They gave numbers for the increase in coal, but not the increase in CO2. It's hard to know what the impact is
This made plenty of sense ten years ago, when for a smaller country you could compare their entire CO2 footprint to China's annual growth and ask why bother. But increasingly while China is still huge these comparisons look worse for even medium-sized countries unless they're actually on a sensible path. China is growing more slowly and importantly mostly by using more renewables and electrifying, so the comparison looks more uncomfortable.
