There is a lot of headroom until China even reaches US levels of pollution per capita though. The USA is emitting ~2.5x as much GHG per capita than China.
Also China is the workbench of the world, other nations just shift their GHG load there, first and foremost the US.
- Decreasing per capita emissions in the US starting in 1973 (-27%)
- A decrease in the countries emission starting in 2007 (-13%)
Meanwhile for the same period China has had
- a 7x increase per capita since 1973 (+532%)
- 48% increase for its global emissions since 2007
So it is possible to drastically reduce our carbon footprint thanks to innovation and smarter power generation.
