摘要
推进产品碳足迹核算体系本土化构建与“双碳”战略深度融合,是应对全球气候变化、实现绿色发展的关键路径。文章系统分析国际产品碳足迹核算体系发展现状,阐述生命周期评价(life cycle assessment,LCA)方法在我国的理论和实践创新问题,提出构建具备中国特色的“四位一体”产品碳足迹核算方法论体系,涵盖模型方法、数据体系、标准规范、核算认证要素。在模型方法层面,提出分层分级碳足迹建模、用电间接碳排放时空动态核算、能源碳负荷分配关键技术;在数据体系层面,提出数据分级溯源与实景背景数据转化技术,设计本土化背景数据库构建路径;在标准规范层面,明确分行业产品种类规则(product category rule,PCR)研制路径,强化政策与标准衔接协同;在核算认证层面,点明产品碳足迹标识认证制度建设关键环节,并探索国际互认路径。最后,基于“四位一体”方法论体系,提出加强产品碳足迹管理体系构建的重点措施。
Integrating the development of a localized carbon footprint of products(CFP)accounting system with China’s"Dual Carbon"strategy is crucial for achieving industrial addressing global climate change and green development.This paper reviews the development of the global CFP accounting system,and elaborates on the theoretical and practical innovation issues of the Life Cycle Assessment(LCA)method in China.To address these issues,this paper proposes an innovative"Four-in-One"methodological framework for CFP accounting with Chinese characteristics.The framework encompasses four core elements:modeling methods,data systems,standard specifications,and accounting certification.1)Modeling Methods:this study develops a hierarchical carbon footprint modeling approach,introduces spatiotemporal dynamic accounting for indirect carbon emissions from electricity use,and employs energy carbon load allocation techniques to enhance accuracy and applicability.2)Data Systems:Innovative data grading and traceability technologies,along with real-scenario background data conversion methods,are proposed to support the construction of localized background databases.3)Standard Specifications:the study clarifies pathways for developing industry-specific Product Category Rules(PCR)and strengthens the synergy between policies and standards to ensure systematic implementation.4)Accounting and Certification:the linkage between carbon footprint labeling,certification and verification is elucidated,while pathways for international mutual recognition are explored to ensure alignment with global standards.Finally,with the goal of the full implementation of the"Four-in-One"system,core measures for strengthening the product carbon footprint management system are put forward.
