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.

Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? Research takes a long time.

As we confront the enormous challenge of climate change, we should take inspiration from even the most unlikely sources. Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming.
