Automakers back moratorium on deep seabed mining

- By Frank Jordans

BERLIN >> Automakers BMW and Volvo announced Wednesday that they support a moratorium on deep seabed mining for minerals used in electric vehicle batteries and other products.

In a statement also backed by Samsung’s EV battery unit and tech giant Google, the companies cited the importance of protecting fragile ocean ecosystems that are already under threat from overfishin­g, pollution, noise and man-made climate change.

While deep seabed mining is still in its infancy, several prospectin­g firms are seeking rights to extract potentiall­y lucrative deposits from the depths of the ocean, particular­ly the metallic nodules that build up around hydrotherm­al vents.

“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,” the four companies said in their 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,” they said.

The companies said they were committed “not to source minerals from the deep seabed; to exclude such minerals from our supply chains; and not to finance deep seabed mining activities.”

The call was supported by the environmen­tal group World Wildlife Fund, which has campaigned against deep seabed mining.

“We need to take pressures off the ocean, not add additional pressures to it in order to guarantee that the ocean can provide services to humanity, such as climate regulation, food and medicines, into the future,” said Jessica Battle, who heads the WWF campaign against deep seabed mining.

While minerals mined from the ocean floor can be used for a variety of goods, they are of particular interest to high-tech industries that rely on precious and rare metals.

“At least one of the leading nodule mining contractor­s, DeepGreen, cites generating metals for EV batteries as their major motivation for large-scale mining,” said Craig Smith, a professor of oceanograp­hy at the University of Hawaii at Manoa.

Stefan Bratzel, director of the Center of Automotive Management in Germany, said the announceme­nt by BMW and Volvo was significan­t for other car manufactur­ers. “It underlines the importance of ecological considerat­ions in a comprehens­ive well-to-wheel perspectiv­e,” he said, adding that other automakers “will now at least hesitate to use minerals mined from the ocean in their electric vehicle batteries.”

Global Sea Mineral Resources, a company exploring deep seabed mining, said it didn’t support the moratorium but claimed environmen­tal surveys are already required by the Internatio­nal Seabed Authority, which regulates the industry.
