One of the most visible efforts is the 2.5-acre "green roof" above the USPS Morgan Mail Processing and Distribution Facility in New York City -- the city's largest green roof. In its first year alone, the facility was able to avoid more than $1 million in energy costs and reduce energy consumption by 40 percent. The green roof also reduced pollution runoff between 35 to 75 percent, depending on the season. Plus, the green roof will last approximately 50 years.
Other significant energy savings measures implemented by USPS include energy audits, employee education, and sophisticated energy management and controls systems. The USPS also adopted a number of different software systems to increase the efficiency of its basic business -- sorting and delivering the mail to every address in the US. The IT solutions include software to optimize mail sorting programs and reduce the number of partially filled mail trays; and an "Intelligent Mail" barcode system to improve mail routing and tracking.
The USPS has also brought its suppliers into the process. By 2015, every supplier with a contract worth more than $500,000 will be required to submit sustainability data. The USPS also produces its own annual sustainability report detailing its energy consumption, carbon footprint and greenhouse gas (GHG) emissions, conservation efforts, goals, and progress towards those goals.
