Definition – Economic Growth
• Increase in the production and
consumption of goods and services
(typically expressed in terms of GDP)
• facilitated by increasing:
–population
–per capita consumption
• Not the same as economic development

Definition – Sustainability
Sustainable development is development that meets the
needs of the present without compromising the ability of
future generations to meet their own needs.
• Basic human needs and the world’s poor
• Limits imposed by technology and social organization
- Brundtland Commission
Weak Sustainability
Hold total capital (natural
and human-built capital
combined) constant.
Assumes the two forms of
capital are substitutes.
Strong Sustainability
Hold natural capital
constant. Assumes the
two forms of capital are
complements.
Economic growth converts natural capital into human-built
capital and goods and services.

Limits on the quantity of

raw materials for the

Sink Limits
Limits on the ability of the
environment to assimilate
wastes generated by
economic production.

“If humanity wishes to preserve a planet similar to that on which civilization
developed and to which life on earth is adapted, paleoclimate evidence and
ongoing climate change suggest that CO2 will need to be reduced from its
current 385 ppm to at most 350 ppm."

Final Thought on Limits
A challenge from the realm of common sense… Can you cite
examples of Earthly things that continuously grow without
approaching a limit?
Even the biggest of the big have limits.

Alternatives
If the economy is not growing, what can it do?
(1) Shrink.
(2) Remain about the same size.

1 = recession
or state

Option
2 = steady

What is a Steady State Economy?
• Stable production and consumption of goods and
services;
• Indicated by stable GDP;
• Stabilized population;
• Stabilized per capita consumption;
• Stabilized throughput; and
• Constant stocks of natural and human-built capital.
What’s the Bottom Line?
Does a steady state economy mean…
• Freezing in the dark under a harsh communist regime?
• Some kind of hippy fantasy about returning to a
bygone era that no longer exists?
• A luddite world where we each farm our own plots of
land using nothing but sticks for tools?
A steady state economy is not a failed
growth economy. Remember the paradigm.
Characteristics of a SSE
1. Optimal Scale
2. Just Distribution
3. Efficient Allocation
4. Development and High Quality of Life
Optimal Scale
• Technical: marginal benefits of growth = marginal costs
• Conversational: Finding the sweet spot. Applying the
Goldilocks principle – not too big, not too small, just right!
A Few Elements of Sustainable Scale
• Elimination of the boom and bust cycle.
• Restoration of natural capital and ecosystem services.
• Secure stocks of natural capital.
• Maintenance and improvement of built capital.
Just Distribution
Perfectly even
distribution
Distribution with
limited inequality
A bit of a skewed
distribution
A Few Elements of Just Distribution
• Equitably assigned property rights for common resources.
• Equal access to the commons.
• Equitable distribution of common wealth.
• Limits to private income and wealth inequality.
Efficient Allocation
No market to
allocate goods
and services
Market with
stewardship of
commons
A Few Elements of Efficient Allocation
• Inclusion of non-market values.
• Evolution of sectors of the economy.
• Efficient use of capital.
Unchecked

and services
Development and Quality of Life
Poverty, illness,
and unemployment
Health, time,

Over-consumption

A Few Elements of Development and Quality of Life
• High life expectancy.
• Low infant mortality.
• Meaningful work and jobs.
• Increased leisure time.
• Green technologies and systems.

Herman Daly’s Top Ten 1-5
1. Employ cap-auction-trade systems for basic resources.
2. Institute ecological tax reform.
3. Limit the range of inequality in income distribution.
4. Shorten the working day, week, and year.
5. Re-regulate international commerce.
Herman Daly’s Top Ten 6-10
6. Limit the scope of the International Monetary Fund, World
Bank, and World Trade Organization.
7. Move to 100% reserve requirements instead of fractional
reserve banking.
8. Stop treating the scarce as if it were not scarce, and the
non-scarce as if it were scarce.
9. Stabilize population.
10. Reform national accounts to be able to measure when
growth is economic and when it is uneconomic.
Institutional Arrangements
The Market
• Employment
• Regulated banking systems
• Regulated international trade
• Stock markets and
investments
• Thriving local economies
The Commons Sector
• Property rights for
commons
• Trusts for managing the
commons
The Public Sector
• Governance for
sustainability
• Ecological taxation
• Competent regulatory
agencies
The Private Sector
• Ecologically sound
business operations
• Redesigned corporate
charters
• Limited demand creation

Changing Perceptions
Spreading the information:
We can’t jumpstart a
paradigm shift until people
know about the new
paradigm.
Inroads
The first text book for college
courses on ecological
economics came out in 2003.
CASSE’s position on
economic growth was
formulated in 2004.
The CASSE Position
• Carefully crafted position statement on economic growth.
• Based on years of study in the fields of ecology and
economics.
• Sanctioned by many leaders in sustainability science.
• Individual signatures for demonstrating widespread
understanding of the conflict between economic growth
and environmental protection.
• Organizational endorsements and adoption of similar
positions by professional societies to build a foundation of
advocacy.
http://www.steadystate.org/CASSEPositionOnEG.html
The CASSE Position
The Whereas Clauses
• Define economic growth, how it occurs, and how it is
measured.
• Point out that economic growth is a top policy goal, there
are limits to growth, and growth has negative effects.
The Therefore Clauses
• Recognize the conflict between growth and the
environment.
• Identify the steady state economy as a positive alternative
to growth.
• Recognize that other nations may still pursue growth to
meet needs.
