Yeah, it's cherry picked data. Although perhaps the US as whole produces more ghg's, per capita it comes in about fifth behind Russia, Canada, Australia and Saudi Arabia respectively (and first is "Middle East A" which is a cohort that includes Saudi Arabia for some reason).

^Where the claim comes from. AFAICT the claim focuses on consumption of products and includes the CO^2^ of creating that product (shipping as well?) to the states where it is then used. So, as China is one of the main manufacturers some/most of the carbon emissions created by those products is instead included in the United States emissions. In short, the US has the largest consumer base, so it has a larger carbon footprint.
The question I have then is; is this not included in the per capita data? I unno, and I don't really care enough to find out.
