Major electronics brands, including Apple, Samsung and Sony, are failing to do basic checks to ensure that cobalt mined by child labourers has not been used in their products, said Amnesty International and Afrewatch in a report published today. The report, This is what we die for: Human rights abuses in the Democratic Republic of the Congo power the global trade in cobalt, traces the sale of cobalt, used in lithium-ion batteries, from mines where children as young as seven and adults work in perilous conditions...The report documents how traders buy cobalt from areas where child labour is rife and sell it to Congo Dongfang Mining (CDM), a wholly-owned subsidiary of Chinese mineral giant Zhejiang Huayou Cobalt Ltd (Huayou Cobalt). Amnesty International’s investigation uses investor documents to show how Huayou Cobalt and its subsidiary CDM process the cobalt before selling it to three battery component manufacturers in China and South Korea. In turn, they sell to battery makers who claim to supply technology and car companies, including Apple, Microsoft, Samsung, Sony, Daimler and Volkswagen...Amnesty International contacted 16 multinationals who were listed as customers of the battery manufacturers listed as sourcing processed ore from Huayou Cobalt. One company admitted the connection, while four were unable to say for certain whether they were buying cobalt from the DRC or Huayou Cobalt. Six said they were investigating the claims. Five denied sourcing cobalt from via Huayou Cobalt, though they are listed as customers in the company documents of battery manufacturers. Two multinationals denied sourcing cobalt from DRC. Crucially, none provided enough details to independently verify where the cobalt in their products came from...Amnesty International and Afrewatch are calling on multinational companies who use lithium-ion batteries in their products to conduct human rights due diligence, investigate whether the cobalt is extracted under hazardous conditions or with child labour, and be more transparent about their suppliers.
