for the poor
segment of society. However, in corrupt so cieties, the transfer payments to
the poor are unlikely to actually occur. Thus, monitoring and enforcement
are essential to avoid widespread hardship or social unrest.
8.1.5 .9 International competitiveness.
Taxes on industrial inputs increase the costs of production. If the domestic
production competes with the foreign producers (without the tax) then it
may harm the competitiveness of domestic firms. The advantages and
disadvantages of the individual types of MBIs are addressed further
below.
8.1.6 MAIN TYPES OF MBIS
MBIs can be classified in different ways, for example, according to their
sector of implementation (e.g. transport, energy) or by environmental
medium (e.g. water, air). Alternatively, the European Environmental
Agency (EEA) has classif ied MBIs into five main types based on their aim
and functioning:
1. Environmental taxes (also environmentally related taxes) that have
been designed to change prices and thus the behaviour of producers and
consumers, as well as raise revenues.
2. Enviro nmental charges that have been designed to cover (in part or in
full) the costs of environmental services and abatement measures such as
waste water treatment and waste disposal.
3. Tradable permits that have been designed to achieve reductions in
polluti on (such as emissions of CO2 ) or use of resources (such as fish
quotas) in the most effective way through the provision of market
incentives to trade. munotes.in

Page 129

Environmental Policy and
Practices - II
129 4. Environmental subsidies and incentives that have been designed to
stimulate development of new techn ologies, to help create new markets
for environmental goods and services including technologies, to encourage
changes in consumer behaviour, and to temporarily support achieving
higher levels of environmental protection by companies.
5. Liability and compe nsation schemes that aim at ensuring adequate
compensation for any damages resulting from dangerous activities to the
environment and provide for means of prevention and reinstatement.
8.2 ENVIRONMENTAL TAXES AND CHARGES
The most common MBIs in use are environmental (or environmentally
related, green) taxes and charges. Taxes are generally considered to be
unrequited payments to (usually) national or regional governments with no
individual counterpart service received in exchange for the payment.
Charges , on the other hand, are typically payments made in exchange for a
service, with the charges usually levied in proportion to the quantum of
service received, and so the terms ‘user charges’, or ‘cost recovery
charges’ are often used in this context. Enviro nmental taxes and charges
can be based on emissions, inputs and outputs.
Environmental taxes include all environment -related taxes, excises and
state fees, which are recorded as taxes in national accounts. The base of an
environmental tax is a physical unit (or a proxy of it) of something that has
a proven specific negative imp act on the environment – pollutants or on
goods, the use of which produces such pollutants. By seeking to reduce
polluting behaviour, environmental taxes by definition are intended to
alter production decisions and to have a disproportionate impact on
polluters. Accordingly, environmental taxes can be either explicit (taxes
directly on emissions) or implicit (taxes on inputs or related goods).
Economic theory suggests that direct taxes on polluting emissions will
reduce environmental harm in the least cost ly manner, because they give
polluters an incentive to reduce their pollution up to the point where
further reduction would cost more than paying the tax, and to do so in the
least costly way. It can provide incentives for innovation. A market -based
tax pl aces no cap on pollution allowed - the amount by which producers
reduce their pollution depends on the chosen tax rate. Taxes present a
good option to manage pollution from diffuse sources, where regulatory
measures may be more complex to implement and enf orce (e.g. taxes on
fertilizers or car emissions). Taxes/charges raise revenues that may be
used for other purposes, including environmental improvement schemes.
This can increase the overall benefit from the tax and revenue policy
package.
The acceptance of environmental taxes is in good correlation with
awareness about environmental problems in society. Opposition to
environmental taxes may be caused by not enough information about the
purpose of the tax, little trust in assurances of how the revenue is used,
fear of loss of competitiveness or other reasons. Well -designed taxes munotes.in

Page 130

Environmenta l Economics
130 should be highly transparent in terms of their coverage and costs. It should
be clear what is taxed, which polluters are exempt, and what the cost to
polluters will be per unit of pollution generated.
One instrument used in relation to natural resources is royalty. A royalty
is a payment made by one party (e.g. private company) to another (e.g.
the state) that owns a particular asset (mineral resources, oil) for the
right to ongoing use of that asset. R oyalty is based on either the volume
or value of the production (often expressed as a percentage of the
revenues obtained or a fixed price per unit sold).
Royalty is not considered to be an environmental policy instrument,
because its aim is not to intern alise the externalities, change the
behaviour of producers or reduce the resource use. It is designed to
compensate the owner for the asset’s use. However, explicitly royalties
may influence the use of natural resources.
8.2.1 MAIN CONCERNS RELATED TO ENV IRONMENTAL
TAXES
Finding the proper level of taxation is critical to the effectiveness of the
instrument because it is difficult to anticipate exactly how much pollution
reduction will result from any given tax. Policy makers can be expected to
fully expl ore the factors that are likely to determine the effectiveness of
the tax, and consider the potential need to be flexible and ready to make
changes in the design of the tax, should the circumstances change. For
example increasing commodity prices could res ult in reducing the case for
taxes to raise the price.
Taxes and charges provide clear cost signals, but are less effective in
guaranteeing a given environmental outcome and hence ensuring that
targets are met or that an immediate reduction is secured to address a crisis
situation.
Taxes, such as carbon pricing, are a clear illustration of the risk for MBIs
to bring competitive disadvantage and losing market shares against
competitors that do not face a carbon price. Industries that are subject to a
climat e policy have the potential to move their production to countries
without such taxation, reducing the employment opportunities and the
economic output within the acting country. Opposition to increased
environmental taxes often focuses on concerns that fir ms might relocate
and/or people might lose their jobs.
The introduction of some taxes (e.g. carbon tax) can have a regressive
impact, as low -income households tend to spend a higher share of their
income on energy bills and energy intensive goods. In the e nd, however,
the final distributional impact of carbon pricing depends on the
government’s allocation of the revenues raised or expenditures saved
through the carbon pricing mechanisms.
Introducing a tax establishes a conflict between objectives: less pol lution
means less revenue. This means that evaluation of the tax needs to be munotes.in

