Hybridization challenges in energy-economy integrated models and representation of the low carbon transition : An application to the Brazilian case

Abstract : This thesis provides insights about the hybridization challenges in energy-economy integrated models and about the integrated representation of the low carbon transition, and proposes an application to the Brazilian case. Noting the existing gap between the framing of transition issues towards low carbon economies and the results brought by global integrated models, it provides a guide of the available model toolbox which brings a new view on the internal vision of models about energy-carbon-economy transformation pathways. This makes it possible to better delimit the areas of competence of existing tools and to understand some of their limitations. Our work especially underlies the relevance to work under a hybrid approach which articulates a macroeconomic framework with engineering based representations in order to improve the credibility of the assessments produced and we detail the methodological issues to build multi-sector energy-economy hybrid models. Part of the methodological principles are applied to build a tool to analyze the low carbon transition of the medium run in Brazil. We show how a carbon tax policy makes it possible to articulate several policy objectives until 2030 targeting purchasing power, competitiveness, employment and income distribution, beyond climate goals. Our diagnostic underlies the importance of the structural specifics of the energy-economy context in Brazil and of macroeconomic mechanisms linked to trade and labor market rigidities, which are often overlooked in existing studies. We eventually provide specific insights about the articulation between climate and oil policy in Brazil.
