"Before anyway throws the "they export their pollution" argument at me, you need to look at the stats on global GHG per capita." I think it's more useful to look at carbon emissions per unit GDP, and the change therein. Stuff has to be produced somewhere, and it doesn't matter to the Earth where. What we want is for it to be produced as carbon-efficiently as possible. By this standard the U.S. still has a way to go to catch up with Europe, but it is catching up, rapidly (and our Canadian friends are weirdly awful, I guess because of tar sands and growing food in greenhouses).
