Table 5-14. Current and Projected Particulate Matter Emissions by Freight Transportation Mode: 2002, 2010, and 2020

As in the case of NOx, trucks are by far the largest contributor to freight emissions nationally, producing two-thirds PM-10 from the freight sector.  Freight emissions of PM-10 are forecast to decline by one-half over the next two decades.  The required use of ULSD fuel in heavy-duty trucks and other diesel-powered highway vehicles will reduce PM emissions and enable the use of advanced pollution control technologies to meet emissions standards.
