"But the economy" is an out-of-date framing. The cost of renewables has been plummeting for well over a decade. New renewables are now cheaper than new fossil fuel plants in most of the world, and in many regions they're already competitive with or cheaper than simply running existing fossil fuel infrastructure. As modern wars in Ukraine and now Iran are increasingly demonstrating, they are not only cost effective but rapidly a matter of energy sovereignty and national security.

That's not to say we won't need treaties and supranational entities for some aspects of decarbonization. Methane emissions outside of agriculture are notably a problem of enforcement.

We're badly in need of a collective update to our priors regarding renewables. In the US, a hostile policy toward renewables is not only shooting ourselves in the foot environmentally, we are now actively impoverishing ourselves due to entrenched economic interests across the fossil fuel industry and the cultural inertia they actively worked to develop.
