Energy Management Systems Scheme

The scheme is based on ISO 50001:2011 - Energy management systems - Requirements with guidance for use. Compliance with this standard helps organisations improve their energy performance, increase energy efficiency and reduce climate change impacts. ISO 50001 is aligned with other management systems standards such as ISO 9001 and ISO 14001, allowing organisations to easily integrate systems.

Applicant CABs will need to comply with ISO 50003:2014 - Energy management systems - Requirements for bodies providing audit and certification of energy management systems.

As a management systems scheme, applicants also need to comply with ISO/IEC 17021-1:2015 Conformity Assessment – Requirements for bodies providing audit and certification of management systems.  Part 1: Requirements.
