Environmental groups propose tailings dam safety standards

Mining companies should be required to buy private insurance for tailings dams and their board of directors should be held legally responsible for any disasters, a coalition of 140 environmental groups said in a report published on Tuesday.

The recommendations, which differ from standards to be published soon from a group that includes miners and investors, come as public scrutiny over tailings dams has intensified after the deadly 2019 collapse of a Brazil dam owned by Vale.

Earthworks and MiningWatch Canada, two prominent environmental nonprofits, co-wrote the report that includes 16 recommendations they hope will be adopted by regulators across the world and used by bankers as they consider whether to lend to miners.
