In the event of questions or comments on compliance or sustainability issues you are requested to contact the central Responsibility Management.


We have also set up a help desk. The help desk is available to provide assistance to all employees and to our business partners as the central point of contact for all compliance and sustainability related questions and comments, and for any notification of breaches.


In addition, Dr. Carsten Thiel von Herff, LL.M., can be contacted as independent legal counsel. All employees and business partners may seek out the independent legal counsel in confidence and anonymously in the event of suspicion of a violation of the law and/or a breach of our internal rules of conduct.​​​​​​​
