A clean air zone in Leeds will be put in place from 28 September.
Buses, heavy goods vehicles and taxis which fail to meet minimum emissions standards will be charged for entering.
It is part of the council's aim to tackle air pollution by encouraging businesses to switch to cleaner vehicles after finding that parts of the city would likely exceed legal air quality limits.
More than £5.4m in financial support has so far been awarded to help local businesses switch to lower emission vehicles and another £3.1m has been provisionally approved.
Having been forced to delay the introduction of the zone last year due to delays to government systems, I am delighted that we are now able to confirm a go-live date for the Leeds Clean Air Charging Zone giving affected businesses clarity to help them prepare for the zone's introduction.
