Table 5-14. Current and Future Particulate Matter (PM-10) Emissions by Freight Transportation Mode: 2002, 2010, 2020
Freight emissions of PM-10 are forecast to decline by one-half over the next two decades. 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. New rules requiring the use of ultra low sulfur diesel (ULSD) fuel in heavy-duty trucks and other diesel-powered highway vehicles will reduce emissions of PM and enable the use of advanced pollution control technologies to meet 2007 emissions standards.
