ISO 50001:2018

Energy Management System

What is Energy Management?

The ISO 50001 standard for energy management systems (EnMS) can help your organisation improve its energy efficiency.

As well as saving you money by reducing energy consumption, it will also help you reduce your carbon footprint. This in turn can enhance your brand with customers, employees and other stakeholders.


The ISO 50001 standard can help your business improve its business processes, use resources more efficiently and save money by cutting your energy consumption and carbon emissions. The standard is suitable for all businesses in the private and public sector from sole traders to multinational organisations.


Benefits of ISO 50001 

  1. A significant improvement of the energy performance level from an initial energy baseline.

  2. A systematic approach (plan-do-check and act) that leads to continuous energy efficiency improvement. ISO 50001 enables organisations to:

  • Develop a policy for more efficient use of energy

  • Fix energy efficiency targets and objectives to meet the policy

  • Use data to better understand and make decisions concerning energy use and consumption

  • Measure the results of energy efficiency improvements

  • Review the effectiveness of the energy policy

  • Continually improve energy management

  • ISO 50001 supports the development of an energy policy and contributes to the structure of an energy plan to achieve targets.

  • ISO 50001 facilitates engagement (commitment and agreement) of management and has a positive contribution towards the energy targets.

  • An ISO 50001-based EnMS creates awareness and a commitment about energy (i.e. consumption, use, efficiency, renewable sources) within the organisation.

  • ISO 50001 improves the ability of organisations to manage energy risks concerning possible impacts in an efficient and effective way.

  • ISO 50001 strengthens the competitiveness of organisations and reduces their vulnerability with respect to energy price fluctuation and availability of energy.

  • ISO 50001 allows the establishment of a benchmarking process.

  • An ISO 50001-based EnMS allows organisations to gain credible external visibility of energy saving actions.

  • An ISO 50001-based EnMS provides a better understanding between predictable energy demand and supply.

  • An ISO50001-based EnMS reduces energy costs and improves profitability.

In addition, implementing ISO 50001 yields significant benefits beyond energy and energy cost savings. Early adoption experiences have shown that conformance with the standard results in some non-energy benefits such as greater productivity and lower maintenance needs. In many cases significant energy and energy cost savings were achieved with minimal or no capital investment. This is because ISO 50001 fosters a change in culture that engages and empowers employees to identify and address energy-saving opportunities as they materialize. Then, by continuously monitoring and improving energy efficiency, companies achieve persistence in energy savings.
