This chart shows the decreasing trend for annual idling time per truck reported by SmartWay Truck Carriers over the past six years. Truck Carrier Partners have been submitting data via the performance-based SmartWay Truck Carrier Tool since the 2009 reporting year. Taken across all truck classes, reported average hours of idling by Partners' trucks—including both long and short duration idling--were reduced by 33% during this period. (Computed averages of annual hours spent idling by trucks were weighted by fleet size.)

Reducing unnecessary idling lowers fuel consumption, which shrinks operational costs and reduces unhealthy emissions. Partners who are able to reduce idle emissions will achieve higher SmartWay performance rankings. These can be viewed on the SmartWay website at www.epa.gov/smartway/forpartners/performance.htm by shippers and logistics companies that consider environmental performance when they make decisions on what companies to hire to move freight.

SmartWay Truck Carriers have reduced their fleets' average idle hours, including both long and short duration idling, over the last six reporting years. While the reductions have not been uniform across classes, overall, the drop in time spent idling represents significant progress in reducing fuel consumption and emissions.

Truck carriers can reduce hours spent idling by using technologies like auxiliary power units, truck stop electrification, and automatic engine shut-off, as well as through good business practices, like educating drivers to be conscious of the need to turn off the engine if it doesn't serve a purpose to idle.

SmartWay carrier performance rankings, which allow comparisons between carriers on the basis of emissions, are available on the SmartWay website at www.epa.gov/smartway/forpartners/performance.htm.

This graph portrays the total number of trucks operated by SmartWay Truck Carriers in the 2009 reporting year, as compared with the number five years later in the 2014 reporting year, shown by truck class. During the most recent years that Truck Carrier Partners have been submitting data to EPA SmartWay on their operations, the number of trucks has increased overall. In classes 3, 5, 6, and 7, numbers of trucks in SmartWay fleets have approximately doubled, tripled, or quadrupled. While the increase is not quite so dramatic in Class 8B, numbers have still increased by 65% in that class.

The increasing number of trucks in SmartWay Truck Carrier fleets over the past six years, combined with the decreases in hours they spend idling (as shown in the previous two charts), suggests a trend towards reduced emissions and fuel consumption.
