Transportation vehicle operations in the US contribute 32% of the nation's emissions of carbon dioxide, and 7% of the world's emissions from energy use. Technical options exist to reduce emissions rates, but policies to reduce emissions must recognize the fragmentation of responsibility for key transportation activities among diverse groups of decision makers, and the need to coordinate their decisionmaking. Policies to increase vehicle fuel efficiency affect decisions by vehicle suppliers, transportation service suppliers, and those who demand transportation services. Policies to shift to alternative transportation fuels affect decisions by these decision makers, by fuel suppliers, and possibly by infrastructure developers as well. Long-term increases projected in the demand for transportation services will offset emission reductions from these policies unless service can be delivered by modes with lower emissions, or unless demand growth can be managed as is now occurring in other sectors of the economy. Additional research is needed to determine the most effective demand management strategies. 28 refs., 1 fig., 1 tab.
