Aberdeen City Council will continue with a study to develop a low emissions zone in the city, after approval from councillors.
Members of the urgent business committee agreed to push ahead with the feasibility study when they met yesterday.
Earlier this year First Minister Nicola Sturgeon revealed the Scottish Government’s pledge to establish a zone in Aberdeen by 2020.
The zones aim to deter high-emission vehicles from areas popular with pedestrians with charges and penalties for driers are among the ways this can be achieved.
Streets that could be affected by the scheme include Wellington Road, Union Street and Market Street.
The scheme could cost around £10 million to £20m, based on studies elsewhere in the UK.
An air quality model is currently being carried out by SEPA in the city.
The data – which reveals a significant reduction in the number of cars on most major city streets between 2012 and 2017 – is now being looked at to see which vehicle types can be singled out as polluters.
