Bristol’s Clean Air Zone
The Government set legal limits for pollution and we have to introduce a Clean Air Zone (CAZ) to ensure Bristol meets those limits within the shortest possible time.
A major source of air pollution in cities is road traffic, particularly diesel engines. Air pollution affects everyone in Bristol, especially children, older people and those with heart, breathing and underlying health conditions.
In February 2021 the council’s cabinet approved the Full Business Case for our chosen CAZ which will now be submitted to Government. Our chosen option offers a balance between improving air quality and the need to support businesses as much as possible.
Government will confirm if they accept our Full Business Case in the spring. The earliest we would implement the CAZ is October 2021.
No vehicles are banned from entering the CAZ but older and more polluting vehicles will have to pay a daily charge. It is estimated over 71% of vehicles are already compliant and so only a minority of vehicles driving in the CAZ will be charged. In subsequent years this percentage will decrease as more people take advantage of the available financial support to switch to a cleaner vehicle or a different mode of transport.
- Charges would not apply to Euro 4, 5 and 6 petrol vehicles (roughly 2006 onwards).
- Charges would not apply to Euro 6 diesel vehicles (roughly end of 2015 onwards).
We appreciate that the implementation of a charging CAZ will be a challenging transition for some residents and businesses. We will support those most impacted and are calling on the Government to provide the necessary funding to do this.
We’ll do what we can to support people who are most impacted by the CAZ, including low income workers and businesses and residents inside the zone.
We’ll share more information about exemptions and the financial support that will be in place to help people switch to a cleaner vehicle once our business case is approved in the spring.
