  • You havent provided any sources and your claims are nonsense.

    NO2 is a notorious byproduct of diesel engines at 10x the rate of gasoline cars. Dieselgate cars emitted 40x the legal amount. You can’t quite do this, but roughly that means a dieselgate vehicle emitted 400x the NO2 of a gasoline car.

    This math is just nonsense. As you see from the emission standards, the NOx emissions are only slightly higher for diesel cars. Also the 40x number is about US regulations not european ones. Just find some actual sources for this maybe then come back and reply.



  • The difference between the plots is quite significant. Also european NOx emission standards for passenger cars have been unchanged since 2014 for diesel and petrol with diesel emissions only being ~33% higher than petrol which means there would definitely not be such a drastic change just from diesel being phased out. Also dieselgate was actually the “Volkswagen emissions scandal” meaning it affected Volkswagen cars and has therefore basically nothing to do with these stats about Paris because the french VW market share is ~7%. Also the thing is that the color of the roads in 2017 is basically the same for all of the roads, but since 2020 there is a clear shift to the big ring road, meaning there wasnt just a reduction but also a clear shift in where the cars drive. Clearly the pollution is highly localized so this change of banning cars from the inner city significantly improved air conditions for everyone but the people living right next to the big roads.
