Share of clean diesels in U.S. truck fleet nears 40 percent

Updated Aug 21, 2018

According to new research from the Diesel Technology Forum, Class 3-8 trucks model years 2011 and newer made up 36 percent of all commercial trucks on the road at the end of last year – a jump of 6 percent over 2016 and more than 10 percent higher than 2015.

According to the report, only about 21 percent of all commercial trucks Class 3-8 use gasoline, and about 4 percent use “other” fuels. Natural gas accounts for less than 1 percent.

Allen Schaeffer, executive director of the Diesel Technology Forum, says the more than 4.9 million clean diesel trucks now on the road have removed more than 26 million metric tons of nitrogen oxides (NOx) and 59 million metric tons of carbon dioxide (CO2) from the air.
