Title: Module 3 The Economic Context
1Module 3The Economic Context
- BCN 1582
- International Sustainable Development
2Terminology-Module 2
- Terminology
- Substitutability
- Ethics
- Environmental Ethics
- Biocentrism
- Ecocentrism
- Anthropcentrism
- Environmental Justice
- PV, BIPV, Fuel Cell, Wind Energy
3Concepts-Module 2
- What is environmental ethics?
- Different ethical points of view
- Impacts of environmental degradation on the
poor-environmental justice - Redesign of the worlds energy systems
4Main Points
- Everything is connected
- The result is there are feedback loops between
all - GDP and GNP do not really represent welfare
just economic throughput - Maldistribution of wealth is prevalent but not
sustainable - The economy responds to signals it is sent
- Cheap waste disposal
- Low costs for emissions (air, water, land)
- Low cost for environmental impacts
- Cheap and subsidized resources
- Tax benefits for resource depletion
- How do you change the signals to the economy?

8The Production System?
Life-Cycle Cost and Economic Analysis, W.Fabrycky
and B. Blanchard, Prentice-Hall, 1991
9Sustainable Economic System
- Accounts for true costs of waste and disposal
- Cradle-to
- Grave responsibility for products
- Penalizes waste, rewards efficiency

11Economics Terminology
- Economics the study of the allocation of scarce
means among competing ends. (Daly) - Capital wealth of property that is used or
invested to produce more wealth the money with
which an enterprise is started. Set of all
physical things capable of satisfying human wants
and subject to ownership. Fisher (1906) - natural, human, manmade, critical natural
- Wealth Riches, possession of these.
- Riches a great quantity of money or property or
valuable possessions. - Money portable pieces that can be used as a
medium of exchange. Banknotes or coins.
12More...
- Technology mechanical arts and applied
sciences. - Growth increasing in size by accretion or
assimilation of material. A quantitative incease
in physical dimensions or size. - Economic Growth rising aggregate consumption
(C) or output (Q). - Development bring to a fuller, greater, or
better state.
13Physical Limits to Economy
- Malthus absolute limits or scarcity
- Ricardo relative limits
- Marx limits due to social and political unrest

15Ecological Economics
- A new transdisciplinary field addressing the
relationship between ecosystems and economic
systems in the broadest sense. - Uses the tools of conventional economics and
ecology as appropriate. - Need to establish institutions that take the long
term view, a la biology - Economics as an ecological system

16Hicksian Income
...income that can be consumed without reducing
future consumption possiblities
17The Ecological Economists
- Kenneth Boulding (1910-1992) The Economics of
the Coming Spaceship Earth (1966) - Nicholas Georgescu-Roegen (1906-1994) The
Entropy Law and Economic Progress- the economy is
not a reversible mechanical systems but subject
to the 2nd Law - Herman Daly student of N. G-R., steady state
economy

Environmentalists, St Lucie Press, 1995, 129-132.
18Economy like ecosystem?
- Eugene Odum
- young ecosystems production, growth, quantity
- mature ecosystems protection, stability, quality

20Changing the Signals to the Economy
- Currently taxes are applied to positive aspects
of behavior wages, productivity, profit - It would be better to tax aspects that are
negative waste, inefficiency, pollution - Possible mechanisms
- Pollution taxes
- Tradable pollution permits
- Deposit fees
21Internalization
- Benefits of Internalization Processes
- Transparency
- Across All Sectors
- Flexibility
- Stimulates Innovation
- Polluter Pays
- Caveat must be transnational
- Cooperation between sectors
- Another example of interconnectedness
22Tax revenue, select countries, 1994
23Tax shifts from work investment to
environmental damage
24Pollution Taxes
- Air Pollution 209/t
- Water 10,788/t
- Solid Waste 104/t
- Hazwaste 24/lb
- Leaking UST 3959/t
- Pesticides 1.35 lb active ingredient
- Toxic chemicals 0.165/lb

27Bionomics
- The economy behaves like a biological system
- Behavior of biological systems applied to
economics - Excellent forecasting tool (e.g. ATT demand for
telephone service)
28Summary and Conclusions
- The current economic system is not sustainable
- Depends on the scale of material/energy
throughput - Subsidizes resource extraction and pollution
- Taxes productive activities
- Does not measure welfare
- A system based on Ecological Economics would
- Shift taxes to waste, inefficiency, and
pollution, away from wages, profits,
productivity, and investment - Focus on dematerialization, deenergization,
decarbonization, and detoxification - Measure welfare instead of absolute monetary
transactions - Support an EcoIndustrial revolution
29Module 3- Sustainable Materials EconomySome
Background
- Average American Uses 37 tons of materials per
year - Total U.S. 10 billion tons
- 1900 20 elements Today 92 elements used
- 100,000 synthetic chemicals produced
- Copper extracted at 3 concentration in 1900,
today at 0.5.22-fold growth - Subsidies
- 1872 US law gives miners title to federal mining
land for 5.00/acre - U.S. government spends more on logging roads than
it earns from timber sales
30Problems with Materials Flows
- Sustainable materials flows humans move as much
material as natural systems and forces - Current We are moving 2x as much materials as
natural systems and forces (storms, hurricanes,
tornadoes, tidal waves) - Forestry threatens 70 of the worlds large
intact virgin forests
31- Mining Canada produces 58x as much mining waste
as municipal solid waste (MSW) toxic chemicals
(cyanide, mercury, sulfuric acid) storage
reservoirs - Ecological Rucksack materials moved to produce a
unit of a given end product (e.g. it takes 3 tons
of earth movement to produce 1 gram of gold),
producing a rucksack of 300,0001
