sure a recent US report claimed that CO2 emmissions went down over
over 2001-2003 but that just happened to coincide with the downturn of the US
economy.

the way co2 emissions are calculated also dont help, since 1990 Canadian oil and gas exports to the US increased 20%. (however that increase is counted on the Canadian side, not on the US where it actually gets used).

it is true that some US industry and many US cities have started to deal with greenhouse gas emissions - all done in spite of Bush's policies, because they know the writings on the wall, the change is inevitable.

Kyoto was only a step, but it has spurred investment in wind generation as well as other
greener energy options.

also the US is 5% of the worlds population but causes 25% of the worlds pollution.
