A global inquiry led by a group of investors, the Church of England (CoE) Pensions Board and the Swedish Council of Ethics of the AP Funds, was launched after the collapse of a Vale dam in January 2019.
The major investors, who manage assets worth a combined USD $13.5 trillion, have made a number of interventions including a call for a new international standard for tailings dams, and called upon 727 companies from extractive industries to disclose information about their tailings dams to form an independent global database.
