This International Standard specifies principles, requirements and guidelines related to water footprint
assessment of products, processes and organizations based on life cycle assessment (LCA).
This International Standard provides principles, requirements and guidelines for conducting and
reporting a water footprint assessment as a stand-alone assessment, or as part of a more comprehensive
environmental assessment.
Only air and soil emissions that impact water quality are included in the assessment, and not all air and
soil emissions are included.
The result of a water footprint assessment is a single value or a profile of impact indicator results.
Whereas reporting is within the scope of this International Standard, communication of water footprint
results, for example in the form of labels or declarations, is outside the scope of this International
Standard.
NOTE – Specific requirements and guidelines for organizations are given in Annex A.
