摘要:为准确量化与评价纺织产品生命周期内的碳足迹,详细解析了PAS 2395:2014纺织产品全生命周期温室气体排放评价规范。结果表明:清晰设定核算边界是纺织产品生命周期內碳足迹核算的先决条件;核算数据的质量直接影响纺织产品碳足迹核算结果的不确定度;共生产品碳排放量的分配根据产品特性是否相似而分别选择产量或经济价值作为拆分依据;碳足迹核算结果的评价可以进行全生命周期阶段的评价,也可以针对生命周期中某一阶段进行重点评价,以减少产品的碳足迹。

The results showed that system boundary was the prerequisite for life cycle carbon footprint accounting. The data quality directly affected the uncertainty of the carbon footprint accounting result. The allocation of carbon emissions shall be based on mass or economic value according to the characteristics of coproducts. The carbon footprint assessment can be applied on the whole life cycle of textile product as well as on a specific stage in order to reduce the carbon footprint.
