Hoping to buy an emission-free vehicle in the next few years? Finding one might soon get much tougher.

The proposed change to the state’s Zero Emission Vehicle (ZEV) mandate has stirred up protests from environmentalists and alternative-transportation advocates, who say automakers have little incentive to produce such vehicles unless obligated.

Passenger vehicles emit about 30% of California’s greenhouse gases. For the full story visit http://www.latimes.com/business/la-fi-zev27mar27,1,7041029.story
