Streets in London’s Square Mile could go ULEV-only based on results from a forthcoming pilot.

Petrols and diesels have already been banned during peak commuter hours from nine streets in Hackney and Islington

Currently being assessed under a feasibility study, the trial would start in April and ensure that only sub-75g/km ultra-low emission vehicles would be to access the southern section of Moor Lane.

A spokesperson for the City of London Corporation said: “We will carefully consider the results of the pilot scheme and use the outcomes to inform any future proposals for other areas of the Square Mile.”

A public consultation on options for delivering the scheme is due to run this autumn following the feasibility study.

It follows the introduction of a ULEV scheme by Hackney and Islington councils, banning all but the cleanest vehicles from two zones in Shoreditch and Bunhill.

Petrol, diesel and older hybrid vehicles are no longer allowed to enter nine streets during the peak commuter periods of 7am-10am and 4pm-7pm Monday to Friday. Only ultra-low emission vehicles such as electric cars, e-bikes, the newest hybrids and hydrogen vehicles, as well as pedestrians and cyclists, are allowed.
