ISO 50001



ISO 50001 specifies requirements for establishing, implementing, maintaining and improving an energy management system. The purpose of ISO 50001 is to enable an organisation to achieve continual improvement in their energy performance through a systematic approach.

ISO 50001 specifies requirements applicable to energy use and consumption, including measurement, documentation and reporting, design and procurement practices for equipment, systems, processes and personnel that contribute to energy performance.

The ISO 50001 standard is based on the Plan-Do-Check-Act methodology which encourages the organisation to put in place actions to reduce and monitor energy use. The following steps form the
basic structure of ISO 50001.

  • Plan: Conduct the energy review and establish the baseline, energy performance indicators (EnPIs), objectives, targets and action plans necessary to deliver results in accordance with opportunities to improve energy performance and the organization’s energy policy.
  • Do: Implement the processes.
  • Check: Monitor and measure processes against energy policy and objectives, and report the results or take any necessary corrective action.
  • Act: Take actions to continually improve energy performance.


  • Increase energy efficiency thus reducing cost
  • Reduce environmental impacts
  • Increase level of assurance of legal and internal compliance
  • Identify the types of variables that are affecting energy use
  • Increase profits through reducing excessive costs
  • Uphold best practices by reinforcing proper energy management processes
  • Encourage commitment within the organisation by introducing a systematic approach on sustaining of energy efficiency
