Gov. Arnold Schwarzenegger, who supports regulating greenhouse gas emissions from automobiles, sent a letter Wednesday to Obama requesting he give California and other states permission to implement tough tailpipe-emission standards.
Schwarzenegger believes Obama's backing would help move America toward global leadership on addressing climate change. If granted, the decision would change a 2007 conclusion by the Bush administration.
The letter details the fact that states do not have authority to impose greenhouse gas standards for new cars, pickup trucks and sport utility vehicles.
According to the Bush administration, such goals can only be met by regulating fuel-efficiency standards, something that falls under the auspices of the federal government.
