| Faced with the codification and implementation of the Ecological and Environmental Code, the systematization theory of environmental law needs refinement. Due to its structural difference from traditional branch laws, such as civil law, the systematization theories of traditional branch laws cannot be simply applied to environmental law. Instead, the systematization of environmental law must be adapted to the characteristics of domain law, including the ecological interconnectedness of regulatory objects, the interest symbiosis of regulatory goals, and the functional complementarity of regulatory means. It should pursue value completeness guided by the goal of sustainable development and normative coordination across the dimensions of “object-goal-means”. To derive environmental legal norms that carry complete values, the codification has shifted from relying on external sources to relying on internal sources, such as integrating existing environmental legal norms, abstracting common elements from specific norms, and transforming policies through normative interfaces. The implementation of the code must be grounded in the existing legal order and carried out through value-coherent interpretation. Building on internally derived norms, the codification has clarified the divisions between general and specific provisions, between internal and external systems, as well as between the code and individual laws under a “dual legal sources” mode. In implementing the code, we must further pursue coordination between general and specific norms that reflect the interconnectedness of regulatory objects, between internal and external norms that adapt to dynamic regulatory goals, as well as among external norms that integrate multiple regulatory means. |
