基于生命周期的家电产品碳足迹计算方法研究

摘要

In the collection of a particular electrical appliances product mainstream production level based on the data of the database in GaBi greenhouse gas emissions relevant data, according to ISO 14040/44 of the life cycle assessment for the theoretical framework, using PAS2050 standards for electrical appliances product evaluation of carbon footprint research, the carbon footprint evaluation model is set. Taking the microwave oven as example, it discusses the different life cycle process on the carbon footprint. The results show that in use phase, the greenhouse gases emission of micro-wave is the largest.%在收集某款家电产品的主流生产水平数据的基础上，采用GaBi数据库中的温室气体排放相关数据，根据ISO 14040/44制定的生命周期评价理论框架，采用PAS2050准则开展家电产品碳足迹的研究，制订了碳足迹计算方法。以微波炉产品为例，讨论不同生命周期过程对碳足迹产生的影响。结果表明：微波炉在使用阶段的温室气体的排放量最大。
