When fossil fuels are burned, carbon dioxide is released. Cars release carbon dioxide, which is a major contributor to the greenhouse effect. For every gallon of gasoline consumed by an automobile, about 19 pounds of carbon dioxide are emitted. For an automobile with a gasoline tank that holds 12 - 15 gallons, each tank of gas consumed results in the release of about 220 to 300 pounds of carbon dioxide into the atmosphere!
