Precious Metals, Rare Elements, and New Frontiers of the Law of the Sea
Strategic sectors such as energy transition, digital transformation, and the defense industry are becoming increasingly reliant on critical raw materials, including cobalt, nickel, copper, manganese, and rare earth elements. The expanding use of electric vehicle batteries, renewable energy systems, semiconductor technologies, and advanced defense platforms has elevated these resources beyond their traditional commercial value, embedding them within broader geopolitical and security considerations.
States are responding by seeking to secure access to terrestrial resources while simultaneously advancing policies aimed at diversifying supply chains, building strategic reserves, and reducing external dependencies. As land-based reserves face physical limitations and environmental constraints, attention is progressively shifting toward resources located in the deep ocean.
Within this framework, the United Nations Convention on the Law of the Sea establishes a differentiated legal regime. While coastal states exercise extensive rights over their territorial seas and exclusive economic zones, the international seabed beyond national jurisdiction is designated as the common heritage of humankind. Activities conducted in these areas are therefore framed through principles of international governance and shared benefit rather than sovereignty.
Polymetallic nodules and cobalt-rich formations found on the international seabed have emerged as focal points of global competition due to the strategic metals they contain. Access to these resources is increasingly viewed as closely linked to the long-term viability of the energy transition, industrial continuity, and strategic supply security.
Although the International Seabed Authority has developed a contractual system governing exploration activities in the Area, the regulatory framework applicable to commercial-scale exploitation remains under development. This evolving regulatory landscape contributes to legal uncertainty and heightens time-related pressures for both states and private actors positioning themselves in this emerging domain.
Developments in deep-sea mining also carry potential implications for maritime transport and global trade. The emergence of new logistical routes, specialized vessels, port infrastructure requirements, and environmental liability mechanisms is likely to expand the scope of issues addressed within maritime law and related regulatory regimes.
Competition centered on precious metals and rare elements is increasingly reshaping the contours of the law of the sea. The international seabed is understood as a complex legal and strategic space where energy policy, environmental protection, and trade considerations intersect.
