Abstract: The relationship between energy use and climate change is inseparable. After the Paris Agreement, China has actively adjusted its energy policy and promoted the transformation of energy structure with the rule of law. China's "dual carbon" strategy poses a new challenge to the construction of energy rule of law. China can draw on the experience of the EU and formulate policies in line with its own national conditions. For example, the energy share target will be included in the Renewable Energy Law, the Climate Change Law will be promulgated, and the carbon trading system and market construction will be regulated in legal form. At the same time, the relationship between energy law and climate law needs to be properly addressed to ensure that the rule of law on energy meets energy demand while responsibly reducing greenhouse gas emissions. Through these measures, China's energy rule of law can not only meet its energy needs, but also responsibly reduce greenhouse gas emissions, and promote the optimization of energy structure and climate change response by means of law.
