Our Whistleblower System

Complying with statutory regulations and internal rules has top priority at MAN Energy Solutions. The success of our company is based on Integrity and Compliance. To meet this standard, it is important to learn about potential employee misconduct and to put a stop to it. Therefore, we entrusted the Central Investigation Office of Volkswagen AG to operate an independent, impartial and confidential Whistleblower System on our behalf. The qualified and experienced colleagues at the central Investigation Office examine every report thoroughly and follow it up systematically.

A key pillar of our Whistleblower System is the principle of procedural fairness. It also guarantees the greatest possible protection for whistleblowers, persons implicated and employees contributing to the investigation of reported misconduct. 

This also includes offering opportunities for anonymous reporting and communication. We assure not to perform any steps in order to identify anonymous whistleblowers, who do not misuse our Whistleblower System. Retaliation of whistleblowers and all persons who contribute to investigations at MAN Energy Solutions will not be tolerated. Persons implicated are presumed innocent until the violation is proven. Investigations will be conducted with the utmost confidentiality. The information will be processed in a fair, fast and protected process.
