A carbon footprint is defined as:

The total amount of greenhouse gases produced to support human activities, usually expressed in equivalent tons of carbon dioxide (CO2).   When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption and the driving distance:                               (Low MPG = Big FOOTPRINT  &  High MPG = Small FOOTPRINT)

THE BOTTOM LINE:    Driving “GREEN WHEELS” (vehicles with a higher than average MPG rating) will reduce our footprint on the Earth.   ONE CAR AT A TIME, WE CAN TRULY MAKE A DIFFERENCE.
