京津冀地区铁路运输碳排放特征和减排潜力研究
Research on Carbon Emission Characteristics and Emission Reduction Potential of Railway Transport in Beijing-Tianjin-Hebei Region
摘要
Abstract
Energy conservation and carbon reduction in the railway sector are of great significance in the sustainable development of the transportation industry.To address key issues such as high railway traffic volume and significant emissions in the Beijing-Tianjin-Hebei region,this study calculated the carbon emissions from railway operations based on the IPCC National Greenhouse Gas Inventory Guidelines.It analyzed the distribution of energy consumption and employed Geographic Information System(GIS)analysis to examine the characteristics of railway carbon emissions and the emission reduction potential of major technologies.The results showed that the total carbon emissions from railwaytransport in the Beijing-Tianjin-Hebei region were 3.882 6,3.503 3,and 3.503 1 million tons in 2019,2020,and 2021,respectively.Direct carbon emissions declined annually,from 660 000 tons in 2019 to 561 000 tons in 2020,reflecting a reduction of 1％.Due to the COVID-19 pandemic,indirect carbon emissions dropped from 3.222 million tons to approximately 2.9 million tons,but their proportion of total emissions increased annually,reaching an average proportion of 84％.Electricity,thermal energy,and diesel fuel are the primary energy sources for railway transport in the Beijing-Tianjin-Hebei region.Major sources of carbon emission included locomotive depots,maintenance and operation support departments,and passenger stations.Electricity and diesel consumption were concentrated in locomotive depots,while thermal energy was mainly used in maintenance and operation support departments.Natural gas from gas fields and alcohol-based fuels were widely applied in vehicle depots,whereas gasoline,biomass fuel,liquefied petroleum gas,and anthracite coal were partially used in engineering maintenance sectors.Bituminous coal was primarily consumed by the railway operation sector.The ranking of carbon emission intensity was Beijing＞Tianjin＞Hebei,closely correlated with transport turnover.The results of sensitivity analysis showed that the electricity emission factor had a significantly greater impact on railway carbon emissions than diesel consumption and thermal energy use.By implementing technical substitutions in railway passenger stations,it was found that replacing coal-fired power with rooftop photovoltaic power generation in the Beijing-Tianjin-Hebei region could reduce emissions by 763 000 tons of CO2 equivalent(tCO2e),while the application of energy management systems could reduce emissions by 14 000 tCO2e.These findings suggest that promoting new energy technologies and adopting intelligent management platforms are key pathways to achieving railway carbon neutrality.关键词
