The White House is weighing an executive order that would fast-track permitting for deep-sea mining in international waters and let mining companies bypass a United Nations-backed review process, according to two sources with direct knowledge of the deliberations.

If signed, the order would mark U.S. President Donald Trump’s latest attempt to tap international deposits of nickel, copper and other critical minerals used widely across the economy after recent efforts in Greenland and Ukraine. Trump earlier this month also invoked emergency powers to boost domestic minerals production.

The International Seabed Authority - created by the United Nations Convention on the Law of the Sea, which the U.S. has not ratified - has for years been considering standards for deep-sea mining in international waters, although it has yet to formalize them due to unresolved differences over acceptable levels of dust, noise and other factors from the practice.

Trump’s deep-sea mining order is likely to stipulate that the U.S. aims to exercise its rights to extract critical minerals on the ocean’s floor and let miners bypass the ISA and seek permitting through the U.S. Department of Commerce’s National Oceanic and Atmospheric Administration’s mining code. The plans are under discussion and could change before Trump signs the order, the sources said.

    Carbon Brief published a great article on this subject: Q&A: What does deep-sea mining mean for climate change and biodiversity loss? Some takeaways on its impacts:

    • A 2020 study stated that “scientific misconceptions are likely leading to miscalculations of the environmental impacts of deep-seabed mining”. It added that the disturbance from a single mining operation “could easily be” up to four times larger than its direct mining footprint, affecting up to 32,000 square kilometres over 20 years.
    • The potential cost of restoring damage to deep-sea ecosystems could be “astronomical”, according to a report by Planet Tracker, a not-for-profit thinktank.
    • A 2022 UN Environment Programme Finance Initiative (UNEPFI) briefing paper saw “no foreseeable way” in which the financing of deep-sea mining could be consistent with a sustainable blue economy. It called on investors to instead “focus efforts” on reducing “the environmental footprint of terrestrial mining” and “support the transition toward a circular economy” to make current mineral demand “obsolete”.
    • A 2023 study found that deep-sea mining “is unlikely to resolve the sustainability challenges in the conventional mining sector” and any environmental impacts avoided on land “would be at the expense of economic benefits in mining-reliant” developing countries.

    Deep-sea mining can also harm marine organisms that are crucial for climate regulation – those that store carbon in the seabed or produce oxygen in the deep ocean.

    • A 2024 study found that polymetallic nodules may be responsible for producing oxygen at the seafloor in the CCZ. The authors said that this oxygen production could be critical for sustaining life at the seafloor.
    • A 2025 Nature study provided a rare insight into some of the lasting impacts that mining can cause. It focused on a 1979 mining experiment in the Clarion-Clipperton Zone. During the 1979 test, a mining machine drove grooves into the seafloor. These furrows, which were almost one metre deep and up to three metres wide, looked much the same after 44 years. These impacts are consistent with findings in other surveys of mined test sites.

    Seafloor mining vehicles emit toxic plumes of sediments that can impact marine life in the midwaters, from reducing their ability to communicate and causing physiological stress, to forcing species to migrate. Species that could be impacted include sharks, dolphins, whales, squid, fish, shrimp, copepods and jellyfish.
