Lists of Green Cars. If you're looking to reduce your carbon footprint and overall impact on the environment, then these are the autombiles for you! With fuel prices on the rise, and the environment in need of our help, going green is as popular as ever. These lists take into account all aspects of whether or not a vehicle is truly "green", including manufacturing, materials used, and how much pollution it creates when on the road. Don't just be trendy, do the research! The Toyota Prius is not currently the greenest car on the road. These lists are the place to start. I'm a bit of an ACEE junkie (American Council for an Energy-Efficient Economy), and most of these lists of autos are based on their studies.
