Stéphane Hallegatte

Senior Economist, Climate Change Group

Stéphane Hallegatte joined the World Bank as senior economist in September 2012 after 10 years of academic research in environmental economics and climate science for Météo-France, the Centre International de Recherche sur l’Environnement et le Développement, and Stanford University. His research interests include environmental economics, risk management, adaptation to climate change, urban policy, climate change mitigation policies, and green growth.

He has worked on natural disaster and risk-management policies at local and national scales, including on cases in Europe (following the storm Xynthia in 2010), North Africa (Morocco,Tunisia), India (Mumbai), and the United States (New Orleans after Hurricane Katrina). He has worked extensively on decision-making under uncertainty, with applications for climate change adaptation in the water sector and risk management. He participated in the development of the French National Adaptation Plan to Climate Change and supported the application of the same development methodology in Vietnam. He is involved in World Bank projects that include decision-making under uncertainty, early warning and risk management and disasters, and strategies for green growth and climate change mitigation. 

Mr. Hallegatte is lead author of the IPCC chapter “the economics of adaptation” in the working group on impacts and adaptation and in the Synthesis Report that summarizes the 5th assessment report. He is the author of dozens of articles published in international journals in multiple disciplines and of several books, including Green Economy and the Crisis: 30 Proposals for a More Sustainable France and Risk Management: Lessons from the Storm Xynthia. He also co-led the World Bank reports Inclusive Green Growth: The Pathway to Sustainable Development, published in 2012 and Decarbonizing Development in 2015, and was member of the core writing team of the 2014 World Development Report Risk and Opportunity: Managing Risks for Development. Most recently, he led the World Bank report Shock Waves: Managing the Impacts of Climate Change on Poverty, published in 2015 just before the Paris conference on climate change. He was the team leader for the World Bank Group Climate Change Action Plan, a large internal coordination exercise to determine and explain how the Group will support countries in their implementation of the Paris Agreement.

He has taught at the Ecole Polytechnique, Science Po Paris, the Ecole Nationale de la Météorologie, and the Normal University in Beijing, and is the editor in charge of economics for the international journal "WIRES Climate Change." He was a member of the French delegation for the approval plenary of the 4th assessment report of the IPCC in 2007, and for Conferences of Parties of the United Nations Framework Convention on Climate Change from 2008 to 2010.

Mr. Hallegatte holds engineering degrees from the Ecole Polytechnique (Paris) and the Ecole Nationale de la Météorologie (Toulouse), a master's degree in meteorology and climatology from the Université Paul Sabatier (Toulouse) and a Ph.D in economics from the Ecole des Hautes Etudes en Sciences Sociales (Paris).
