Blockchains are databases of information shared over computer networks. Any member can add a record. However, it is extremely difficult to change this later. Moreover, the network constantly checks the information is identical on all computers. Volvo has started blocking illegal cobalt in its EV batteries by using this technology.
How Volvo is Blocking Illegal Cobalt through Its Main Suppliers
Volvo sources its electric vehicle batteries from CATL, China and LG Chem of South Korea. It announced on November 6, 2019 they would work together to ensure Volvo batteries contain ethical cobalt.
This is the first blockchain attempt at blocking illegal cobalt out the supply chain according the Elektrek. This move is simultaneous with news of Volvo’s XC40 Recharge electric SUV. Moreover, the company will start selling its Polestar all-electric and plug-in EV’s in 2020. The agreement with LG Chem and CATL secures battery supply to Volvo and Polestar for ten years.
Could This Be the End of Cobalt Child Labor?
We hope at least the beginning the end of these inhumane practices on some Democratic Republic of Congo cobalt mines. Unfortunately, this is unlikely to be the case because of apparent lack of global cooperation. Martina Buchhauser, head of procurement at Volvo Cars drew a line in the sand when he said:
“We have always been committed to an ethical supply chain for our raw materials. With blockchain technology, we can take the next step toward ensuring full traceability of our supply chain and minimizing any related risks, in close collaboration with our suppliers.”
We call on all electric car makers to follow Volvo’s lead on this. Amnesty International has been asking for action for years. We just need to imagine our own children chopping rock in a mine tunnel. Then blocking illegal cobalt should fall into place.
