Overview

Gaëlle Le Treut is an environmental economist. She focuses her research on the energy transition in developing countries, using in particular the GEMMES macroeconomic modelling tool.

Gaëlle Le Treut joined AFD’s macroeconomic modelling team at the end of 2022, after ten years of academic research. She is currently working on the development of the GEMMES model in Vietnam and in Morocco. She uses macroeconomic modelling coupled with sectoral models to establish a dialogue with public policies on the implications of low-carbon strategies.

She holds a PhD in economics (Ecole des Ponts - Université Paris Est) from the Centre international de recherche sur l’environnement et le développement (CIRED) and a diploma in energy engineering (Grenoble-INP, ENSE3). Her research focuses on the structural change caused by the energy transition and the macroeconomic consequences of implementing environmental policies such as the carbon tax.  

Before joining AFD, she was a researcher at CIRED. In particular, she was part of the international research network IMACLIM, bringing together different research institutes for the co-construction of national IMACLIM models as decision support tools for the energy transition. In addition to researching the French case, she has worked with Argentina (Bariloche Foundation), Brazil (COPPE – Federal University of Rio de Janeiro, where she completed a post-doctorate between 2018 and 2020), Mexico, Algeria and Nigeria.
