Free public transport in London is the only way to save our environment
While short-term measures alert Londoners to air pollution that is already high, our car-centric culture needs to be challenged to permanently tackle air pollution.
Paris has a long-standing reputation as the home of free thinkers and this week the city took the inspired step of making its public transport free of charge during a desperately high spike in air pollution.
In London, our own pollution spike recently led to warnings to keep babies away from traffic-heavy roads and to avoid strenuous exercise. Joggers and vulnerable people are choking in London’s dirty air, which also worsens heart and lung conditions and can cause asthma.
With London also blanketed by a thick layer of brown air
mainly caused by cars, vans and lorries, free public transport is one solution.
The Mayor of London, Sadiq Khan, has already
taken some short-term measures to tackle pollution, such as erecting signs
advising people not to drive and to walk, cycle or take public transport
instead. He also deployed signs telling drivers stopped at traffic lights to
switch off their engines to protect the health of drivers in vehicles behind
them. It is an often overlooked fact that air pollution exposure is often
higher inside cars than it is out on the streets.
While short-term measures alert Londoners to air pollution
that is already high, our car-centric culture needs to be challenged to
permanently tackle air pollution, not just deal with it on 'spike’ days.
The Mayor is introducing an Ultra Low Emission Zone in
London to make the most polluting vehicles pay a charge to drive in the zone.
This is good as far as it goes – but once people pay their daily charge there
is no encouragement to keep journeys short. In fact, quite the reverse: people
may drive as much as possible to get better value from the charge they have
just paid.
Obviously the most effective way to cut pollution is by
slashing the number of car trips made every day. Pollution is measured in grams
per kilometre, so cutting the distances driven will cut emissions whatever the
vehicle.
So there is a good case for making all public transport
free, or at least very affordable, to encourage people to ditch their cars and
get about town in the most sustainable way possible.
When public transport is free or very cheap, there is a
clear financial incentive to taking the bus or tube rather than running a car.
If the Mayor was to follow Paris
and make public transport free – even as a stunt during particularly high
spikes – the potential health benefits of getting Londoners out of cars and
onto buses, trams and tubes, or onto their two feet, would [offset] the lost
revenue.
Roads could still pay their way even with public transport passengers
travelling for free under a road pricing scheme, but this idea has been laying
in the long grass since 1999.
The Rocol (Road Charging Options for London) report suggests
charging by time of day, road driven on, distance travelled and the emissions
of the vehicle being driven to manage demand for road space and keep on top of
pollution and congestion. So it would be very expensive to drive a polluting
car in central London at rush hour whereas in the middle of the night in outer
London with few public transport options it would be much cheaper. The
Federation of Small Businesses, London First, the Royal Town Planning
Institute, the Institute of Civil Engineers and the Royal Academy of
Engineering all support a system of road charging, but no Mayor has yet had the
guts to act on this despite a healthy list of eminent supporters.
Until we take some serious action on transport choice,
whether you think they are gimmicks or not, London will see more pollution spikes
and the worsening health of the people who live there.
