What is the basic system of environmental law that directly embodies the principle of prevention?

the basic system of environmental law that directly embodies the principle of prevention is the three simultaneities system.

the "three simultaneities" system is the earliest environmental management system in China. The pollution prevention facilities in the project shall be designed, constructed and put into use at the same time as the main project. Before the formal construction of a construction project, the construction unit must submit the chapter on environmental protection in the preliminary design to the competent administrative department of environmental protection. In the chapter of environmental protection, we must implement the measures to prevent and control environmental pollution and ecological damage and the investment budget of environmental protection facilities. The chapter on environmental protection can only be included in the construction plan and put into construction after examination and approval. After the completion of the main project of a construction project, it is necessary to carry out trial production, and the supporting environmental protection facilities must be put into trial operation at the same time as the main project.

after the completion of a construction project, the construction unit shall apply to the competent administrative department of environmental protection that examines and approves the environmental impact report of the construction project for the completion acceptance of the environmental protection facilities that need to be built for the construction project. The completion acceptance of environmental protection facilities shall be carried out at the same time as the completion acceptance of the main project. For a construction project that needs trial production, the construction unit shall, within 3 months from the date when the construction project is put into trial production, apply to the competent administrative department of environmental protection for approval of the environmental impact report of the construction project for acceptance of the environmental protection facilities supporting the construction project.

The total emission control targets of key pollutants are issued by the State Council, and are decomposed and implemented by the people's governments of provinces, autonomous regions and municipalities directly under the Central Government.
