Carbon Emission Calculation and Scenario Analysis of Urban Passenger Transport in Nanjing

In order to slow down the global warming trend, accelerate the realization of the goal of "carbon peak and carbon neutrality". Taking Nanjing urban passenger transport as the research object, this paper analyzes the development status of urban passenger transport. On this basis, taking the CO2 generated by energy consumption as the measurement caliber, the "top-down" method is used to calculate the CO2 emission of Nanjing from 2014 to 2019. At the same time, taking the carbon peak in 2030 as the constraint boundary, assuming ideal, enhanced and radical scenarios, the energy structure objectives and power demand are analyzed. The research results show that the carbon emission in 2019 is 13260kt, 1.6 times that in 2014. In addition, Nanjing’s urban passenger transportation carbon emissions may reach a peak in 2030, and the proportion of electric cars should be increased to 26%-30%.
