ISO 50001 with high-level structure

ISO 50001 is the most used business energy management standard in the world. Certification of an Energy Management System according to ISO 50001 helps organisation to implement an energy policy and properly manage energy aspects derived from their activity, such as services, facilities, products, etc., which translates into real, quantifiable savings of energy costs in organisations. ISO 50001 provides the tools needed to identify the activities that consume most energy, and which represent an 'energetic and economic leakage'. Once identified, organisations activate an action plan to minimise energy consumption in their own installations and systems, whilst maximising their energy efficiency. This contributes to an efficient and more sustainable use of energy, providing maximum assurance in the ISO 50001 management system.

The updated standard ISO 50001 provides the following new features and improvements:

  • Structural improvements: Just like other ISO standards, standard 50001 has a high-level structure, which improves alignment with other management systems, providing organisations with the integration of these systems.
  • Greater level of continual improvement: The updated version particularly focuses on the need to work on continual improvement as a key factor of an energy management system, whereby this improvement is more clearly linked to the information derived from the analysis and evaluation of the system.
  • Greater focus on business: The focus is placed on the business, thanks to the implementation of a more strategic and tactical Energy Planning Process. It also pays attention to comprehension, the organisation and its context.
  • Better energy performance: It boosts the capacity to improve energy performance, increasing metrics with an energy performance indicator, a reference energy performance indicator, and continual improvements to energy performance.
  • Plan, Analyse and Act: The new ISO 50001 particularly deals with data collection, for planning the energy management system and energy processes. It improves energy performance, complies with legal requirements and other requirements, and achieves the energy objectives.

AENOR helps you to benefit from energy efficiency grants provided by the government, submitting the report that proves that your company has made technological improvements to industrial equipment and processes, or certifying your ISO 50001 as a guarantee of the correct implementation of an energy management system.

The Certification of Energy Management Systems is intended for those organisations that want to demonstrate that they have introduced a system of energy management, make greater use of renewable or excess energy, and/or have systematised their energy processes, attempting to bring them into line with the energy policy of the organisation.

ISO 50001 on energy management systems is universal, and is applied to any organisation.

The Energy Management System is based on the PDCA (Plan-Do-Check-Act) cycle of constant improvement and is compatible with other energy saving and efficiency measures. This new standard has also been designed along similar lines to other management system standards such as ISO 14001 or ISO 9001, which makes it a complementary, compatible and integrable tool with other management systems.

Certified companies obtain:

  • The AENOR Certificate of Energy Management Systems.
  • A license to use of the AENOR Energy Management Mark.

Furthermore, organisations with management systems certified by AENOR have free access to the AENORnet and a subscription to the AENOR monthly magazine.​​

AENOR Mark on Energy Management
ISO 50001

In 2007, AENOR published Standard UNE 216301 Energy Management System, and at the end of 2011, it published European standard UNE-EN ISO 50001, whose requirements and principles are practically the same as those of the UNE standard it replaced.

Since 2007, AENOR has provided its services for certifying energy management and leading the market in accordance with ISO 50001.

Spain ranks eighth globally and sixth in Europe in terms of the number of certificates issued for Energy Management Systems, in accordance with standard ISO 50001, with 568 recognitions, according to the last ISO report.
