The plan is indeed to get old vehicles off the road.
However, if you have a car that is at least 30 years old in a nearby original and overall good condition (as mine is), you can get some kind of certificate and drive it daily with paying a fixed rate, about 200$/year.
Some small engine cars (2CV, Fiat 500, Fiat 126) are cheaper when paying the regular tax, but their lack of a cat keeps them out of lots of cities.
There are three colours of badges you get to stick behind the windshield, depending on the emissions: red for catless petrol engines and older diesels, yellow for most common rail diesels, green for almost all petrol engines with a cat and all diesel engines with a particle filter.
The certificate counts as a green badge, the best.

The diesel engines with filters are indeed quite clean, the first we got around 2007 still had an exhaust that clean that you'd only have road dust on a cloth wiped through it when we sold it 7 years later.

However, some particles which are way finer still pass the filters, they are said to be dangerous for health - I can not estimate how far this is true.
Another fact is that the direct injection petrol engines emit a very high count of particles, about as much as an older diesel - without having to have a filter.

I would consider adding a turbo to the 30yr old lady, but as far as I know, the standard OM601 does not sport enough piston cooling for that.
So, my dream is finding a 2.5 turbo engine (fitting a series engine would still allow me to get the certificate), but this is nothing of a big priority.
