基于生命周期评价的快递碳足迹核算

Accounting of Express Delivery Carbon Footprint Based on Life Cycle Assessment

在对快递碳足迹的相关研究进行综述的基础上,基于生命周期评价原理,将快递生命周期碳排放源主要分为运输环节消耗的燃油、城市内运营管理和中心分拣建包(集包)环节消耗的电能以及包装环节消耗的快递包装及耗材三个方面,运用排放因子法构建了快递碳足迹核算模型,并采用案例分析法核算快递生命周期各个阶段的碳排放量,分析各个阶段的碳排放量大小,从而制定有针对性的措施利于快递服务企业实现节能减排。研究结果显示,在单个快件生命周期的碳足迹中,快递包装产生的碳排放比例最大,电能次之,燃油最小。

Based on a review of related researches on the carbon footprint of express delivery,and according to the principle of life cycle assessment,we divided the carbon emission sources of express delivery in a life circle mainly into fuel consumed in transportation links,electricity consumed in intra-city operation management and distribution center package sorting links,and the packaging materials and consumables used in the packaging process.Next,using the emission factor method,we constructed the express delivery carbon footprint accounting model,and had a case analysis to calculate the carbon emissions at each life cycle stage of the express delivery business,by which we could analyze the carbon emissions in each stage and formulate the measures to help express service companies achieve energy conservation and emission reduction with a clear target.The result of the study showed that,in the life circle of a single express parcel,packaging took up the largest proportion of carbon emissions,followed by electricity,and then by fuel.
