The new ISO 50001 has been published

Since this energy management standard was last published, both businesses and consumers have come to understand that their energy use impacts the environment we all share.

Natural resources continue to deplete, which places a greater emphasis on energy security. Energy costs are also rising, and organizations are under constant pressure to reduce overhead costs.

These pressures meant it was time to consider how the standard might better meet the needs of businesses and improve energy management systems (EnMS) altogether.

During the development process the standard also adopted Annex SL. The high level structure (HLS) was introduced to align the implementation process of ISO management systems so that it was easier to adopt multiple management systems within individual organizations.


The key changes to the standard include:

A stronger emphasis on the responsibility of leadership

  • Clarification of key concepts related to energy performance
  • Improved compatibility with ISO 14001 and other ISO management system standards, through the alignment to the HLS
  • Improved sections on data collection and normalization

The benefits of ISO 50001:

Decreased energy consumption and expenditures

  • Customer, statutory and regulatory compliance
  • Increased customer, stakeholder and consumer confidence in products
  • Improved risk management
  • Integration with other ISO management systems
