Pushing the Envelope: "Fuel For Thought" The Postal Service is a leader among federal agencies in sustainability efforts. In 2009, it joined with 20 international postal operators to commit to a 20 percent reduction in carbon emissions by 2020, a goal it has made significant progress toward achieving. A major contributor to greenhouse gas emissions is vehicle emissions. With the largest civilian fleet in the country - more than 213,000 vehicles - the Postal Service has both an enormous opportunity and an enormous challenge in reducing its fuel consumption. So far, the challenges have proved considerable. In its most recent sustainability report for fiscal year 2011, the Postal Service reported that while it met its sustainability goals in six categories, it did not reach its target for reducing petroleum fuel consumption in its own vehicles or in those used by contractors. A growing number of delivery points each year and an aging vehicle fleet have made it difficult for the Postal Service to reduce its petroleum use. Although the Postal Service has worked diligently towards its goal of using alternative fuels, real gains in energy efficiency will be limited until it can overhaul the fleet. Unless the Postal Service's financial situation improves or it finds alternative methods for capital investment, it is not likely to replace its existing fleet of vehicles. This raises questions about the limitations on the Postal Service's ability to reduce its petroleum fuel use and how it can best leverage alternative fuel options. How should the Postal Service achieve its fuel consumption goals when its financial situation is so dire? Should it suspend some of its sustainability efforts while tackling its larger financial and business model challenges? The Sustainability Report indicates that sustainability efforts make financial sense, with savings from reduced fuel use and new revenue from recycling products. Could the savings and revenues be used creatively to fund new energy-savings projects? Read more!
