Policymakers are locked in a fierce debate over whether deep-sea mining is necessary or safe. A Canadian firm, The Metals Company, recently completed a successful pilot run nearly 13,000 feet down in the Pacific, harvesting potato-sized nodules rich in copper, manganese, cobalt, and nickel. The company aims to secure permits for commercial extraction over 65,000 square kilometers, targeting over 600 million metric tons of these minerals.

This push occurs against a backdrop of soaring demand driven by the green transition. The International Energy Agency projects that scaling renewable energy could quadruple demand for critical minerals by 2040, creating potential shortages as early as 2035. While proponents argue terrestrial mines are insufficient, critics, including 40 countries led by Palau, demand a moratorium due to environmental risks.

The International Seabed Authority is drafting rules, but talks stalled in July 2025 with key issues unresolved, including ecological impact monitoring. Nauru is exploring a loophole to bypass the authority, and The Metals Company has applied for a US permit, highlighting the urgent need for clarity before mining potentially starts this year.
