Because people in India and China want air conditioned malls, meat for every meal, and private cars. The governments in these regions are absolutely dependent on keeping those countries on a path to western prosperity for their legitimacy. Any climate change plan that contradicts that isn’t a serious plan and will fuck us all.

Then let the west (which has by far the largest carbon emissions per capita) lead the way! Show the world that prosperity isn't necessarily 2 cars and a heart attack at 67.

And to people saying it is not possible, I call bullshit. There are large carbon footprint variations within the West. Of course countries have different circumstances, but it's also very clearly a question of political will.
