Freight transportation is a pillar of the US national economy, but while long-haul trucks account for less than 6% of the vehicle miles traveled over US highways, they account for about 40% of the emissions of air polluting particulate matter and about 55% of nitrogen oxides, the precursor to ozone in the atmosphere, the study said.

A new international study has found that laboratory tests of nitrogen oxide emissions from diesel vehicles significantly underestimate the real-world emissions by as much as 50%. For light-duty vehicles, such as passenger cars, trucks, and vans, the European Union produced nearly 70% of the excess diesel nitrogen oxide emissions.

Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said.

The greater Los Angeles area is a leading emitter of greenhouse gases and is especially affected by harmful diesel emissions. San Bernardino, home to much of Southern California’s trucking and warehouse infrastructure, had 130 bad air days for ozone pollution in 2020.

The study found that 60% of the winter primary hydrocarbon hydroxyl radical reactivity in London is from those diesel-related hydrocarbons; the authors predicted that the longer-chain HCs contribute up to 50 % of the ozone production potential in London. —Dunmore et al. Dunmore et al.

Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and Diesel particle filters for road and off-road vehicles. for 2030 and beyond.
