Isn't mpg also a factor in terms of emissions? A lot of these tanks are gonna be more thirsty. SUVs also account for much of the increase in co2 emissions although when I read that stat it didn't breakdown where in the world those SUVs are being bought (I imagine some are being bought in developing economies that are adopting an American model).
