It doesn't, it also doesn't account for the fact that China has a larger population. The US only has about ~23% of China's population to sustain. GDP/CO2 is a silly metric to compare (No Patrick, selling financial products to increase GDP/CO2 isn't green).

In reality China is just "greener" (in CO2 emission) than the USA if you measure more reasonable metrics like CO2 emission per capita.
