In order to create a beautiful China in which blue sky, clear water and beautiful scenery are shared, we must take concerted efforts of many forces to respond to the increasingly serious environmental problems. The procuratorial organ, based on its special functional status, has the power conferred by the Constitution and procedural law. And it often has more advantages than other subjects in environmental public interest litigation. However, in the current practice, the procuratorial organ has the only plaintiff in environmental administrative litigation, so it is not reasonable. As a legal supervisory organ, it can either take the lawsuit as a plaintiff or participate in the environmental administrative public interest litigation by supporting the prosecution. However, the initiation of it has a lack of appropriate design, and doesn’t have rules to make a the plaintiff rankings between prosecutors and environmental NGOs.

It will provide a useful reference for the enforcement of environmental administrative public interest litigation.
