回顾和梳理了自愿减排议程的相关制度与市场构建，针对已有海洋碳汇研究存在的问题，阐释了自然界碳平衡状态下碳汇与人类经济活动产生碳汇的本质区别和自愿减排机制下海洋碳汇的本质，提出“可信用化碳汇”概念，认为海洋碳汇是人类基于与海洋相关的自然解决方案而从事的以碳移除为目的的全部经济活动，方法学缺失以及蓝碳项目投资热情不足是制约海洋碳汇市场发展的根本原因，已有研究混淆了自然碳汇与人为碳汇的区别，侧重于以碳汇机理与效率测度的海洋碳汇自然科学研究，忽视了经济学视角下可交易碳汇的内涵、要素与机制设计，因此，基于《巴黎协定》第6.4条的海洋碳汇市场构建应遵循“海洋碳汇项目-海洋碳汇方法学-海洋碳汇核证-海洋碳汇交易”逻辑框架。

This paper reviews and sorts out the relevant systems and market construction of the voluntary emission reduction agenda, addresses the existing problems in marine carbon sequestration research, explains the essential differences between carbon sequestration under the natural carbon balance state and carbon sequestration generated by human economic activities, as well as the essence of marine carbon sequestration under the voluntary emission reduction mechanism, and innovatively proposes the concept of “creditable carbon sequestration”. This paper believes that marine carbon sequestration refers to all economic activities aimed at carbon removal conducted by humans based on natural solutions related to the ocean. The lack of methodologies and insufficient investment enthusiasm for blue carbon projects are the fundamental reasons restricting the development of the marine carbon sequestration market. Existing research has confused the differences between natural carbon sequestration and anthropogenic carbon sequestration, focusing on natural science research on marine carbon sequestration mechanisms and efficiency measurement, while ignoring the connotation, elements, and mechanism design of tradable carbon sequestration from an economic perspective. Therefore, the construction of the marine carbon sequestration market based on Article 6.4 of the Paris Agreement should follow the logical framework of “marine carbon sequestration projects-marine carbon sequestration methodologies-marine carbon sequestration verification-marine carbon sequestration trading”.
