In 2019, Resource Matters published a report alleging that companies producing technology that requires cobalt (such as cell phones, cars, or others with rechargeable batteries) are unable to avoid the potential corruption in the DRC. The report links Glencore, the world's largest provider of cobalt, to risky payments to companies sanctioned for corruption and recommends stronger due diligence and audits of Glencore's purchasing and payments.

Business & Human Rights Resource Centre invited Glencore and four companies evaluated as the worst performers to respond. Glencore and NEVS responded. CATL, Ecopro and GEMs did not respond.
