15. SD is related to interests
As you know, I oppose the Kyoto Protocol because it
exempts 80 percent of the world, including major
population centers such as China and India, from
compliance, and would cause serious harm to the U.S.
economy. The Senate's vote, 95-0, shows that there is
a clear consensus that the Kyoto Protocol is an unfair
and ineffective means of addressing global climate
change concerns.
16. The Global Challenge
Halving our usage of
environment/resources
Income in poor ‘South’ at least
50 % of ‘North’ in 2050
17. I=P*A*T
I Environmental Impact
P Population
A Affluence
Consumption of services and
products per capita
T Technology
Environmental burden per product
or service unit
18. 80-20 rule of thumb:
20 % of world population
consumes 80 % of natural
resources (fossil fuels, ores etc.)
Ergo: resource consumption Rich
world is 16 times more than in
Poor World
20. A Future in 50 years?
North 2 % growth
South 6-7 % growth
6-7 % growth for 50 years means: factor 18-30
2 % growth for 50 years means: factor 2.7
Result:
- Equity difference reduced from factor 16 to factor 1.5-2.4
- Growth resource consumption: Factor 5.8-8.2
