If you haven't yet heard, today the federal government issued a new rule to make sure that our nation's "heavy duty vehicles" (big rigs, delivery vans, garbage trucks, and the like) go almost 40 percent farther on a gallon of fuel. This new rule will reduce global warming emissions by 1.1 billion tons and oil use by 2 billion barrels over the lifetime of the program. This is the single most comprehensive set of fuel economy and global warming pollution standards for heavy duty vehicles ever put in place, and the United States now has the strongest truck fuel economy standards in the world.
