About ISO 50001:2018 Energy Management System

The standard specifies the requirements for establishing, implementing, maintaining and improving an energy management system, whose purpose is to enable an organization to follow a systematic approach in achieving continual improvement of energy performance, including energy efficiency, energy security, energy use and consumption. The standard aims to help organizations continually reduce their energy use, and therefore their energy costs and their greenhouse gas emissions.

ISO 50001 was originally released by ISO in June 2011 and is suitable for any organization, whatever its size, sector or geographical location.[2] The second edition, ISO 50001:2018 was released in August of 2018.


Organizations of all types and sizes increasingly want to reduce the amount of energy they consume. This is driven by the need or desire to:

  • reduce costs
  • reduce the impact of rising costs
  • meet legislative or self-imposed carbon targets
  • reduce reliance on fossil fuels
  • enhance the entity’s reputation as a socially responsible organization.
