Under the scheme, all motorised vehicles which fail to meet strict emission standards will be banned from 1.2 square mile area of the city centre. Plans for a second city-wide zone excluding non-compliant lorries and buses have bee dropped. The zone is due to be introduced in May 2022 but will only be enforced from June 2024.
