Professor Johan C. I. Kuylenstierna
Reader / Research Leader



Johan is a Research Leader at SEI, a member of SEI’s Global Research Committee, and Professor at the University of York, UK, where he has worked since 1986. He is a member of the Scientific Advisory Panel (SAP) of the Climate and Clean Air Coalition (CCAC) and of the York Civic Trust Environment Committee. Key areas of interest include the integration of strategies to address climate change and air quality, in particular to reduce Short-Lived Climate Pollutants (SLCPs). He is part of a team developing and applying a strategy support tool, LEAP-IBC, used by many national and local governments for air pollution and climate change mitigation strategies, and has contributed to assessing impacts of air pollution on health.

He has supported regional air pollution agreements: the UN ECE Convention on Long-Range Transboundary Air Pollution, regional cooperation in South Asia (the Malé Declaration) and southern Africa (APINA). He coordinated a UNEP/WMO integrated assessment on Black Carbon and Tropospheric Ozone and is an author of the other CCAC and UNEP assessments, including GEO4 and GEO5, regional SLCP assessments in Latin America, Asia and Africa, and also the Global Methane Assessment (GMA).

Johan also engages with the private sector to quantify value chain air pollutant emissions, engaging with the World Economic Forum coordinated ‘Alliance for Clean Air’, and he supported the development of a practical guide to quantify and reduce air pollution from businesses. He has been supporting City of York Council in their development of the York Climate Change Strategy and its implementation.
