CHINESE EMISSIONS OF HEAT-TRAPPING GASES
In 2017, China led the world in emissions of heat-trapping gases. Its emissions of roughly 11.7
Gt CO2e were almost one-fourth of the world total.1
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.
