Analysis of the contribution of rail transit to carbon emission reduction of urban transportation:A case study of Shanghai
摘要
Abstract
As an important part of urban public transportation,rail transit has made outstanding contributions to the green development of low-carbon transportation and the reduction of greenhouse gas emissions from mobile sources.Quantitative analysis of the carbon emission reduction contribution of rail transit to urban transportation will provide a theoretical basis for the construction of low-carbon cities and green management.Based on this,this study took Shanghai urban rail transit as an example,taking the carbon emissions generated by the energy consumption of lines and stations during the operation period of rail transit as the accounting boundary,to establish a"bottom-up"carbon emission reduction accounting method.The annual carbon emission reduction of Shanghai rail transit in 2023 was estimated to be 4 355 304.39 t CO2.Through analyzing the impacts of passenger flow and energy consumption on the carbon emission reduction of rail transit during the operation period,and comparing the carbon emission reduction potentials of typical regions and routes,the results showed that the rail transit still had a huge space for the development of carbon reduction.Combined with scenario assumptions,this study predicted thefuture low-carbon development prospects of rail transit.The study confirmed that under the adjustment of energy structure,rail transit still had obvious carbon emission reduction advantages compared with other transportation modes.The results of this study would provide a scientific basis for the green development of low-carbon transportation and fully tap the carbon emission reduction potential of rail transit.关键词
