Volvo Cars will become the first carmaker to implement global traceability of cobalt used in its batteries by applying blockchain technology. The announcement follows the reveal last month of the company’s first fully electric car, the XC40 Recharge.
Traceability of raw materials used in the production of lithium-ion batteries, such as cobalt, is one of the main sustainability challenges faced by carmakers. Volvo Cars is committed to full traceability, ensuring that customers have peace of mind and can drive electrified Volvos knowing the material for the batteries has been sourced responsibly.
Blockchain technology, which establishes a transparent and reliable shared data network, significantly boosts transparency of the raw material supply chain as the information about the material’s origin cannot be changed undetected.
Volvo Cars has now reached an agreement with its two global battery suppliers, CATL of China and LG Chem of South Korea, and leading global blockchain technology firms to implement traceability of cobalt starting this year.
“We have always been committed to an ethical supply chain for our raw materials,” said Martina Buchhauser, head of procurement at Volvo Cars. “With blockchain technology, we can take the next step towards ensuring full traceability of our supply chain and minimizing any related risks, in close collaboration with our suppliers.”
A blockchain is a digital ledger containing a list of records linked to each other via cryptography. Within supply chains, the technology creates records of transactions which cannot be changed, while also enforcing a common set of rules for what data can be recorded.
Volvo Cars last month launched the XC40 Recharge, the first of an upcoming family of fully electric cars under the Recharge banner. By 2025, it expects half of its global sales to consist of fully electric cars, with the rest hybrids.
Last month, Volvo Cars also launched an ambitious climate plan, which includes a radical reduction of carbon emissions by 40 percent per vehicle by 2025, as well as a continued commitment to ethical business across its entire operations and supply chain.
CATL and LG Chem are renowned battery manufacturers, both with long and successful track records supplying lithium-ion batteries to the global automotive industry. They fulfill Volvo Cars’ strict sourcing guidelines in terms of technology leadership, responsible supply chains, reduction of carbon emissions and competitive cost models.
According to Greg Maruszewski, Managing Director of Volvo Car South Africa, cobalt has long been a conundrum for vehicle manufacturers. “thanks to blockchain traceability, we will know that the cobalt has been sourced responsibly”. We are the first and only vehicle manufacturer that can make this statement. Accordingly, South African motorists who buy a Volvo in our XC90 T8 range can do so with pride – with the guaranteed knowledge that only ethical mining practices have taken place in the cobalt supply chain,” he explains.
