The mean dozen

GreenerCars.org recently released its ratings for model year 2011 vehicles. The website, which is part of the American Council for an Energy-Efficient Economy (ACEEE), assigns a Green Score to vehicles based on their fuel efficiency. The organization recognizes the most eco-friendly vehicles in the Greenest Vehicles of 2011 list but also draws attention to poor performers via the Meanest Vehicles for the Environment in 2011 list. While companies want to be featured at the top of the greenest vehicles list, no one wants to be mentioned on the meanest list. (Text: Melissa Hincha-Ownby)
