Biography
Stéphane Hallegatte is a Senior Climate Change Adviser at the World Bank. He joined the World Bank in 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 the economics of natural disasters and risk management, climate change adaptation, urban policy and economics, climate change mitigation, and green growth. Mr. Hallegatte was a lead author of the 5th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). 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 , Risk Management: Lessons from the Storm Xynthia , and Natural Disasters and Climate Change: An Economic Perspective . 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 reports Shock Waves: Managing the Impacts of Climate Change on Poverty , Unbreakable: Building the Resilience of the Poor in the Face of Natural Disasters , and Lifelines: the Resilient Infrastructure Opportunity. 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. 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).

    Macroeconomic Consequences of Natural Disasters: A Modeling Proposal and Application to Floods and Earthquakes in Turkey
    (Washington, DC: World Bank, 2022-02-22) Hallegatte, Stephane ; Jooste, Charl ; Mcisaac, Florent John
    Turkey is vulnerable to natural disasters that can generate substantial damages to public and private sector infrastructure capital. Earthquakes and floods are the most frequent hazards today, and flood risks are expected to increase with climate change. To ensure stability and growth and minimize the welfare impact of these disasters, these shocks need to be managed and accounted for in macro-fiscal and monetary policy. To support this process, the World Bank Macrostructural Model is adapted to assess the macroeconomic effects of natural (geophysical or climate-related) disasters. The macroeconomic model is extended on several fronts: (1) a distinction is made between infrastructure and non-infrastructure capital, with complementary or substitutability between the two categories; (2) the production function is adjusted to account for short-term complementarity across capital assets; (3) the reconstruction process is modeled in a way that accounts for post-disaster constraints, with distinct processes for the reconstruction of public and private assets. The results show that destroyed infrastructure capital makes the remaining non-infrastructure capital less productive, which means that disasters reduce the total stock of capital, but also its productivity. The welfare impact of a disaster—proxied by the discounted consumption loss—is found to increase non-linearly with direct asset losses. Macroeconomic responses reduce the welfare impact of minor disasters but magnify it when direct asset losses exceed the economy’s absorption capacity. The welfare impact also depends on the pre-existing economic situation, the ability of the economy to reallocate resources toward reconstruction, and the response of the monetary policy. Appropriate macro-fiscal and monetary policies offer cost-effective opportunities to mitigate the welfare impact of major disasters.

    Best Investments for an Economic Recovery from Coronavirus: An Illustration Based on the Fiji Climate Vulnerability Assessment to Pinpoint Stimulus Options
    (World Bank, Washington, DC, 2020-08-25) Fargher, Samuel ; Hallegatte, Stephane
    The COVID-19 crisis is causing massive suffering across the globe. In addition to the human consequences of the disease, containment measures to slow down and control the virus have deprived people of their livelihood and put many firms in a difficult financial situation. As a result, governments are planning massive stimulus packages to accelerate recovery once the health emergency is under control. To help governments think through investments for a green recovery, we proposed a sustainability checklist to screen potential projects and policies. To test how the sustainability checklist might work for a specific country, the checklist was applied to the Fiji Climate Vulnerability Assessment (CVA). The objective is to demonstrate how the checklist can be used as a screening, scoring, and prioritization tool to identify projects that create synergies between short-term needs and long-term objectives.

    'Building Back Better' in Practice: A Science-Policy Framework for a Green Economic Recovery after COVID-19
    (World Bank, Washington, DC, 2021-01) Zachariadis, Theodoros ; Giannakis, ,Elias ; Taliotis, Constantinos ; Karmellos, Marios ; Fylaktos, Nestor ; Howells, Mark ; Blyth, Will ; Hallegatte, Stephane
    As humanity’s current production and consumption patterns exceed planetary boundaries, many opinion leaders have stressed the need to adopt green economic stimulus policies in the aftermath of the COVID-19 pandemic, in line with the United Nations Sustainable Development Goals and the Paris Agreement on Climate Change. This paper provides an integrated framework to design an economic recovery strategy aligned with sustainability objectives through a multi-criterion, multi-stakeholder lens. The aim is to enable decisions by policy makers with the aid of transparent workflows that include expert evidence that is based on quantitative open-source modeling, and qualitative input by diverse social actors in a participatory approach. The paper employs an energy systems model and an economic input-output model to provide quantitative evidence and design a multi-criteria decision process that engages stakeholders from government, enterprises, and civil society. As a case study, the paper studies 13 green recovery measures that are relevant for Cyprus and assesses their appropriateness for criteria related to environmental sustainability, socioeconomic and job impact, and climate resilience. The results highlight trade-offs between immediate and long-run effects, between economic and environmental objectives, and between expert evidence and societal priorities. Importantly, the paper finds that a “return-to-normal” economic stimulus is not only environmentally unsustainable, but also economically inferior to most green recovery schemes.
