The current version of the global Energy Management System Standard, ISO 50001:2011 was issued in June 2011 and has been adopted in countries across the globe.
There is a global campaign in progress to get 50,000 organisations certified to ISO 50001 by 2020. This is supported by the Governments of Canada, USA and Mexico.
In recent years the ISO 50001 Technical Committee have been meeting to revise the current standard to a new version which is expected to be published in June 2018.
The main change is the restructuring of ISO 50001 to the High Level Structure (HLS) which his being applied to ISO standards. In effect, it is “standardising” the structure of standards. This brings about some changes in the new version such as the removal of the need for a Management Representative and replaced by an energy management team.
The HLS was introduced to the Environmental Management System Standard, ISO 14001, in the 2015 version.
Certification lasts for three years so there will be a transition period for those currently holding certification to ISO 50001:2011 to transition to ISO 50001:2018 by June 2021 at the latest, depending on the date of certification in the three years up to June 2018.
The release of the new standard may be delayed after June 2018. National accreditation bodies, like UKAS, and the certification bodies then need to gear up to the new standard and that could take up to six months. So the earliest likely time a certification body would be ready to certify to the new standard is January 2019.
So if an organisation wants to get certification before this date it would make sense to design the EnMS to
ISO 50001: 2011.
