Leeds’ planned Clean Air Zone (CAZ) is “no longer required” after a joint review found that its aims have already been achieved thanks to businesses switching to cleaner vehicles faster than expected.
Senior councillors will discuss the conclusions and proposals to voluntarily introduce new air quality targets that go further than the national standards at a meeting of the council’s Executive Board next week.
More than 90% of buses and 80% of heavy goods vehicles driven in the city now use cleaner Euro VI engines and therefore wouldn’t be charged if a zone was introduced.
Research shows that the newer vehicles emit significantly fewer emissions than older models, especially when travelling at the slower speeds often travelled in urban environments. Nearly half of the city’s licensed taxi and private hire cars are also now hybrid or electric.
Because of the dramatic shift to cleaner vehicles, the joint review by Leeds City Council and central government found that air pollution in Leeds on key routes is below legal limits and is not likely to exceed them again—even if traffic were to return to ‘normal’ levels or slightly higher.
Transport infrastructure improvements and the surging popularity of ultra-low emission vehicles in Leeds are further accelerating improvements to the city’s air quality.
The council has written to the government requesting to keep £6.9 million of CAZ funding that Leeds had previously secured to ‘lock in’ the full extent of air quality improvements.
The money would be used to continue offering grants to help local businesses switch to cleaner vehicles as well as to provide free licensing costs to drivers of less polluting taxi and private hire cars.
Leeds will also be able to keep and repurpose the ANPR camera infrastructure that had been installed to monitor and enforce the zone.
In the event that air quality declined for any reason, the council retains this infrastructure and could seek support from central government to introduce a Clean Air Zone.
As part of an updated air quality strategy being brought forward early next year, Leeds City Council is proposing to voluntarily introduce stricter new targets for local air quality that are aligned with World Health Organisation guidelines.
“When we consulted on the CAZ in 2018, we said that we hoped that no one would be charged because businesses would switch to less polluting vehicles before the charging system takes effect. That is exactly what has happened,” said Councillor James Lewis, Deputy Leader for Leeds City Council and Executive Board member with responsibility for air quality.
“We have achieved the aims of the Clean Air Zone without having to charge a single vehicle. If Leeds were to introduce a CAZ today, only a fraction of vehicles would be affected because the vast majority of businesses are now driving cleaner vehicles than they were just a few years ago.
“While we celebrate that our air is cleaner than ever, and cleaner than some other UK cities, this council also recognises that air pollution remains the biggest environmental threat to our health.
“That’s why we’re considering voluntarily introducing even stricter targets for Leeds, aligned with WHO guidelines. We will continue working hard to protect the health of everyone in Leeds from the effects of polluted air.”
