Halvor Lines Inc.
Halvor excels in reducing all eight emissions metrics in EPA’s SmartWay program. The 310 tractors are all powered by 2010-compliant engine technologies or newer. The approximately 800 trailers are either already equipped with CARB-compliant aerodynamically efficient enhancement technologies, or are scheduled for installation. ATDynamics Trailer Tails and SmartTruck trailer under-tray system combined for an average 7.4% improvement in fuel economy. Full synthetic lubricants extend oil drain intervals. A recently completed LED lighting program for facilities, which started in the shop, saves 166,405 kWh/year. During warmer months the majority of fuel at terminal fueling locations contains biodiesel. A Fuel Partnership Bonus Program rewards drivers for fuel-efficient driving habits.Hawaii Electric Light
This utility has the highest percentage of renewable power sources in the country, so it can’t neglect the green aspects of its fleet. All diesel-fueled vehicles run on B20 biodiesel, and some on 100% biodiesel. Out of 65 Class 7-8 trucks, two are also hybrids. Out of 76 Class 3-6, six are hybrids, 59 biodiesel. Count the light vehicles, and altogether there are 26 hybrids, plug-in hybrids and electric vehicles.
H.O. Wolding was the second Wisconsin fleet to join the EPA SmartWay Transport Partnership and continues to receive their highest ratings. A third of the fleet is Freightliner Cascadia models with greatly increased fuel mileage and much lower emissions. Another third of the fleet is being Freightliner Cascadia Evolution models. These tractors are producing over 10% better fuel mileage than the tractors they are replacing. Wolding has promoted biodiesel use since 2004 and has used almost 9 million gallons to date. All tractors have accessory devices to reduce engine idle, and the home terminal has a power rail for drivers to use their shorepower connections.
Since 2011, the company has been updating its tractor fleet, aiming for an average fleet age of 2.5 years. By early 2014 the entire linehaul fleet will consist of 2010 and newer engines. Forty-five percent of the line haul trailer fleet is equipped with aerodynamic belly skirts, providing a 3% improvement in fuel economy. This year Interstate bought more than 300 dry vans with tire inflation systems and trailers skirts to improve fuel economy, and it’s updating its refrigerated trailers with new-technology refrigeration units. Used oil is recycled, and upgrading truck mattresses means fewer thrown away. Initiatives have reduced the use of paper, aerosol cans, brake cleaner and penetrating oil.
A 2012 SmartWay Excellence Award winner, J.B. Hunt’s DeliverGreen sustainability program includes aerodynamic trucks, fuel-efficient drive tires, driver training with simulators, governed top speeds, biodiesel when available and appropriate, reducing empty miles, optimizing routes, idle reduction through driver incentives and auxiliary power units, and converting over-the-road shipments to intermodal.
Part of J.B. Hunt's green strategy involves converting some long-haul freight movement to intermodal.
It says its Cool Transport is an industry-first carbon-neutral transportation service designed with BlueSource LLC, which combines offsetting verified emission reduction credits with existing J.B. Hunt transportation offerings to create carbon-neutral transportation solutions. It offers shippers a carbon calculator on its website.
