President Obama's initiative to reduce greenhouse gas emissions and boost fuel efficiency in new vehicles would cut costs for consumers and prod carmakers to more quickly roll out greener cars, some analysts say, according to USA Today.

Obama ordered the Transportation Department to boost fuel-efficiency standards for 2011 model cars.

He also told the Environmental Protection Agency to re-examine whether California should be granted a waiver to become the first state to impose greenhouse gas limits on new vehicles, reversing Bush administration policy. The state wants to slash emissions in new cars and light trucks an average 30 percent by 2016. At least a dozen other states joined the petition. Obama didn't order the EPA to grant the waiver, but it's expected to.
