Anne-Marie Boulay graduated from Chemical Engineering at McGill University in 2006. After working as a consultant, she integrated CIRAIG’s team at École Polytechnique of Montreal and obtained her Ph.D. in 2013 on the assessment of water use impacts in LCA. It is for this work that she received the SETAC Europe Young Scientist Award in 2014. After more than 10 years on the topic of Life Cycle Impact Assessment, she has become an expert on water footprint, providing water footprint training for UNEP and ISO in developing countries around the world and she is the Canadian chair of ISO sub-committee on Life Cycle Assessment (TC207/SC5). She is now an Assistant Professor in Chemical Engineering at Polytechnique Montreal and CIRAIG. She is currently chairing the WULCA working group on water use in LCA of UN Environment, the LEAP working group of FAO on water footprint and the MARILCA working group (UN Environment and FSLCI) on marine impacts, specifically plastic litter, in LCA. These working groups are leading the international consensus building processes and the scientific work into achieving harmonized methods for assessing important impact pathways in LCA, involving key method developers and stakeholders through international collaborative efforts.
