What is the Clean Air Charging Zone (CAZ)?

On 6th January 2020, Leeds City Council will introduce the city’s Clean Air Charging Zone (CAZ) to reduce air pollution and protect the health of everyone in Leeds.

The CAZ will reduce air pollution in Leeds by encouraging businesses to transition to cleaner, less polluting vehicles that won’t be subject to daily charges. It will be the largest zone of its kind in the country.

To help businesses switch to cleaner vehicles and avoid charges, we will be offering a range of support packages for affected businesses based within the boundary of the CAZ.

How does air pollution affect my health?

What can I do?



Let's clear a few things up


Cyclists and pedestrians are exposed to more air pollution than drivers


Wrong. As well as being better for your health and fitness, evidence shows that cyclists and pedestrians are also less exposed to air pollution than people in vehicles. This is because your air filter probably doesn’t remove pollution from the air it circulates and being on the road itself means that your vehicles is surrounded by exhaust fumes. Pedestrians and cyclists are also less exposed because even 1 metre away from traffic, there is considerably less pollution than on the road itself.


Turning your engine on and off again whilst sat in traffic releases more emissions than leaving it running.


Whether you’re stuck in traffic or just waiting to pick someone up, if you think that your car might be stationary for more than 2 minutes it’s better to turn your engine off than leave it running. Doing so will reduce the amount of gases harmful to our health and the environment that your car emits. It’s an easy way to reduce your own contribution to air pollution!
