everyone else in the comments

You're trying to misrepresent reality again - go look at the comments (of which 1/2 are now just us two bickering); and fully 1/2 (7/14 (excluding us two), of the (as of posting) 28 total comments (including us two) (edit: this is confusingly worded, I apologize)) of the other comments in this thread are critical of the claims, most of those criticizing how sorry this promise is from China. You can't just assert easily-verified falsehoods as truth and then claim some kind of victory from that (despite that practically being codified US policy at this point...).

I chose to focus on criticism because they are leading the pack, and their efforts are sad, much like a great many other people in this thread are doing. I suppose a case could be made for that to include their politics, since politics shapes policy, but that'd be a kinda pointless semantic argument to make. My criticism of China has nothing to do with my distatste for the CCP directly and everything to do with them being the #1 global emitter of greenhouse gasses, and then even in lip-service planning to do the barest minimum. I'm not criticizing the US right now because the US is not the leader of the pack, or even relevant in this discussion (beyond being the #2 emitter).

To put in context something, this year if China's planed 10% reduction had gone through instantly at the start of the year, they would still have produced more than double the greenhouse gas emissions of the US. THEY HAVE TO DO BETTER. We all do, yes, but THEY ESPECIALLY have to do better. It ain't fucking racism to criticize the #1 culprit for choosing a target that barely does anything.
