California sued the U.S. Environmental Protection Agency on Tuesday in a desperate attempt to force the approval of a federal decision with new tough standards on automakers to curb global warming.

In 2005, California State issued a law requiring the carmakers to reduce vehicle gas emission with 30% by 2016, which means to cut almost 6.5 million vehicles off California roads, according to the BBC News.

Governor of California, Arnold Schwarzenegger sustained on Tuesday that there is no reason for which the EPA should refuse California’s request.

"There's no legal basis for Washington to stand in our way," Schwarzenegger said at a Capitol news conference, the Reuters reports. Moreover, he added: "We are now ready to implement the nation's cleanest standards for vehicle emissions, and we cannot do that, of course, until the federal government gives us a waiver. Our health and our environment are too important to delay any longer."

He also accused the federal government of denying what tens of millions of people wants if they fail to approve the legislation.

EPA spokesperson Jennifer Wood said that her agency would take a decision by the end of December. "We're less than two months away and clearly California is more interested in getting a good headline than in giving us the time to make a good decision," she said.

California is threatening with suing and suing again fearing that the White House could interfere in the EPA’s decision making the agency to postpone it.

California is not the only state that is willing to change the legislation regarding the massive pollution of the cars and light trucks. If this legal action will have a successful answer, another 14 states in the U.S. will follow California’s example mainly in the Northeast and Pacific Northwest.

The report handed to the EPA contains 16 pages in which the state attorney general‘s office warns that the emissions of car gas is one of the most important source of pollution in California. That is why the state cannot afford to wait any longer for a decision. The gas emission is making the state’s climate change from bad to worse with each year passing.

The auto industry opposes California’s effort because building cars with a new system of gas emission will raise the costs of the vehicles in the U.S., which is definitely not good for the U.S. economy.

The Alliance of Automobile Manufacturers said in a statement that California's lawsuit against the EPA "is not helpful" and that a number of regulations are not the answer to the global warming, Wall Street Journal reports.
