> An electrical car produces almost as much fine dust particles as an internal combustion engine. This is utter nonsense. Electric vehicles have no direct emissions, including no direct emissions of fine dust. You are confusing this with emissions during production. My point is about emissions at the location of a car's use. > The CO2 and NOx combustion engines produces are not that dangerous to our health. If this was true, there would have been no diesel scandal at all. However, car exhaust is indeed very dangerous to your health, especially if you live next to heavy traffic. https://en.wikipedia.org/wiki/NOx#Health_and_environment_effects https://en.wikipedia.org/wiki/NOx#Health_and_environment_eff... > Soot, mainly produced by heavy diesel engines, is also a dangerous form of polution, but most trucks should have filters for those by now. They should, but reality is different - https://www.spiegel.de/auto/aktuell/abgasskandal-manipulierte-lkw-aus-osteuropa-sorgen-fuer-massive-schaeden-a-1130332.html https://www.spiegel.de/auto/aktuell/abgasskandal-manipuliert... - https://www.unece.org/fileadmin/DAM/trans/doc/2017/wp29/WP.29-172-28e.pdf https://www.unece.org/fileadmin/DAM/trans/doc/2017/wp29/WP.2...

> Electric vehicles have no direct emissions, including no direct emissions of fine dust. QUOTE Traffic related particles can be distinguished into: exhaust traffic related particles, which are emitted as a result of incomplete fuel combustion and lubricant volatilization during the combustion procedure, and nonexhaust traffic related particles, which are either generated from non-exhaust traffic related sources such as brake, tyre, clutch and road surface wear or already exist in the environment as deposited material and become resuspended due to traffic induced turbulence. It is estimated that exhaust and non-exhaust sources contribute almost equally to total traffic-related PM10 emissions. However, as exhaust emissions control become stricter, relative contributions of non-exhaust sources to traffic related emissions will increasingly become more significant.

  > It is estimated that exhaust and non-exhaust sources contribute almost equally to total traffic-related PM10 emissions. However, as exhaust emissions control become stricter, relative contributions of non-exhaust sources to traffic related emissions will increasingly become more significant. So if this "estimate" (i.e. conjecture) is on point, EV produce less than half of the emissions of an ICE car currently (EV have 0 exhaust emissions) and will continue to produce much less even when ICE are somewhat improved (and manufacturers stop defrauding customers). Let's not forget that EV also brake less than ICE cars.

> This is utter nonsense. Electric vehicles have no direct emissions, including no direct emissions of fine dust. Have you ever changed a tire on Tesla because it was worn down? Where do you think the rubber in the old tire went when it was worn down? Emitted into the environment, that’s where.

  The GP is obviously wrong about EVs emitting no fine dust, see my sibling comment, but we're talking about fine dust, i.e. PM10 dust. The study my comment links to notes that only 0.1-10% (depending on conditions) of tire wear meets that criteria, the rest are all more coarse particles.

  Have you measure the gas you burnt between changing those tires. You burnt and put in the air hundreds of times the weight of those tires in gases.

    You’re saying the petrol emissions are worse than other emissions. But the comment I was replying to said there were no other emissions at all.
