Huh, somehow in my head I remember it as ~750 million. I wonder where I got that number from. I think my point still stands though, they have 115 million more people and yet the US has almost twice the proportion of global emissions.
Well I'm not only talking about the Chinese government but yes even in their case they do, in fact especially in their case because its how they derive their political legitimacy. The social contract there is basically that the CCP monopolizes political power and in exchange they deliver pro-growth technocratic governance.
