ISO 50001 REVISION UPDATE MOVING FORWARD WITH THE RELEASE OF THE INTERNATIONAL STANDARD

The latest version of the energy management system (EnMS) standard, ISO 50001:2018, was published on 21 August, 2018. This revision marks the second edition of the standard. ISO 50001 has become increasingly relevant since its release in 2011. Nearly 20,216 organisations were certified to the standard by the end of 2016. A global survey shows that ISO 50001 certifications increased by 69% during 2016. According to ISO, available evidence shows that organisations adopting the ISO 50001 standard benefit from initial energy improvements of 10% or more and achieve net cost savings, mostly through low cost or no cost changes to operations. The standard is business friendly, globally relevant and transformational. It aims to enable organisations to establish systems and processes needed to continually improve energy performance – including energy efficiency, energy use, and energy consumption – by providing the requirements for a systematic, data-driven and facts-based process. Energy performance indicators (EnPIs) and energy baselines (EnBs), two interrelated elements addressed in ISO 50001, enable organizations to demonstrate energy performance improvement. Successful implementation of an EnMS requires a cultural change within an organisation and commitment at all of its levels and functions, especially top management. ISO 50001 states that an organisation shall determine external and internal issues, understand the needs and expectations of interested parties and determine the risks and opportunities that need to be addressed to achieve the intended outcomes of its EnMS and to improve its energy performance. The new version conforms to ISO's requirements for management system standards, including the incorporation of a high-level structure, identical core text, and common terms and definitions, thereby ensuring a high level of compatibility with other management system standards, including ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. The main changes from the previous edition are as follows: Adoption of ISO’s requirements for management system standards to ensure a high level of compatibility with other management system standards Support of integration with strategic management processes Clarification of language and organisation Stronger emphasis of the role of top management Terms and definitions have been updated and placed in context order Inclusion of new definitions, including “energy performance improvement” Clarification on exclusions of energy types Clarification of energy review Normalization of energy EnPIs and EnBs Addition of details on energy data collection plans (previously energy measurement plans) and related requirements Clarification of EnPI and EnB text to provide a better understanding of these concepts
