Diesel and gasoline prices have stabilized and even fallen, but that’s not stopping the nation’s forward-looking fleets from doing everything they can to save on fuel and improve their sustainability efforts.
After all, fuel is still one of the largest expenses a fleet has, and the sustainability image appeals to shippers, customers and the general public.

For some fleets, that means alternative fuels. For others, it means striving for that 10-mpg goal for a Class 8 truck. At other fleets, it’s all about right-sizing the fleet and vehicles and route optimization, or hauling more freight in the same number of trailers.

We asked fleets, through e-mails, posts on social media, stories on Truckinginfo.com and in our daily Headline News e-newsletter, to fill out a short online survey about their vehicles, alternative fuels and other green initiatives. We also considered other fleets that were clearly leaders in the field. All had to operate at least some heavy-duty trucks, but many have large numbers of medium- and even light-duty vehicles as well.

We wanted to highlight fleets that are ahead of the curve in their sustainability efforts, and we gave extra attention to activities in the past year. We did not include leasing fleets, but want to note that leasing companies such as Ryder and PacLease have been instrumental in helping many fleets make the move into alternative fuels and develop the most fuel-efficient specs.

Our goal was to incorporate a wide variety of sizes, types and vocations of fleets, as well as a broad spectrum of “green” strategies. Sizes range from the for-hire mega-fleet Schneider down to the 45-truck private fleet Performance Transportation LLC. Green facilities also played into the results this year, with recycling programs, energy-efficient lighting, solar panels and more.

HDT honored many of this year’s winners in a ceremony during the Green Fleet Conference last month in Schaumburg, Ill.

In alphabetical order, here are HDT’s Top 50 Green Fleets for 2014.

AmeriPride Services

Minnetonka, Minn.

Private fleet

With a 2,000-plus fleet with vehicles of all sizes covering the U.S. and Canada, the textile rental company says there’s no single alternative fuel that fits all situations. It has tested CNG, propane, hybrid electric, biodiesel, hydraulic hybrid and pure electric vehicles and will be buying all of the tested technologies over the next three to five years. Idle reduction programming for diesel vehicles newer than 2008 and idle control devices for gasoline-powered step vans newer than 2011 have saved more than $2 million in excess idling over the past three years. Trailer skirting has been added to all trailers that travel over 50 miles per trip, and double-decker trailers increase shuttle payloads by 60%.


St. Louis, Mo.

Private fleet

Anheuser-Busch last year laid out a five-year path to sustainability, and its private fleet, which has more than 600 vehicles, is part of that plan. By 2017, its goal is to reduce greenhouse gas emissions in logistics operations globally by 15% per hectoliter from a 2013 baseline. It’s collaborating with partners to share fleets in the U.S. and Brazil to reduce empty mileage on return trips and take advantage of complementary supply chains and customer footprints. The company also recently announced a partnership with Ryder and J.B. Hunt transport to replace its 66-tractor diesel fleet in Houston with CNG-powered vehicles. The vehicles are expected to be deployed starting this month, and the fleet will be fully operational next year.

Carbon Express

Wharton, N.J.

For-hire carrier

Last month, this 50-truck liquid tank truck company received an award from the New Jersey Business and Industry Association for Environmental Excellence. Lightweight specs, including running daycabs even over the road, allows Carbon Express to haul 5,000 to 7,000 more pounds of product than the competition, which means fewer truckloads being shipped but customers receiving the same amount of product. It also means no fuel wasted idling overnight. In 2013, Carbon started buying Volvo trucks with a 6x2 axle configuration to further reduce weight and increase fuel mileage. Some liquid bulk tank trailers have lift axles that automatically lift when the tank is empty, for a 1.5- to 2-mpg savings.

Cargo Transporters

Claremont, N.C.

The city fleet has more than 900 heavy, light and medium-duty vehicles. Columbus’ Green Fleet Action Plan is designed to reduce the city’s carbon footprint and save taxpayers close to $2 million per year by 2020. The City expects to be displacing over 1.1 million gallons of diesel annually by 2020. It’s doing this primarily through CNG, along with biodiesel use. The goal is for 80% of each budget year to go to “green” purchases. Columbus exceeded this goal in 2013, and as of early August this year, 29 out of the 32 purchased have been green and 25 have been CNG. The city recently opened one of the largest CNG public access stations in the Midwest.

City of Santa Ana

Santa Ana, Calif.

Government/utility fleet

A five-year Green Fleet Strategic Plan was launched last year by the fleet department, aiming to create a fleet that is 75 to 80% alternative energy sources. In the past two years, the more than $1.5 million in grant funding has helped the fleet buy heavy-duty propane and CNG trucks and diesel emissions control systems. Using grant funding, the City Yard was able to install fueling facilities for hydrogen and CNG vehicles. Since 2010, the fleet has been streamlined and cut from 950 vehicles to 651.

Walmart generated some of the biggest buzz of this year’s Mid-America Trucking Show with its futuristic concept truck, the Wal-Mart Advanced Vehicle Experience, or WAVE. The rig demonstrates materials and electro-mechanical systems that could help the giant retailer get further toward its goal of doubling fleet efficiency by 2015 (compared to 2005). The futuristically styled tractor was powered by a microturbine-electric hybrid drive system and pulled a trailer made of lightweight carbon fiber. Walmart has road-tested a number of prototype technologies, including hybrid assist, wheel-end hybrid assist, full propulsion hybrid, LNG and CNG.

Waste Management has grown its compressed natural gas refuse truck fleet from 400 in 2007 to more than 3,200 CNG trucks in North America today. Looking to the future, 90% of its corporate-wide truck purchases will be natural gas vehicles, an investment surpassing $1 billion. Some of that natural gas is gleaned from landfills. By the end of this year, it will also have 75 natural gas fueling stations throughout North America, 47 of which will allow third-party access.