131 undertaken against its direct objectives but also in the context of the wider
tax and spend policy as a whole, as part of environmental tax reform.
8.2.3 ENVIRONMENTAL SUBSIDIES
The OECD broadly defines a subsidy as “any measure that keeps prices
for consumers below market levels, or for producers above market levels,
or that reduces costs for consumers and producers”. Subsidies can come in
the form of:
 direct grants, transfers of funds that are clearly visible in some
countries’ budgets (i.e. on -budget subsidies);
 tax exemptions (which are generally less visible on government
accounts, but can be calculated, so called off -budget);
 other types that are less evident as subsidies: f or example accelerated
depreciation of environmentally preferable capital assets; and less than
full-cost recovery pricing with resources costs/the costs of externalities
not borne by the producer and not covered by the price of their goods
or services.
Beyond this there are other subsidies that are not always recognised as
such: for instance, where prices for goods and services, such as water
supply, do not reflect the full costs of provision (i.e. not full cost recovery
pricing), or do not reflect the re source costs. A further important category
is where there is no internalisation of externalities such as environmental
damage (i.e. not following the polluter pays principle).
Subsidies have traditionally been used for economic or social reasons, for
examp le to support ailing industries, to help develop vital infrastructure or
to protect domestic producers from overseas competition. They can be
seen as a way of protecting jobs, either generally or in specific regions, for
example support for fishermen to pr otect coastal fishing communities. The
use of subsidies for environmental purposes, however, is more recent, but
they are nowadays widely used by government to achieve environmental
objectives to encourage more environmentally beneficial behaviour (e.g.
introduction of better technologies).
Some subsidies are environmentally harmful. These are the subsidies/tax
exemptions etc. which confer an advantage on certain consumers, users or
producers, in order to supplement their income or lower their costs, but in
doing so, discriminate against sound environmental practice.
Subsidies are present in all sectors of the economy. The most common
areas where subsidies exist include energy and transport.
8.2.3 MAIN CONCERNS RELATED TO SUBSIDIES
Some subsidies are inefficient use of government resources – notably
where the original rationale for the subsidy is no longer applicable. munotes.in

Page 132

Environmenta l Economics
132 Some subsidies create environmental burdens – e.g. pollution and climate
effect; excessive resource use; or other im pacts such as on fisheries stock
viability, biodiversity, etc.
Environmentally harmful subsidies (EHS) lead to inefficient working of
the internal market, and overall impacts on competitiveness.
EHS can hinder innovation by locking in old technologies an d locking out
new ones and hence undermining the needed innovation developments for
a competitive and environmentally sustainable economy.
Important targets will not be met or be difficult to meet without reforming
subsidies – notably meeting CO2 reductio n targets.
“Costs” of environmentally harmful subsidies. The scale of subsidies
with potential negative impact on the environment, notably in the areas
of fossil fuels, transport and water, are estimated to be worth a global
total of USD 1 trillion. These subsidies lead to higher levels of waste,
emissions, resource extraction, or negative impact on biodiversity.
8.2.4 LIABILITY AND COMPENSATION SCHEMES
Liability and compensation have not typically been regarded as market -
based instruments. However, they do have some potentials to produce a
number of economic impacts and to affect the market, and they can
therefore be classed as economic or market -based i nstruments.
In the context of damage to the environment, the development and
enforcement of liability legislation inherently recognise the rights of the
public to environmental goods, specifically placing responsibility on the
polluter for restoring the e nvironment or compensating for environmental
damage. Most commonly known examples of such damages include
marine oil spills, nuclear damage, groundwater contamination and
impairment of ecosystems and landscapes. In addition, countries such as
Denmark and G ermany, for example, have also enforced liability laws for
non-genetically modified crops being contaminated by genetically
modified organisms (GMO).
8.3 GREEN PUBLIC PROCUREMENT
Green public procurement (GPP) is “a process whereby public authorities
seek to procure goods, services and works with a reduced environmental
impact throughout their life cycle when compared to goods, services and
works with the same primary function that would otherwise be procured”.
Implementing green criteria in purchasing i s one direct way for
governments to influence the market to provide more environmentally
friendly goods. GPP can avoid unnecessary purchases by involving a
review of the need for the product or service and the range of solutions
that best fit that need. Th rough setting required criteria for goods or
services GPP can lead to direct environmental gains through the purchase
of greener products (e.g. less CO2 emission by purchasing electricity from munotes.in

Page 133

Environmental Policy and
Practices - II
133 renewable energy sources). It can also help create a critical m ass of
demand to support the development of a wider market for ecological
products.
Possible savings by implementing GPP:
Three million tonnes of CO2 would be saved in the Netherlands alone if
all Dutch public authorities applied the national Sustainable Public
Procurement criteria, which include green criteria. Public sector energy
consumption would be reduced by 10%. CO2 emissions would be cut by
15 million tonnes per year if the whole European Union adopted the
same environmental criteria for lighting a nd office equipment as the
City of Turku, Finland – reducing electricity consumption by 50%.
8.4 LABELLING SCHEMES
As set out in the introduction, lack of information may also lead to market
failure. In these circumstances governments can take action to m andate or
encourage the market to provide consumers with better information. For
example, the government can create labelling schemes to provide
information on products and their environmental and health impacts from
their production and their use (e.g. or ganic farming labelling, eco -labels).
Such labels can help consumers to choose more environmentally friendly
products and services and can lead to consumption shift. Labelling
schemes can cover different product/service groups and regions (have a
look on e xamples in table 8.1).

