In 2018, China’s CO2 emissions were roughly 11 Gt—approximately 28% of the global total. Roughly 9.5 Gt were from combustion of fossil fuels (coal, oil and gas). Most of the remainder were industrial process emissions. China’s CO2 emissions exceeded those from the United States and European Union combined.
