Legal Challenge Launched Against Government's Deep-Sea Mining License Approval
Environmental advocacy has taken a significant turn with the launch of a legal challenge by a prominent environmental organization against the United Kingdom government. The challenge specifically targets the government's decision to grant exploration licenses for deep-sea mining in the Pacific Ocean to a company identified by critics as having a questionable reputation. The organization expresses deep concern that the transfer of these licenses could pave the way for environmentally damaging deep-sea mining operations, posing a substantial threat to marine ecosystems. This action is also framed as being inconsistent with the government's previously stated support for a moratorium on this potentially destructive industry.
The legal action initiated by the environmental group represents the initial step in a judicial review process. A formal Pre-Action Protocol letter has been submitted, outlining the grounds for the challenge. This letter asserts that the Business Secretary's decision to transfer the exploration licenses may be in violation of both international and domestic legal frameworks. The licenses in question cover a vast area within the Clarion-Clipperton Zone of the Pacific Ocean, a region stretching 133,000 square kilometers – an expanse larger than the entire country of England. This zone is characterized by the presence of polymetallic nodules, which contain valuable metals sought after by a limited number of companies for future extraction.
However, the Clarion-Clipperton Zone is also a critical habitat for a diverse array of marine life, including whales, dolphins, and numerous unique deep-sea species. Recent scientific research conducted by the Natural History Museum has indicated that even exploratory mining activities can lead to a significant reduction – nearly 40 percent, according to the study – in the populations of seafloor animals. This highlights the potential for substantial and lasting ecological damage associated with deep-sea mining.
For several years, the exploration licenses for these areas were held by UK Seabed Resources Ltd (UKSRL), a company with a complex ownership history involving a series of international firms, notably including the US defense contractor Lockheed Martin. More recently, the licenses were under the control of a smaller Norwegian company named Loke Marine Minerals AS, which ceased operations and went into liquidation in April 2025. The government’s continued backing of these exploration licenses is seen as a contradiction to its own public pronouncements, which have consistently advocated for a moratorium on deep-sea mining until more comprehensive scientific evidence is available to fully assess the impact on marine ecosystems and robust environmental regulations are established by the International Seabed Authority (ISA).
The company now holding the licenses, Glomar Minerals, is officially registered in the UK but is primarily owned and managed by entities and individuals based in other countries. Raphael Isaac Meir Diamond is identified as the company’s principal controller. Mr. Diamond, a US resident, is also the founder and executive chairman of SAFE, a US lobbying group that publicly supported President Trump’s executive order concerning deep-sea mining. This order is widely viewed as being in violation of established international law. The growing global concern surrounding deep-sea mining is reflected in the widespread opposition from over 900 scientists and policy experts, along with the support of 40 governments spanning Europe and the Pacific. A growing number of businesses, including major corporations like Google, BMW, Volvo, and Renault, have also voiced their opposition. Furthermore, several major UK banks have indicated they will not provide financial support for the industry, and other international investors are also withdrawing their investments. Indigenous communities in the Pacific have also strongly voiced their objections, emphasizing the potential for deep-sea mining to severely threaten the ocean ecosystems upon which their cultures, livelihoods, and well-being depend.
Deep-sea mining is a relatively nascent industry, with only limited exploratory tests having been conducted to date. The process involves utilizing heavy machinery to extract valuable metals and minerals from the ocean floor, located thousands of meters beneath the surface. Metals such as cobalt and nickel are of particular interest to companies due to their crucial role in the production of modern electronics and computer components. The extracted minerals are then transported to the surface using equipment that can weigh more than a blue whale.
The environmental consequences of deep-sea mining are considered to be extremely severe, comparable to destructive land-based mining practices. The nodules containing these valuable resources are often home to unique and potentially irreplaceable ecosystems. The mining of these deposits would inevitably lead to the destruction of biodiversity and habitats that are not yet fully understood. Additionally, the operation of underwater mining equipment can generate significant underwater noise pollution, which can severely disrupt the communication and navigation of marine mammals like dolphins and whales, who rely heavily on echolocation.
The legal challenge brought by the environmental organization underscores the growing international concern regarding the potential ecological risks associated with deep-sea mining. The outcome of this judicial review could have significant implications for the future of deep-sea exploration and the government’s policy stance on this controversial industry. The case highlights the ongoing tension between the potential economic benefits of accessing deep-sea resources and the imperative to protect vulnerable marine environments.