8.5 TRADABLE PERMITS
Market -based tradable (also transferable) permits or cap -and trade
schemes set a limit on access to a resource (the cap) and then allocate it
among the users in the form of permits. Under a tradable permit system,
an allowable overall level of pollution or use of resource is established and
allocated among firms in the form of permits. Firms that keep their munotes.in

Page 134

Environmenta l Economics
134 emission levels or resource use below their allotted level may sell their
surplus permits to other firms or use them to offset excess emissions in
other parts of their business (figure 8.3)
Figure 8.3 Emissions Trading

Tradable permits have been designed to achieve reduction in pollution or
use of resources in the most effective way through the provision of market
incentives to trade. With tradable permits it is likely to achieve a
maximum set level (a cap) at a lower cost than other means, and,
importantly, may reduce below that level due to technological innovation.
The most common forms of tradable permits are: emissions trading on air
pollutants (e.g. EU ETS), emissions trading on water quality (nutrients
discharges to water courses), resource use allowances (e.g. fishing quotas,
animal allowances), etc.
In theory, different tradable permit systems are analogous. However, there
may be important d ifferences in practice between, for example, pollution
permits markets and fishing quota markets. For instance, controlling and
forecasting emissions from a power plant is arguably easier than
predicting both the level of catch on any trip and its composit ion. This is
especially true in multi -species fisheries where fish populations cannot be
directly targeted without incidental catch of other stocks.
Where regulators have a good sense of the point at which emissions
causing health problems or ecosystems b egin to fray, tradable permits are
often the best choice. Caps can be set in advance, either based on:
 absolute values (e.g., tons of salmon that can be caught or emissions
emitted) or
 relative values (e.g., percent of total allowable catch or emission). munotes.in

Page 135

Environmental Policy and
Practices - II
135  Another important aspect of tradable permits is whether they are
auctioned or allocated via free allocation/ grandfathering. There are
three main modes of allocating allowances:
 competitive auctioning
 free allocation proportionate to sources’ past emiss ion levels
 free allocation subjected to regular update based on activity levels.
Full auctioning is the most economically efficient approach as it generates
budget revenues that can, for example, be used to offset other distortionary
taxes and assist with transitional costs. However, some level of free
allocation is common practice whe n trading systems have been introduced.
This is generally done to lower direct financial cost and alleviate concerns
about international competitiveness. Within the same system, more than
one allocation mechanism can be applied, sometimes differentiated ac ross
sectors.
8.5.1 MAIN CONCERNS RELATED TO TRADABLE PERMITS
Emissions trading (ET) offers a dynamic incentive and can help ensure
that a given target is met, if combined with appropriate allocation of
emission allowances. The price of allowances is, ho wever, uncertain and
determined by the market. Therefore, the costs of pollution abatement are
uncertain, and excessive costs could be occurred.
ET can lead to significant additional administrative tasks and burdens and
greater needs for monitoring, verif ication and enforcement, the costs of
which need to be taken into account in any consideration of whether ET
schemes are the sensible solution.
An argument against permits is that formalizing emission rights is
effectively giving people a license to pollut e, and this can be considered to
be socially unacceptable. When using a transferable -permit system, it is
very important to accurately measure the initial problem and also how it
changes over time. This is because it can be expensive to make
adjustments (e ither in terms of compensation or through undermining the
property rights of the permits).
8.6 DEPOSIT REFUND SYSTEMS
A deposit -refund system (DRS), or advance deposit fee, is a surcharge on
a product when purchased and a rebate when it is returned. Deposit -refund
schemes require paying a deposit on the purchase of potentially polluting
products, which is refunded when th e products or their residues are
returned for recycling or disposal (see figure 8.4). While most commonly
used with beverage containers (packaging) it can be used on other
materials including liquid and gaseous wastes. Deposit -refund systems are
used on pr oducts such as batteries, tires, automotive oil, consumer
electronics, shipping pallets etc. munotes.in

Page 136

Environmenta l Economics
136 Figure 8.4 Deposit Refund System for Packaging
(From Consumer’s perspective)

Source: EestiPandipakend
Deposit -refund systems aim to give a financial incentive for consumers to
return the product or the waste back to retailers or producers for reuse,
recycling or disposal. Deposit -refund systems can be voluntary or
mandated by legislation.
The deposit refu nd system can have particular design features to increase
the incentive effect or adjust the cost burden. For example if the refund is
lower than the deposit, the difference can be a “handling fee” which is
passed to the recycler to make the recycling more economic (as in the
Swedish return system for aluminium cans and PET bottles). If the deposit
return is higher than the deposit this can increase the incentive to return
the item and reduce consumer resistance to the scheme where there is a
long period be tween paying the deposit and receiving the refund (as in the
earlier deposit -refund scheme for car hulks in Sweden.
8.6.1 MAIN CONCERNS RELATED TO DEPOSIT REFUND
SYSTEMS
Deposit -refund systems are considered to be more cost -effective
than other methods of reducing waste disposal (such as regulations,
subsidies), but the relatively high administrative costs of a deposit system
could outweigh these cost savings. If the DRS is implemented in one
region or country and the product is subject to export (e.g. b everages) then
domestic producers might have a competitive disadvantage compared to
foreign producers.

137 8.7 INSTRUMENTS MIXES
MBIs are seldom used individually and are often used as part of a package
of a number of MBIs or they are combined with regulatory (command -
and-control measures). The main reason for using an instrument mix is
that in most cases environmental problems are of multi -aspect nature and
no one single policy instrument can achieve the goals set alone. For
example, in order to ach ieve the goal of reducing CO 2 emissions,
governments may use explicit and implicit carbon pricing as well as create
energy efficiency standards for housing and vehicles. Using
complementary MBIs can also reinforce their incentive effects. For
example, ETS can be complemented with energy taxation. Supplementing
ETS with CO 2 taxes can help limit compliance -cost uncertainty by giving
polluters the opportunity to pay the pre -determined tax instead of buying a
tradable permit, the price of which can be rather volatile at times.
In most cases, policy mixes are not initially designed as such but rather
individual instruments are created separately and over time, new
instruments are added to address the inefficiencies of the existing policies.
For example, explici t pricing mechanisms can be complemented by
research and technology support policies to address knowledge and
diffusion failures of specific emission reduction technologies, energy
labelling to reduce information barriers, energy efficiency building codes
to address split incentives between landlords and tenants, and active
competition and regulations to limit market power.
8.8 ENVIRONMENTAL TAX / FISCAL REFORMS
Environmental (also called “ecological”, “green”) tax or fiscal reform is
not an instrument by i tself but rather a wider approach to change taxing or
fiscal system in a way which is beneficial both for the environment and
socio -economic development.
Environmental tax reform (ET R) is defined as “reform of the national tax
system where there is a shi ft of the burden of taxes, for example from
labour to environmentally damaging activities, such as unsustainable
resource use or pollution”.
Under ETR, the tax burden is shifted from ‘good’ things such as income
and employment and on to “bad” things such as pollution and resource
use. Environmental fiscal reform extends beyond ET R by including
subsidy reforms, which entail phasing out subsidies on environmentally
harmful activities and products, such as fossil fuels or pesticides, and
redirecting public s pending towards more socially and environmentally
beneficial activities.
There are at least four possible types of effects of ETR:
 it makes various goods or activities more expensive
 the direct or indirect distribution of this extra revenue
 job creation and eco -innovation munotes.in

