Sony least transparent about ethical material sourcing, Apple is most, according to report

As part of annual reports to the U.S. Securities and Exchange Commission on ethical material sourcing, Apple reported that 100% of its sourced mineral refineries had no evidence of supporting armed conflict in 2018. Sony, on the other hand, did not reveal how many of its suppliers completed surveys of its refineries and could not confirm the status or even location of many of its sourced refineries.
