Well, you can look at where most of Canada's CO2 is produced, and it is in provinces that extract oil. So I would assume our emissions are higher becuase they count against us, even though we export a lot of it. I'd suspect if you took the extraction part out, and applied it to where oil is consumed, Canada(and Alberta) wouldn't look as bad. The externalities, like some in China for their production of goods for us, get mis-attributed.
