Arguably it should be e.g. £5 per journey, £10 for the most
polluting vehicles (and maybe an even higher figure for e.g. certain
lorries), and £2 for those that are emission free at the tailpipe
(as they are not entirely polluting free in general and there still
needs to be an aspect of congestion charging).* A journey could be
classed as passing through the congestion charge boundary inbound
(with an exception that twice within a very short time was obviously
due to a circuitous journey).
Putting aside the policy issue of charging at all for a moment, that
doesn't work on a topological basis. One car could be driving all day
long while staying inside the emissions zone (remember we are talking
about the N/S circular very soon), whereas another which just happened
to 'live' near the boundary could do half a dozen short trips spread
throughout the day, but nevertheless crossing the boundary.
Unless you set your "very short time" at say 12hrs, which isn't at
all what you meant.

We were talking about the City of London (which is what this thread
started as) and our own made up plans, not the emissions zone as
proposed by the Mayor of London.

It's a bit confusing when people start talking about the congestion
charge, which as far as I know goes to TfL (or its Mayor) rather than
the City of London.

The City is, of course, small enough for this to work.
