1960-2009年中国民航飞机的CO2逐年排放变化

摘要

基于中国民航部门逐年统计数据,计算了1960- 2009年中国民航飞机的CO2逐年排放量,分析了中国民肮飞机CO2排放强度及其变化特点.结果表明:中国民航飞机CO2总排放量由1960年的12.0万t增至2009年的4144万t;CO2排放强度呈明显的降低趋势,由1960年的2.9 kg/换算吨公里降至2009年的0.96 kg/换算吨公里,年均降低0.04 kg/换算吨公里.中国民肮飞机的CO2排放量占整个交通运输仓储和邮政行业CO2排放量的比例较低,仅占6.6%,占全国化石燃料燃烧CO2排放量的比例也很小,平均只有0.25%.%Based on the annual production data collected by Chinese Civil Aviation Statistic Center, the yearly CO2 emission of aircrafts during 1960-2009 was calculated, and the emission intensity and its dynamic characteristics were analyzed. The results show that the total CO2 emission of aircrafts in China increased from 120 kt in 1960 to 41.44 Mt in 2009. The emission intensity of CO2 decreased from 2.9 kg/(converted t · Km) in 1960 to 0.96 kg/(converted t · km) in 2009 at an average rate of 0.04 kg/(converted t · km) per year. The average proportion of the CO2 emission of aircrafts to the total CO2 emission from the sector of transportation, storage and post was 6.6% in the period of 1980-2005, and to the total emission from fossil fuel combustion was 0.25% in the period of 1971-2008.
