Research for the AASHTO Standing Committee on the Environment. Task 90. Transportation Program Responses to Greenhouse Gas (GHG) Reduction Initiatives and Energy Reduction Programs

The prospect of global warming caused by an increase in greenhouse gas (GHG) emissions is a major policy issue. According to the United States Department of Transportation (USDOT), the transportation sector is currently responsible for approximately one-quarter of GHG emissions in the United States and a majority of fuel consumption. Within the Federal-aid highway program states and metropolitan planning organizations (MPOs) have the major decision-making authority for highway construction projects and system operations. This research provides background to understanding the relative GHG reduction and energy efficiency capability of transportation related strategies that States and MPOs can deliver.
