A Mining Startup’s Rush for Underwater Metals Comes With Deep Risks

DeepGreen built a nearly $3 billion valuation on the dream of gently excavating the ocean floor. Now environmentalists want to block its plans to go public.

In an extraordinary display of DeepGreen’s influence, the Pacific island nation Nauru broke UN protocol in February 2019 by ceding its seat to the company’s chief executive, Gerard Barron, at a meeting of the International Seabed Authority Council.

A seabed mining startup, DeepGreen Metals Inc., has successfully sold itself to investors as a game-changing source of minerals to make electric car batteries that can be obtained in abundance—and at great profit—while minimizing the environmental destruction of mining on land.

But there’s strong scientific evidence that the seabed targeted for mining is in fact one of the most biodiverse places on the planet—and increasing reason to worry about DeepGreen’s tantalizing promises. Bloomberg Green’s examination of corporate and legal filings, regulatory records and other documents raises questions about DeepGreen’s business plans. Previously undisclosed agreements with developing island states in the South Pacific show the company’s political and financial leverage over its partners, who are dependent on its expertise to exploit their seabed resources and obligated to ensure DeepGreen’s compliance with international environmental regulations.
