Stephen Posner works at the science-policy interface between the design of knowledge systems and enabling conditions for translating ecological economics into action. He is a Sustainability Fellow and Doctoral Candidate at the Gund Institute, University of Vermont, where he develops institutional climate and energy projects, teaches undergraduate courses, and trains student leaders who model and promote environmentally responsible behaviors. He has worked as an independent economic consultant for businesses, NGOs, and governments since 2005. In 2010 he earned an M.S. in Natural Resources and a Certificate of Graduate Study in Ecological Economics from University of Vermont for work on the Genuine Progress Indicator (GPI) in Baltimore City, Baltimore County, and the state of Maryland. Maryland then became the first state in the U.S. to officially report GPI alongside other state statistics. Stephen earned a B.S. in astronomy and physics from Haverford College and studied science education at Stanford University. He lives and plays in Vermont with his wife and two young children.
