The state of California passed legislation last week that will mandate the use of ‘Environmental Performance’ labels for all new cars sold in the state. Each vehicle receives a ‘Global Warming’ and ‘Smog’ score ranging from 1-10, 10 being the cleanest. It’s hard to imagine that a person buying a Hummer will be suddenly shocked at its low EP score and rush over to the hybrid dealer, but it may clear things up for the novice environmentalist and weed out potential greenwashers.
And does it rate E-85 engines burning gasoline, because there is very little E-85 available to the public in California?
Does it also rate diesel engine cars using biodiesel blends?
