California lawsuit could spark real hybrid revolution

California sues EPA over auto emissions ruling

The state of California has sued the EPA in what amounts to a legal demand for the EPA to decide whether or not the state can impose greenhouse gas emissions standards.

"Our future depends on us taking action on global warming right now," Governor Arnold Schwarzenegger said during a news conference. "There's no legal basis for Washington to stand in our way."

With numerous other states prepared to follow California's lead if the EPA gives the state the right to regulate greenhouse gas emission, the decision has huge ramifications for automakers. If California wins hybrid cars, including plug-ins, and electric vehicles will become absolutely essential to automotive success.