Page 138

Environmenta l Economics
138  effective ETR will also result in environmental benefits, for example
by reducing pollution.
One of the challenges of ETR is ensuring that the costs and benefits are
appropriately distributed across society, and do not negatively impact the
poorest people. Instruments also need to balance the right mix of
environmental and economic incentives. Ultimately, ETR mechanisms can
only be implemented if they are acceptable to the public and policy
makers.
Environmental tax reform in Germa ny Between 1999 and 2003 the
German government followed a policy of ecological tax reform. It raised
taxes on consumption of environmentally damaging fossil fuel energy in
small foreseeable stages, through increased taxes on engine fuels,
electricity, ligh t fuel oil and gas. This created incentives for energy
conservation, innovative energy -efficient technologies and the use of
renewable energies. In this way, emissions of greenhouse gases and air
pollutants have been reduced and oil dependence eased.
The tax revenue collected is mainly used for a direct reduction of non -
wage labour costs by lowering employers’ and employees’ contributions
to the pension fund. A smaller part is used as support for renewable
energy and for the renovation of buildings for ene rgy saving purposes;
and tax reductions and exemptions are used to support energy -efficient
power plants and public transport amongst other things.
The ecological tax reform thus helps to support and strengthen climate
protection while labour becomes chea per and more attractive.

8.9 REHABILITATION AND RESETTLEMENT
POLICY
Government of India has formulated the National Rehabilitation &
Resettlement Policy, 2007. One of its aims is to minimize large -scale
displacement , as far as possible. The Policy also provides comprehensive
rehabilitation & resettlement benefits to the di splaced families.
The objectives of the National Rehabilitation and Resettlement Policy
are: to minimise displacement and to promote ,' as far as possible, non -
displacing or least -displacing alternatives; to ensure adequate
rehabilitation package and expedi tious' implementation of the
rehabilitation process with the active participation .
Resettlement and Rehabilitation (R&R) Plan forms a part of
the Environmental Impact Assessment and Management Plan
Reports (EIA and EMP) and is assessed and approved by the Expert
Appraisal Committee (EAC) of Ministry of Environment, Forest and munotes.in

139 Climate Change (MoEF&CC) for according Environmental Clearance to
the project.
The R&R Plan for project affected families for ongoing projects has been
prepared based on National Poli cy for Rehabilitation and Resettlement,
2003 and as per National Rehabilitation and Resettlement Policy, 2007
(NRRP -2007). For new and upcoming projects the provisions of the R&R
Plan would be according to the Right to Fair Compensation and
Transparency in Land Acquisition, Rehabilitation and Resettlement Act,
2013 and its amendments which come from time to time. The R&R Plan is
implemented in association with the concerned State Government,
representatives from project affected families and other stakehold ers in the
area. Considering the plight of those who have sacrificed their resources
for the larger benefit of the society, ways and means has to be explored
and implemented to protect their rights in general and the rights of
vulnerable sections in partic ular, as an attempt towards sustainable
developments. In the process, NEEPCO explores various viable
alternatives and select the one causing least displacement or adverse
impacts. Therefore, a detailed socio -economic survey is conducted before
formulation of R&R Plan for the project affected families (PAFs) so as to
assess the socio -economic and socio -cultural set -up of the affected
families and local people. In future, in addition to Socio -economic aspects,
a separate chapter on socio -cultural aspects base d on study on
Ethnography of the area will be included. For effective implementation &
monitoring of R&R Plan of a project, NEEPCO in consultation with the
concerned State Government forms a Project R&R Committee headed by
Administrator for R&R (rank of Di strict Collector of the concerned State
Government) and Head of the Project being the Member Secretary of the
committee.
A broad R&R package being implemented by NEEPCO at its various
projects comprises the following: -
Compensation :
 Compensation cost for land.

Page 142

Environmenta l Economics
142 8.10 THE REHABILITATION AND RESETTLEMENT
BILL, 2007
Highlights of the Bill
 The Rehabilitation and Resettlement Bill, 2007 provides for benefits
and compensation to people displaced by land acquisition purchases or
any other involuntary displacement. The Bill creates project -specific,
state and national authorities to formulate, implement, and monitor the
rehabilitation and re settlement process.
 For large scale displacement, the government shall conduct a social
impact assessment. It shall appoint an Administrator for Rehabilitation
and Resettlement who is responsible for formulating, executing, and
monitoring the rehabilitatio n and resettlement plan.
 The Bill outlines minimum benefits for displaced families and the
criteria for eligibility. Benefits may include land, house, monetary
compensation, skills training and preference for jobs.
 The Bill establishes the post of Ombudsma n to address any grievances
from the rehabilitation and resettlement process. Civil courts are
barred from entertaining any suits related to this matter.
8.10.1 KEY ISSUES AND ANALYSIS
 Though the purpose of the Bill is to ‘provide for the rehabilitation and
resettlement’ of affected persons, the Bill itself does not require that
these persons be resettled.
 While the Statement of Objects and Reasons mentions minimising
displacement, protecting livelihoods, and improving living standards,
the language in the Bill does not make these clauses mandatory.
 The affected families eligible for benefits are identified as of the date
of declaration of the affected area. This declaration is made when 400
or more families are affected en masse. It is not clear whether benefits
apply in cases where fewer families are displaced.
 The National Rehabilitation Policy, 2007 requires residency for 3
years in the affected area for displacement benefits. The Bill requires 5
years.
 The Bill bars civil courts from entertaining any suits on issues under
the authority of the Administrator, Commissioner, or Ombudsman.
These authorities are effectively given the power of a judicial authority
without judicial qualifications. There is also no mechanism for
appeals.
 The Bill does not spec ify a clear timeframe for rehabilitation. munotes.in

