The Sustainability Report essentially consists of the Sustainability Magazine and GRI Report and has been prepared in accordance with the GRI Standards: core option. In addition, the Sustainability 2019 Report serves as the Communication on Progress (COP), which all companies participating in the UN Global Compact are obliged to publish annually. When defining the report content, we observed the principles of “stakeholder inclusiveness,” “sustainability context”, “materiality”, and “completeness”. The sections “Our Responsibility” and “GRI Report” of the Sustainability Report were subjected to an independent audit with limited assurance by EY (Ernst & Young) Wirtschaftsprüfungsgesellschaft. Such audits are based on the relevant ISAE 3000 (Revised) standard.
