How would you reduce city traffic pollution to zero

[Wallywobbles]

Ok this is entirely hypothetical clearly, but if you were queen of the world how would you go about reducing say London to zero traffic pollution. Money no issue.

So far I'm thinking.
Cars banned (otherwise the rich will always buy their way round it).
All public transport free (maybe temporary)
Electric buses loads of them.
Special paths/lanes for scooters and bikes.

Bit stuck on how you'd get deliveries though. Or do big shops. Clearly lots of thought required on infrastructure changes.

And......

If money is no issue, then I will give everyone a job 10min away from their home. Schools would get a bigger funding with classroom size going down drastically. There would be more schools built. So no need to travel by car or take public transport to school so regularly.

Wider cycle lanes and bulid bike rack on the busses. So that if you get tried or injured you can take the bus hime with your cycle.

Increase police on the roads, to help prevent bikes from being stolen (db got his bike stolen and it was caught on cctv but the image was unclear, so the police said there is nothing more they can as they can't id the perpetrator, but at least they could see how/ when it was stolen).

The best way to stop people from using their car is by taking away the reason they travel by car.

London has the best hope of this due to the fast and reliable public transport system.

When I worked in Central London, no one commuted into work by car because
A) no parking
B) congestion charge
C) congestion
D) public transport is cheaper and faster than driving
E) you can get anywhere in London on public transport with ease
F) there is a culture of cycling, and in some places there are good facilities
In other words, the alternatives are so good and the driving option so unattractive that no one chooses to drive.

If I was going to make London emissions free I would
a) ban taxis from picking up customers other than at taxi ranks, or prebooked customers. This would stop the taxis driving around empty looking for custom (over half of taxis at any one time are driving around empty)
b) vastly expand the network of cycle superhighways, all built to the same standard as the excellent Parliament Square to Tower of London (and beyond) CS3. Ensure engagement with cycling groups to make sure the design is as good as possible. Prevent the LTDA and certain borough councils trying to prevent the schemes because they don't like cyclists.
c) switch all TfL vehicles to electric engines BUT ensure the electricity is generated from renewable sources so you're not just relocating the emissions
d) ban woodburning stoves etc
e) not having anywhere to park bikes securely at home or at work is a major barrier for some people cycling. Ensure that everyone has access to secure bike parking facilities at home and work by a combination of making employers provide spaces to all those who request one, and providing options such as Cyclehoop Bike Hangers on street for those who don't have space to store a bike inside their home.
f) ensure all hire cars are electric only, and make them cheap for local residents - perhaps through a big and subsidised expansion of car clubs so that people have easy access to a vehicle for things like trips to IKEA, DIY house moves, injuries, disability and so on, but don't need to maintain a vehicle of their own.
g) for small and local deliveries, encourage use of cycle couriers and cargo bikes
h) cargo bikes (you can get electric assist ones) available for cheap hire to local residents to make big shops easier
I) deliveries to shops in big lorries are one of the harder ones (are electric lorry engines available?) but perhaps making better use of the rail network overnight to bring containers into stations like Waterloo and / or limiting stores stocking non perishable produce to one or two deliveries per week, not every day.

Wow. Thank you such well thought out answers. I have been using this as an interview question for the Business School where I teach.
