The document discusses water footprinting and managing water resources along the supply chain. It provides context on water scarcity issues around the world and highlights the hidden water use in supply chains. The key point is that water footprinting can make the link between consumption in one place and impacts on water systems elsewhere. It examines approaches for assessing water footprints through volumetric and impact assessments and references the development of ISO standards for water footprinting methodology.
