How Green Is Your Car?

Thinking of buying a new car? Visit Yahoo! Autos Green Center to check your pick's environmental impact first. The site's "Green Rating" ranks each car from 1 to 100 on factors such as tailpipe pollution, greenhouse gas emissions, and fuel economy; the higher the score, the "greener" the car. Other interactive features allow users to compare gas mileage and locate alternative fuel stations in their area. That's something to yahoo about.
