Freight Facts and Figures 2013

Table 5-13. Nitrogen Oxides (NO_x) and Particulate Matter (PM-10) Emissions from Single-Unit and Combination Trucks: 2000, 2002, 2005, 2012, 2020, and 2030

Trucks are the largest contributor to freight emissions nationally, producing 2.3 million tons of NO_x in 2012. However, substantial reductions in freight-related NO_x emissions have been made since the U.S. Environmental Protection Agency required the use of ultra-low sulfur diesel (ULSD) fuel in heavy-duty trucks and other diesel-powered highway vehicles beginning in 2006. Between 2006 and 2012, NO_x emissions from single-unit and combination trucks decreased by 55 percent. PM-10 emissions declined by 47 percent over the same period. Truck-related NO_x and PM-10 emissions are projected to further decline by 56 percent and 66 percent, respectively, from 2012 to 2030.
