This is no brainer: the new CAFE standards can save the U.S. a lot of oil. How much? That's a more difficult question to answer. Suistanable Business took the calculator out and came up with an impressive result: 1.4 million barrels of oil per day by 2020. Just for sake of comparison, that's about everything that gets imported from Saudi Arabia.

The benefits of reducing fuel consumptions don't stop there. CO2 emissions can be reduced by 230 million tons (metric) - the equivalent of taking out 34 million cars from our roads. Translated into money, this equals savings of $30 billion for citizens if gas prices are $2.25/gal. If gas goes to $4 a gallon, the new standards will save $70 billion.
