Walmart drivers deliver more than products to our stores. They ensure that our mission of Every Day Low Prices reaches our customers and communities. Our private fleet of over 7,200 drivers, 6,000 tractors, 53,500 trailers and 5,600 refrigerated trailers traveled approximately 700 million miles last year, and did it as one of America’s safest private fleets. Our goal is to create trucking advancements that deliver more savings to our customers and cleaner air. We’re aiming to make our fleet 100% more energy efficient by 2015. This includes keeping 26 billion pounds of carbon dioxide out of the air between now and 2020.
