Energy Management Systems Scheme

Energy Management Systems Scheme

The scheme is based on ISO 50001:2018 - 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 - Energy management systems - Requirements for bodies providing audit and certification of energy management systems.  CABs already accredited in this scheme are required to apply to JAS-ANZ for transition from ISO 50003:2014 to ISO 50003:2021 before 30 November 2023. Certification bodies seeking initial accreditation for EnMS are required to apply for accreditation to ISO 50003:2021.

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


Effective implementation of ISO 50001:2018 provides a systematic approach to improvement of energy performance that can transform the way organisations manage energy. By integrating energy management into business practice, organisations can establish a process for continual improvement of energy performance.  By improving performance and associated energy costs, organisations can be more competitive. In addition, implementation can lead to organisations meeting overall climate change mitigation goals by reducing their energy-related greenhouse gas emissions.