143 8.11 THE KYOTO PROTOCOL
The Kyoto Protocol was an international agreement that aimed to
reduce carbon dioxide (CO2) emissions and the presence of greenhouse
gases (GHG) in the atmosphere. The essential tenet of th e Kyoto Protocol
was that industrialized nations needed to lessen the amount of their CO2
emissions.
he protocol was adopted in Kyoto, Japan in 1997, when greenhouse gases
were rapidly threatening our climate, life on the earth, and the
planet. Today, the Kyoto Protocol lives on in other forms, and its issues
are still being discussed.
 The Kyoto Protocol is an international agreement that called for
industrialized nations to reduce their greenhouse gas emissions
significantly.
 Other accords, like the Doha A mendment and the Paris Climate
Agreement, have also tried to curb the global -warming crisis.
 Talks begun by the Kyoto Protocol continue in 2021 and are
extremely complicated, involving politics, money, and lack of
consensus.
 The U.S. withdrew from the agre ement on the grounds that the
mandate was unfair and would hurt the U.S. economy.
 The Paris Climate Agreement of 2015, which replaced the Kyoto
Protocol, includes commitments from all major GHG -emitting
countries to reduce their climate -altering pollution.
8.11.1 THE KYOTO PROTOCOL EXPLAINED
Background
The Kyoto Protocol mandated that industrialized nations cut their
greenhouse gas emissions at a time when the threat of global warming
was growing rapidly. The Protocol was linked to the United Nations
Framew ork Convention on Climate Change (UNFCCC). It was adopted
in Kyoto, Japan on December 11, 1997, and became international law on
February 16, 2005.
Countries that ratified the Kyoto Protocol were assigned maximum
carbon emission levels for specific periods and participated in carbon
credit trading. If a country emitted more than its assigned limit, then it
would be penalized by receiving a lower emissions limit in the following
period.
Major Tenets
Developed, industrialized countries made a promise under the Kyoto
Protocol to reduce their annual hydrocarbon emissions by an average of munotes.in

Page 144

Environmenta l Economics
144 5.2% by the year 2012. This number would represent about 29% of the
world's total greenhouse gas emissions.
Targets depended on the individual country. As a result, each natio n had a
different target to meet by that year.
Members of the European Union (EU) pledged to cut emissions by 8%,
while the U.S. and Canada promised to reduce their emissions by 7% and
6%, respectively, by 2012.
The amount of the Kyoto Protocol fund that was meant to aid developing
countries in selecting non -greenhouse -emitting industrialized processes
and technologies.
3 Kyoto Mechanisms
The Protocol established market mechanisms based on the trade of
emissions permits. It allowed countries an additional means to meet their
targets by way of three market -based mechanisms: International Emissions
Trading, Clean Development Mechanism (CDM) and Joint
Implementation (JI).
The mechanisms encouraged GHG mitigation in the most cost -effective
ways, i.e. in the de veloping world. The idea was that as long as pollution
is removed from the atmosphere, it does not matter where it is reduced,
which stimulated green investment in developing countries and included
the private sector to develop cleaner infrastructure and s ystems over older,
dirtier technology.
An Adaptation Fund was established to finance adaptation projects and
programmes in developing countries that are parties to the Protocol. In the
first commitment period, the Fund was financed mainly with a share of
proceeds from CDM project activities. For the second commitment period,
international emissions trading and joint implementation would also
provide the Fund with a 2% share of proceeds.
The International Emissions Trading mechanism allows countries that
have emission units to spare – emissions permitted them but not “used” - to
sell this excess capacity to countries that are over their targets.
The Clean Development Mechanism allows a country with an emission -
reduction or emission -limitation commitment unde r the Kyoto Protocol
(Annex B Party) to implement an emission -reduction project in
developing countries. Such projects can earn saleable certified emission
reduction (CER) credits, each equivalent to one tonne of CO2, which can
be counted towards meeting K yoto targets.
Finally, the Joint Implementation mechanism allows a country with an
emission reduction or limitation commitment under the Kyoto Protocol
(Annex B Party) to earn emission reduction units (ERUs) from an
emission -reduction or emission removal p roject in another Annex B Party,
each equivalent to one tonne of CO2, which can be counted towards
meeting its Kyoto target. munotes.in

145 8.11.2 RESPONSIBILITIES OF DEVELOPED VERSUS
DEVELOPING NATIONS
The Kyoto Protocol recognized that developed countries are principa lly
responsible for the current high levels of GHG emissions in the
atmosphere as a result of more than 150 years of industrial activity. As
such, the protocol placed a heavier burden on developed nations than
less-developed nations.
The Kyoto Protocol man dated that 37 industrialized nations plus the EU
cut their GHG emissions. Developing nations were asked to comply
voluntarily, and more than 100 developing countries, including China and
India, were exempted from the Kyoto agreement altogether.
8.11.3 A PARTICULAR FUNCTION FOR DEVELOPING
COUNTRIES
The protocol separated countries into two groups: Annex I contained
developed nations, and Non -Annex I referred to developing countries.
The protocol placed emission limitations on Annex I countries only. Non -
Annex I nations participated by investing in projects designed to lower
emissions in their countries.
For these projects, developing countries earned carbon credits, which they
could trade or sell to developed countries, allowing the developed nations
a highe r level of maximum carbon emissions for that period. In effect,
this function helped the developed countries to continue emitting GHG
vigorously.
The United States' Involvement
The United States, which had ratified the original Kyoto agreement,
dropped out of the protocol in 2001. The U.S. believed that the agreement
was unfair because it called only for industrialized nations to limit
emissions reductions, and it felt that doing so would hurt the U.S.
economy.
The Kyoto Protocol Ended in 2012, Effectively Half -Baked
Global emissions were still on the rise by 2005, the year the Kyoto
Protocol became international law —even though it was adopted in 1997.
Things seemed to go well for many countries, including those in the EU.
They planned to meet or exceed their targets under the agreement by
2011. But others continued to fall short.
The United States and China —two of the world's biggest emitters —
produced enough greenhouse gases to mitigate any of the progress made
by nations who met their targets. In fact, there was an increase of about
40% in emissions globally between 1990 and 2009.

