In addition to our online Sustainability Report, we publish various other sustainability-related documents. These include relevant information and indicators in accordance with the requirements of the U.S. SASB (Sustainability Accounting Standards Board). We also documented the relevant disclosures in accordance with the standard of the TCFD (Task Force on Climate-related Financial Disclosures) in a separate index. We monitor the effectiveness of our material topics with key performance indicators (KPIs) in the Evaluation sections of the respective chapters in our Sustainability Report. With our Interactive KPI Tool you can analyze and graph a variety of key figures. We also disclose additional ESG KPIs in a separate overview (ESG KPI Overview).
