More Newest-Generation Diesel Class 3-8 Trucks on U.S. Roads Nationwide, Delivering Significant Emissions Reductions and Fuel Savings
October 30, 2019 (WASHINGTON) – In the states that comprise EPA Region 6, the newest, cleanest, near-zero-emissions diesel truck technologies now make up 48.9 percent of the diesel-powered commercial vehicles on U.S. roads – from box delivery trucks to 18-wheelers, according to the Diesel Technology Forum’s analysis of 2018-2019 U.S. vehicles in operation data (Class 3-8) provided by IHS Markit. This region has the highest adoption rate of new-generation diesel vehicles in the nation.
“As more of America’s commercial trucks rely on the newest, cleanest diesel technologies, greater air quality and fuel savings benefits are being realized by communities across the country,” said Allen Schaeffer, executive director of the Diesel Technology Forum. “As we look to the future where new fuels and technologies may come more into focus, we can’t hit the pause button on progress today. These new findings reinforce the importance of the new generation of diesel in delivering vital societal benefits today in the here-and-now. No technology is as vitally important to achieving current and future goals as advanced technology diesel engines.”
Texas, one of the Region 6 states, ranks first in the nation for the greatest total number of newest-generation diesel trucks. Oklahoma, another Region 6 state, has the second-highest percentage of newest-generation diesel trucks, with 56 percent of the state’s diesel fleet using the newest, cleanest diesel technologies. Oklahoma also experienced the highest growth rates, with the diesel fleet growing 13 percent between Dec. 2017 and July 2019.
Beginning in 2011, all new heavy-duty trucks have been equipped with selective catalytic reduction (SCR) and particulate control technologies. These combine to achieve stringent new U.S. Environmental Protection Agency (EPA) emissions requirements for nitrogen oxide (NOx) emissions of no more than 0.20 grams per brake horsepower hour (g/BHP-hr). This is in addition to particulate matter (PM) emissions levels of no more than 0.01 g/BHP-hr.
Nationwide, the newest, cleanest, near-zero-emissions diesel truck technologies now make up 43 percent of the nearly 11 million diesel-powered commercial vehicles on U.S. roads, according to the Diesel Technology Forum’s analysis of 2018-2019 U.S. vehicles in operation data (Class 3-8) provided by IHS Markit.
Since 2010, these newest-generation diesel trucks have eliminated 126 million tonnes of carbon dioxide (CO2), 18 million tonnes of NOx, and saved 12.4 billion gallons of diesel and 296 million barrels of crude oil. Put into context, the emissions and fuel savings attributable to new-generation diesel engines in commercial trucks equates to making 26 million cars all-electric, achieving carbon sequestration in a forest roughly the size of Texas, or creating a 27,000-turbine wind farm on land four times the size of Washington, D.C.
Since 2007, technologies developed to meet near-zero standards for PM eliminated 1 million tonnes of PM, which is equivalent to eliminating the PM emissions from all U.S. cars for 33 years.
By 2030, thanks to the continued increase of newest-generation diesel-powered vehicles, these savings are projected to grow to 1.3 billion tonnes of CO2, 73 million tonnes of NOx, 4 million tonnes of PM, 130 billion gallons of diesel and 33.1 billion barrels of crude oil.
According to the same dataset from IHS Markit, a total of 17 states are at or above the national average for the percentage of clean diesel Class 3-8 commercial vehicles (All US: 43%), and 15 states are growing their clean diesel fleets faster than the national average (All US: 6.8%).
