US Environmental Legislation

Environmental Protection Agency
 Est.

1970
National Environmental Policy Act (NEPA)
 Cornerstone

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

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

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

economic
consequences of the
“solution”?

What are the new


Are these new
impacts a result of
