Businesses have been urged to start planning for the introduction of the Leeds clean air zone (CAZ) after the Government approved the city council’s proposals. The CAZ, which will come into effect on January 6, 2020, will encompass the majority of the city and non-Euro VI HGVs, buses and coaches will face a £50 daily charge for driving in the zone, while non-Euro 6 diesel and non-Euro 4 petrol taxis and private hire vehicles will incur a £12.50 charge. Private vehicles will not be charged.
