To confront the urgent challenges of global climate change, achieving dual carbon goals is now central to China’s economic and social development. In this context, integrating the electricity and carbon markets is essential for promoting the green transformation of the energy system and accelerating the transition to a low-carbon economy. This study examines the integration between the green electricity market, green electricity certificate (GEC) market, and carbon market. It provides an in-depth analysis of current coupling policies and practices, identifying issues like inefficient price transmission and ineffective integration of environmental rights products. The study proposes three recommendations for market coupling: improving price transmission mechanisms, enhancing the integration of environmental rights products, and promoting international mutual recognition of green electricity consumption. These recommendations aim to promote the coordinated development of the green electricity and carbon markets, advancing the construction of a new electricity system.
