 So we're trying to solve a problem by excluding 60% of it and thinking the other 40% could amount for the whole. Obviously, mathematically, that's impossible. So I think as we focus, and I know a lot of people are concerned about climate change and some of these climate concerns, but in the world of multilateralism, when emerging economies like China and India don't have to participate as part of the solution, it's really a massive economic disadvantage to developed economies like Europe and the United States.
