Gov. Jerry Brown said Friday that he will push next year to set even higher greenhouse gas emission reduction targets for California, where the nation's toughest carbon standards already are causing anxiety among businesses and consumers.

"We want to set in the coming year a goal for 2030 which is far more stringent, and it'll be far more difficult," Brown said in a telephone interview with The Associated Press.

California's current carbon emissions law, signed in 2006, sets goals through 2020. If Brown wins re-election in November, the Democratic governor said he would bring together environmentalists, oil companies and transportation companies to accomplish the "challenge and opportunity."
