The transportation sector consumes 70% of the petroleum that the United States uses for fuel, which leads one to study transportation to identify significant opportunity to save energy. Every one-cent increase in the price of a gallon of gas costs the United States Postal Service $8 million per year for their 200,000 vehicle fleet. To red uce American dependence on fossil fuels, the carbon footprint left by vehicular fleets should be evaluated. This paper reports on the current state of fuel efficiency and fleet efficiency in the United States, including government, municipal and large commercial sectors. It will also discuss opportunities in behavior modification to improve fleet efficiency. Case studies will be presented showing evidence of best practices currently implemented. By studying transportation fleets and educating transportation fleet managers of viable alternatives to improve fleet efficiency, we can save significant amounts of fuel and reduce our carbon footprint. This analysis will demonstrate that transportation efficiency is economically feasible for a wide variety of public and private entities and a benefit to the environment.
