Resumen
Based on an empirical study in Shanghai, this paper firstly analyses distribution of commuting co2 emissions among the populations, and finds that almost 80% of emissions are from top 20% respondents. To find which factors make those people producing a disproportionately large share of emissions, this paper further analyses the link between individual socio-economic characteristics, transit accessibility, urban built environment and commuting emissions. The results show that among socio-economic characteristics, male gender, income and car ownership are strongly related with emissions. Rail accessibility doesn?t have a significant impact on emissions, while the influence of urban density is weak but significant.
