Consensus building on the development of a stress-based indicator for LCA-based impact assessment of water consumption: outcome of the expert workshops
Établissement d'un consensus sur le développement d'un indicateur de stress pour l'évaluation des impacts de la consommation d'eau en ACV : résultats des ateliers d'experts
Résumé
A series of three expert workshops, including non- LCA experts from hydrology, eco-hydrology, and water supply science, was organized specifically on the topic of a generic stress-based midpoint indicator. They were held in Zurich on 10th September, in San Francisco on 5th October and in Tsukuba on 27th October 2014. In total 49 experts attended. The specific objectives of the workshops were twofold. First, it was to present the identified options of the stress-based indicator narrowed down by the active members of WULCA during the first 8 months of the project and to receive comments on the relevance, usefulness, acceptability, and focus of the selected indicator. Second, the workshop covered different challenges in the modeling of the indicator and presented the experts with background information and specific questions. This paper summarizes the discussions and outcome of these workshops. Where no agreement was reached, the working group of active members is considering all inputs received and continues the work.
