ISO 50001 is an international energy management system standard that gives organisations of any size a tool to systematically optimise energy performance and promote more efficient energy management.

First published in 2011, a new edition of the standard was released in August 2018. Read more about ISO 50001:2018 requirements and transition timelines below.

ISO 50001:2018 Energy management systems – Requirements with guidance for use, has been aligned with the structure of ISO management system standards such as ISO 9001 Quality management and ISO 14001 Environmental management. The common structure is designed to ease the integration into management systems that have already been established in an organization. Furthermore, the updated version includes a stronger emphasis on the responsibilities of top management, to instil a cultural change in the organisation.
