Water Footprint

ISO 14046 Life Cycle Assessment - Water Footprint - Requirements and Guidelines

ISO 14046 Water Footprint is a standard currently being created within the International Organisation for Standards (ISO) under its working group ISO TC 207 SC5 WG8.

ISO 14046 aims to provide a framework of good practice that demonstrates the important elements for measuring the water footprint of products, processes or organisations that any ISO-compliant method should address as part of a water footprint measurement.

How will it help?

ISO 14046 will be able to help industry understand and improve water use and its environmental impact through:

  • identifying opportunities to improve environmental performance related to water use
  • assessing the magnitude of environmental impacts
  • managing risk strategically
  • setting priorities
  • informing decision-makers for strategic planning
  • thinking about process and product design

Tell me more…

ISO 14046 defines how different types of water sources and types of degradation in water should be included. It considers local environments such as dry or wet areas, and geographical and temporal conditions. It looks at both water inventory and the impact of water extraction, use and return on the environment.

Because it takes a Life Cycle Assessment (LCA) approach, it uses LCA practice as set out in ISO 14040 and ISO 14044. The standard looks up and down the supply chain, from raw material to end-of-life management.
