The Partnership for Policy Integrity (PFPI) uses science, legal action, and strategic communications to promote sound energy policy.


Founded in 2010 by Dr. Mary Stuart Booth, an ecologist formerly at the Environmental Working Group (EWG), and Richard Wiles, a co-founder of EWG,  PFPI provides science and legal support so that citizen groups, environmental organizations, and policymakers can better understand energy development impacts on air quality, water quality, ecosystems, and the climate.  Our current work focuses on biomass energy, oil and natural gas drilling, and hydraulic fracturing. 





Dr. Mary S. Booth, PhD.  Director.  Dr. Booth received her Bachelor’s and Masters degrees at the University of Massachusetts, and her doctoral degree in Ecology at Utah State University, focusing on biogeochemistry and plant ecophysiology. She completed postdoctoral fellowships at the Ecosystems Center at the Woods Hole Biological Laboratory and the Earth Institute at Columbia University, working in Alaska and Uganda. Her work in ecology incorporates approaches at several scales, from GIS-based watershed modeling down to soil microbial nutrient cycling. She founded PFPI in 2010, and currently directs PFPI’s science and advocacy work on greenhouse gas, air pollutant, and forest impacts from bioenergy. 


Dusty Horwitt  Senior Counsel. A veteran of energy policy, attorney Horwitt has used his experience in journalism, law and politics to conduct investigative research and advocacy on metal mining, oil and natural gas drilling and hydraulic fracturing. His work helped protect the Grand Canyon and Colorado River from uranium mining and the state of New York from unsafe shale gas drilling.  He has testified on metal mining reform before the U.S. House of Representatives Committee on Natural Resources and the U.S. Senate’s Committee on Energy and Natural Resources.  He has testified on natural gas drilling and hydraulic fracturing before the New York City Council and local government panels in Ohio, Pennsylvania and Virginia.  Horwitt worked at Earthworks and Environmental Working Group as an analyst and senior counsel, as a reporter at the City News Bureau of Chicago and as a congressional staff member.  He graduated from Brown University with a B.A. in History and holds a J.D. from Georgetown University. He is a member of the Virginia State Bar.
