The environmental assessment of energy systems is crucial for supporting the transition to more sustainable models. Life Cycle Assessment (LCA) helps identify the most efficient supply chains and informs strategic decisions. However, traditional approaches to this methodology have limitations in a context where energy systems are rapidly evolving. Therefore, the LCA methodological framework must be developed to better reflect the complexity of transforming energy systems.This session aims to explore three key dimensions:
1. Prospective: Anticipating technological developments, changes in the energy mix, and societal dynamics through exploratory scenarios.
2. Dynamic: Accounting for temporal variations in environmental impacts, efficiency, and energy consumption patterns.
3. Spatial: Integrating geographic specificities of resources, uses, and impacts to refine analyses.
Through case studies and methodological reflections, this session seeks to identify improvement levers for evaluations that incorporate these three dimensions. The goal is to optimise energy planning and develop innovative tools tailored to the current challenges of the energy transition
