Gregor Kiesewetter

Gregor Kiesewetter is a research scholar in the Pollution Management research group (previously Air Quality and

Greenhouse Gases Program) at the International Institute for Applied Systems Analysis (IIASA) in Laxenburg, Austria, where he has worked since 2011. With a background in atmospheric physics, he has been leading the development of the ambient air pollution and related health impact calculations in IIASA’s global Greenhouse Gas‐Air Pollution Interactions and Synergies (GAINS) model. His research interests include assessing the contributions of local versus remote sources to urban pollution with a focus on PM2.5, designing mitigation scenarios across various spatial scales from local to global, understanding distributional aspects of pollution and inequality, and quantifying the health co‐benefits of climate change mitigation action. Since 2018, he has been involved in the Lancet Countdown on Health and Climate Change where he has been responsible for the quantification of global premature mortality from ambient air pollution by sector and fuel. Among other projects, he has contributed to policy assessments for the European Union’s air quality legislation, regional studies such as the CCAC/UNEP Assessment on Air Pollution in Asia and the Pacific, as well as several World Bank funded projects aiming at pollution management in Vietnam, China, South Asia, and South Africa. Dr. Kiesewetter graduated from the University of Vienna, Austria, with a degree in physics in 2006, and earned his PhD in

environmental physics from the University of Bremen, Germany, in 2011.
