For the third straight year, the Honda GX – a car which runs on compressed natural gas – has been named the “greenest car” for sale in America by the American Council for an Energy-Efficient Economy.

The ACEEE, according to MSN.com is “dedicated to advancing energy efficiency as a means of protecting the environment and strengthening the economy.”

It ranked the top 12 energy efficient vehicles and found that the GX’s “combination of high efficiency and near-zero emissions makes it the cleanest vehicles on the road today, scoring 57 points from ACEEE.”

The three hybrids in the “Clean Dozen” ranked second (Toyota Prius), third (Honda Civic) and 12th (Toyota Camry Hybrid) all scored behind the Honda GX.
