The ACV ZNI 2050 project, led by the Technology Assessment group, aims to perform a comprehensive,multi-criteria Life Cycle Assessment of four prospective energy transition scenarios for the island of La Réunion up to 2050, with a detailed focus on electricity production, distribution, and consumption. The study combines advanced prospective LCA and energy-system modeling tools developed by PSI—namely Brightway, Premise, Pathways, and Edges—to build scenario-based future inventories, quantify environmental impacts across time (2025–2050), and regionalize impact indicators (e.g., water scarcity, land use, resource criticality) using spatially explicit characterization factors.
