Abstract:According to the data of energy consumption and transport turnover from 2004 to 2008 in China, carbon footprint of transportation industry was estimated through carbon footprint model. The results show that total carbon footprint from transportation energy consumption in China is growing continuously, and increases from 3.702 534×108 t in 2004 to 4.884 943×108 t in 2008 with an average annual increase of 7.17%.The direct carbon footprint from terminal fossil energy use in 5 years accounts for 89.06%. Carbon footprint from diesel consumption accounts for the largest proportion in total carbon footprint with 46.65%. The second proportion of carbon footprint is from gasoline consumption with 17.85%, and shows a similar rising trend from diesel consumption to that year after year. Per unit conversion turnover carbon footprint shows an obvious declining trend, and drops from 485.72 kg·(104 t·km)-1 in 2004 to 408.45 kg·(104 t·km)-1 in 2008 with average annual decline of 4.24%.
