Let's assume rich countries of the world (e.g. G7) set up a climate change fund in a smart contract. They could just lockup some funds there to be claimable after x months/years for any country (except the G7) proportionally to how far they managed to reduce their CO2 emissions. This assumes that we can trustlessly get the CO2 emissions for all countries (Let's just assume satellites can provide that data in a trustless way to the blockchain via some clever oracle mechanism).
Instead of having a handwritten weak contract like the Paris climate act, you'd have actual enforceable code that can not be gamed. I'm obviously oversimplifying things here but this is just to give an idea how blockchain tech can improve coordination games in the future.
