Client note: In support of the ISO London Declaration on Climate Change, ISO passed a resolution last year that has resulted in two new statements of text being added to a number of existing management systems standards (MSS), and will be included in all new standards under development/revision, to address the need to consider the effect of Climate Change on the ability to achieve the intended results of the management system.
If you previously bought one of the below quality management standards, you will be entitled to receive an updated amendment with the 2024 London Declaration version of the standard:
- BS EN ISO 29001:2020
- BS EN ISO 41001:2018
- BS EN ISO 22301:2019
- BS EN ISO 19443:2022
- BS EN ISO 37101:2022
- BS EN ISO 22000:2018
- BS EN ISO 34101-1:2020
- BS EN ISO 15378:2017
- BS EN ISO 9001:2015
- BS EN ISO 14001:2015
- BS EN ISO 45001:2023
- BS EN ISO/IEC 27001:2023
- BS EN ISO 50001:2018
If you’re eligible for the revised 2024 London Declaration version, we will be in touch as soon as possible. For further information and any questions you may have, please contact cservices@bsigroup.com.

What is this ISO 50001 - Energy management systems about?
ISO 50001 - Energy management systems helps organizations use energy more efficiently and integrate better energy management into business strategy. It does this by outlining how to implement and maintain an energy management system (EnMS) that continually improves the organization’s energy performance and saves money.
Who is ISO 50001 - Energy management systems for?
ISO 50001 - Energy management systems for use by any organization, regardless of its type, size, complexity, geographical location, organizational culture, or the products and services it provides. Specifically, the standard will be used by:
- Any organization wanting to improve energy management to reduce costs and carbon emissions
- Any organization wishing to implement an energy management system
- Those who want to develop a deeper understanding of internationally recognized best practices for energy management
- Users of ISO 14001 who would like to develop their energy management systems
Why should you use ISO 50001 - Energy management systems?
Implementing an energy management system provides a systematic approach necessary to continually improve energy performance. Once in place, an energy management system enables an organization to set and achieve objectives and energy targets, take action to improve its energy performance and benefit from efficiency and costs savings as a result.
ISO 50001 - Energy management systems will help organizations to reduce energy costs, grow more sustainably, become more resilient and comply with legislation. The standard:
- Applies to activities affecting energy performance that are managed and controlled by the organization
- Applies irrespective of the quantity, use, or types of energy consumed
- Requires demonstration of continual energy performance improvement but does not define levels of energy performance improvement to be achieved
- Can be used independently, or be aligned or integrated with other management systems
What’s changed since the last update?
ISO 50001:2018 - Energy management systems incorporates ISO’s new high-level structure (HLS) of terms, definitions, and headings, thus bringing the 2018 standard into line with the other key management systems standards. It makes this version compatible and easier to integrate with ISO 9001 and ISO 14001, which are now also in the ‘HLS’ format.
Other key changes and benefits of ISO 50001 - Energy management systems include:
- A stronger emphasis on the responsibility of leadership
- Clarification of key concepts related to energy performance
- Improved sections on data collection and normalization
- Additional minor revisions reflecting seven years of using the standard in the real world
