1/ Although the concept of environmental rule of law is relatively new in the doctrine of environmental law, it has already contributed to the development of standards of emerging sustainable development law. Its genesis can be traced in the UNEP Governing Body Decision 27/9 on Advancing Justice, Governance and Law for the Environmental Sustainability which refers to the growing significance of the rule of law in the context of socio-economic development in the process of achieving the objectives and goals of sustainable development.
The term environmental rule of law refers to the environmental-legal space of the general notion of the term “rule of law.” In the light of environmental conservation and protection, it describes basic requirements, such as ensuring adherence to the principles of supremacy of law, equality before the law, accountability to the law, fairness in the application of the law, separation of powers, participation in decision-making, legal certainty, avoidance of arbitrariness, and procedural and legal transparency in the field of the environment. These standards help societies experiencing social and economic consequences of environmental degradation, overcome multifarious costs resulting from development, which does not respect environmental requirements and therefore hamper the process of achieving sustainable development objectives. In this context, the environmental rule of law should be perceived as a new paradigm at all levels of environmental governance, decision-making, and justice.
One can say that the environmental rule of law reflects universal values of modern society providing the foundation for environmental rights and duties, and forms one of the most important pillars of environmental governance and justice constituting the legal basis for achieving sustainable development goals. As it has been rightly pointed out in the International Union for Conservation of Nature World Declaration on the Environmental Rule of Law of 2016, without the environmental rule of law, environmental governance, conservation, and protection may be arbitrary subjective, and unpredictable.[3] Therefore, the principle of the environmental rule of law should be considered as a basis before adopting any document and acting on environmental policy and law.
