基于生命周期的家电产品碳排放计算方法研究

Research on computing method of carbon emission of home appliances products based on LCA

文章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,依据ISO 14040制定的生命周期评价理论框架,采用PAS 2050准则开展家电产品碳排放评估的研究,制订了碳排放评估模型;以豆浆机产品为例,讨论不同生命周期过程对碳排放产生的影响。结果表明,豆浆机在使用阶段的温室气体的排放量最大。

Based on the data collection of the mainstream production level of a particular electrical home appliance product, using the relevant data of the greenhouse gas emissions in GaBi database and the theoretical framework of the life cycle assessment（LCA） based on ISO 14040, the carbon emission of electrical home appliances products isl evaluated according to PAS 2050 standard and a model for car- bon emission evaluation is set up. Taking the soya-bean milk machine as an example, the influence of different life cycle process on the carbon emission is studied. The results show that the emission of greenhouse gases is largest when the soya-bean milk machine is in use.
