INCORPORATE EFFICIENCY INTO BID SPECIFICATIONS

Including a minimum fuel efficiency standard for each vehicle class in procurement specifications results in only the most fuel-efficient vehicles being purchased. Specifications can also be written so that the smallest and most efficient vehicle in its class is purchased. If life-cycle costing is used, the cost of fuel should be weighted heavily so that fuel savings accrued over the life of the vehicle are sufficiently taken into account.
