Wilfried Winiwarter

Senior Research Scholar

Pollution Management Research Group

Energy, Climate, and Environment Program


Wilfried Winiwarter, originally trained as a chemical engineer and working as an atmospheric scientist, joined IIASA in 2003. His interest in systems analysis derives from the overarching challenges of climate research. Working for the IIASA Air Quality and Greenhouse Gases (AIR) program, he has acquired expertise in the biogeochemical cycle of nitrogen, especially on its anthropogenic impacts. That includes describing methods to minimize the release of ammonia or nitrous oxide into the environment, processes that often are connected with agricultural activities.

Prof. Winiwarter started his academic career at Vienna University of Technology, where he obtained a PhD degree and a postdoctoral qualification for academic teaching (''Habilitation''). Partly in parallel with his IIASA affiliation, he was a senior scientist at the Austrian Institute of Technology (AIT), he held a two-year term as Professor for Systems Sciences at the University of Graz, and since October 2017, he has also been Professor of Environmental Chemistry at the Institute of Environmental Engineering, University of Zielona Gora, Poland. In 2019, he received an International Fellowship of the President of the Chinese Academy of Sciences (PIFI) that allows him to spend several weeks both in 2019 and 2020 to work with experts of the Center for Agricultural Resources Research of the CAS in Shijiazhuang, China, on the establishment of ammonia emission limits in the North China Plain.

Having served as a Director of the European Centre of the International Nitrogen Initiative (2013-16), Prof. Winiwarter is the deputy chairman to the Climate and Air Quality Commission of the Austrian Academy of Sciences, and also chairs the scientific advisory board to the ATB (Institut fur Agrartechnik und Biookonomie) in Potsdam, Germany, an institute of the Leibniz association.
