The United States consumes over 10 million barrels of oil per day moving people and goods on roads and rail throughout the country. Surface transportation generates over 23 percent of U.S. anthropogenic greenhouse gas (GHG) emissions. Transportation is the primary cause of U.S. oil dependence with its attendant risks to U.S. energy security. Contributions from this sector will be necessary in any effort to maintain a sustainable and secure economy in the future. There are many opportunities to save oil and reduce GHG emissions under existing federal law and possibly in the next surface transportation reauthorization legislation in the U.S. Congress, while increasing the mobility of people and goods in the
This paper identifies opportunities possible in transportation reauthorization legislation and using existing legislative authority that will save oil and reduce GHG emissions. The strategy focuses on five key elements: vehicles; fuels; vehicle miles traveled (VMT); system efficiency; and construction, maintenance, and other activities of transportation agency operations.
