Abstract: University campuses,characterized by their high degree of organization and population density, serve as ideal subjects for studying carbon emissionquantification and carbon reduction strategies.Based on the greenhouse gas accounting framework of dlirect emissions, indirect emissions,and other indirect emissions, this paper establishes a methodology for campus carbon emission accounting.Taking a university campus as a case study,the paper systeematically calculates carbon emissions across various scopes and analyzes the characteristics of the carkon footprint.The results indicate that indirect carbon emissions constitute the primary source of campus oarbon emissions, with building electricity consumption contributing the largest share at 69.34%,highlighting the central role of energy conservation and consumption reduction in campus decarbonization strategies.Other indirect emissions (such as food consumption,transportation,and paper usage) acoount for approximately 25.90%,while direct emissions represent only 4.76%.In conclusion,this paper systematically explores decarbonization pathways for university campuses from the perspectives of buildiing energy efficiency improvement,behavioral guidance for faculty and students, optimization of campus energy structure,and carbon sink capacity enhancement, providing data support and policy references for the planning and implementation of zero-carbon campuses.
