The Role of Germany in Global Climate Policy

With the United States and China as these two big players I wonder how this also applies on climate policy. Germany obviously focuses a lot on climate policy it's the subject of a lot of domestic politics right now but yeah how much does Germany really matter for global climate policy? "I don't think we should put the China and the US in the same pot," he says. 'China is responsible by itself for almost 28% of global CO2 emissions'
