Emmanuel Combet is economist at the Centre International de Recherche sur l’Environnement et le Développement in Paris (CIRED). He received his master’s degrees in engineering and economics in 2007 and his phD in economics from the Ecole des Hautes Etudes en Sciences Sociales in 2013. His doctoral dissertation “Carbon taxation and social progress” broadly examined the design and the political economy of a carbon tax reform in France. The objective of reducing CO2 emissions was jointly analysed with the other goals of tax reform (employment, competitiveness, redistribution, social protection and public finance). He currently conducts theoretical and applied research on the evaluation of green tax reforms, with a particular focus on their macroeconomic and distributive consequences. He also contributes to the development of new simulation models and uses them to explore the main economic trade-offs and possible compromises between policy objectives.
