Johan Kuylenstierna
Reader / Research Leader



Johan is a Research Leader at SEI, a member of SEI’s Global Research Committee, and Reader at the University of York, UK, and has worked at SEI since 1989. He is a member of the Scientific Advisory Panel (SAP) of the Climate and Clean Air Coalition (CCAC). Key areas of interest relate to the integration of strategies to address climate change and air quality, in particular associated with strategies to reduce Short-Lived Climate Pollutants (SLCPs). He is part of a team developing an SLCP strategy support tool – LEAP-IBC – being used by many governments to develop national integrated air pollution and climate change mitigation strategies. He also contributed to assessing impacts of air pollution on human health such as on pre-term births and asthma. He coordinated a UNEP/WMO integrated assessment on Black Carbon and Tropospheric Ozone and is an author of the CCAC/UNEP Global Methane Assessment: Benefits and Costs of Mitigating Methane Emissions. He is involved in the implementation of the Global Methane Pledge that follows from momentum built from the Global Methane Assessment. He also has been engaging with the private sector to enable companies to quantify their value chain emissions of air pollutants, engaging with the World Economic Forum coordinated Alliance for Clean Air. As part of this work he has supported the development of a practical guide to quantify and reduce air pollution from businesses.
