中文摘要：

温室气体排放引起的全球变暖已经成为人类面临的重大环境问题。碳足迹基于生命周期评价,对服务或商品所产生的温室气体排放量进行测度。将碳足迹引入旅游研究,对旅游业的重要组成部分——酒店住宿产品进行生命周期评价,构建了酒店住宿产品碳足迹计算模型,并实证于昆明市6家四星级酒店。结果表明：酒店住宿产品碳足迹主要来自运营期,约占整个生命周期的72.71%;来源包括能源消耗、垃圾释放和制冷剂泄露3个方面,其中直接能源消耗约占60.98%;主要影响因素是消耗量和排放系数,酒店规模对碳足迹的影响受到了环境温度等其他因素的扰动,作用并不明显。研究有利于寻找在旅游产品设计、生产和供应等过程中降低温室气体排放的机会,亦可为旅游业的＂节能减排＂提供理论支撑。

英文摘要：

Global warming caused by greenhouse gas emission has become an important environmental issue facing humanity. Carbon footprint, based on life cycle assessment, measures CHG emission generated from services and commodities. By introducing carbon footprint into tourism study, the paper conducts a LCA of hotel accommodation services, which is an important part of tourism industry and develops a calculation model to study carbon footprint. An empirical study is carried out in six four-star hotels in Kunming. The results show that carbon footprint is mainly generated in the operation stage, accounting for about 72.71% of total life cycle, including energy consumption, waste release and refrigerant leakage, among which direct energy consumption accounts for 60.98%. The major influencing factors are consumption volume and emission coefficient. The scale of a hotel does not have obvious impact on carbon footprint. The study is conducive to searching opportunities for reducing the emission of greenhouse gas in the process of designing, producing and supplying tourism products and providing theoretical support for ＂energy conservation and emission reduction＂ in tourism industry.
