The COP Summits are more than a talking shop. What gets agreed there goes to shape laws and policies around the world. The fossil fuel industry can see its own demise ahead; all it's doing now is negotiating the terms of its surrender. As recently as COP26 in Glasgow fossil fuels weren't even mentioned by name in the final summit agreement. So, it has scored a minor victory here. The language about its demise has softened, but it won't change the final outcome.
Politics matter, but maybe technological development matters more. What's really coming for fossil fuels is the spread of renewable energy tied to batteries. EV's are already 25% of new car sales in China, the world's largest car market - by 2030 how many new petrol cars will be sold there, or anywhere else?
