• Encourages transparent reporting and communication of climate actions associated with energy management

Who should comply? Organizations aiming for or maintaining ISO 50001 certification, particularly those seeking to demonstrate their commitment to climate goals, greenhouse gas (GHG) reductions, or broader sustainability frameworks (such as ESG).

Practical implications: The amendment enables organizations to:

• Transform energy management into a factor for climate action

• Support compliance with future climate-related legal and reporting obligations

• Integrate energy efficiency with emissions targets and broader sustainability objectives

Notable features:

• Bridges the gap between energy management, operational goals, and climate change

• Supports organizations in preparing for evolving environmental compliance demands
