The others above USA are tiny countries. USA is at 14, Saudi Arabia at 20, EU at 5, China at 9. The reductions in absolute tonnage for USA are big because there's a lot of low hanging fruit left. And it's partly a petrostate.

China produces far more absolute emissions than USA.

I love how the intelligentsia claim without evidence that that per-capita is the important and moral metric when you talk about total emissions, then all of a sudden absolute emissions are the important thing when you point out that western countries are not at the top of the per capita lists either!
