More than half of US commercial trucks are powered by near-zero emissions advanced diesel technology

The Diesel Technology Forum is breaking the news this week based on IHS Markit data of vehicles in operation as of December 2021

Washington, D.C.—Research shows that for the first time, more than half of all diesel commercial vehicles on the road in the US are advanced diesel technology models. The Diesel Technology Forum (DTF) is breaking the news this week based on IHS Markit data of vehicles in operation as of December 2021 that it commissioned.

The data examines the number of 2010-plus model year diesel trucks operating today. They’re equipped with advanced diesel engines that minimize the production of emissions through efficient combustion, while controlling remaining emissions through advanced technologies including particulate filters, oxidation catalysts, and selective catalytic reduction systems. This enables new diesel trucks to achieve near-zero emissions with increasing fuel efficiency and lower CO2 emissions.

In previous research commissioned for DTF, AutoForecast Solutions found that increasing the numbers of advanced diesel technology trucks on the road will eliminate more than 1.3 billion tonnes of CO2 during this decade.

“This is great news for our environment and economy. It shows that our nation’s truckers and commercial fleet owners are choosing advanced diesel technology, up 4.2 percent over the previous year. That’s because of its solid track record of performance, reliability, and durability. Advanced diesel technology trucks will continue to dominate the market for these reasons, and many more, for years to come,” said DTF Executive Director Allen Schaeffer.

Schaeffer says he’s confident in diesel’s future dominance because those same advanced diesel engines, as well as older diesel engines, are capable of running on low-carbon renewable biofuels. Taken together, these elements make diesel technology part of the solution to reducing greenhouse gas (GHG) emissions. They lower GHG and other emissions 20-80 percent compared to conventional diesel fuel.

Commercial trucks aren’t the only vehicles increasingly using advanced diesel technology. It’s a top choice for school and transit buses, too. The IHS Markit data shows 58 percent of our country’s school buses use advanced diesel technology now, as well as 47 percent of transit buses.

“Even as manufacturers begin to develop zero emission technologies, there is a consensus that diesel technology will continue to dominate the heavy-duty commercial trucking sector for decades to come. The increasing adoption of this newest generation of diesel technology and transition away from older generations of technology is the fastest way to realize our national goals of cleaner air and lower greenhouse gas emissions,” said Schaeffer.
