Al Gore and his suporters in Europe want to take the CO2 induced global warming scare to gain support for a world government. Here is an example that I got from "Junkscience:"

Carbon trading must be globally regulated

Simon Linnett, Executive Vice-Chairman of Rothschild, has called for a new international body, the World Environment Agency, to regulate carbon trading.

In a recently published paper, Trading Emissions, for the Social Market Foundation, Mr Linnett argues that the International problem of climate change demands an international solution.

Unless governments cede some of their sovereignty to a new world body, he says, a global carbon trading scheme cannot be enforced and regulated. (London Telegraph)

Carbon trading is a truly stupid scheme that is being tried unsucessfully in the EU. If you truly believe that we need to limit CO2 generation, then you have to be disappointed by the reductions resulting from carbon tradind. Carbon trading will make Al Gore and his friends billionaires.
