SUMMARY
According to NGUYEN and BREUCKER, energy sobriety, once seen as a temporary response to energy crises, must now become part of a structural policy. In this note from the Institut Jacques DELORS, the authors explain how France must rethink its energy strategy to achieve its climate objectives. The success of the new energy sobriety plan, scheduled for autumn 2024, hinges on binding measures, control of the biggest emitters, and investment in low-carbon infrastructure. Sobriety is not just about reducing emissions; it also strengthens economic and social resilience, bringing geostrategic and health benefits. The report recommends avoiding short-termist approaches and institutionalizing measures to avoid the risk of "demobilization" once crises have subsided. The importance of sobriety policies is essential for a successful ecological transition, guaranteeing energy security while reducing social inequalities and climate impacts.
