>Russia, North Korea

North Korea is the most basket case country in the world Its emissions per capita are minimal.

Russia has seen its CO2 emissions collapse along with its post Soviet economy.

China has a whole host of issues that will be beyond the scope of this topic, but they will also be massively impacted by climate change. Way more than any western country not called Australia. (Though while Florida is not a country its another that is in for a very tough time)
