Estimation of the Aircraft CO2 Emissions of China＇s Civil Aviation during 1960-2009

摘要

Based on data collected by Chinese Civil Aviation Statistic Center, the annual CO 2 emissions of aircrafts during 1960-2009 were calculated, and the emission intensity and its dynamic characteristics were analyzed. The results show that the total CO 2 emissions of aircrafts in China increased from 120 × 10 3 t in 1960 to 41.44 × 10 6 t in 2009. The CO 2 emission intensity decreased from 2.9 kg (converted t km) 1 in 1960 to 0.96 kg (converted t km) 1 in 2009 at an average rate of 0.04 kg (converted t km) 1 per year. The average share of CO 2 emissions of aircrafts on the total CO 2 emissions from the sector of transportation, storage and post was 6.6% during 1980-2005, and 0.25% on the total emissions from fossil fuel combustion during 1971-2008.
