NEW YORK – Forbes.com recently ranked the greenest vehicles in the United States, focusing on the companies accounting for 95 percent of all new vehicles sold in 2007. Rankings were based on data from the Environmental Protection Agency (EPA). The fleet-wide "real world" fuel economy performance for each manufacturer for model year 2007 vehicles and the percentage of each automaker's vehicles that meets the EPA's "SmartWay" standard for low carbon and tailpipe emissions were also taken into consideration.
Forbes.com found that more than half of Honda's vehicles sold in the U.S. received the EPA's "SmartWay" stamp of approval. The SmartWay designation is for vehicles that earn a score of 6 or better on each of the Air Pollution and Greenhouse Gas Scores and achieve a combined score of at least 13 when added together. Honda, Toyota and Hyundai Kia all post real-world fuel economy averages of nearly 23 miles per gallon.
