China is 1.4 B people; why wouldn't it have higher co2 emissions than EU and USA?

Anyways. We can chat about particular data points. But if you look at the broad picture over decades; you really have to be willfully blind to deny massive improvements that have happened.

The claim though was that it had improved on these and other points. And at least on these there seem to be a big and widely published degradation.

Can always talk about data on the other points as well to see what they say.
