American Trucking Association

The American Trucking Associations recommends pursuing a federal solution that reduces non-discretionary idling through highway infrastructure improvements and reduces discretionary idling through incentives for new technology.

  • Non-discretionary: idling while stuck in congested traffic
  • Discretionary: idling when drivers idle their engines during their rest period to provide heat or air conditioning for the sleeper compartment, keep the engine warm during cold weather, and provide electrical power for their appliances

These types of idling annually consume an estimated 1.1 billion gallons of diesel fuel. Options currently available to fleets to minimize discretionary idling have the potential to reduce CO2 emissions by an estimated 61.1 million tons over the next ten years – the equivalent of 16 million Americans not driving for a year.
