Why is fuel economy important?
Vehicles with lower economy create more carbon dioxide – the most important human-made greenhouse gas – than vehicles with higher fuel economy. Every gallon of gasoline your vehicle burns puts 20 pounds of carbon dioxide into the atmosphere.
One of the most important things you can do to reduce your contribution to global warming is to buy a vehicle with higher fuel economy. Choosing a vehicle that gets 25 rather than 20 miles to the gallon will prevent 10 tons of carbon dioxide over the lifetime of your vehicle. Choosing the most fuel-efficient vehicle in a class could save you more than $1,500 in costs and prevent over 15 tons of greenhouse gas pollution over the lifetime of your vehicle.
