Driving while fighting pollution

A new study suggests laying off the gas pedal and going easy on the brake can cut down on greenhouse gases.

Driving Change, a pilot program based out of Denver, is thought to be the first internet system to track pollution expelled by vehicles.

Participants were able to track their vehicle's carbon footprint online. Results from tracking 160 city vehicles and 240 private cars show that lightly tapping brakes, reducing rapid accelerations and not letting cars idle show an overall emissions decrease of 10 percent.
