It's more important to understand why they're emitting so much of that CO2 - because a lot of people in China need to eat and have a roof over their heads.

Any analysis that fails to take per-capita into account is not made in good faith.

China has a large population but so does India. Don't forget that China is the world's factory and that's where a very large chunk of CO2 emissions come from.

My point is that if you pay a factory in China to make something for you, then the CO2 produced in that process would be more appropriately added to your total, rather than theirs, because it was you were the direct and only reason it was produced.
