More than ever before, global companies are forced to deal with critical issues in the supply chain such as forced labor and conflict minerals. For example, the average smartphone contains more than 40 different minerals including four "conflict minerals" (tin, tantalum, tungsten, gold). Cobalt, a critical component in lithium-ion batteries, is mostly produced in the Democratic Republic of Congo (DRC), which has struggled with periodic violence and human rights abuses. So, how can companies (especially manufacturers) guarantee responsible sourcing, gain visibility into the supply chain, effectively manage risks and ensure sustainability? How can they keep up with emerging regulations as well as stakeholder expectations? As part of our "Sustainable Business" series, we traveled to Washington D.C. and the DRC to speak with Jamie Wallisch of Assent on the key trends, challenges, and opportunities.
