摘要：二氧化碳捕集利用与封存（CCUS）技术是国际认可的实现碳达峰碳中和目标所必须的负碳技术。CCUS技术减排的核心在于地质封存的安全性与实际地质封存量的核实、量化与验证，这是重点排放企业盘查实际减排量、确定碳配额、进入碳市场交易、标定碳足迹和获取政府补贴的重要依据。文章针对CCUS全流程项目，从直接排放、间接排放、全生命周期排放三种核查边界方式，分析了CO₂捕集、运输、注入与封存系统的核算边界，讨论了可能的排放和泄漏源，针对性地[l3]  提出了各系统的核算方法，构建适合我国的CCUS全流程碳排放核算方法体系。

Abstract: Carbon capture, utilization and storage (CCUS) technology is an internationally recognized negative carbon technology necessary to achieve carbon peak and carbon neutrality. The core of CCUS technology for emission reduction lies in the safety of geological sequestration and the verification, quantification and verification of the actual geological sequestration, which is an important basis for key emission enterprises to check the actual emission reduction, determine the carbon quota, enter the carbon market, calibrate the carbon footprint and obtain government subsidies. This paper analyzes the accounting boundary of CO₂ capture, transportation, injection and storage system from three verification boundary methods of direct emission, indirect emission and full life cycle emission for the whole process of CCUS project, and discusses the possible emission and leakage sources, following these, it proposes the accounting method of each system, and constructs the carbon emission accounting method system suitable for the whole process of CCUS in China.

Keywords: carbon capture, utilization and storage; carbon emission accounting; quantitative method; accounting boundary
