The EPA and the U.S. Department of Transportation and Energy recently released two new proposed revamps of the current automotive "window stickers," or fuel economy labels. While the current sticker provides info on city and highway miles per gallon, the new versions will feature environmental impact comparisons across all automotive types, from electric vehicles to conventional gas and diesel cars.New info will include ratings on fuel economy and emissions of greenhouse gas and other air pollutants. One version of the label will actually assign a big fat letter grade to new vehicles' overall fuel efficiency and environmental impact. Consumers are encouraged to to weigh in on which of the labels they prefer, and they can send suggestions to email@example.com. More info on the stickers can be found on the EPA site.
