构建CCUS项目全流程温室气体核算体系是大范围推广CCUS技术实现净减排的重要前提，也是应对国际可持续披露准则(ISSB标准)的有效措施。鉴于此，分别从CCUS运营的“时间边界、物理边界、核算边界”入手，聚焦“捕集阶段-运输阶段-利用阶段-封存阶段”等核心环节，嵌入范围1、范围2和范围3温室气体核算方法，试图构建CCUS建设运营周期内全范围核算的理论体系，并结合现实中CCUS运营的数据可获取性，构建了CCUS项目全流程温室气体核算指标体系。进一步，在实际核算过程中，结合国际ISSB标准的要求和温室气体核算的数据指标，指出中国CCUS项目运营过程中全范围核算的关键步骤和有效措施。研究结论为完善国内温室气体的全范围核算奠定基础，尤其是对CCUS项目净减排贡献的核定具有重要的参考价值。
Abstract：The construction of a full-chain greenhouse gas accounting system for CCUS projects is an important aspect of large-scale promotion of CCUS technology to achieve net emission reduction, and it is also an effective measure to cope with the compliant operation requirements such as the latest International Sustainability Disclosure Board(ISSB) standards. In view of this, this paper starts from the "time boundary-physical boundary-accounting boundary" analysis of CCUS operation, focuses on the core links such as "capture stage-transportation stage-utilization stage-storage stage", embeds Scope 1, Scope 2 and Scope 3 greenhouse gas accounting methods, tries to construct a theoretical system of full-chain accounting in the CCUS construction and operation cycle, and constructs a life-cycle greenhouse gas accounting index system for CCUS projects based on the data availability of CCUS operation in reality. Furthermore, in the actual accounting process, this paper also points out the key steps and effective measures of full-chain accounting in the operation of CCUS projects in China are based on the requirements of international ISSB standards and the data indicators of greenhouse gas accounting. The research in this paper lays a foundation for improving the full-chain accounting of greenhouse gases in China, especially for the verification of the net emission reduction contribution of CCUS projects.
