"For those cases where there are indications of risks, the second step takes a look at the entire supply chain. In so doing, we go beyond the direct suppliers to create transparency, and even go right down to the mine where necessary. Our interdisciplinary teams undertake "supply chain walks" to carry out on-site inspections and audits, while communication and training measures for suppliers are also part of HRRS. Furthermore, we also talk to the local people, the so called right holders. Their perspectives are an important aspect in the implementation of the Human Rights Respect System. Starting point of the Supply Chain Walks is the Tier 1 supplier and then the path goes along the critical points in the supply chain, if necessary to the mine. These onsite checks are carried out by interdisciplinary teams. They consist of representatives of the 700 quality engineers and experts in sustainability, human rights and compliance."
