I'd move somewhere where the government and people actively care about climate change and don't just say "it's someone else's problem" or "nothing I can do as an individual will make a difference" or "you first!"
IMHO countries like Finland, Norway, Sweden. They are pretty hilly countries with a lot of natural resources and they are actively working for being as much environmentally friendly as it is possible for a country.
Unfortunately money rules this world so it's a good tactic to start paying taxes in place where government cares about environment. Hopefully at some point other countries will realize that investing in ecology is actually profitable.
