Energy management standards

ISO 50001: overview

In the context of energy management (EMS), the reference standard is ISO 50001. Published in 2011 and revised in 2018, it aims to provide a framework for integrating the issue of energy into the management practices of organisations in order to improve their energy performance. Energy-intensive companies will be particularly interested in the objectives of this standard and their benefits:

  • to promote energy efficiency throughout the supply chain;
  • to promote organisational aspects: identify best practices, reinforce good behaviour;
  • to promote technical factors;
  • to facilitate improvement in the context of greenhouse gas emission-reduction projects;
  • to establish a communication scheme on the management of energy resources;
  • to ensure integration with other management systems already in place (health and safety, quality, environment, etc.).

Parties involved in the process:

  • management must commit to this process and lay the foundations
  • the Energy Manager will be the Management representative and will bear responsibility for, and have authority over, the operation of the SME
  • all business functions, i.e. potentially each employee in their daily tasks having an impact on energy performance

How ISO 50001 works:

The ISO 50001 process involves two successive work phases:

  • Planning
    • Management commitment
    • development of an energy policy, a document defining the company's commitment
    • Energy Planning including the Energy Review, establishing reference consumption figures and energy performance indicators, and defining energy objectives and targets
    • maintaining an action plan
  • Cyclical operational phase based on the following requirements:
    • implementation, including arranging the purchase of equipment, energy services, products and equipment
    • checking (monitoring, legal and other requirements and management of non-conformities)
    • management review (annual management review)

Implementing an ISO 50001 system is a long-term project (approximately 18 months until certification).

ISO 50001 certification by an accredited external organisation ensures that the organisation meets all of the requirements of the standard.

ISO 14001: the alternative through environmental management

ISO 14001 is an international standard published in 1996. It sets out the requirements for implementation of an environmental management system based on a continuous improvement cycle and the aspects of this topic that apply to the company:

  • emissions into the air
  • discharges into water
  • discharges into soil
  • use of raw materials and natural resources
  • use of energy
  • energy produced (vibrations, heat, etc.)
  • waste and by-products


Benefit from the full potential of your ISO 14001 process by including energy!

An ISO 14001 certified company can therefore include energy-related matters in its scope of certification, but in a less specific and detailed way than covered by ISO 50001.

The current version of the standard is ISO 14001:2015.
