HDT’s 2015 Top Green Fleets leave no stone unturned in their quest for better fuel economy, lower emissions, and less impact on the environment.
Lower diesel and gasoline prices may have damped down some of the excitement about natural gas and other alternative fuels, but for many of those on our third annual list, it’s still an important part of their sustainability strategy.
And alternative fuels are hardly the only “green” tactic out there. Fuel economy and reduced greenhouse gas emissions are the primary strategy for many of our honorees, with many reporting 8, 9, even 10 mpg rigs or close to it. Interestingly, some of the fuel-saving tactics that may have landed a fleet on our first Top 50 list aren’t quite as innovative today, as things like trailer skirts, 6x2 axle configurations and automated transmissions have become more common.
In addition, facilities improvements, such as adding solar panels, electric charging for refrigeration units, energy-efficient lighting, etc., were also considered.
We paid more attention this year to what fleets have done in the past year. And we looked harder this year at what fleets are doing to inspire and educate others about how to improve their own sustainability efforts.

Toyota Logistics Services
Long Beach, Calif.
Several years ago, this private car-transport fleet investigated CNG as an alternative fuel, but the large fuel tanks on the back of the cab wouldn’t work with the car haulers. In 2012, with the fuel efficiency increases being made in diesel trucks, it decided clean diesel would become its new “alternative fuel.” Partnering with a fleet analytics company, they replaced the entire fleet of 90 car haulers with 2013 clean diesel equipment. The fleet’s lifecycle was changed from 7 years to 3 years and the lease changed so they could replace less efficient vehicles with more fuel efficient vehicles without penalty. And now that trucks are available with CNG tanks on the side, Toyota recently took delivery of its first CNG pilot model.
This 90-truck for-hire dry van fleet has gone from averaging in the 6’s in fuel economy to 9.2-9.5 mpg over a two-year period, using innovative equipment specs, idle management and SmartWay certified technology. All new power units are SmartWay certified, with complete tractor aero packages, low-rolling-resistance tires, automated manual transmissions, 6x2 axles, no-idle heat / air, adaptive cruise, Intelligent Powertrain Management and additional aero systems such as Flow Below systems. Incoming trailers have PSI tire inflation systems, low-rolling-resistance tires, side skirts and Stemco TrailerTails with auto deploy. Although some fleets shy away from 6x2s because of traction concerns, despite its Northeast location, Transway manages 6x2s through proper tire combinations, electronic suspension controls, locking differentials and driver training.
This year, UPS announced agreements for up to 46 million gallons of renewable fuels over the next three years, making it one of the largest users of renewable diesel in the world. It plans to shift more than 12% of its purchased ground fuel from conventional diesel and gasoline to alternative fuels by the end of 2017. It expects its alternative fuel and technology truck fleet to total more than 7,700 trucks by the end of this year. Since 2013, the parcel delivery service has increased the total number of alternative fuel and advanced technology vehicles by 61%, including more than 1,100 natural gas vehicles (both CNG and LNG) added in 2014 to nearly double its natural gas fleet.
With close to 300 vehicles, this for-hire fleet attains a fleet average for over the road trucks of more than 8 mpg, with some units achieving 10 mpg. Some of the tactics used include speed limiters, low-rolling-resistance tires, a full-time driver trainer focusing on fuel waste, weight-triggered auto lift axles on new trailers, auto lift axles on tractors automatically controlled by weight, 96-inch-wide/13-foot-tall trailers for less resistance, TrailerBlade side skirts, flow-through aerodynamics mudflaps, and automatic tire pressure inflation systems on trailers.