146 The Doha Amendment Extended Kyoto Protocol to 2020
In December 2012, after the first commitment period of the Protocol
ended, parties to the Kyoto Protocol met in Doha, Qatar, to adopt an
amendment to the original Kyoto agreement. This so -called Doha
Amendment added new emission -reduction targets for the second
commitment period, 2012 –2020, for participating countries.
The Doha Amendment had a short life. In 2015, at the sustain able
development summit held in Paris, all UNFCCC participants signed yet
another pact, the Paris Climate Agreement, which effectively replaced the
Kyoto Protocol.
8.12 THE PARIS CLIMATE AGREEMENT
The Paris Climate Agreement is a landmark environmental pa ct that was
adopted by nearly every nation in 2015 to address climate change and its
negative effects. The agreement includes commitments from all major
GHG -emitting countries to cut their climate -altering pollution and to
strengthen those commitments over time.
Every five years, countries engage in the Global Stocktake, which is an
assessment of their progress under the Paris Climate Agreement.
A major directive of the deal calls for reducing global GHG emissions to
limit the earth's temperature increase i n this century to 2 degrees
(preferring a 1.5 -degree increase) Celsius above preindustrial levels. The
Paris Agreement also provides a way for developed nations to assist
developing nations in their efforts to adapt climate control, and it creates
a framew ork for monitoring and reporting countries’ climate
goals transparently.
The Kyoto Protocol Today
In 2016, when the Paris Climate Agreement went into force, the United
States was one of the principal drivers of the agreement, and President
Obama hailed it as “a tribute to American leadership.”
As a candidate for president at that time, Donald Trump criticized the
agreement as a bad deal for the American people and pledged to
withdraw the United States if elected. In 2017, then -President Trump
announced that the U.S. would withdraw from the Paris Climate
Agreement, saying that it would undermine the U.S. economy.
The former president did not begin the formal withdrawal process until
Nov. 4, 2019. The U.S. formally withdrew from the Paris Climate
Agreement on Nov. 4, 2020, the day after the 2020 presidential election,
in which Donald Trump lost his reelection bid to Joseph Biden.
On January 20, 2021, his first day in office, President Biden began the
process of rejoining the Paris Climate Agreement, which offic ially took
effect on Feb. 19, 2021. munotes.in

147 A Complicated Stalemate
In 2021, the dialogue is still alive but has turned into a complex quagmire
involving politics, money, lack of leadership, lack of consensus, and
bureaucracy. Today, despite myriad plans and some actions, solutions to
the problems of GHG emissions and global warming have not been
implemented.
Almost all scientists who study the atmosphere now believe that global
warming is primarily the result of human action. Logically then, what
humans have cause d by their behavior should be able to be remedied by
humans changing their behavior. It is frustrating to many that cohesive
action to deal with the human -made global climate crisis has yet to
happen.
8.13 REMEMBER THE INTERNET
It is critical that we rema in convinced that we can, in fact, resolve these
issues so crucial to our survival. We humans have already solved huge
problems in numerous fields via technical innovation that led to radically
new solutions.
Interestingly, if anyone had suggested in 1958 that our own Defense
Advanced Research Projects Agency (DARPA), which oversees the
development of advanced technologies for use by the U.S. military,
would lead the world in creating the Internet —a system that could
"connect every person and thing with eve ry other person and thing on the
planet instantly and at zero cost" —they might have been laughed off the
stage, or worse.
What Is the Primary Purpose of the Kyoto Protocol?
The Kyoto Protocol was an agreement among developed nations to
reduce carbon dioxid e (CO2) emissions and greenhouse gases (GHG).
Why Didn’t the U.S. Sign the Kyoto Protocol?
The United States backed out of the Kyoto Protocol agreement in 2001 on
the basis that it unfairly burdened developed nations. The treaty called
only for developed n ations to reduce emissions, which the U.S. believed
would unfairly stifle its economy.12
What Special Problems Do Developing Nations Face With Such Treaties
As the Kyoto Protocol?
Developing countries were not mandated to act under the agreement, and
volunteering to reduce emissions under it would create large costs that
they were either incapable of incurring or unwilling to incur.
What Sorts of Emissions Is the Kyoto Protocol Built to Curb?
The Kyoto Protocol was built to curb carbon dioxide (CO2) an d
greenhouse gas emissions. munotes.in

