Per capita data for ghg emissions is an American invention to make them look better than they are....guess that China and India are entitled to increase their per capita emissions to the US level as you see it. The Americans intentionally sent all their high GHG emissions industry along with the jobs to India and China ten years ago.  By the way, we are not number 1 per capita ....you might want also reflect on the fact that global forest lands and global oceanic consumption of ghg is 65% of our global emissions...you are focusing solely on the emissions side. Canada is number 2 in forest lands and number 1 in oceanic coastline area.
