I can't say I'd blame them. As long as there are other countries gaining an economic advantage at the cost of environmental damage then I don't see that another country should pick up their crap and decrease their export because it's so cheap to produce in such "dirty" countries.
As long as there is such an active oil lobby and alternative energy sources like nuclear fusion is being treated like something from Star-Trek I don't see any short term improvement by forcing countries to reduce their carbon footprint.
BTW: Has Canada been given the favor they their trees are eating up a lot of the world's carbon dioxide and producing oxygen? Prolly the next thing scientists are coming up with is that oxygen is making global warming even worse.
