Investor briefing: Deep-Sea Mining – Risks, Realities & the Road Ahead

  • Date: 25/06/2025
  • Time: 16:00-17:00 (CET)
  • Location: Online

This one-hour webinar will provide an up-to-date investor briefing on deep-sea mining, its risks and regulatory developments, and the role investors can play. It will review recent news, including proposals from the United States to unilaterally mine in international waters.

Concern over the secure supply of minerals is increasing, including those required for the global energy transition, critical for electric vehicles, renewable energy infrastructure, and battery storage. Today, these materials are primarily sourced through terrestrial mining, often in biodiverse regions and Indigenous territories. This has led to well-documented environmental and human rights concerns, including deforestation, polluted waterways, displacement, and social conflict.

One proposed alternative lies far from land: the deep sea. Manganese nodules located on the ocean floor contain key materials such as cobalt, nickel, manganese, and copper. Advocates claim that deep-sea mining could reduce the pressure on terrestrial ecosystems, offering a solution that could help avoid deforestation and other land-based harms. Others, such as the European Academies Science Advisory Council, say that statements claiming that deep-sea mining is needed for the green transition or is less environmentally damaging than terrestrial mining for the same metals are misleading.

The deep ocean plays a vital role in maintaining global climate stability, biodiversity, and ecosystem services. Its ecosystems are poorly understood and potentially highly vulnerable to industrial disruption. While the need for minerals is urgent, many stakeholders—including investors—call for greater investment in improving the social and environmental standards of terrestrial mining operations, circular economy solutions and for comprehensive research into the environmental, social and economic risks of deep sea mining before commercial activity begins.

Programma Deep Sea Mining webinar

We are pleased to be joined by two leading experts:

  • Andrew Whitmore, Finance Advocacy Officer of the Deep Sea Mining Campaign
    Andy has worked on the issues of mining & affected communities since becoming a founder member of the Minewatch collective in the late 1980s. He also helped to found London Mining Network, where he is currently co-chair of the organisation, and was managing editor of the Mines and Communities website. Andy has an MA in Development Studies from the School of Oriental and African Studies (University of London) and is the author of “A Material Transition” and “Unearthing Justice: a global approach to transition minerals”, as well as various articles on similar issues.
  • Matthew Gianni, Co-founder, Political and Policy Advisor of the Deep Sea Conservation Coalition
    Matthew Gianni is a co-founder of the Deep Sea Conservation Coalition (DSCC) and serves as the Coalition’s political and policy advisor. He has co-authored a number of papers and reports on deep-sea mining, deep-sea fishing and international oceans governance. He has been a formal partner in the EU-funded deep-sea science projects Atlantic, Atlas and the MIDAS Project, the latter focused exclusively on investigating the potential environmental impacts of deep-sea mining. He has participated in meetings of the International Seabed Authority (ISA) for the past 11 years and has made many presentations on the topic to university seminars, ISA workshops, law and policy institutes, government officials, science organisations, regional fisheries treaty organisations and others.
