基于碳足迹分析的高校校园碳排放研究

Research on Carbon Footprint of Colleges and Universities

高等院校因人口密度大,师生日常生活、教学及科研等活动耗能高,已成为城市内部高碳排放的代表性场所。以贵州理工学院为研究对象,调查分析了高校碳排放的3种代表性类型,分别是人员代谢、能源消耗以及日常生活消耗,每年对应排放碳量为4599 t、8798.66 t、1828.9 t,排放比例为30%、58%、12%,其中能源消耗排放碳量所占比例最高。针对了高等院校普遍存在低碳意识较差及资源浪费的问题,在此提出了以减排为主、增汇为辅的低碳实施方案,以期对构建绿色低碳校园、推动建设低碳城市、节约型社会提供参考。

Colleges and universities have become the representative places of high carbon emissions in cities because of their high population density and high energy consumption in daily life,and teaching and scientific research activities.Taking Guizhou Institute of Technology as the research object,this paper investigates and analyzes three representative types of carbon emissions in colleges and universities,namely,personnel metabolism,energy consumption and daily life consumption,with the corresponding annual carbon emissions of 4599 t,8798.66 t and 1828.9 t,and the emission proportions of 30%,58%and 12%,among which energy consumption accounts for the highest proportion of carbon emissions.Based on this,the paper puts forward the problems of poor low-carbon awareness and waste of resources in colleges and universities.On this basis,the low-carbon implementation plan of reducing emissions as the main and increasing sinks as the supplement is put forward,in order to provide a theoretical basis for building a green low-carbon campus and promoting the construction of low-carbon cities and a conservation-oriented society.
