Résumé
Net-zero emissions scenarios (NZE) generally do not focus on imported green-house gases emissions. On an other side, input-ouput environmental assessments of decarbonization scenarios often miss the macroeconomic consequences of the energy transition. In this study, we built and evaluated the material and environmental footprints of detailed and coherent NZE scenarios for France, describing a various range of mitigation actions and transition ideologies, through a bottom-up coupling with hybrid input-output analysis (HIO). We discuss the relative effectiveness of these actions, classified into sufficiency, efficiency and substitution categories. This highlights the efficiency of sufficiency actions to reduce both material and carbon footprints.
