David Greene is an author of more than 200 publications on transportation and energy issues. His current work includes:

  • Technological and economic potential for fuel economy improvement
  • Impacts of fuel economy policies
  • Potential to mitigate greenhouse gas emissions from transportation
  • Modeling energy transitions for transportation
  • Estimating the costs of oil dependence

He is an emeritus member of both the Energy and Alternative Fuels Committees of the Transportation Research Board and a lifetime National Associate of the 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 and 2011 Vehicle Technologies R&D Award, and was recognized by the Intergovernmental Panel on Climate Change for contributions the IPCC’s receipt of the 2007 Nobel Peace Prize.

Selected Projects:

Modeling the Transition to Electric Drive Vehicles in California (ongoing)

Achieving a transition from petroleum-based transportation to a system powered by electricity or hydrogen poses a unique challenge for public policy. The great energy transitions of the past have been driven by major technological innovations that offered new and better private goods. The goals of a transition to electrically powered vehicles are chiefly public goods: energy security, clean air and avoidance of dangerous climate change. This ongoing research project for the International Council on Clean Transportation is developing a new paradigm for modeling the transition to electric drive vehicles and analyzing the effectiveness of public policies in achieving such a transition.

Sustainably Financing Highway Transportation (2011)

Financing America’s highways has become a crisis at both the state and federal levels. Traditional sources of revenue, especially the motor fuel tax, have been eroded by inflation and recession, and face an even greater challenge from fuel economy standards that propose to more than double vehicle miles of travel (VMT) per gallon of fuel consumed. The Baker Center report, “What’s Greener than a VMT Tax” by s David Greene proposes one practical, cost-effective and sustainable solution: transform the gasoline tax to a highway user fee on all energy used by motor vehicles, indexed to the average energy efficiency of all highway vehicles and to inflation in the costs of highway construction and maintenance. Published in the August 2011 journal, Transportation Research: Environment,  Greene.VMT tax.1-s2.0-S1361920911000630-main this Baker Center research explains how a sustainable source of highway revenue can be efficiently combined with a continuing incentive to improve the energy efficiency of highway vehicles.

Reducing Greenhouse Gas Emissions from US Transportation (2003)

Transportation is the largest source of carbon dioxide emissions in the U.S., emitting more CO2 each year than any other nation’s entire economy except China. In this report, researchers David Greene and colleague Steve Plotkin of Argonne National Laboratory examine the full range of technological and policy options for cost-effectively reducing transportation’s greenhouse gas emissions. The pros and cons, costs and benefits of strategies from fuel economy standards to changing the way we pay for transportation are analyzed. All modes, highway, air, rail and water are included. Three scenarios, depending on the pace of technological change and the strength of the policies adopted were evaluated, producing net reductions in CO2 emissions of 16%, 39% and 65% over 2010 levels by 2050. The research was supported by the Pew Center on Global Climate Change (now the Center for Climate and Energy Solutions) and published in 2003. GreenePEWreport
