产品碳足迹作为产品的环境属性之一，可以直观地披露产品生命周期内温室气体排放信息，有助于政府、组织或个人真正了解各项生产、生活活动对气候变化的影响，可以引导绿色消费、协助企业挖掘减排潜力，也是全球应对气候变化和国际贸易的重要博弈领域。开展基于生命周期评价理论的产品碳足迹核算，在为组织打造差异化产品、提高产品低碳竞争力提供有力支撑的同时，也能为制订、实施贯穿全产业链的协同降碳管理计划和措施提供规范、透明的技术手段。
The global climate crisis and climate change caused by human activities has become a major issue faced by governments and societies worldwide. Product carbon footprint is widely adopted as one of the environmental attributes of products that can visually display greenhouse gas emission information. Accurate calculation of product carbon footprint helps governments，organizations，or individuals truly understand the impact of various production and lifestyle activities on climate change. This understanding guides the development of product carbon footprint information based on the theory of full life cycle assessment，providing strong support for organizations to create differentiated products and improve their carbon reduction competitiveness. Furthermore，it offers standardized and transparent technical means for formulating and implementing carbon reduction management plans and measures throughout the entire industrial chain.
