The water footprint community in LCA and outside LCA have been discussing their different approaches for many years already. The former quantifying potential impacts from water use and the latter aggregating inventory data (different types of water use) along the supply chain without impact assessment characterization. The two communities continue to clarify the reasoning behind their approaches in this exchange of publication and the intended use of each methodology. To this end Stephan Pfister et al. recently published a paper called: Understanding the LCA and ISO water footprint: A response to Hoekstra (2016) “A critique on the water-scarcity weighted water footprint in LCA”.
