The sustainability topics are the result of the regular validation of the materiality assessment, the implementation and development of the ProSiebenSat.1 sustainability strategy, and the continuous dialog with internal and external stakeholder groups. Information on the implementation and results of ProSiebenSat.1 Group's materiality assessment can be found in the "Double Materiality Assessment" section of the Sustainability Report. Our most important stakeholder groups and methods of engagement are described in the chapter "Interests and Views of Stakeholders".
