Exposure to fine particulate matter (PM2.5) is estimated to cause 48,000 deaths in the US annually.

 “Premature deaths from breathing these [PM2.5] particles can occur on the very day that particle levels are high, or up to a month or two afterward. Most premature deaths are from respiratory and cardiovascular causes. Particle pollution does not just make people die a few days earlier than they might otherwise—in many cases these deaths would not have occurred for years if the air were cleaner.”

Diesel trucks: 5% of vehicles, more than 20% of emissions 

“Medium and heavy-duty vehicles, powered by diesel fuel, represent only 5 percent of the vehicles on the road but currently account for more than 20 percent of transportation emissions, as trucks are typically driven much greater distances than cars.” 

– Environmental and Energy Study Institute 

Heavy duty vehicles are the biggest source of diesel pollution

• Diesel trucks, trains and ships are the biggest sources of diesel pollution, and these sources tend to be concentrated in heavily populated areas.

Heavy duty delivery vehicles are also a majority source of, comprising  only 3-6% of US fleet, producing 7 times more nitrous oxides pollution than gas engines.
