"New technology diesel engines, which use ultra-low sulfur diesel fuel, advanced engines and emissions control systems, are near zero emissions for nitrogen oxides, hydrocarbons and particulate matter. In the U.S., EPA indicates that diesel accounts for less than six percent of all particulate matter in the air.
"In the U.S., emissions from heavy-duty diesel trucks and buses have been reduced by 99 percent for nitrogen oxides - an ozone precursor – and 98 percent for particulate emissions.
"Critical to this progress has been ultra-low sulfur diesel fuel which has reduced sulfur emissions by 97 percent – from 500 PM to 15 PM - enabling advanced emissions control devices."
