Ombudsperson - Confidential helpline

Telefónica Germany GmbH & Co. OHG has appointed an independent lawyer as Ombudsperson for the fight against corruption and for the prevention and mitigation of human rights and environmental risks and violations as part of its whistleblowing procedure.

Dr. Rainer Buchert, Frankfurt am Main, accepts confidential information regarding corruption and other criminal activities, such as fraud and breach of trust, and antitrust violations, as well as (imminent) violations of human rights and environmental obligations under the German Supply Chain Due Diligence Act (LkSG), within the Telefónica Deutschland Group and its direct and indirect suppliers. The LkSG regulates the human rights and environmental obligations that large German companies must fulfil in their own business operations as well as in their supply chains. Our whistleblowing procedure corresponds to the complaint procedure of the LkSG and thus implements one of the due diligence obligations that companies must establish in order to fulfil their responsibility to respect human rights.
