> Indeed, the scale of these emissions is significant. Particulate emissions from tires and brakes, particularly in the PM2.5 and PM10 size ranges, are believed to exceed the mass of tailpipe emissions from modern vehicle fleets, as per a study published in Science of the Total Environment this year.
This simply cannot be true. Tailpipe emissions have more mass than the gasoline that gets burned. A car uses several liters od gasoline per 100km. I am pretty sure no car loses several kilograms of tire or brake matter over 100km.
- Cort3z 3y agoExactly. Not saying this is good news either way, but I can go multiple years on a set of tires, and majority of the mass is still there when I go to charge tires. Perhaps they mean just the mass in the pm2.5-pm10 size spectrum?
- anon84873628 3y agoIndeed, the sentence says "particulate emissions" not gaseous emissions.
- choeger 3y agoThey compare "particulate emissions" to "tailpipe emissions". That's at the least very sloppy writing, at the worst it's intentionally misleading.
- anon84873628 3y agoThey are talking about particles in the PM2.5 and PM10 size range, not the mass of all emissions...
- choeger 3y ago"exceed the mass of tailpipe emissions" - that implies all tailpipe emissions.
- comradesmith 3y agoAren’t a lot of the tailpipe emissions gaseous? Like carbon dioxide, nitrogen oxides, and water?
