Brazil wants 10-year pause on deep-sea mining as UN agency under pressure to draft regulations

Brazil has sought a 10-year precautionary pause on deep-sea mining in international waters just days after companies and countries were allowed to start applying for provisional licenses.

The call came during a two-week conference held by the International Seabed Authority, a regulatory UN agency based in Jamaica that failed to approve a set of rules and regulations to govern deep sea mining by a July 9 deadline.

The agency has not issued any provisional licenses, nor has it received any applications, although the government of Nauru is expected to apply soon for a license via the Canadian-based Metals Co.

The government of the tiny Pacific island on Friday said it wants to diversify its "limited economic base," but promised it would not sponsor an application during the UN conference, which ends July 21.

Nauru noted that its 'good-faith decision' does not mean officials are withdrawing their plan to pursue deep sea mining.

"We're no longer in a what if' scenario, but what now?" said Margo Deiye, Nauru's permanent representative to the International Seabed Authority.

A growing number of countries and companies, including BMW and Volvo, support a moratorium on deep-sea mining, warning that extracting precious metals from the deep sea that are used in electric car batteries and other green technology could cause environmental damage.

Brazil's representative to the International Seabed Authority, Elza Moreira Marcelino de Castro, said the country supports a precautionary pause for at least a decade.

"Priority must be given to the protection of the international seabed until conclusive and comprehensive studies are available," she said.

Scientists have warned that deep sea mining could kick up dust storms and cause light and noise pollution, noting that minerals that grow at such depths take millions of years to form.

Companies, however, have said that deep-sea mining is cheaper and has less of an impact than land mining, while some countries have said it would allow them to grow and diversify their economy.

On Friday, several council members insisted on more scientific studies before any licenses are awarded.

"Exploitation must not commence until it can be guaranteed that there will be no loss to biodiversity," said Siddharth Shekhar Yadav, Vanuatu's representative.

The UN agency has issued more than 30 exploration licenses, with most of the activity focused in the Clarion-Clipperton Fracture Zone, which covers 4.5 million square km between Hawaii and Mexico. Exploration is occurring at depths ranging from 13,000 to 19,000 feet.

The UN agency's 36-member council is working on a proposed framework that would regulate potential deep sea mining, but it's unclear when it would be ready.

"Exploitation in the area should not be carried out in the absence of rules, regulations and procedures," Gina Guillen, Costa Rica's representative, said in a statement that represented the stance of more than a dozen countries.

Australia's representative on Friday said it was clear draft regulations would not be ready before the conference ends nor by the next meeting scheduled for October and November.
