"Automakers are putting a new emphasis on cars and trucks that excel at cutting carbon-dioxide emissions to reduce global warming." "In the past, CO2 was treated as just a component of the noxious vapors spewing from tailpipes. Now, it's being singled out." "It's not just good public relations. Since the Supreme Court ruled earlier this year that the EPA can regulate greenhouse gases, General Motors, Ford Motor and Chrysler have joined the U.S. Climate Action Partnership, a coalition of corporate executives calling for CO2 restrictions. California, the nation's biggest auto market, is expected to adopt its own tougher carbon restrictions by December." http://www.usatoday.com/money/autos/enviro...nterstitialskip
