ISO 50001:2018 is an international standard developed by the International Organization for Standardization (ISO) that outlines the best practices for establishing, implementing, maintaining, and continually improving an Energy Management System (EnMS).

This standard helps organizations systematically manage energy performance, including energy efficiency, energy use, and consumption. It offers a structured approach to integrating energy management into day-to-day operations, ensuring sustainable energy usage and cost savings.

Implementing ISO 50001 enables businesses to demonstrate their commitment to efficient energy management and continuous improvement in performance. It emphasizes optimizing energy use, reducing waste, improving energy security, and supporting environmental sustainability—complementing other management system standards such as ISO 9001 (Quality Management) and ISO 14001 (Environmental Management).
