Environmental management systems

The certification of our environmental management system requires regular assessment of certified plants of VERBUND by external auditors.

VERBUND has implemented environmental management systems in accordance with ISO 14001 at all power plants and grid facilities, as well as the large administrative sites. Our thermal power plants in Mellach are additionally validated according to the EMAS regulation. For these plants, a separate environmental statement is published annually on this website. New plants are integrated into the environmental management system as quickly as possible after commissioning and included in the scope of  the certificate during the subsequent audit.

If you have any questions concerning the scopes of our environmental management systems, please write an email to our sustainability team.

Certificates of management systems in other areas like CRS, quality, energy or health & safety are also listed in the following table.