148 Important Dates of the Kyoto Protocol
December 1 -11, 1997 – The Conference of the Parties to the UNFCCC is
held in Kyoto, Japan. Nearly 200 nations attend and adopt the first
international treaty on managing and reducing greenhouse gases.
November 2, 1998 – In Buenos Aires 160 nations meet to work out details
of the protocol and create the “Buenos Aires Action Plan.”
July 23, 2001 – Negotiators from 178 countries meet in Germany and
agree to adopt the protocol, without the participation of the US.
November 10, 2001 – Representatives from 160 countries meet in
Marrakech, Morocco, to work out details of the protocol.
November 18, 2004 – The Russian Federation ratifies the protocol.
February 16, 2005 – The Kyoto Protocol comes into effect.
December 12, 2011 – Canada renounces the Kyoto Protocol, saying its
goals are unworkable because the US and China never agreed to it, and
says that a new pact is needed to address emissions.
December 2012 – The Kyoto Protocol is extended to 2020 during a
conference in Doha, Qatar.
June 23, 2013 – Afghanistan adopts the Kyoto Protocol, becoming the
192nd signatory.
2015 – At the COP21 summit, held in P aris, all UNFCCC participants sign
the Paris Agreement that effectively replaces the Kyoto Protocol. The
parties agree to limit warming to ‘well below’ 2 degrees, and below 1.5
degrees above pre -industrial levels if possible.
8.14 RIO -SUMMIT
Rio-Summit produced conventions dealing with climate change,
biodiversity, forestry and recommended a list of development practices
called Agenda 21. It gave the concept of sustainable development to be
combined economic growth with ecological responsibility .
The United Nations Conference on Environment and Development
(UNCED), also known as the Rio de Janeiro Earth Summit, the Rio
Summit, the Rio Conference, and the Earth Summit (Portuguese: ECO92),
was a major United Nations conference held in Rio de Janeiro from Ju ne 3
to June 14, 1992.
First, there has been a lack of domestic legislation to underpin the Rio
principles and conventions . Second, there was a lack of credible and
independent international scrutiny to monitor delivery.
Rio+20 was one of the biggest inter national gatherings of 2012, and the
largest event in the history of the United Nations. It presented an
opportunity to re -direct and re -energise political commitment to the munotes.in

improvement a nd environmental protection.
Agenda 21, the Rio Declaration on Environment and Development, and
the Statement of principles for the Sustainable Management of
Forests were adopted by more than 178 Governments at the United
Nations Conference on Environment and Development (UNCED) held in
Rio de Janeiro, Brazil, 3 to 14 June 1992.
The United Nations Conference on Environment and
Development (UNCED ), also known as the Rio de Janeiro Earth
Summit , the Rio Summit , the Rio Conference , and the Earth
Summit (Portug uese: ECO92), was a major United Nations conference
held in Rio de Janeiro from June 3 to June 14, 1992.
Earth Summit was created as a response for member states to cooperate
together internationally on development issues after the Cold War. Due to
issues relating to sustainability being too big for individual member states
to handle, Earth Summit was held as a platform for other member states to
collaborate. Since the creation, many others in the field of sustainability
show a similar development to the is sues discussed in these conferences,
including non-governmental organizations (NGOs).
The issues addressed included:
 systematic scrutiny of patterns of production —particularly the
production of toxic components, such as lead in gasoline, or poisonous
waste including radioactive chemicals
 alternative sources of energy to replace the use of fossil fuels which
delegates linked to global climate change
 new reliance on public transportation systems in order to reduce
vehicle emissions, congestion in cities and the health problems caused
by polluted air and smoke
 the growing usage and limited supply of water
An important achievement of the summit was an agreement on
the Climate Change Convention which in turn led to the Kyoto
Protocol and the Paris Agreement. Ano ther agreement was to "not to carry
out any activities on the lands of indigenous peoples that would
cause environmental degradation or that would be culturally
inappropriate".
The Convention on Biological Diversity was opened for signature at the
Earth Su mmit, and made a start towards redefinition of measures that did
not inherently encourage destruction of natural ecoregions and so -
called uneconomic growth.
Although President George H.W. Bush signed the Earth Summit’s
Convention on Climate, his EPA Admini strator William K. Reilly
acknowledges that U.S. goals at the conference were difficult to negotiate munotes.in

failure to sign the proposed Convention on Biological Diversity.

Twelve cities were also honoured by the Local Government Honours
Award for innovative local environmental programs. These
inclu ded Sudbury in Canada for its ambitious program to rehabilitate
environmental damage from the local mining industry, Austin in
the United States for its green building strategy, and Kitakyūshū
in Japan for incorporating an international education and tra ining
component into its municipal pollution control program.
The Earth Summit resulted in the following documents:
 Rio Declaration on Environment and Development
 Agenda 21
 Forest Principles
 Moreover, important legally binding agreements (Rio Convention)
were opened for signature:
 Convention on Biological Diversity
 Framework Convention on Climate Change (UNFCCC)
 United Nations Convention to Combat Desertification
In order to ensure compliance to the agreements at Rio (particularly
the Rio Declaration on En vironment and Development and Agenda 21),
delegates to the Earth Summit established the Commission on Sustainable
Development (CSD). In 2013, the CSD was replaced by the High -level
Political Forum on Sustainable Development that meets every year as part
of the ECOSOC meetings, and every fourth year as part of the General
Assembly meetings.
Critics point out that many of the agreements made in Rio have not been
realized regarding such fundamental issues as fighting poverty and
cleaning up the environment.
Green Cross International was founded to build upon the work of the
Summit.
The first edition of Water Quality Assessments, published by
WHO/Chapman & Hall, was launched at the Rio Global Forum.
8.15 AGENDA 21
It is the declaration signed by world leaders in 1992 at the United Nations
Conference on Environment and Development (UNCED), which took
place at Rio de Janeiro, Brazil. It aims at achieving global sustainable
development. It is an agenda that aims at fighting against environmental
damage, poverty, dis ease through global co -operation on common
interests, mutual needs and shared responsibilities. One major objective of munotes.in

