摘　　要：[目的]通过对2种不同材料的侧墙板的碳足迹进行研究,探索其内装产品碳足迹的核算方法,以期指导设计师实现低碳设计。[方法]选取轨道车辆内装PC(聚碳酸酯)材料侧墙板及玻璃钢侧墙板为研究对象,按照英国标准协会发布的PAS 2050:2011《商品和服务在生命周期温室气体排放的评价规范》的全生命周期评价方法,核算了2种不同材料的侧墙板生命周期各阶段的碳足迹及贡献度。[结果及结论]在系统边界范围内,玻璃钢侧墙板碳足迹核算结果比PC侧墙板碳足迹核算结果大,且2种侧墙板在原材料获取阶段碳足迹的贡献度最大。在满足车辆性能前提下,选择碳足迹更低的PC侧墙板,更有利于整车降碳。[Objective]By studying the carbon footprint of two kinds of side wallboard made of different materials for rail vehicles,the accounting method for the carbon footprint of interior products is explored to guide designers in achieving low-carbon design.[Method]Side wallboards made of PC(polycarbonate)and FRP(fiberglass-reinforced plastic)for rail vehicle interiors are selected as research objects.Following the lifecycle assessment method outlined in PAS 2050:2011′Specification for the Assessment of the Life Cycle Greenhouse Gas Emissions of Goods and Services′,published by the British Standards Institution,the carbon footprints and contributions of the two different materials′side wallboards at each lifecycle stage are calculated.[Result&Conclusion]Within the defined system boundaries,the carbon footprint of FRP side wallboard is greater than that of PC one,with the highest contribution to the carbon footprint observed during the raw material acquisition stage for both types of wallboards.Under the premise of meeting vehicle performance requirements,selecting PC side wallboards with a lower carbon footprint is more conducive to overall vehicle decarbonization.
