What is ISO 50001?

"Broad implementation of ISO 50001 could drive cumulative energy savings of 62 exajoules by 2030, saving over $600 billion in energy costs and avoiding 6,500 Mt of CO2 emissions, equivalent to removing 215 million passenger vehicles from the road."

 “Global Impact Estimation of ISO 50001,” LBNL, 2016

Get Started with DOE Programs:

  • 50001 Ready: Self-paced, no-cost way for organizations to build a culture of structured energy improvement that leads to deeper and sustained savings
  • SEP 50001: Certification for ISO 50001 plus verified energy performance improvement

Transitioning from the 2011 version?

An energy management system (EnMS) integrates energy management into existing business systems, enabling organizations to better manage their energy and sustain achieved savings. Companies use an EnMS to establish the policies and procedures to systematically track, analyze, and improve energy efficiency.

ISO 50001, the global standard for energy management systems, helps organizations continually improve energy performance as part of daily business practice. This standard shares the Plan-Do-Check-Act structure to continual improvement used in ISO 9001 (quality management), ISO 14001 (environmental management), and other management systems. 

ISO 50001 was developed by experts from around the world who participate in the ISO/TC 301, the group that developed the portfolio of ISO 50001 standards and guidance documents. As of March 2019, ISO TC 301 has published 16 standards and has 7 more under development.

ISO 50001:2018, the revised version of the standard, was published on August 21, 2018 to increase its clarity and applicability for businesses and organizations around the world. DOE is updating its programs to align with the revised standard.

DOE’s Advanced Manufacturing Office recognizes the importance of energy performance in boosting the cost-competitiveness of U.S. businesses. DOE's 50001 Ready and Superior Energy Performance 50001 (SEP 50001) programs provide guidance, tools, and protocols to drive deeper, more sustained savings from ISO 50001.

U.S. DOE, through the American National Standards Institute (ANSI), has worked actively with scores of countries to develop the ISO 50001 standard and promote its adoption. ISO 50001 was originally published in June 2011 and revised in August 2018.  DOE and industry have jointly invested over $3 million to accelerate market-driven uptake of the standard—delivering business value to companies and organizations nationwide.

International governments are collaborating to accelerate worldwide use of energy management systems in industry and commercial buildings through the Clean Energy Ministerial Energy Management Working Group (EMWG).
