Greenhouse gas emissions by China are the largest of any country in the world both in production and consumption terms, and stem mainly from coal electricity generation and mining. When measuring production-based emissions, China emitted over 12 gigatonnes (Gt) CO2eq of greenhouse gases in 2014; almost 30% of the world total. This corresponds to over 7 tonnes CO2eq emitted per person each year, slightly over the world average and the EU average but less than half the second largest emitter of greenhouse gases, the United States, with its 16 tonnes. In consumption terms, China emits slightly less, with over 6 tonnes in 2016, slightly above the world average, but less than the EU average (close to 8 tonnes) and less than the United States by more than a half, with close to 18 tonnes per pers
