The 2018 version of ISO 50001 was published on 21 August 2018. With this release, ISO 50001:2011 will be withdrawn. The transition deadline is confirmed by the International Accreditation Forum (IAF) to be three years from the publication date. To keep a certificate valid after this deadline, companies need to make sure their certificate is transitioned during the 3-year period. Certification bodies, such as DNV GL, are required to stop performing audits according to ISO 50001:2011 18 months after publication date. This means that certified companies need to plan accordingly.
We recommend to start the preparations for the transition already now, to ensure a smooth process.
ISO 50001 provides requirements for a systematic, data-driven and facts-based process, focused on continually improving energy performance. The key explicit intended outcomes from implementing the standard is to achieve continual improvement in energy performance and the energy management system.
Main changes in ISO 50001:2018
The main objectives and scope of the revision as stated in the design specifications from the ISO Working Group (TC242) were:
- Adopt the ISO High Level Structure (HLS), common for all ISO standards, to ensure compatibility with other ISO Management System standards
- Ensure that core concepts of 2011-edition are retained, such as:
- continual improvement of energy performance;
- focus throughout the standard to improve energy efficiency, energy consumption and energy use;
- include the necessary energy specific topics related to energy performance such as energy data, monitoring, measurement, analysis and evaluation.
Since ISO 50001:2018 applies the HLS, it follows the same structure as other widely applied ISO standards, such as ISO 9001 and ISO 14001. This simplifies integration with other management systems.
Users familiar with ISO 50001:2011 will recognize that most of the requirements of the ISO 50001:2011 are continued in ISO 50001:2018. This is particularly the case for the more energy specific elements and requirements, which is not a surprise with the stated objective for the revision. There are some new and revised requirements, most of them due changes induced by the HLS. However, there are also some other energy specific changes, mainly to foster clarifications to the requirements based on experience from use of the 2011-edition. Learn more about the changes here.
