Sustainability Performance The Postal Service is committed to reporting the results of our sustainability efforts every year. Our targets are in conjunction with those established through Executive Order in terms of reductions and base years for comparison. In FY2014, we achieved the following: Total greenhouse gas emissions were down 12 percent. Facility energy use was down 33 percent. Water usage was down 41 percent. Consumables purchased were reduced by 41 percent. Waste diversion from landfill was 40 percent. Transportation fuel use increased 8.5 percent. The first four results met or exceeded our targets. The diversion from landfill to recycling is below target, but we are already implementing a plan to drive this diversion to over 90 percent. The continued increase in fuel use is due to an aging fleet of vehicles that must be replaced.
