BMW, Volvo, Google and Samsung call for ban on deep-sea mining

The companies are the first global businesses to support a World Wildlife Fund (WWF) call for a moratorium on mining the seabed, which could deal a major blow to firms planning to mine the deep ocean this decade.

The signatories have also said they will not finance any deep sea mining companies.

“Before any potential deep seabed mining occurs, it needs to be clearly demonstrated that such activities can be managed in a way that ensures the effective protection of the marine environment,” they said in the statement.

“All alternatives to deep sea minerals must be explored as a matter of urgency, with a focus on reducing demand for primary metals, transitioning to a resource-efficient, closed-loop materials economy, and developing responsible terrestrial mining practices,” the companies noted.

Mining the ocean floor has been promoted as an alternative to land-based mining, as demand for minerals needed for a green energy transition, such as cobalt and nickel, are set to exceed current production rates by 2030.

Yet regulations to support the emerging activity have yet to be agreed upon by the International Seabed Authority (ISA). The UN-backed body of 167 countries has already issued exploration contracts to 21 companies, but they cannot begin mining until regulation is passed.

An international team of researchers published in 2018 a set of criteria to help the ISA protect biodiversity from deep-sea mining activities while it prepares global rules.

According to the US Geological Survey, the deep-sea accounts for more than half the world’s surface and contains minerals in concentrations several times higher than those found in all land reserves combined.

Targeting nodules
The main target of companies planning to mine underwater are polymetallic nodules. These small rocks, which lie in a shallow layer of mud on the seafloor, are rich in cobalt, nickel, copper, manganese and rare earths.

Scientists and explorers have also identified cobalt-rich crusts, located shallower than nodules and sulphates.

Recent reports, including one commissioned by the High Level Panel for a Sustainable Ocean Economy (Ocean Panel), have called for further research to fill gaps in knowledge before any seabed mining is allowed. They have also argued for the need to set protected zones across all ocean regions under the ISA’s jurisdiction.

The European Parliament has also called for a ban on seabed mining until the environmental impacts and risks of disturbing unique deep-sea ecosystems are understood.
