We can't tell China what to do if we don't do it ourselves. You don't inspire someone to take an action by refusing to take it yourself. We are in a race to be the dominant clean-energy provider to the world. Maybe this goes without saying: We've got to get China into an international protocol and the magic words are "common responsibility with differentiated action."
We [USA and China] have a common responsibility with different numerical targets, and that's the situation ultimately we are going to have with China. We emit six times more per person than they do. It's hard to tell them to cut theirs in half right now until we start moving. Being the ostrich with your head in the sand and tail feathers in the air like some would have us to do while China continues to pollute is simply not an option.
