Résumé : | Food consumption is responsible for most global water consumption and associated environmental consequences. Therefore, quantifying and monitoring the water footprint (WF) of food consumption patterns is relevant to support policymaking toward sustainable diets. Although multiple WF approaches are available, such as Water Footprint Assessment (WFA) and the model AWARE (Available Water Remaining) for supply chains analysis, the latest is considered the reference after following an international consultation process. This research aims to develop a comparative methodological approach between the volumetric blue water footprint assessment (WFA), a pressure method, and the scarcity-weighted WF AWARE model as an impact method to evaluate the WF of EU27 food consumption. Due to limited blue WFA data availability, two scopes were considered: an aligned scope (cradle to farm gate) comparing both methods and a full supply chain scope (cradle to grave) only possible with AWARE. In the aligned scope, almonds and cashew have the largest pressure and impact in both methods (per kg of product). EU food consumption has a WF pressure under an aligned scope of ≈54 m3/capita/year and an impact of ≈3525 m3 eq/capita/year. When considering the "full supply chain", WF impact due to EU food consumption increases by 30% (compared with the "aligned scope"), with wine and chocolate at the top of the ranking. Integration of WFA data within the LCA inventory could be explored when WFA data also covers indirect WF of background processes and other supply chain stages. |
