U.S. failure to ratify UNCLOS will leave U.S. commercial mining and energy interests without legal protection

Offshore oil and natural gas exploration along the extended continental shelf – an area beyond the 200-nautical-mile EEZ – is expected to increase U.S. reserves over the next decade. However, the United States cannot secure internationally recognized sovereign rights to those resources unless it ratifies LOSC. While the United States enjoys national jurisdiction over living and non-living resources above and below the seabed out to 200 nautical miles, claims to resources beyond the EEZ must be formally made to the U.N. Commission on the Limits of the Continental Shelf, the international body established by LOSC for parties to adjudicate claims to the extended continental shelf. Without the United States ratifying LOSC, U.S. companies operating beyond the EEZ would be considered on the high seas and beyond the formal legal protection of the United States. As a result, offshore drilling companies have increasingly expressed their concern about the lack of legal protections afforded to U.S. companies and have indicated a reluctance to assume significant risk in operating in areas beyond U.S. jurisdiction. In short, U.S. failure to ratify LOSC could have a chilling effect on commercial resource exploration and exploitation on the extended continental shelf.
