Heavy Duty Trucking announced its second annual Top 50 Green Fleets at the Green Fleet Conference in Schaumburg, Ill., Thursday. A ceremony was held at the conference to honor these fleets for their sustainability efforts.

The Top 50 Green Fleets highlights fleets that are pushing for sustainability and making it a part of their everyday operations, such as improving fuel economy and greenhouse gas emissions, using alternative fuels, building green facilities, etc.

Fleets were asked to fill out a short online survey about their vehicles, alternative fuels and other green initiatives. HDT's editors also considered other fleets that were clearly leaders in the field.

Fleets of all sizes, types and vocations were chosen. There will be a more in-depth article highlighting each of these 50 fleets in the November issue of Heavy Duty Trucking.
