Potential Energy Savings and Greenhouse Gas Reductions from Transportation

This project, funded by the Transportation Research Board, will estimate the potential energy savings and greenhouse gas (GHG) reductions that might be realized from transportation. All GHG emissions resulting from transportation will be included. It will review policies and strategies to affect behavior and improve fuel economy for passenger and freight vehicles across all modes. Analysis of alternative fuels will include the full fuel cycle. Scenarios will be developed to illustrate potential savings over a 25-50 year time horizon for the United States. Safety, economic, transportation finance, and environmental trade-offs of energy-saving measures will be included in the analysis. The committee will only address changes in GHG emissions -- not the consequences on climate change of the strategies it examines. Economic consequences will be limited to estimates of direct costs - not including macroeconomic effects. The committee will not recommend any particular strategy; rather it will provide guidance on the energy and GHG reduction benefits of various approaches and pros and cons of implementing such policies. Although the report will describe world-wide transportation demand, the analysis of energy-saving and GHG-reducing strategies will focus on measures the United States can implement.
