Well, that's not quite what Clinton meant. Here's the full context:
And maybe America, and Europe, and Japan, and Canada — the rich counties — would say, 'OK, we just have to slow down our economy and cut back our greenhouse gas emissions 'cause we have to save the planet for our grandchildren.' We could do that. But if we did that, you know as well as I do, China and India and Indonesia and Vietnam and Mexico and Brazil and the Ukraine, and all the other countries will never agree to stay poor to save the planet for our grandchildren.So the whole point is that it's something we should not do!
