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 Regions 9 and 10, the newest, cleanest, near-zero-emissions diesel truck technologies now make up only 36.7 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 lowest 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. “Even the slow progress in Regions 9 and 10 reinforces the vital societal benefits being delivered today by the new generation of diesel. No technology is as vitally important to achieving current and future goals as advanced technology diesel engines.”
Among the West Coast states in Region 9 & 10, which includes California, Washington and Oregon, the use of newest-generation diesel trucks has delivered substantial emissions reductions and fuel savings. Between 2011 and 2018, the use of the newest, cleanest diesel Class 3-8 trucks has saved 12.3 million tonnes of carbon dioxide (CO2) and eliminated 1.8 million tonnes of nitrogen oxides (NOx). By 2030, the increased use of the cleanest diesel technologies is expected to deliver an additional 120.7 million tonnes of CO2 reductions and eliminate an additional 5.5 million tonnes of NOx collectively in these three West Coast states.
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 NOx emissions of no more than 0.20 grams per brake horsepower hour (g/BHP-hr). This is in addition to PM emissions levels of no more than 0.01 g/BHP-hr.
National Analysis
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 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%).
