Table 5-15. Current and Projected Particulate Matter (PM-10) Emissions by Freight Transportation Mode: 2002 and 2020
Trucks produced two-thirds of PM-10 emissions from the freight sector. Freight-related PM-10 emissions are forecast to decline by 50 percent from 2002 to 2020, primarily from a reduction in heavy-duty truck emissions. The required use of ULSD fuel in heavy-duty trucks and other diesel-powered highway vehicles has helped reduce PM emissions and enabled the use of advanced pollution control technologies to meet emissions standards.
