Volvo Cars will use blockchain technology to track the origin of cobalt that is used in cars\u2019 batteries. More than half of the world\u2019s cobalt supply comes from the Democratic Republic of Congo. In this war-inflicted area, extensive child labor is used in order to mine cobalt.\r\n\r\nVolvo Cars said that it would make the cobalt used in its batteries globally traceable using blockchain technology, Reuters reported. Volvo signed an agreement with its two battery suppliers, China\u2019s CATL and South Korea\u2019s LG Chem, to carry out the project.\r\n\r\nThe companies behind manufacturing electric cars had been facing scrutiny from all around the world as they failed to keep track of the cobalt that is used in the cars\u2019 batteries. Cobalt is used to make lithium-ion batteries used in electric cars. But more than half of the supply comes from the war-hit Democratic Republic of Congo.\r\nVolvo is first to implement global traceability of cobalt\r\nIn this African country, extensive child labor is used to mine this blue metallic element. Any company using cobalt can encourage authorities in the country to violate basic human rights. Nearly 20% of the total mining of cobalt is done by children using their bare hands.\r\nVolvo will ensure full traceability of raw materials.\r\nVolvo Cars\u2019 head of procurement, Martina Buchhauser, said that with blockchain technology, they could take the next step towards ensuring full traceability of their supply chain and minimizing any related risks. The Responsible Sourcing Blockchain Network (RSBN), in collaboration with IBM and RCS Global, will roll out the technology in LG Chem\u2019s supply chain.
