Dr. Rebecca K. Saari is an Associate Professor in the Department of Civil and Environmental Engineering at the University of Waterloo. Dr. Saari studies the consequences of climate change and climate policy on human health and environmental inequality. She has 11 years of post-graduate experience in air pollution and air quality modelling at the University of Toronto (2), AECOM (3), Environment and Climate Change Canada (1), and MIT (5). As a professional air quality engineer in Ontario, she completed projects in seven Canadian provinces and territories. Dr. Saari has employed economic models, emissions models, atmospheric chemical transport models, and health response models to assess the costs and co-benefits of climate policy, energy policy, and transportation policy. She has been invited to speak at Harvard University, the University of Toronto, Carleton University, North Carolina State University, and the University of Washington. Her work has been published in Nature Climate Change, and covered in over 16 news outlets including CBC, NBC, and the New York Times. She directly informs policy through invited presentations to state-level policymakers and the U.S. EPA Climate Change Division, and she was cited in an amicus brief submitted by leading climate scientists to the D.C. Circuit Court evaluation of the U.S. Clean Power Plan – the Obama Administration's centrepiece climate policy.
