Toward a Policy Framework for Reduction Greenhouse Gases Emissions from the Transportation Sector

This white paper is concerned with a preliminary investigation of the extent to which transportation climate policy, in the United States, is cohesive and integrated. A second and more important focus of this paper is on proposing directions for a policy framework that could help support cohesiveness and integration. The transportation sector, as responsible for approximately 30 percent of the total greenhouse gases emissions, should embark on a dramatic transformation, if the United States is to steer its economy on a path to climate stabilization. Such transformation will be spearheaded by technology innovation, though societal components will also be essential. Scenario analyses have shown prospective technological pathways that could result in the needed deep emission reductions; the question ahead is about the policy frameworks and specific measures that will be needed to actually attain such reductions.
