This changed on the last decade or so. It's close now.
Of course, China has 5 times more people than the US, so they get a little bit of leeway. But they are close, and their emissions are growing.
That said, yes, they are investing more than anybody else. And they are improving the technology we need more than anybody else. People talking about military intervention are full of shit, but we could use some diplomatic collaboration.
> and their emissions are growing.
I know nothing about it. I have read comments on this very comments section, with references, that say China's emissions are not growing. This is what makes this subject so hard for the average numbskull like me, so much misinformation.
It's still not that close. 15% for China vs 24% for just the US. Add in the EU-27 and it's 41%.