Page 151

151 the Agenda 21 is that every local government should have its own local
Agenda 21 to combat environmental degradation.
The 1992 Rio Decla ration on Environment and Development defines the
rights of the people to be involved in the development of their economies,
and the responsibilities of human beings to safeguard the common
environment. The declaration builds upon the basic ideas concernin g the
attitudes of individuals and nations towards the environment and
development, first identified at the United Nations Conference on the
Human Environment (1972).
The Rio Declaration states that long term economic progress is only
ensured if it is link ed with the protection of the environment. If this is to
be achieved, then nations must establish a new global partnership
involving governments, their people and the key sectors of society.
Together human society must assemble international agreements tha t
protect the global environment with responsible development.
8.16 PRINCIPLES TO THE RIO DECLARATION.
1. People are entitled to a healthy and productive life in harmony with
nature.
2. Development today must not threaten the needs of present and future
generations.
3. Nations have the right to exploit their own resources, but without
causing environmental damage beyond their borders.
4. Environmental protection shall constitute an integral part of the
development process.
5. Eradicating poverty and reducing dispa rities in living standards in
different parts of the world are essential if we are to achieve
sustainable development whilst meeting the needs of the majority of
the people.
6. Environmental issues are best handled with the participation of all
concerned citi zens.
7. The polluter should, in principle, bear the cost of pollution.
8. Sustainable development requires better scientific understanding of the
problems. Nations should share knowledge and technologies to
achieve the goal of sustainability.
8.17 CARBON TRADI NG
Carbon trading is the process of buying and selling permits and credits that
allow the permit holder to emit carbon dioxide. It has been a central pillar
of the EU’s efforts to slow climate change. munotes.in

Page 152

Environmenta l Economics
152 Carbon trade is the buying and selling of credits that permit a company or
other entity to emit a certain amount of carbon dioxide. The carbon
credits and the carbon trade are authorized by governments with the goal
of gradually reducing overall carbon emissions and mitigating their
contribution to climate cha nge. Carbon trading is also referred to as
carbon emissions trading.
 Carbon trade agreements allow for the sale of credits to emit carbon
dioxide between nations as part of an international agreement aimed at
gradually reducing total emissions.
 The c arbon trade originated with the Kyoto Protocol, a United Nations
treaty that set the goal of reducing global carbon emissions and
mitigating climate change starting in 2005.
 Various countries and territories have started carbon trading
programs —for exam ple, in July 2021, China started a national
emissions -trading program.
 Cap and trade, a variation on carbon trade, allows for the sale of
emission credits between companies.
 These measures are aimed at reducing the effects of global warming
but their effectiveness remains a matter of debate.
 Rules for a global carbon market were established at the Glasgow
COP26 climate change conference in November 2021, enacting an
agreement first laid out at the 2015 Paris Climate Agreement.
n July 2021, China st arted a long -awaited national emissions -trading
program.1 The program will initially involve 2,225 companies in the
power sector and is designed to help the country reach its goal of
achieving carbon neutrality by 2060. It will be the world's largest carbo n
market. That made the European Union Emissions Trading System the
world's second -largest carbon trade market.2 The EU's trading market is
still considered the benchmark for carbon trading.
The carbon trade originated with the Kyoto Protocol, a United Nations
treaty that set the goal of reducing global carbon emissions and
mitigating climate change starting in 2005. At the time, the measure
devised was intended to reduce overall carbon dioxide emissions to
roughly 5% below 1990 levels by 2012. The Kyoto Protocol achieved
mixed results and an extension to its terms has not yet been ratified.
The notion is to incentivize each nation to cut back on its carbon
emissions in order to have leftover permits to sell. The bigger, wealthier
nations effectively subs idize the efforts of poorer, higher -polluting
nations by buying their credits. But over time, those wealthier nations
reduce their emissions so that they don't need to buy as many on the
market. munotes.in

Practices - II
153 When countries use fossil fuels and produce carbon dioxide, t hey do not
pay for the implications of burning those fossil fuels directly. There are
some costs that they incur, like the price of the fuel itself, but there are
other costs not included in the price of the fuel. These are known
as externalities. In the c ase of fossil fuel usage, these externalities are
often negative externalities, meaning that the consumption of the product
has negative effects on third parties.
The world’s biggest carbon trading system is the European Union
Emissions Trading System (EU ETS). It is beset with problems and
corruption and yet countries such as Brazil and China continue to pursue
carbon trading as a way to tackle rising emissions.
How do carbon trading permits work?
The model used in all current carbon trading schemes is cal led ‘cap and
trade’. In a ‘cap and trade’ scheme, a government or intergovernmental
body sets an overall legal limit on emissions (the cap) over a specific
period of time, and grants a fixed number of permits to those releasing the
emissions. A polluter mu st hold enough permits to cover the emissions it
releases. Each permit in the existing carbon trading schemes is considered
equivalent to one tonne of carbon dioxide equivalent (CO2e). In the
theoretical model, (but rarely in practice) permits are to be so ld – usually
by auction – so that from the outset, polluters are forced to put a price on
their emissions, and are incentivised to reduce to a bare minimum the
permits they seek.
8.17.1 What are offset credits?
Every current and planned carbon ‘cap and t rade’ scheme involves offset
credits in one form or another. Credits are a supplementary source of
permissions to pollute that can be bought in from countries or industries
outside the cap, usually in the developing world. Their purchase allows the
emitter to exceed the emissions cap by paying someone else somewhere
else to reduce their emissions instead. It is important to remember: offsets
do not reduce emissions, they merely replace them.
This practice of carbon offsetting has now filtered through into the realm
of private individuals, for example by paying extra money when you book
a flight to offset your carbon footprint.
8.17.2 Does carbon trading work to reduce emisions?
Carbon trading is increasingly criticised, not least because carbon dioxide
emissions in industrialised countries are not declining at the necessary rate
to avert catastrophic climate change.
Fern and many scientists, economists and NGOs believe that carbon
trading is a dangerous distraction from the need to end fossil fuel use an d
move to a low carbon future. We do not have time to wait for a high price
on carbon: we must shift to a low carbon energy, agriculture, transport and
industrial world now. The best way to do this is through direct regulation. munotes.in

Page 154

Environmenta l Economics
154 Fern’s initial interest in c arbon trading came about because trees were
seen as a way of offsetting carbon cheaply, while simultaneously
providing money to protect trees. What is Biodiversity offsetting? explains
why you can never offset carbon by protecting or planting trees. There is
also no evidence that carbon trading has lived up to the promise of
providing money.
Despite the flaws inherent in pollution trading, the concept continues to
appear in proposals to reduce environmental harm. For more information
visit our campaign on biodiversity offsetting.
