U.S. cannot protect its interests in the Arctic without ratifying UNCLOS

In May 2008, the United States signed the Ilulissat Declaration, an agreement among the five coastal states bordering the Arctic Ocean to abide by the customary law of the sea framework, even while it has not yet ratified the broadly accepted United Nation Convention on Law of the Sea (UNCLOS).¹⁰ While the Ilulissat Declaration establishes the body of law for managing the rights and obligations of states specifically within the Arctic Ocean, UNCLOS provides the primary mechanism for peaceful resolution of disputes and recognizes underwater territorial boundaries on the extended continental shelf.

Without ratification of UNCLOS, the United States lacks the legal power to contest the claims of other states in issues of overlapping maritime boundaries and the rights to resources on the continental shelf. This could give rise to what the international legal community terms excessive maritime claims. Therefore, unless the United States ratifies UNCLOS, the nation cannot properly protect its freedom of navigation as well as natural resource, energy and environmental interests in the Arctic.¹¹
