Taxis could be hit with a £12.50 a day charge to enter the centre of Sheffield as the council look to impose congestion charging across the city.
Sheffield city council believe that a clean air zone will save around 500 lives per year.
The plans will be set out in a consultation in 2019 and will involve residents, businesses, taxi drivers and bus operators.
Buses, coaches and HGV’s face a £50 a day levy to use the inner ring road, with taxis and PHV's facing a £12.50 a day charge. Vans and LGVs will be charged £10, a day, whilst private cars will be exempt.
It is however, believed that the plans cannot proceed without funding from central government, who will make that decision in early 2019.
