Increasing fuel efficiency standards for new passenger vehicles to an average of 39 miles per gallon over the next decade would save 51 billion barrels of oil over the next 50 years -- more than 15 times the likely yield from the Arctic Refuge.

Simply upgrading the quality of replacement tires to match that of tires that come as standard equipment on new cars would save 5.4 billion barrels of oil over the next 50 years -- 70 percent more than the total amount of oil likely to be recovered from the Arctic Refuge over the same period.

It is estimated that all the recoverable oil in the ANWR would never satisfy more than 4 percent of the U.S. demand at any given time. If the refuge were America's only source of oil, the total amount available in the ANWR would sustain the U.S. for less than 6 months.

Stop Transportation Excesses
      Transportation accounts for 65% of U.S. oil consumption and is the predominant source of air pollution. New transportation technologies are intended to improve the efficiency and emissions of vehicles using petroleum-based fuels, provide cleaner-burning alternative fuels, and reduce the quantity of miles individual vehicles travel on our roads and highways. Do you really want a vehicle that only gets 12 MPG? There are alternatives.
