Diesel particulate matter is particulate matter. And moder diesels do not emit those because they are captured by the DPF filters... which stands for "DIESEL PARTICULATE FILTER". You need to educate yourself on the subject before you start writing these articles.
Thanks for your note. 1. The article is based on a 2022 study. 2. Most school buses are older models, +10 years. 3. DPF filters have reduced particle emissions, along with the use of low-sulfur diesel, however, they remain a significant source of PM 2.5 particles, posing a health hazard to children. 4. Diesel vehicles alone account for 20% of all NOx and 25% of PM2.5 pollution emitted by vehicles in the US and are a significant source of CO2 emissions -- 464 million metric tons.
