The impacts of household features on commuting carbon emissions: a case study of Xi'an, China

摘要

This study contributes to the analysis of the household characteristics and household neighborhood ones affecting the transportation carbon dioxide emissions produced by commuters. This analysis integrated the household commuting measures of the travel mode, frequency, distance and household demographics using datasets from a metropolitan scale survey in the city of Xi'an, China. The results of the tests that used the field data from Xi'an, revealed that a significant positive relationship between commuting emissions and household size, income, and education level. Moreover, there is a significant relationship between the average age in the household and the commuting emissions. The methodology developed in this study measured the regional emissions by incorporating the impacts of the household characteristics and household neighborhood ones on the commuting emissions. A further exploration of the data showed that regional commuting carbon emissions are more likely to have a positive relationship with the mixed urban land use.
