What the Advanced Clean Truck Rule Will Do for Oregon

The adoption of the Advanced Clean Trucks (ACT) and Heavy-Duty Omnibus (HDO) rules in Oregon is projected to significantly reduce toxic air pollutants and greenhouse gas emissions from medium- and heavy-duty (M/HD) vehicles. By 2050, these regulations are expected to reduce NOx emissions by nearly 90% and PM2.5 by over 80%, preventing approximately 156 premature deaths and 118 hospital visits. Economically, the shift is projected to generate $21.2 billion in cumulative net societal benefits by 2050, with electric truck operators seeing an estimated $60,000 in net lifetime savings per vehicle by 2040 due to lower fuel and maintenance costs.

• Medium- and heavy-duty (M/HD) vehicles have a disproportionate impact on Oregon's pollution; while they make up only about 10% of vehicles on the road, they are responsible for 42% of global warming emissions, 70% of NOx, and 64% of PM2.5 from all on-road vehicles.
• The adoption of the ACT and HDO rules will increase the share of zero-emissions M/HD vehicle sales in Oregon from less than 1% today to nearly 30% by 2030 and nearly 60% by 2035, which will eliminate almost 50 million metric tons of carbon dioxide cumulatively through 2050.
• Public health improvements by 2050 include a nearly 90% reduction in NOx and over 80% reduction in PM2.5 emissions from M/HD vehicles, leading to 156 fewer premature deaths, 118 fewer hospital visits, and over 83,000 avoided minor sicknesses, totaling more than $1.8 billion in health care savings.
• The transition is expected to provide $21.2 billion in cumulative net societal benefits by 2050 and $2.1 billion in annual net societal benefits. Individual electric truck operators are projected to save $60,000 in net lifetime savings per vehicle by 2040.
