Kyoto was about getting the western world, the biggest producer of greenhouse gases, to start trying to reduce those emissions. Every other major power was either already on-board or waiting for US assent before they agreed. No meaningful action could be taken without the US. The US deliberately and wantonly trashed the treaty out of pure self interest. Let's not re-write history, eh? Everyone in the west, especially in the environmental movement knows only too well how important kyoto was and how devastating it was that the US decided it was not going to take its responsibility for its own actions seriously. Your reason for why the treaty wasn't signed is pure fantasy/propaganda and if you believe it then you are a fool. The treary was not signed for ONE reason : It would have meant the US would have had to raise prices of gasoline to its own internal market, which would have been politically unacceptable to the US public. Please do not compound the irresponsibility with lies.
