Institute for Governance & Sustainable Development

Dr. Gabrielle Dreyfus

Dr. Gabrielle Dreyfus is the Chief Scientist at IGSD, where she collaborates with leading experts and international partners to conduct research, and craft and advance policies to slow global warming through strategies to control short-lived climate pollutants, improve energy efficiency, and protect carbon sinks.

She is an adjunct lecturer at Georgetown University, where she teaches science policy. Dr. Dreyfus is a member of the Montreal Protocol’s Technology and Economic Assessment Panel Foams Technical Options Committee and Energy Efficiency Task Force, as well as a member of the technical review committee of the Global Cooling Prize. In addition to over a dozen scientific and technical publications, Dr. Dreyfus worked as the lead coordinating author on a synthesis report by the International Energy Agency and United Nations Environment Programme on the intersection of energy efficiency and the phasedown of f-gases in the cooling sector. The Cooling Emissions and Policy Synthesis Report, published July 2020, confirmed the significant mitigation available from the dual HFC and improved energy efficiency strategy—the equivalent of up to 260 billion tons of CO2 by 2050, and up to 460 by 2060. Dr. Dreyfus was also lead author of the longer underlying assessment of the report, the Assessment of Climate and Development Benefits of Efficient and Climate-Friendly Cooling.

Dr. Dreyfus served as Chief Scientific Advisor to the Kigali Cooling Efficiency Program (now Clean Cooling Collaborative) housed at the ClimateWorks Foundation, where she co-developed the strategy and led implementation on the policy program for the ground-breaking US$50 million philanthropic collaboration.

Previously she served as the Deputy Director of the U.S. Department of Energy Office of International Climate and Clean Energy, where she led international initiatives and campaigns to strengthen and scale clean energy policy through the Clean Energy Ministerial. She developed expertise in applying science to inform climate, energy, environmental, and international policy through a series of fellowships in the U.S. Senate, National Oceanic, and Atmospheric Administration, and Department of Energy.

Dr. Dreyfus received a doctorate in Geosciences from Princeton University and Sorbonne Université (formerly University of Pierre and Marie Curie) for her research reconstructing climate change history from Antarctic ice core records conducted at the Laboratoire des sciences du climat et de l’environnement and Princeton.
