Large-scale rail transits have been constructed in China. Many cities have also extended their rail transit networks extensively to suburban areas where car dependency is relatively high. To understand the impact of rail transit proximity on commuting greenhouse gas emissions in suburban areas, surveys of two sites in Shanghai were conducted in 2010 and 2011 respectively. CO2 emissions were calculated based on the mode used in each segment of commuting and distance travelled. The relationship between commuting CO2 emissions and demographic characteristics, transit proximity, built environment as well as car ownership was also established. The availability of rail transit has an impact on people’s mode choice in commuting. But there is also the case that CO2 emissions from people living in areas close to rail transit surpass the emissions from people residing far away. More specific policies are worth of exploring to reduce those people’s commuting emissions.
