Founded in 2010, the Partnership for Policy Integrity (PFPI) uses science, legal action, and strategic communications to promote sound energy policy and to help citizens enact science-based policies that protect air, water, ecosystems, and the climate.  Our current work focuses on biomass energy, and oil and gas extraction.



Dr. Mary S.
