For more details on this excellent idea by Nobel Prize winning William Nordhaus: https://issues.org/climate-clubs-to-overcome-free-riding/

This idea is one that has me slightly less pessimistic about the chances of the world actually doing something about climate change. We don't have to have 195 countries agreeing to a plan and have huge advantages accrue to cheaters who don't follow the plan. We can start with a small but significant number and it's the cheaters that lose out.
