Clean Air, Climate, and Equity


This summer's wildfires were a stark reminder of the links between air quality and a warming planet. Fortunately, many clean energy solutions to address climate change also improve air quality, especially for marginalized communities who are disproportionately harmed by air pollution. Join us on Wednesday, October 27 from 4:30–6:00 p.m. to learn about the major sources of air pollution in Wisconsin, the communities most affected, and the potential for a multisolving approach to address air quality, climate, and equity concerns.

Associate Scientist and Director, Nelson Institute Center for Sustainability and the Global Environment, UW–Madison

Carol Barford is an associate scientist and the director of the Nelson Institute Center for Sustainability and the Global Environment (SAGE). Her work centers on agriculture, food, environmental quality, and related risks.  Before joining SAGE, Barford completed a BA in biology and a MS in ecology at Boston University, and a PhD in environmental engineering at Harvard University.

For her PhD thesis, Barford measured nitrogen stable isotope effects of denitrification and applied the results to track nitrous oxide production in agriculture and wastewater. Barford also held a postdoctoral position in atmospheric chemistry at Harvard, where she studied forest carbon cycling. Her synthesis of biometric and atmospheric methods of measuring forest carbon balance appeared in the journal Science.

Dr. Christopher Tessum is an Assistant Professor in the CEE department at UIUC. His research focuses on modeling air pollution and its health impacts, quantifying inequities in the distribution of those impacts, and proposing and testing solutions. He studies the relationships between emissions, the human activities that cause them, and the resulting health impacts, and he develops modeling capabilities to enable these types of analyses.

Before joining UIUC, Dr. Tessum was a research scientist in the Department of Civil and Environmental Engineering at the University of Washington in Seattle and a postdoctoral researcher in the Department of Bioproducts and Biosystems Engineering at the University of Minnesota. He received a Ph.D. (2014) in Civil, Environmental and Geo- Engineering, and a B.M.E. in Mechanical Engineering (2006), from the University of Minnesota.
