David L. Greene is a Research Professor in the Department of Civil and Environmental Engineering and a Senior Fellow of the Howard H. Baker, Jr. Center for Public Policy.
In 2013 he retired from Oak Ridge National Laboratory as a Corporate Fellow. He is an author of more than 275 professional publications on transportation and energy issues, including 100 articles in peer-reviewed journals and 12 National Research Council reports.
The 2012 recipient of the Transportation Research Board’s Roy W. Crum Award, he is also an emeritus member of both the Energy and Alternative Fuels Committees of the TRB and a lifetime National Associate of the U.S. National Academies. He received the Society of Automotive Engineers’ Barry D. McNutt Award for Excellence in Automotive Policy Analysis, the Department of Energy’s 2007 Hydrogen R&D Award, DOE 2011 Vehicle Technologies R&D Award, and DOE Distinguished Career Service Award. Greene was recognized by the Intergovernmental Panel on Climate Change for contributing to the IPCC’s receipt of the 2007 Nobel Peace Prize.
Greene’s research interests are focused on energy use in transportation and policies to reduce petroleum consumption and greenhouse gas emissions and achieve a transition to sustainable energy sources. He has published extensively on automotive fuel economy and the Corporate Average Fuel Economy standards and served on all four National Research Council committees that evaluated US fuel economy policy for cars and light trucks.
How technology and policy can accomplish a transition to sustainable energy for transportation is a current focus of his research and modeling. Other research interests include the costs to the US economy of petroleum dependence, the “rebound effect” of increased vehicle use due to increased fuel economy, and modeling consumers’ choices of vehicles and fuels.
