London's air quality plan could rely heavily on expanding car clubs, as the cleaner vehicle discount for the Congestion Charge ends this December.
Car clubs offer short-term rentals and could replace 29 private cars per vehicle, reducing emissions and promoting public transport.
Despite benefits, expansion in London faces hurdles like outdated contracts and inconsistent policies across boroughs.
To aid growth, operators seek free permits for electric vehicles and a unified London policy, echoing shared bike and scooter schemes.
