What is BS EN ISO 50001:2011?

BS EN ISO 50001:2011 stipulates the requirements for an energy management system. Designed to make the most from energy technology, this standard helps management to reduce their energy consumption, while boosting their overall energy conservation. This includes reduced energy costs and carbon emissions, and a more secure supply of energy. BS EN ISO 50001 helps organizations to take on a systematic approach to continually improve their energy performance and establish a credible, certified reputation.

How does it work?

BS EN ISO 50001:2011 helps to improve management techniques by providing a comprehensive scope of requirements to run an efficient energy management system. These include energy policies, planning, legal requirements, as well as energy reviews, baseline and performance indicators. The standard also explains how to demonstrate competence, operational control and best practice procurement of energy services, products and equipment.

What’s new?

BS EN ISO 50001 is similar to BS EN 16001, but its approach offers organizations a better reassurance of internationally recognised best practice.

Who should buy it?

  • Anyone wanting to reduce energy costs, reduce carbon emissions and improve their organization’s reputation
  • Those who want to develop a deeper understanding of internationally recognised best practice energy management
  • Users of ISO 14001 who would like to develop their energy management systems
  • Anyone responsible for the planning and implementation of an energy management system
  • Quality assessors
  • Energy technology consultants
