I understood your argument, and I did already address the point you want to continue with here.

> ultimate use (who buys the end product of China's emissions), and historical contributions. However, to ignore China's absolute , ongoing contribution as the world's largest emitter (by far: https://ourworldindata.org/grapher/annual-co2-emissions-per-...) is clearly an error.

"Ultimate use" discusses consumption by the West. This fact does not exonerate China, as China directly causes the emissions in order to satisfy its economic ambitions, and profits from its _factual_ role as the leading emitter of greenhouse gases. If China did not offer these exports, perhaps someone else would. But right now, it's China.

I also threw in "historical contributions" to throw you a bone. Nonetheless, right now, its China and China's emissions are, even still, increasing.

If you want to pass the buck to the West that's fine, but the reality is that China is producing more emissions than anybody else is, and it does it for the benefit of China at the expense of the planet.
