Environmental suit.

Environmental Suit: The state of California sued the U.S. Environmental Protection Agency for denying its first-in-the-nation greenhouse gas limits proposals on cars, trucks and SUVs. The suit challenges the Bush administration's conclusion that states have no business setting emission standards. Other states are also expected to join the lawsuit, which was anticipated after the EPA denied California's request for a waiver Dec. 19 and at least 16 other states are expected to follow California's lead in trying to adopt tougher emission limits. Federal regulators said that the federal government was moving forward with a national solution. Energy legislation already signed by the President will raise fuel economy standards nationwide to an average of 35 miles per gallon by 2020. California wants the auto industry to cut emissions by one-third in new vehicles by 2016 or reach an average of 36.8 mpg.
