ISO 50001 Energy Management Standard

About DOE and ISO 50001

The U.S. Department of Energy (DOE) played a critical role in developing ISO 50001—the world's first global energy management system standard. ISO 50001 promotes the widespread adoption of best practices and drives investment in energy efficiency. DOE actively supports its broad implementation to achieve powerful benefits to U.S. businesses and to the nation.

U.S. industrial facilities, buildings, and other organizations earning certification under ISO 50001 will signal to national and international customers their responsible stewardship of energy resources. By maintaining a comprehensive energy management system (EnMS), these organizations will enjoy the associated benefits of carbon reduction, energy-related risk reduction, and certified sustainability—all of which are likely to increase in value.

On a national scale, implementation of ISO 50001 will help address national priorities for energy security, carbon reduction, and economic competitiveness. Globally, the standard could influence up to 60% of the world's energy use. Learn more:

ISO 50001

ISO 50001 provides organizations with an internationally recognized framework for efficiently managing and improving their energy performance. The standard addresses the following:

  • Energy use and consumption
  • Measurement, documentation, and reporting of energy use and consumption
  • Design and procurement practices for energy-using equipment, systems, and processes
  • All variables affecting energy performance that can be monitored and influenced by the organization.

ISO 50001 is based on the Plan-Do-Check-Act approach to continual improvement, which supports energy performance improvement over time based on the best data available to the organization. Continual improvement of energy performance requires a comprehensive energy management system involving a variety of stakeholders within an organization. The standard does not prescribe minimum performance criteria, energy reductions, or targets.

DOE Roles

Developing ISO 50001 and Related Standards

The International Organization for Standardization (ISO), the world's largest developer and publisher of international standards, identified energy management as a priority due to the significant potential to save energy and reduce greenhouse (GHG) emissions worldwide. ISO created Project Committee (PC) 242 to carry out the development of ISO 50001. DOE supported the American National Standards Institute's (ANSI) role as Secretariat of PC 242 (serving jointly with Brazil), to lead the international development of ISO 50001. In addition, DOE contributed actively to the U.S. Technical Advisory Group (TAG), the U.S. delegation to ISO PC 242. The U.S. TAG led international negotiations to ensure that ISO 50001 preserves the U.S. emphasis on management support and data-driven energy performance.

Moving forward, DOE will support the transition of PC 242 to a Technical Committee (TC) 242, which will update ISO 50001 as needed and develop a family of related standards. DOE support will help to ensure that the new standards will be consistent with U.S. energy policy and strategy.

Implementing ISO 50001

To ensure U.S. companies and organizations derive maximum benefit from ISO 50001, DOE is working with standards authorities and energy management and industry experts to create a supportive framework for implementation. Activities include:

  • Providing DOE eGuide for ISO 50001, step-by-step guidance and resource to assist organizations develop and implement an energy management system based on ISO 50001.
  • Developing a training curriculum for ISO 50001 implementation experts.
  • Developing auditor requirements to assess energy management systems for conformance to ISO 50001.
  • Credentialing professionals to assist organizations in implementing ISO 50001 and to audit energy management systems for conformance to ISO 50001.
  • Supporting ANAB-accreditation of certification bodies to manage the ISO 50001 auditing process.

In addition, DOE is supporting implementation of the ISO 50001 standard in industrial and commercial facilities through the development of the U.S. Superior Energy Performance (SEP) certification and verification program and Global Superior Energy Performance (GSEP) partnership. DOE is a member of the U.S. Council for Energy Efficient Manufacturing that has partnered together to develop the industrial Superior Energy Performance certification program.

DOE's supportive framework for ISO 50001 implementation will ensure that this voluntary standard remains highly regarded by the market. Holding qualified individuals and organizations to rigorous requirements will bolster public confidence in the value of ISO 50001 certification. These requirements will promote the proper application of ISO 50001 and maintain the market value of certification.

DOE Partners in Implementation Support

  • ANSI-ASQ National Accreditation Board (ANAB) will accredit certification bodies that will employ Certified ISO 50001 Auditors to assess an organization's conformance to ISO 50001. Individuals who pass the national exam and meet additional performance requirements in accordance with the DOE-approved scheme will be Certified ISO 50001 Auditors.
  • To assist organizations in implementation of ISO 50001, DOE is working with energy management experts and ANSI to create an ANSI-accredited program for Certified Practitioners in Energy Management Systems.
  • Additionally, DOE is working with ANSI, ANAB, and energy management experts to create advanced qualifications for Certified Auditors and performance verifiers who will certify facilities to the Superior Energy Performance program.
  • DOE is working with the U.S. Council for Energy-Efficient Manufacturing (U.S. CEEM) to test and refine the requirements of the Superior Energy Performance program.

Activities supporting the implementation of ISO 50001 are coordinated by several DOE offices:

Potential Energy Savings

If widely adopted, the voluntary ISO 50001 standard could influence up to 60% of the world's energy usePDF across many economic sectors. Factors expected to drive broad adoption of ISO 50001 include the growth of corporate sustainability programs and the spread of energy management standards along the manufacturing supply chain. Companies may also find the resulting energy and carbon reductions increasingly valuable as a means to comply with possible carbon reduction initiatives or to enhance their corporate environmental practices.
