The chief reason why everyone is mad at Bush for not signing Kyoto is money.
The whole thing was designed to make everyone feel good and gain political popularity by appealing to their Green constituencies, while the U.S. picked up the tab. We were supposed to pay the enormous bill.
They were all planning to sell us "rights to pollute." That way, they would have gotten our billions, but they could still blame us for being the world's biggest polluters, never mind that we have done better in that regard than almost anyone else.
Oh hell. Clinton/Gore predated them in 1993 with Algore's "Carbon Tax" caper.
Even some Democratic congersmen figured out that was a non-starter and would get them unelected very quickly. So the "Carbon Tax" was killed early in the Clintooooooon/Algore imperial fiasco.
Incidentally, Clintoooooooooooon was bragging in Montreal that he wrote part of the Kyoto Accords. In point of fact, he didn't even sign them. Algore did.
