ABSTRACT
Public transport buses traversing in urban areas emit extensive carbon dioxide (CO2). It is critical to understand and estimate the characteristics of carbon emissions for transit buses to achieve a low-carbon transportation system. This paper compares the CO2 emissions between electric buses and conventional buses. We use the mobile sensor data of electric buses collected from Shenzhen to calculate CO2 emissions. To evaluate the CO2 emissions impacts of electric buses, we design four scenarios of different replacement rates of a conventional buses fleet by electric buses as a case study. The results demonstrate that the CO2 emissions of electric buses fleet can be reduced 34896.512 tons in comparison with conventional fuel buses by 2023. And the reduction rate of CO2 emissions will be 20.601%. Moreover, the reduction rate of CO2 emissions will be 0 if the CO2 emissions intensity is 742 gCO2 /kwh.
