A new report has warned that a scheme set up to ensure mining in the Democratic Republic of Congo does not fuel conflict is being abused to launder tainted minerals. Global Witness says companies – including Apple, Tesla, and Intel – are relying on the due diligence scheme to source minerals that are widely used in electronic equipment such as mobile phones, computers, and automotive and aeronautical systems. Those behind the initiative have denied the allegations. The scheme was launched to try to prevent these so-called “blood minerals” from reaching the international market. But Global Witness says it has uncovered compelling evidence that the International Tin Supply Chain Initiative is failing.
