This article examines the so-called “Arctic exception,” Article 234 of the 1982 UN Convention on the Law of the Sea. Article 234 is intended to give the coastal state of ice-covered sea areas the necessary powers to prevent, reduce, and control vessel source pollution, which poses a particular risk to the highly sensitive Arctic marine environment. The aim of this article is to present a thorough interpretation of Article 234 in order to eventually evaluate the provision’s significance for Arctic navigation,specifically in the Canadian Arctic and the Northwest Passage.
