alt Hacker News>it was agreed that they would all aim to reduce emissions
No, it was agreed during Kyoto that developed nations would reduce emissions, and developing nations (aka PRC, India) would not. Developing nations could keeping scaling fossil to industrialize until Paris where all countries had to submit climate plan (again not explicitly to reduce), and PRC's was to peak emissions by 2030s, which they're on trend to do early. PRC did what was legally permitted / agreed upon, and if developed nations want to cope / be butthurt and label following the agreement as dirty and not cooperate in the future global projects because they're not financial beneficiaries then that's on them. Also "some" solar and wind is ~ROW combined, which surely is very unimpressive.
> sell the solution
Selling solution to problems is solving problem, selling solutions to problems cheaply is solving said problem faster. As if developed economies did not decarbonize by selling clean tech solutions... which btw PRC bought. PRC simply doing globe a favor by selling real climate solutions at cost and scale that makes global difference, instead of scaling retarded paper solutions like carbon credits from countries that primarily scales spreadsheets.

Lots of this is right, but
> and PRC's was to peak emissions by 2030s
This appears to be wrong. Peak is supposed to be before 2030. They will not hit it.
China is not a developing nation. At that time they were more than wealthy enough to implement the same regulation as other nations and their industry was already developed.
They are not on trend to peak emissions pre 2030. Here is what happens Reliable china emission data takes a long time to verify and collect. So during the times where good data is not available china makes a ton of claims that will not line up with the next emissions study that comes out.
Ok then why does every country scale up their manufactering to make clean tech solutions. Im sure US, EU, India and Africa could use a few more steel mills and some coal plants to power it, we can handwave the emissions if they end up producing clean tech.
