2007: in US, 1.4% increase over 2006 (mainly from CO2)
The ratio of carbon emissions produced to GDP.
“Bush Plan”: Called for 18% reduction in CI by 2012.
However, CI dropped by 17.4% between 1990 and 2000.
China’s CI dropped 47% during ’90-’00 while emissions increased 39%
Environmental change has resulted from:
4) economic integration: promoted through globalization (Fordism) led to mass consumerism and the “growth imperative”
UNEP (p. 132):“Human activities are progressively reducing the planet’s life-supporting capacity at a time when rising human numbers and consumption are making increasingly heavy demands on it. The combined destructive impacts of a poor majority struggling to stay alive and an affluent minority consuming most of the world’s resources and undermining the very means by which all people can survive and flourish.”
2 Driving Forces of Environmental Change:
1.Overuse or misuse of resources
2. Increases in pollutive outputs (mercury, GHGs, CFCs, Toxic Chems, etc)
This has led to affluence (in the North) without responsibility for the consequences:
1. underwritten by the degradation of people (South and lower classes in North) and land, biosphere, and environment.
2. While in the South, factors such as increased population and low technology also caused environmental stress.
So, many scholars see that environment problems are tethered to larger social, moral, ethical issues in which these environmental problems are embedded.
- Stockholm Convention (’00) on Persistent Organic Pollutants (POPs)
Environmental Impact = Population * Affluence * Technology
I = P A T
Population: Size of human pop
Affluence: level of consumption
Technology: processes designed to transform raw materials
* Ex/ (P doubles * A (per cap income) triples = 6 fold increase in CO2 emissions. If only 4 fold increase, then technology mitigating factor
1. Population is part of problem
2. Enviroprobs are more than pollution
3. Enviroprobs driven by multiple factors that compound
