One-Third of Registered Trucks Equipped With Clean Diesel Technology, Study Shows

More than one-third of registered medium- and heavy-duty trucks are equipped with clean diesel engines, according to a recent study commissioned by the Diesel Technology Forum.

Clean diesel technology is equipped in 33%, or 2.9 million, of the 8.8 million Classes 3-8 trucks, data compiled by HIS Automotive for DTF show.

“Because more than 95% of all heavy-duty trucks are diesel-powered, it is significant that more than one-third of these trucks are near-zero-emission vehicles,” DTF Executive Director Allen Schaeffer said in a statement.

“These new trucks are so clean that it now takes more than 60 of today’s clean-diesel trucks to equal the emissions from a single 1988 truck,” Schaeffer said.

The Environmental Protection Agency’s 2007-2010 heavy-duty engine and highway diesel fuel sulfur control requirements mandated that beginning with the 2007 model year, all the new on-road diesel trucks were required to meet near-zero-particulate emissions standards.

“Emissions from today’s diesel trucks and buses are near zero thanks to more efficient engines, more effective emissions control technology and the nationwide availability of ultra-low-sulfur diesel fuel,” Schaffer said.

“The new clean-diesel technology has reduced emissions from heavy-duty diesel trucks and buses by 99% for nitrogen oxides and 98% for particulate emissions,” he said.

The study analyzed total registration data on Classes 3-8 trucks from 2007 to 2013 in every state and the District of Columbia.
