Research on Key Driving Factors of Carbon Emissions in High-Speed Railway Stations Based on LMDI Model
To address the issue of unclear carbon emission patterns associated with various factors in high-speed railway stations and to make emission reduction measures more targeted,this study combines the data characteristics of factors influencing carbon emissions at Beijing Chaoyang Station,an LMDI carbon emission driving model and calculation method for railway stations were constructed.This approach allowed for an analysis of the carbon emissions driven by various factors in high-speed railway stations.The results indicate that the LMDI model effectively explains the carbon emissions attributed to different driving factors,with heating,ventilation,and air conditioning systems emerging as the primary contributor to carbon emissions at high-speed railway stations.Factors such as air conditioning systems,hot water and drinking water systems,lighting systems,escalator systems,and communication and information systems contribute positively to carbon emissions,while the replacement of building equipment,renewable energy systems,and building carbon sequestration systems have a suppression effect on emissions.Specifically,air conditioning systems and escalator systems are sensitive to increases in passenger flow,resulting in significant growth in carbon emissions over time.In contrast,carbon emissions from hot water and drinking water systems remain relatively stable,while renewable energy systems and building carbon sequestration systems are unaffected by passenger flow fluctuations,demonstrating consistent carbon reduction over three years.Notably,updating lighting system equipment leads to a marked decrease in carbon emissions.
