Shouldn't the USA pay for China and other nations to be green?

Once the United States enacts laws to increase their control on climate change emissions, we will enjoy a better earth. Don't you think we should pay for China and other industrial nations (like India) to be clean as well? The only reason they don't want to be green is because it would cost them trillions and cause the prices of their products to skyrocket. Don't you think the United States should pay so poorer countries don't have to?
