A council bordering London has banned signs for the Ulez congestion charge from its land.
Essex County Council passed a motion opposing Mayor Sadiq Khan expansion of the scheme to cover all of Greater London next month.
It will ban any new signage on land it owns, reported the BBC.
The expansion of Ulez to outer London boroughs has proved controversial both inside and outside of London.
The Mayor operates a scrappage scheme for non-compliant vehicles, but this does not extend to those living outside London but who may drive into the capital.
Drivers of non-Ulez compliant cars, those which are older and do not meet emissions standards, will be required to pay £12.50 to enter London.
Several areas in the area will be on the border of the zone such as Purfleet, Brentwood and Loughton.
The council’s Cllr Holly Whitbread said: “In Essex, hundreds of residents are attacked by ULEZ, which is a tax without accountability.
“This council recognises the importance of air quality for Essex residents.”
It comes as Mayor Sadiq Khan awaits the outcome of a legal bid by five Tory councils - Harrow, Hillingdon, Bexley and Bromley, and Surrey county council - opposed to the expansion on August 29.
A two-day judicial review hearing concluded at the High Court last week, with a ruling due at the end of the month.
The councils allege that TfL’s consultation on the proposed expansion had been inadequate and confusing. They say Mr Khan acted beyond his powers over the expansion.
However, the Mayor has said he is “working on the basis... that the Ulez will be expanded to all of London towards the end of August.”
Defeat for the five councils would effectively green-light the expanded zone.
