The false promise of deep-sea mining. [PDF]

NPJ Ocean Sustain
Deep-sea mining of the international seabed could begin soon, despite concerns about its ecological consequences. We join others calling for a ban on international seabed mining, but for a different reason: it is a multi-billion-dollar solution to problems that do not exist.

Deep-sea mining: Superficial riches, deep hidden costs

Abstract Deep-sea mining (DSM) is promoted as a solution to secure minerals critical for a rapid energy transition1,2, yet its full economic, environmental, and social implications remain poorly quantified3–5. Here, we conduct arguably the most comprehensive cost-benefit analysis (CBA) of DSM to date, compiling and using data from publicly ...
