Define: International Environmental Law

International environmental law is a set of legal rules and principles that govern the relationship between states and the environment.

The main sources of international environmental law are treaties, customary international law, and general principles of law.

Some of the key international environmental treaties include the United Nations Framework Convention on Climate Change, the Convention on Biological Diversity, and the Montreal Protocol on Substances that Deplete the Ozone Layer.

The United Nations plays a key role in international environmental law by providing a forum for states to negotiate and adopt environmental treaties, and by supporting the implementation of those treaties.

The principle of common but differentiated responsibilities recognizes that all states have a responsibility to protect the environment, but that developed countries have a greater responsibility due to their historical contributions to environmental degradation and their greater capacity to address environmental problems.

Non-state actors, such as NGOs, businesses, and individuals, can play an important role in promoting and implementing international environmental law.

Some of the challenges facing international environmental law include the lack of enforcement mechanisms, the difficulty of addressing transboundary environmental problems, and the need to balance environmental protection with economic development.

International environmental law and human rights are closely linked, as environmental degradation can have a negative impact on the enjoyment of human rights such as the right to health, the right to a healthy environment, and the right to life.

Science plays a key role in international environmental law by providing the evidence and data needed to understand environmental problems and develop effective solutions.

Individuals and communities can participate in international environmental law by advocating for stronger environmental protections, participating in public consultations and hearings, and engaging with international organisations and processes.
