It is well know that the environmental public litigation plays an important role in enabling the public to participate in environmental protection and safeguard environmental rights and interests. The new Environmental Protection Law of the People's Republic of China (EPL) has relaxed the scope of environmental public litigation to actively promote environmental public litigation at the legislative level. However, the effect is not satisfactory. In China, to carry out environmental public litigation, there are many challenges to meet, for instance, the litigation subject is not well-defined, the capacity to action is restricted, the litigation rules are incomplete, and the supporting systems are still absent. Therefore, it is necessary to construct an environmental public litigation system that is well defined and supported.
