Research on the Calculation of Urban Transport Carbon Dioxide Emissions: A Case Study of Guangzhou City

Taking Guangzhou as an example, the calculation formula of low carbon transport has been improved by calibrating the energy consumption coefficient in this paper. On this basis, the annual transport carbon emissions of Guangzhou from 2011 to 2015 based on the statistical data has been calculated. At the same time, the transport carbon emissions in 2015 based on the data of Guangzhou Traffic Planning Model has been also calculated in this paper. By comparing these two kinds of calculation method, calculation method based on the data of Guangzhou Traffic Planning Model can measure the carbon emission of cross boundary transport and the carbon emission of small passenger cars more accurately. This method is also easier to measure the carbon reduction caused by the transfer of individual transportation to intensive transportation. Finally, it is concluded that the calculation method based on the Guangzhou Traffic Planning Model data source is more suitable for the study of carbon reduction in micro level transport.
