Newest Technology Clean Diesel Trucks Now Make Up 27 Percent of New Jersey's Commercial Vehicle Fleet, Saving 86 Million Gallons of Fuel and Slashing Emissions

"Over the last five years, 30 percent of the U.S. trucking fleet adopted the newest clean diesel truck engines and emissions control systems, yielding significant fleet-wide emission reductions and substantial fuel savings," said Allen Schaeffer, Executive Director of the Diesel Technology Forum. "New Jersey's data falls just below the national average. If New Jersey's clean diesel technology adoption rate expands to that of the top state – Indiana, at 51 percent – all of New Jersey's communities would experience cleaner air faster than with any other approach."

According to the Diesel Technology Forum, if clean diesel technology adoption increased to 51 percent, New Jersey could save an additional 25 million gallons of fuel, produce 260,000 fewer tons of greenhouse gas emissions, and eliminate an additional 33,000 tons of NOx.  

New Jersey Ranks #29 for the Adoption of the Latest Clean Diesel Technology

National Data Demonstrates Substantial Benefits of Clean Diesel
As the U.S. trucking fleet transitions to newer clean diesel technologies, communities across the country benefit from immediate fuel savings, lower greenhouse gas emissions and cleaner air. Because diesel overwhelmingly dominates the heavy-duty truck sector and is also the number one power source for medium-duty vehicles, the transition to newer generations of clean diesel technology (2011 and later model years) is significant.

IHS Markit, a global technical marketing research firm, conducted the benefits research on behalf of the Forum. The state rankings data is based on the Diesel Technology Forum's analysis of IHS data on Class 3 through Class 8 diesel trucks, model years 2011 through 2016, operational in all 50 states and the District of Columbia through December 31, 2016.

Key takeaways include:

• On average, 30 percent of the U.S. trucking fleet adopted the newest clean diesel truck engines and emissions control systems.
• Between 2015 and 2016, adoption of clean diesel technologies increased 4.3 percent.
• In total, the latest generation clean diesel engines power almost three million heavy-duty diesel commercial vehicles now on the road.
• Over a five-year period (2011 to 2016), new generation commercial vehicles saved 4.2 billion gallons of diesel fuel, reduced 43 million tonnes of CO₂, and eliminated 21 million tonnes of NOx and 1.2 million tonnes of particulate matter.

The research estimated that significant further benefits would accrue to communities across the country if more of these newer generation clean diesel trucks enter into service.

"These trucks have delivered important benefits in the form of cleaner air, fewer carbon dioxide emissions and dramatic fuel savings," said Schaeffer. "In addition to these substantial societal benefits, a Class 8 tractor-trailer-sized vehicle, powered by the latest-generation clean diesel engine, will save the owner 960 gallons of fuel each year, relative to the previous generation of technology. When these benefits are compounded over the entire clean diesel fleet, the 4.2 billion gallons of fuel saved between 2011 and 2016 is equivalent to almost 40 percent of the strategic petroleum reserve."

How Do Newer Diesels Achieve Near Zero Emission Levels?
NOx emissions on this newest generation of clean diesel trucks are 99 percent lower than previous generations, and produce 98 percent fewer emissions of particulate matter. This results in significant clean air benefits throughout the United States.

To achieve these new levels of emissions and efficiency performance, the new clean diesel system relies on an efficient engine and optimized combustion system utilizing the most advanced fuel-injection, turbocharging and engine management strategies coupled with advanced emissions controls, and after-treatment technologies including particulate filters and selective catalytic reduction (SCR) systems, all running on ultra-low sulfur diesel fuel.

"Achieving these substantial emissions reductions and efficiency advancements was in part the result of collaboration of the nation's leading truck and engine manufacturers working with the Department of Energy and 21st Century Truck Partnership's 'Super Truck' program," said Schaeffer. "While the intent of this valuable program is to push the margins of research engineering efficiency, it is clear that demand is leading many of these strategies to be integrated into the commercial truck fleet and contributing to real-world emissions reductions and fuel savings."

Beginning in 2011, all heavy-duty diesel trucks sold had to meet NOx emissions of no more than 0.20 grams per brake horse-power hour (g/BHP-hr.). This is in addition to particulate emissions levels of no more than 0.01 grams per brake horse-power hour (g/HP-hr.), established in 2007.
