According to that article: "China’s coal consumption growth was responsible for more than half of global CO2 emission growth in the past 10 years."

China gets over 70% of its electricity from coal. Yes, they are building more solar but it'll take over a decade for there to be significant change.

Anyway, the real problem is that even if everyone somehow meets the Paris limits, it's not enough.

And they're building nuclear plants too.

They currently get 2-3% of their electricity from nuclear:

A 5x increase in 15-20 years gets you to 10-15%. While that's good, I don't think it's enough given the current rate of CO2 production. It's hard to complain because they're doing a lot more than everyone else. Unfortunately, we need to find a way to do more.
