Presidential Memorandum
The Energy Independence and Security Act of 2007
President Obama directed the Secretary of Transportation and NHTSA Administrator to publish a final rule by March 30, 2009 increasing fuel economy standards for model year 2011 vehicles, as required by the 2007 Energy Independence and Security Act. The memorandum also instructed consideration of legal, scientific, and preemption issues—including consistency with Massachusetts v. EPA—before finalizing rules for later model years.
