摘　　要：可持续消费与生产兼顾了环境保护、经济发展与社会公平,一直是全世界共同追求的目标。生命周期评价（LCA）因侧重于环境面分析而不能满足对于复杂产品的可持续评价。通过联合国环境署（UNEP）的生命周期可持续评价理论（LCSA）,探讨了产品可持续性评价的方法及应用。由于LCSA相关的评价框架尚不完整,通过文献探讨,分别制定了以清单分析和影响评估为基础的LCSA评价框架。以多晶硅光伏产品作为研究案例,经环境、经济、社会3个层面的可持续热点分析发现,硅晶片是多晶硅光伏电池板的改进重点。研究成果可作为企业管理者评价与分析产品可持续性的参考依据。Sustainable consumption and production taking account of environment protection,economic development and social justice are always the common goals of all over the world.Life cycle assessment（LCA）is a conventional analytical method focusing,however,on environmental aspects whilst hardly fulfilling the demands for assessing sustainability of complex products.Hence,it is attempted to explore a method of product sustainability assessment and its application through UNEP＇s life cycle sustainability assessment（LCSA）.As the LCSA is still in its infancy,the assessment framework has not yet been complete.Through literature searching,two evaluation frameworks were developed based on inventory-oriented analysis and impact-oriented assessment respectively.A product of polycrystalline silicon photovoltaic module was taken as a study case,and several sustainable hotspots were analysed in terms of environmental,economic and social aspects.It has indicated that silicon wafer would be the key that needed to be improved.The findings could be a reference to enterprise managers for evaluating and analysing the sustainability of products.
