All efforts are having an impact. UNFI saved 98,519 gallons of diesel fuel through increased fuel efficiency in 2013. According to Altemus, UNFI generally maintains a 7 year life cycle on tractors and an 8 year life cycle on its trailers and is expecting that nearly every distribution location will have exposure to Precedent technology before years' end so those efficiency numbers should only get better. Walking the Walk While UNFI is consciously making sustainable improvements to its fleet, the company's investments in green initiatives go far deeper and are company-wide. In 2010, the company pledged to reduce its carbon emissions by 5 percent within 5 years and it is well on its way. The company's 2013 Sustainability Report entitled 'Cultivating Change' is more than impressive. UNFI has built multiple LEED® (Leadership in Energy and Environmental Design) certified buildings and is pursuing LEED certification on several new projects.
