Humanity is way too slow in getting global greenhouse gas emissions down. First, wealthier countries need to be going fast like us, and then we also need to be using trade measures to make sure that other countries around the world are acting and following that.
The policies we need, I really argue, should be at a federal level, and they should be focused on emissions. That was my first point, so I will stick with that point. We're so much closer to that than we were 10 to 20 years ago, so I'm quite encouraged.
I'll stop there.
