Previous work by Gaines and Brodrick (1) compared fuel-cycle air pollutant emissions from long-duration idling of Class 8 trucks to those from various idling-reduction (IR) technologies. That work was written before measurements from model year 2007 trucks with diesel particulate filters (DPFs) were available and before 2010 heavy-duty engine nitrogen oxides (NOx) restrictions were in place. Overall emissions from trucks on the road, including idling emissions, have presumably been reduced significantly since then, but even today, few measurements of idling emissions from trucks meeting 2007 and 2010 emission standards have been published. However, emissions from IR devices have not changed significantly, as small engine standards are unchanged. This paper compares existing information on new truck idling emissions to that on emissions from IR devices. We conclude that use of some idling-reduction devices in place of idling may not actually reduce all air pollutant emissions, although fuel use and carbon dioxide (CO2) emissions are always reduced, and that additional measurements are needed.
