The Contribution of the International Tribunal for the Law of the Sea to the Protection of the Marine Environment
Abstract In its 25 years’ history, the International Tribunal for the Law of the Sea has dealt with a number of environmental cases. This has primarily occurred in the context of proceedings relating to the prescription of provisional measures and in advisory proceedings. This article explains how the Tribunal has reaffirmed and developed the basic environmental principles in Part XII of the Law of the Sea Convention, including the obligation to protect and preserve the marine environment, the precautionary approach, the duty to conduct environmental impact assessments, and the duty to cooperate, as well as the duty of due diligence, thereby contributing to the protection of the marine environment. Part XII of the Convention is a product of the 1970s and its provisions therefore reflect the state of international environmental law at that time. However, the Tribunal has interpreted and applied the aforementioned principles consistently with the contemporary state of international environmental law.
