Carbon emission and its decoupling research of transportation in Jiangsu Province

Transportation in Jiangsu province has been developed rapidly. However, the development was accompanied with a large amount of energy consumption and carbon emissions. Combined with the coefficient in 2006 Intergovernmental Panel on Climate Change (IPCC) guidelines for national greenhouse gas inventories and China's calorific value, this article calculated the carbon emission coefficient of usual energy covered by Jiangsu Statistical Yearbook (JSY) in detail. Based on this, carbon emission of transportation in Jiangsu Province from 1995 to 2012 was easily estimated. And from the result which appears clearly that the construction of energy consumption was changed in 2011. According to China Electricity Power Yearbook (CEPY) and China Energy Statistical Yearbook (CESY), carbon emission caused by electricity power indirectly could be estimated. With the help of Tapio model, this paper conducted a research on decoupling relationship between economic growth and carbon emission of transportation in Jiangsu Province with consideration of electricity. The results show that the amount of carbon emission by electric power is significant, which makes no difference on the overall decoupling states with an obvious periodical characteristic of Weak Decoupling (Expansive Coupling)-Expansive Negative Decoupling-Weak Decoupling. Transportation has made great achievements on reducing pollution and carbon emission in Jiangsu Province since the Eleventh Five-Year Plan, and would be better on low carbon development in potential. However, there is still a large step to realize low-carbon transportation in reality. (C) 2016 Elsevier Ltd. All rights reserved.
