Advancements In Clean Diesel Technology And Fuel To Continue Major Reductions In Black Carbon Emissions

New Clean Diesel Truck Engines Have Reduced Particulate Emissions - Including Black Carbon - by 98 Percent

WASHINGTON, Jan. 16, 2013 /PRNewswire-USNewswire/ -- Advancements in clean diesel technology will continue to deliver major reductions in black carbon (soot) emissions in both the U.S. and worldwide, Allen Schaeffer, the Executive Director of the Diesel Technology Forum said today.

Schaeffer highlighted the advancements in diesel technology and fuel in response to the new study published in The Journal of Geophysical Research-Atmospheres that stated black carbon emissions are the second most important contributor to global warming, behind carbon dioxide.  The study evaluated climate forcing of black carbon during the industrial era (i.e. 1750 to 2000). 

"While there continues to be ongoing debate about the role of black carbon on the earth's climate, the diesel industry continues to move forward and produce more fuel efficient diesel engines that have both lower emissions of carbon dioxide (CO2) and near-zero levels of emissions of particulate (soot)," Schaeffer said. 

Diesel Truck and Buses Have Reduced NOx Emissions by 99% And Particulate Emissions by 98%"A complete transformation of diesel technology in the U.S. has taken place in the last decade that has virtually eliminated particulate (soot) emissions from new diesel engines across the board. For example, emissions from heavy-duty diesel trucks and buses have been reduced by 99 percent for nitrogen oxides (NOx) - an ozone precursor - and 98 percent for particulate emissions, which include black carbon.  Today, clean diesel technology with near zero emissions is standard equipment in nearly all off‐road diesel vehicles and equipment such as construction equipment, agricultural vehicles, stationary generators, locomotives and marine vehicles.

"Because of the investments in new technology it now takes 60 of today's technology trucks to emit the same level of PM (soot) emissions as a single truck built in 1988."
