Introduction to ISO 50001

ISO 50001 is an international standard for Energy Management Systems (EnMS), providing a systematic framework for organizations to continually improve their energy performance, increase energy efficiency, and reduce energy consumption-related costs and greenhouse gas emissions.
Originally published in 2011 and revised in 2018, the updated version strengthens the strategic approach to improving energy performance.
This standard applies to all organizations regardless of size, type, or sector and is especially valuable in energy-intensive industries such as manufacturing, construction, and services.
