We recognize the efforts of our suppliers to improve access and opportunities for small and minority- and women-owned businesses. In April 2015, the Postal Service recognized 16 suppliers for outstanding performance in supplier performance, excellence, innovation, diversity and sustainability. Among other prestigious awards, we honored Hollingsworth Logistics Group with the Supplier Diversity Award and Southern Mail Service Inc. with the Supplier Sustainability Excellence Award. This latter award category recognizes excellence in implementing environmentally preferred business practices that help USPS achieve sustainability goals and reduce its carbon footprint. Southern Mail Service partnered with USPS for a compressed natural gas vehicle pilot that saved approximately $1.57 per gallon of diesel fuel.
