Objective Under the "dual carbon" goals, the trading of environmental interest products, as an environmental management measure based on the market mechanism, is crucial for promoting sustainable development. However, the concepts of domestic electricity-carbon environmental interest products have not been standardized and unified, and their related theories, policies and market mechanism designs also need to be improved. Therefore, this article conducts a comprehensive review and analysis on the development status, value verification, and existing problems of typical environmental interest products, and puts forward relevant suggestions for improving China's environmental interest product trading system.

Method First, focusing on typical environmental interest products such as green certificates, green electricity, carbon quota, and Chinese Certified Emission Reduction (CCER), the development status of the markets where these interest products are located, and sort out their policy evolutions, market scales and other situations. Second, conduct a comparative analysis of the ways to define the environmental value of new energy at home and abroad, summarize the four ways of verifying the value of China's current environmental interest products, and then put forward the design of the coupling mechanism for the future electricity, carbon and certificate markets. Finally, deeply discuss the key problems faced by the trading of environmental interest products, including decentralized product management, low environmental premium, and low international recognition.

Result Presenting targeted suggestions for the above problems, such as promoting the construction of the electricity-carbon-certificate market linkage mechanism, standardizing the environmental value definition standards, and improving the international recognition of green certificates.

Conclusion This article reviews the development status and trading mechanisms of typical environmental interest product markets, uncovers a series of problems currently faced by the markets, and needs to put forward policy suggestions from aspects such as market mechanisms, product values, and the international environment, so as to improve China's environmental interest product trading system, thereby enhancing the efficiency of environmental resource allocation, and finally helping the economy and the environment achieve a good situation of coordinated development.
