Mandatory characterization of blue water consumption using region-specific scarcity factors (e.g., AWARE, Water Stress Index). Green water excluded.
Optional but required if goal includes water quality. Uses fate, exposure, and effect factors for eutrophication, acidification, ecotoxicity, etc.
Here is the based on your request for “ISO 14046 Water Footprint PDF 19” — which refers to ISO 14046:2014 Environmental management — Water footprint — Principles, requirements and guidelines , specifically in relation to clause/section 19 (typically Annex B or an informative section in the 2014 document).

Since I cannot distribute a copyrighted PDF, below is a of ISO 14046:2014, including the equivalent of section/clause 19 (which is actually Annex B in the official standard — “Example of water footprint inventory, impact assessment and interpretation”). ISO 14046:2014(E) Environmental management — Water footprint — Principles, requirements and guidelines Clause 19 — Annex B (Informative) Example of water footprint inventory, impact assessment and interpretation B.1 General This annex provides a simplified example to illustrate the application of the water footprint assessment methodology described in Clauses 5 to 10. The example is based on a hypothetical product system: 1 kg of refined white sugar produced in a tropical region .
