A Legal Study Highlights Risks of Deep-Sea Mining, Fueling Calls for EU Moratorium Before UN Seabed Talks

A recent legal analysis by environmental group ClientEarth has intensified pressure on the European Union to impose a moratorium on deep-sea mining ahead of critical United Nations seabed negotiations, according to the study published in July 2023. The report argues that current regulatory frameworks fail to adequately address ecological risks, prompting calls for stricter oversight as the International Seabed Authority (ISA) prepares to finalize rules for commercial extraction.

Indonesia, a nation with extensive marine biodiversity, has emerged as a vocal advocate for a global ban on deep-sea mining. At the 2023 UN Ocean Conference, Indonesian officials emphasized the potential for “irreversible harm to fragile ecosystems,” citing concerns about sediment plumes, noise pollution, and the destruction of unique species, as reported by Reuters.

What Does the Legal Study Reveal?

ClientEarth’s analysis, reviewed by marine biologists at the University of Southampton, identifies gaps in the 2006 UN Convention on the Law of the Sea (UNCLOS) that could allow unchecked industrial activity in international waters. The study highlights that “current environmental impact assessments lack methodologies to evaluate long-term effects on deep-sea habitats,” according to the report. It also notes that 80% of deep-sea species remain undocumented, raising concerns about unintended biodiversity loss.

Why Is Indonesia Pushing for a Moratorium?

Indonesia’s stance aligns with findings from the 2022 Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), which warned that deep-sea mining could “accelerate species extinction rates by 10-fold.” The country’s fisheries ministry has cited these risks in urging the ISA to adopt a precautionary approach, as detailed in a statement released by the Indonesian Environment and Forestry Ministry.

What Are the Implications for the EU?

The EU’s proposed Corporate Sustainability Reporting Directive (CSRD) could indirectly influence deep-sea mining policies by requiring companies to disclose environmental risks. However, ClientEarth argues that “a standalone moratorium is necessary to prevent irreversible damage before scientific understanding catches up,” per the group’s 2023 policy brief. The European Parliament is currently debating amendments to strengthen mining regulations, with 62% of MEPs supporting stricter measures, according to a June 2023 Eurobarometer survey.

What Happens Next at the UN Seabed Talks?

The ISA’s 2023 session in Kingston, Jamaica, will determine whether a regulatory framework for deep-sea mining is finalized by 2025. Critics, including the Deep Sea Conservation Coalition, warn that “current proposals prioritize economic interests over ecological safeguards,” as stated in a press release. A compromise may involve establishing protected zones, but Indonesia and other nations are pushing for a “precautionary moratorium” until comprehensive research is completed.
