New Generation of Diesel Now Powering 46% of Commercial Trucks in the Northeast, Delivering Key Climate and Clean Air Benefits to Nation’s Trucking Corridor

Region’s new truck adoption rate jumps by six percent over 2019; 30 million tonnes of CO2 removed, 2.6 million fewer tonnes of nitrogen oxides; Massachusetts and New Hampshire among top 10 fastest growing states

June 16, 2021 (WASHINGTON, DC) – New technology diesel vehicles now make up nearly half of all trucks on the road in the Northeastern United States, delivering substantial clean air and climate benefits to the region, says new research and analysis from the Diesel Technology Forum.

Upgrading the oldest trucks on the roads throughout the Northeast with the latest generation diesel trucks has saved nearly 1.5 billion gallons of fuel and removed 30 million tonnes of greenhouse gas emissions along with 2.6 million tonnes of emissions of oxides of nitrogen (NOx) and 150,000 lbs. of fine particle emissions since 2007, according to new research commissioned by the Forum and conducted by AutoForecast Solutions.

“Adoption of the newest-generation diesel technologies in commercial trucks in the Northeast states, particularly in the heaviest applications, has delivered important benefits to many of this region’s most vulnerable communities, particularly those located near ports and warehouse districts. With almost half of all trucks in the Northeast relying on clean diesel technologies, we can see substantial progress toward key state’s clean air and climate goals. Communities realize almost immediate clean air benefits while the fuel savings benefit truck owners and greenhouse gas emission reductions benefit us all,” said Allen Schaeffer, executive director of the Diesel Technology Forum, a not-for-profit educational association.

According to analysis by the Diesel Technology Forum of vehicles in operation data provided by IHS Markit, 46 percent of the region’s commercial vehicles, from small white box delivery trucks on up to the largest 18 wheelers, are now equipped with the newest most advanced diesel technology that achieves near zero emissions and tailpipe emissions standards established by the U.S Environmental Protection Agency. The adoption rate for new technology diesel vehicles in the Northeast is just below the national average of 49 percent. Massachusetts and New Hampshire are among the leading states for the fastest adoption the most new-generation diesel trucks in the nation, as the clean diesel fleet in both states expanded by eight percent since 2019.

 Growth of Diesel in Northeast

As more of the region’s trucking fleet adopts the latest diesel solutions, we can expect further fuel savings and emissions reductions between now and 2030. Research estimates that between 2020 and 2030 further replacement of older diesel trucks with new diesel models will save another 11.5 billion gallons of fuel and eliminate another 105 metric tonnes of greenhouse gas emissions,” noted Schaeffer.

“Alongside tailpipe emission standards, diesel engine and vehicle manufacturers must also meet stringent fuel savings and greenhouse gas reduction requirements. The more stringent of those requirements, the Phase 2 standards kick-in in 2021, are expected to reduce greenhouse gas emissions by over one billion tonnes between 2021 and 2027. Diesel trucks are expected to deliver the overwhelming majority of these future benefits even as planned adoption of alternatives is in place.

“While much attention is focused on emerging zero-emissions technologies, this research show that the adoption of the latest advanced diesel options along with fuel switching to biobased diesel fuels is playing a significant role in eliminating greenhouse gas emissions today in the Northeast.  If all new Class 8 trucks entering the fleet in the Northeast were fueled with either a 20 percent blend of biodiesel or 100 percent biodiesel between now and 2030, the benefits would exceed the planned electrification of the fleet by between a factor of 3 and 17.

“This research reinforces that all available clean technologies are needed to meet the immediate clean air needs and eliminate greenhouse gas emissions today.  Emerging zero-emissions solutions may hold longer term promise, but cleaner diesel trucks and expanding use of ready-to-go biobased diesel fuels can do the most right now to help meet the climate and clean air challenge.”
