ISO 50001:2011

Certification of energy management systems
(As a result of the COVID-19 pandemic, IAF has extended the transition period by 6 months, i.e. ISO 50001:2011 will cease to be valid on 20 February 2022 and be replaced by ISO 50001:2018. Already from 21 August 2020, only audits in accordance with ISO 50001:2018 are allowed to be carried out.)


Energy has become a big issue in society and in enterprise. The ISO 50001 standard is an international definition of the requirements in terms of systematic energy management. Companies demonstrating fulfilment of these requirements can increase their energy efficiency and reduce the environmental impact caused by their energy use. They can show that their actions are prompted by their own sense of duty and commitment and that they have due regard for legal requirements. SQS has years of professional experience and extensive expertise in validation and certification processes relating to energy use and carbon footprint. This explains why the SQS certificate for energy management systems conforming to ISO 50001 is held in high regard and accepted all over the world.


ISO 50001 forms the basis for the continuous improvement of energy management and energy efficiency, including the reduction of environmental impact caused by energy use.

Target groups

Companies and organisations of all sizes operating in all sectors.


3 years - there is an annual audit to ensure that standards are being maintained and a recertification audit after three years.


The SQS certificate of conformity with ISO 50001 has international validity and is recognised worldwide through the IQNet partnership.


ISO 50001 is compatible with ISO 14001 (environmental management) and ISO 9001 (quality management) and with all other management system standards.
