However, the US's per capita CO2 level keeps decreasing, while China's is increasing at a rapid rate. It's already 60% of the US's level and at this rate will eclipse it in the next few years. So any solution to climate change that does not take China's emissions into account is doomed to fail just as much as one that doesn't take the US's emissions into account.
