Its not just an issue for High Emission vehicles, they often require a
permit which for non-residents can be difficult or time consuming to
obtain at short notice.
This is usually no more a specification check (Paris for example), i.e.
was the car resistered after a certain date and hence conform to Euro
xx emissions standard.

Possibly tag roads withing the zone, in a similar way to weight limits
and other restrictions.
