Vivien Fisch-Romito is researcher at the Institute of geography and sustainability (IGD) since March 2023. He's interested in investigating the dynamics of energy supply and demand along low-carbon carbon pathways and assessing their feasibility across technological and economic dimensions through different methodologies: economic-environment-energy integrated assessment modelling, microsurveys analysis, data science, scenarios. He is now working on modelling energy sufficiency in the Swiss housing and mobility sectors to produce scenarios of alternative provisioning systems and consumption levels. He was Contributing author of the IPCC Sixth Assessment Report with the Working group III, working on the chapter 2 about global greenhouse gas emissions trends and drivers.
Prior to joining the institute, he was post-doctoral researcher in the Renewable Energy Systems group of University of Geneva, working on the incorporation of societal factors in energy system models to improve the accuracy of national long-range energy projections. He obtained his PhD in economics at Centre International de Recherche sur l'Environnement et le Développement (CIRED) in Paris where he analyzed the global infrastructure stock dynamics as a key factor for climate-development conciliation.
