SAN FRANCISCO AP _ A federal appeals court sharply rejected the Bush administration’s new pollution standards for most sport utility vehicles, pickup trucks and vans and ordered regulators Thursday to draft a new plan that’s tougher on auto emissions.

The 9th U.S. Circuit Court of Appeals ruled that the National Highway Traffic Safety Administration failed to address why the so-called light trucks are allowed to pollute more than passenger cars and didn’t properly assess greenhouse gas emissions when it set new minimum miles-per-gallon requirements for models in 2008 to 2011.
