First, make it a goal to get to zero—by 2050 for rich countries, and as soon after 2050 as possible for middle-income countries. Second, develop specific plans for meeting those goals. To get to zero by 2050, we’ll need to have the policy and market structures in place by 2030. And third, any country that’s in a position to fund research needs to make sure it’s on track to make clean energy so cheap—to reduce the Green Premiums so much—that middle-income countries will be able to get to zero.
