India also has 32X smaller GDP per capita. Meaning they produce 16X more emissions per unit of productivity than America.

I don’t think this makes sense because American productivity depends so much on pollution outsourced to countries like India. For example, if US cars are assembled “greenly” from components that are manufactured dirtily, then it hardly seems meaningful to brag that America’s productivity is “greener”. And do bear in mind that I’m not one of the folks who are determined to make the US out to be the bad guy in every thread.
