运用投入-产出混合生命周期评价法的基本原理和核心EIO-LCA模型,探索了混合模型微观数据在宏观数据背景中的嵌入方法和路径,建立了酒店经济-环境系统碳足迹测评混合模型,并实证于全国八家高星级酒店。研究结果表明:八家高星级酒店三个范围碳足迹的比例均值分别约为0.46%、18.79%、80.75%;单位产值均值分别约10.78kg CO2eq./万元、488.9kg CO2eq./万元、2226.64kg CO2eq./万元。与范围3间接碳足迹直接相关的GHG排放“热点”行业中,比例最高的是饮食类约15.97%,其次是交通类约11.02%,用品类约10.37%,经营管理类约9.91%。范围2和范围3碳足迹存在更大减排空间。
By using the basic principles and core EIO-LCA model of input-output hybrid life cycle assessment method, this paper explores the embedded method and path of hybrid model micro data in macro data background and establishes a hybrid model of hotel eco-environment system carbon footprint evaluation. And empirical eight high-star hotel in the country. The results show that the average carbon footprint of the three high-star hotels is 0.46%, 18.79% and 80.75% respectively. The average unit output value is about 10.78kg CO2eq./equipment and 488.9kg CO2eq./equipment respectively , 2226.64kg CO2eq./ ten thousand yuan. GHG emissions directly related to the Scope 3 indirect carbon footprint were the highest in the “hot spots” industries, accounting for about 15.97% of the total food and beverage categories, followed by 11.02% for transportation, 10.37% for supplies and 9.91% for management. There is room for greater reductions in Scope 2 and Scope 3 carbon footprint.
