In 2022, we conducted a total of 98 supplier reviews – 83 of which were on-site reviews (social audits ) and 15 mobile surveys. 40 direct and 58 indirect suppliers were involved in the checks.

For the on-site reviews, we let the supplier know the approximate time of our visit in advance (“semi-announced audit ”). This is necessary to make sure that relevant contacts in key functions are present for the audit. The mobile surveys give our suppliers’ employees the opportunity to provide anonymous information about the social and ecological situation at their company. The surveys are primarily used to gain an initial impression of the local working conditions in order to then initiate further measures as needed, such as specific on-site reviews (social audits).
