This doesn't do anything about developing countries as this technology is expensive, harder to implement and maintain, and needs significant infrastructure to support. Further, anyone who mentions China in a positive light on this subject I find difficult to take seriously. They are leading in nothing in this area. That narrative is all lies mostly based on bashing the U.S.

Conversely, the U.S. is actually a leading nation in innovations. We've done the most to advance battery technology and implement all kinds of alternative energy sources and are continually developing them. The difference between the U.S. and other nations is we let the private market work on the problem vs the government, which usually works out better.
That said, it's still not going to be available to developing countries and as more and more countries advance, CO2 output are going to increase, a lot. Not to mention that, by all accounts, he policies that we'd have to implement to effect the change that is needed are so extreme that they will literally never happen. So we are in for w/e is coming our way, good, bad, or indifferent.
