Heavy Duty Trucking wants to identify some of the "greenest" fleets in the country for our 2015 Top Green Fleets issue and at the same time learn more about our nation's fleets.

HDT is looking for fleets that have made a commitment to sustainability, alternative fuels, lowering greenhouse gas emissions and increasing fuel economy in innovative ways.

To nominate a fleet (or enter your own), fill out a short online survey with basic information about the fleet, its alternative fuel use and SmartWay participation. There is also room to make additional comments for any “green” projects outside of those.

The program honors fleets that are "green" in many ways — and not just in vehicle emissions, but also those that have committed to greener facilities or recycling programs.

All sizes and types of fleets are encouraged to enter.

One of last year’s Top 50 Green Fleets, AmeriPride Services, used a wide variety of green initiatives that included running CNG, propane, hybrid electric, biodiesel, hydraulic hybrid and pure electric vehicles in its fleet. It also made use of idle reduction programming and trailer skirts.

Another winner, C.R. England, used several technologies to make its trailers more efficient, including IdleAir idle reduction facilities, trailer tails, and wheel covers while also increasing its use of LNG and CNG trucks.

The top green fleets will be featured in the November issue of HDT and on Truckinginfo.com. You can view last year's list here.
