US Environmental Legislation
Environmental Protection Agency
Est.
1970
National Environmental Policy Act (NEPA)
Cornerstone
of Environmental Law
Requires Environmental Impact Statements (EIS)
for any proposed federal action
Ex:
highway or dam construction
Revolutionized
environmental protection in US
Table 2.1 in textbook provides a list

US Environmental Legislation
Numerous laws passed
since 1970
They address:
Clean
water
Clean air
Energy conservation
Hazardous waste
Pesticides
Federal regulation of
pollution

Effects of Environmental Legislation
Since 1970
Since 1990
92% of US had healthy drinking water (up from 75% in
1993)
As of 2006
wet sulfate levels decreased by 33%
As of 2008
Six air pollutants have dropped by 25% (not CO2)
45% of municipal waste is burned as waste-to-energy or
recovered for recycling
As of 2007
Human exposure to hazardous waste sites identified in
1969 is below 93%

Economics and the Environment
Economics- study of how people use limited
resources to satisfy unlimited wants
Economics is utilitarian
Goods
and services have value that can be
converted to currency
Rational Actor Model
Assumes
all individuals spend limited resources
to maximize individual utilities
Ideal economy
Resources
are allocated efficiently
© 2012 John Wiley & Sons, Inc. All rights reserved.
Optimum Amount of Pollution
Optimum Amount of Pollution
Cost
to society of having less pollution is offset by
benefits to society of activity creating pollution
Must identify
Marginal
Cost of Pollution - Cost of small
additional amount of pollution
Marginal Cost of Abatement - Cost of reducing
small amount of pollution

Economic Optimality and Pollution

Inefficiencies Arising from Different
Marginal Costs
© 2012 John Wiley & Sons, Inc. All rights reserved.
Strategies for Pollution Control
Command and Control Solutions
Government
agency requires limitations to
emissions or pollutants
Discourages development of low-cost alternatives
Incentive based Regulations
Environmental
Taxes (green taxes)
Identify
and replicate societal cost of pollution
If taxes are set at correct level private marginal cost of
pollution = social cost of pollution
Tradable
Rely
Permits
on identifying optimal level of pollution

Critiques of Environmental Economics
Difficult to assess true
costs of environmental
pollution and abatement
Impacts of pollution on
people and nature is
uncertain
Ecosystem services have no known value
Utilitarian economics may not be appropriate
Dynamic
changes and time are not considered

National Income Accounts
Estimates of National Economic Performance
and used in Politics
Gross
Domestic Product (GDP)
Net Domestic Product (NDP)
Environment may be overexploited to yield a
higher GDP in developing countries
EPI (Environmental Performance Index)
Assesses
a country’s commitment to
environmental and resource management

Environmental Justice
The right of every citizen regardless of age,
race and gender, social class or other factor, to
adequate protection from environmental
hazards
Generally, members of low income and
minority communities:
Face
more environmental threats and have fewer
environmental amenities
Have less voice in planning
© 2012 John Wiley & Sons, Inc. All rights reserved.
Environmental Justice
Challenge of environmental justice
To
find equitable solutions that respect all groups
of people
National level
1994-
Clinton required all federal agencies to
ensure their policies do not discriminate against
poor or minority communities when locating future
hazardous facilities
International level
1989-
Basal Convention (on exporting waste)

Activity:
Who is the environmentalist?
Consider the character
descriptions on the next slides.
Which of these individuals, if any,
is an environmentalist? Why?
What does this imply about
environmentalism?

MariaIs an environmental
studies major at PSU.
She is active in the
campus student
environmental group and
is trying to set up a
recycling center on
campus. She has been
saving her income from
working at a local nature
center for a trip to Costa
Rica after graduation.
Kurt- is a stock analyst
who commutes 40
minutes to his job in the
city. He carpools with
one other person in his
Suburban. Every year, he
send donations to
Greenpeace, the Sierra
Club, Willistown
Conservation Trust and
Great Valley Nature
Center. At home, his
family recycles and they
eat meat very
infrequently. They buy
locally as much as
possible.
Sasha- is an engineer at a
pulp and paper mill. She
can be heard grumbling
about the environmental
regulations her plant faces
and the gov’t agents who
come to inspect. She
recently won an award for
figuring out a way to divert
waste heat from her plant
and recycle the heat to dry
out the paper. This saves
the company $$ and
reduces energy costs.
Several years ago she won
an award for figuring out a
way to use pulp waste as
fertilizer.
Environmental Ethics
Field of ethics that considers the moral basis
of environmental responsibility
Western Worldview
Human
Deep Ecology Worldview
All
superiority and dominance over nature
species have an equal worth to humans
Most people’s ethics fall somewhere in
between

And also answer and discuss the questions on

What were the first
impacts to NSO
populations?
How did
environmentalist use
the law?
What were the
economic
consequences of the
“solution”?
What are the new
impacts to the NSO
populations?
Are these new
impacts a result of
human actions?
Is this decline just “a
part of natural
selection”? Argue
why or why not?
