CHINESE EMISSIONS OF HEAT-TRAPPING GASES
In 2018, China led the world in emissions of heat-trapping gases. Its emissions of roughly 13.5 Gt CO2e were approximately 25% of the global total.
This chapter starts by examining China’s emissions of CO2—the most important heat-trapping gas. Following sections discuss China’s emissions of other heat-trapping gases, uncertainties in emissions estimates and implications of China’s emissions for the global carbon budget.
