ISO 50001

ISO 50001 is an international standard developed by the International Organisation for Standardisation (ISO) which provides organisations with the requirements for energy management systems. ISO estimates that the standard could influence up to 60% of the world’s energy use.

ISO 50001:2018 is published

Published on 21 August 2018, ISO 50001:2018 now reflects Annex SL, the high-level structure for all new and revised ISO standards and helps bring energy management and continual improvement into the core of an organisation. 

The new structure has improved its compatibility with ISO 14001, the environmental management system (EMS) standard that was revised in 2015, enabling easily integration with this standard and other new and revised ISO standards.

  • Minimising risk - reduces risk and increases energy security.
