The European Automotive Working Group on Supply Chain Sustainability has developed a set of guidelines for their suppliers to enhance sustainability performance in the supply chain. The guidelines cover four main areas: business ethics, working conditions, human rights, and environmental leadership. The guidelines are based on fundamental principles of social and environmental responsibility and are compliant with local law, consistent with international expectations, and supported by the sponsoring auto manufacturers. The automotive industry supply chain is complex, and the group believes in the benefits of a common approach and message. The guidelines expect suppliers to uphold these standards and cascade them down their supply chain. Individual manufacturers may have their own standards, codes, and policies that supersede these guidelines.
