"In fiscal 2018, Sony worked with refineries and supported industry initiatives to encourage cobalt refineries in Sony’s supply chain to further address human rights risks. Specifically, cobalt refineries that were identified in the supply chain were asked to join the audit program for cobalt refineries launched by RMI. Sony also donated funds to the Responsible Business Alliance Foundation, which covers the cost for refineries to undergo assessments and facilitates RMI’s audit program."
