CO2 emission of Chinese airlines

Civil aviation is a high energy consuming traffic department. Based on the method of the Intergovernmental Panel on Climate Change (IPCC), the CO2 emission amount and emission intensity of Chinese air transportation and typical airlines from 2005 to 2014 were calculated in this paper. Through the comparative analysis, it can be found that, with the CO2 emissions of Chinese air transportation and typical airlines increasing significantly, the emission intensity of CO2 was basically tended to decrease year by year, and, the CO2 emission intensity of Spring Airlines which is one of the private airlines is much lower than Eastern Airlines which is one of the central enterprises, and is also lower than Hainan Airlines and other local airlines. Finally, it's suggested to put forward some measures to reduce fuel consumption per ton-kilometer and optimize the emission intensity of CO2 such as by improving the guest rate and load factor.
