Our whistleblowing system for Human Rights and environmental violations

Our electronic whistleblowing system is the central possibility for anonymous or named reporting of potential human rights violations or environmental violations at HOCHBAHN, our subsidiaries or our suppliers. 

HOCHBAHN protects you as a whistleblower and offers you this platform for communication, which is secured with the help of the most up-to-date technologies. You can also set up an anonymous mailbox for yourself here and thus actively participate during the investigation.

The whistleblowing system can be accessed online via the following link and is free of charge for whistleblowers to use

Further information on the complaints procedure is described in the Rules of Procedure.
