The transport sector is one of the most important and potential sectors to achieve low-carbon development in China. As economic growth is desirable, but high-level traffic CO 2 emissions are not. This paper estimated the on-road traffic CO 2 emissions and investigated the decoupling states of traffic CO 2 emissions from economic growth for six cities in Hebei province from 1995 to 2015. In 2015, the on-road traffic CO 2 emissions were ranked, as follows: Tangshan (4.75 Mt) > Handan (3.38 Mt) > Baoding (1.38 Mt) > Zhangjiakou (1.05 Mt) > Langfang (1.01 Mt) > Chengde (0.46 Mt). Two turning points of traffic CO 2 emissions during the study period were found. From 2008 to 2013, the traffic CO 2 emissions increased more rapidly than before. After 2013, the traffic CO 2 emissions of three cities (Baoding, Handan and Chengde) began to decrease, and the traffic CO 2 emissions' growth rates of the other three cities (Zhangjiakou, Langfang and Tangshan) became lower than before. The decoupling states during 1996-2015 can be divided into four phases: decoupling-coupling concurrence stage (1996)(1997)(1998)(1999)(2000), decoupling dominant stage (2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008), coupling dominant stage (2009)(2010)(2011)(2012)(2013), and improvement stage (2014)(2015). Chengde and Baoding were identified due to their good local practice on decoupling CO 2 emissions in transport sector from economic growth. These results will enrich the greenhouse gas inventory of China at city level and provide scientific support to achieve the mitigation of CO 2 emissions in the transport sector.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
