Abstract: Addressing climate change is a legislative issue that should be given due attention in the Codification of Ecological and Environmental Law. At present, the response to climate change faces a pressing need for integration into the legal code-transitioning from international agreements to domestic legal systems, from policy discourse to legal expression, and from local regulations to central legislation. From a legislative logic standpoint, the codification of ecological and environmental law presents a crucial opportunity to achieve the goal of legalizing climate change response efforts, and it possesses the legislative character necessary to articulate relevant regulatory content. Given the broad scope involved, codifying the response to climate change is better suited to a decentralized rather than centralized legislative form. Accordingly, specific regulatory frameworks should be developed within various sections of the code-such as General Provisions, Pollution Control, Ecological Protection, and Green and Low-Carbon Development. These should respectively focus on articulating an overarching vision for addressing climate change, promoting coordinated governance efforts, functionally implementing climate targets, and guiding actions through the expression of core values.
