WASHINGTON, Dec. 14, 2012 /PRNewswire-USNewswire/ -- The advancements in clean diesel technology over the past decade in conjunction with new research and development in all modes of diesel engines will play a major role in helping meet the updated Clean Air Act particulate matter (soot) standards announced today by the U.S. Environmental Protection Agency.
"For the last decade, diesel technology has undergone a fundamental transformation to near zero emissions, based on ultra low sulfur diesel fuel, advanced clean-burning engines and new emissions control technology," said Allen Schaeffer, the Executive Director of the Diesel Technology Forum. "These advancements have occurred across the board - from the smallest industrial engine to the increasingly-popular clean diesel cars, commercial trucks, off-road machines and equipment, marine vessels and locomotives.
"The results of these efforts are clear since today, according to EPA, diesel engines account for only a small portion of the national PM emissions inventory – less than six percent."
Modern Diesel Trucks and Buses Have Near Zero Levels of Particulate Emissions
"Just how significant is this accomplishment? Consider that it now takes 60 of today's clean diesel heavy-duty trucks to equal the particulate emissions of one 1988 truck – a 60 to 1 ratio.
Similar Emissions Reductions Underway For Wide Range of Off-Road Engines
"The new generation of clean diesel technology is not only meeting its emissions reduction targets but is also exceeding them," Schaeffer said. "Further contributions will come as more new technology engines and equipment are put into service in the years ahead.
"Just as the EPA's March 2012 Black Carbon Report to Congress stated that new diesel technology will play a major role in helping reduce black carbon emissions by 2030, new diesel technology will play a major role in helping meet the new Clean Air Act standards for soot."

Schaeffer said according to the ARB, diesel particulate emissions from on-road heavy-duty trucks have declined from 7.5 percent in 1990 to 3.8 percent in 2008, with future projections in 2020 for the category to account for only 1.6 percent of all emissions.
