Greening Cars

California car manufacturers will have to start retooling their models to meet the state’s vehicle emissions standards by 2016. Host Steve Curwood talks with two researchers who are looking at this debate from opposite sides. Louise Bedsworth represents the Union of Concerned Scientists, and says there are cheap ways to cut tailpipe emissions by as much as 40 percent, while Tom Austin, consultant to the Alliance for Automobile Manufacturers, says outfitting cars with more efficient technology is ultimately up to the consumer.
