Abstract: China has become the world’s largest producer and user of renewable energy, and promoting international cooperation in green energy is an inherent requirement for China’s practice of fulfilling the concept of green development and promoting the construction of an ecological civilization and in building a community with a shared future for mankind. International cooperation in global green energy is booming with more than 130 countries setting their goals of carbon neutrality. In international green energy cooperation, the rule of law is an important way to regulate cooperation procedures, resolve cooperation disputes and protect cooperation results. However, in the practice of international cooperation, there exist problems such as the lack of domestic legal basis to promote international cooperation, the difficulty in balancing the flexibility and standardization of international cooperation, the unclear policies of the third party leading to conflicts of interest and the absence of the relief system leading to disputes that are difficult to resolve. It is suggested to consolidate the domestic legal basis for international cooperation in green energy, to build a "soft and hard" international cooperation law system, to improve the third-party policy identification mechanism based on multilateral platforms, and to continue to promote the construction of international environmental dispute settlement platform.

Key words: green energy, carbon neutrality, legal barrier, domestic law, international cooperation law system
