The award was given to Honda based on the company's 'real world' CO2 emission levels, calculated as an average across the car maker's entire fleet. The study looked at eight of the major car manufacturers to sell cars during 2008 to come up with the overall greenest company.

Honda's fleet apparently produced 14 percent less emissions than the average bench mark set by the rest of the car makers that were studied. Honda has said the addition of the Honda Insight and Honda FCX Clarity contributed to the accolade.
