Every gallon of gasoline burned produces 19 pounds of carbon dioxide. That’s 25 pounds when you count the energy that went into making and distributing it. So every gallon really does make a difference. We also live in an impatient world so we know that it can be difficult to make any changes, but driving the speed limit actually saves gas. So does maintaining a constant speed. Rapid acceleration and breaking can decrease fuel economy by 33 percent. Also, try combined trips and avoid rush hour because of the stop & go nature of traffic. Flooring the gas pedal can waste gas so drive less aggressively.
