Under the Bush Administration, the EPA refused to allow states to restrict emissions standards, basically saying that they would get around to it on a federal level eventually (obviously not during Bush's presidential term), and it was important to have a single federal standard instead of varying state standards. Obama is quickly changing course on this issue.
President Obama on Monday will direct federal regulators to move swiftly to grant California and 13 other states the right to set strict automobile emissions and fuel efficiency standards.
The presidential orders will require automobile manufacturers to begin producing and selling cars and trucks that get higher mileage than the national standard, and on a faster phase-in schedule.
Great to see Obama already walking the walk.
