摘　　要：建立数据可信、可追溯且国际互认的皮革化学品生命周期评价(LCA)本土数据库对于准确核算我国皮革产品的潜在环境影响至关重要。本研究系统分析了国内外皮革化学品的LCA研究案例及相关数据库现状,制定了皮革化学品LCA本土数据库的建设规划,并提出了适用的LCA框架。研究表明,目前尚缺乏全面的皮革化学品LCA数据库,这制约了皮革环境足迹(含碳足迹)的准确评估。根据皮革化学品的使用量及其环境影响,建议将其数据库建设划分为三个等级:Ⅰ级(鞣剂、加脂剂、涂饰剂)、Ⅱ级(表面活性剂、酶制剂、染料)和Ⅲ级(浸水助剂等皮革专用助剂)。基于ISO 14040、ISO 14044等标准,确定皮革化学品的研究范围应为“从摇篮到大门”的系统边界,涵盖化学品生产、包装和运输等全过程。研究为皮革化学品LCA数据库的建设提供了系统指导,有助于推动皮革行业碳足迹管理体系的建设。Establishing a credible,traceable,and internationally recognized life cycle assessment(LCA)database for leather chemicals is crucial for accurately assessing the potential environmental impacts of China's leather products.This study systematically analyzed domestic and international LCA case studies of leather chemicals and assessed the current status of related databases.Based on this analysis,we developed a plan for constructing a domestic LCA database for leather chemicals and proposed a suitable LCA framework.The research revealed a lack of comprehensive LCA databases for leather chemicals.This limits the accurate assessment of the environmental footprint of leather,including its carbon footprint.We recommend a three-tiered approach for database construction,based on the usage and environmental impacts of leather chemicals:Level I(tanning agents,fatliquors,and finishing agents),Level II(surfactants,enzyme preparations,and dyes),and Level III(soaking auxiliaries and other leather-specific auxiliaries).Guided by ISO 14040 and ISO 14044,the study scope of leather chemicals should be defined within a"cradle-to-gate"system boundary,encompassing production,packaging,and transportation of leather chemicals.This study provides systematic guidance for constructing an LCA database for leather chemicals,supporting the establishment of a carbon footprint management system in the leather industry.
