中文摘要：

对2006—2012年天津市交通碳排放量以及不同出行方式的碳排放量所占比例进行了核算,分析了该市的交通碳排放结构变化特征,并将其与北京市和上海市的交通碳排放结构进行比较。结果表明,该市近年来交通碳排放量迅猛增长的主要原因是私家车出行比例的快速增加以及公共交通发展的欠缺。在此基础上,对天津市低碳交通的发展提出了建议。

英文摘要：

The traffic carbon emissions and carbon emissions of different traffic modes of Tianjin in 2006-2012 were calculated. Then the change of traffic carbon emission structure was analyzed,and also compared it with Beijing and Shanghai. The results showed that, the main reason for the rapid growth of traffic carbon emissions in Tianjin were the rapid increase in the proportion of private car travel,as well as the lack of public transport development. Fi- nally, suggestions of the development of low carbon transportation were put forward.
