Abstract: The relationship between energy use and climate change is closely intertwined. After signing the Paris Agreement, China has actively adjusted its energy policies and promoted the transformation of its energygstructure with a legal mindset. China's "dual carbon" strategy has presented new challenges to the construction of energy ruleof law. Against this backdrop, China can draw on the experience of the European Union and combine its own national conditions to formulate policies that are in line with its development direction. Specific measures include incorporating energy proportion targets into the Renewable Energy Law, enacting the Climate Change Law, regulating the carbon trading system and market construction in legal form, and properly handling the relationship between energy law and climate law. Through these measures, it can ensure that energy rule of law not only meets energy demands but also effectively reduces greenhouse gas emissions, thereby promoting the optimization of the energy structure and the response to climate change through legal means.
