TS ISO 46001/Amd 1

TS ISO 46001/Amd 1. OFFICIAL SCOPE IS UNAVAILABLE. This amendment updates the ISO 46001 framework for water efficiency management systems with climate action-related changes. A water efficiency management system is a management-system approach that helps an organization understand, monitor, reduce, and continually improve its water use performance; in practice, the topic is not only about equipment, but also about objectives, data tracking, operational control, and improvement cycles.

What a water efficiency management system addresses

In general technical terms, such systems focus on making water abstraction, use, consumption, discharge, and loss points visible. For organizations, this means identifying where water is spent in processes, locating improvement opportunities, and managing performance in a measurable way. A management-system approach brings together policy, responsibilities, planning, implementation, monitoring, and review.

Why climate action changes matter

Climate action-related changes place water efficiency within a broader context of environmental resilience and emissions reduction. Water is closely linked to energy through treatment, distribution, and heating/cooling processes, so water efficiency improvements often support climate objectives as well. This amendment should be understood as a change document built on the parent standard, incorporating updates connected to climate action rather than standing alone as a complete technical scheme.

• A management-system approach for organizing organizational water use and performance
• Monitoring, target-setting, and continual-improvement principles
• Updated terms, wording, and guidance linked to climate action
• An amendment to the ISO 46001 parent standard
