Toxic fumes are harmful to our health. We are committed to cleaning up Bristol’s air to ensure everyone can live and work in a healthy environment.
In Bristol we’re most concerned by nitrogen dioxide (NO2) and very small particulates. A major source of these pollutants in cities is road traffic, particularly diesel engines.
The council has a moral and legal duty to ensure the city’s air quality meets the legal limits of air pollution in the shortest possible time. This is a legal requirement and something we’ve been directed to do by government. There are specific areas within Bristol that have particularly poor air quality and it is our responsibility to correct this.
If the recent positive changes to how we travel (such as increased walking and cycling rather than driving) continue and Bristol can sustain improved air quality and less traffic in the city, we might not need to charge polluting vehicles to comply with our legal duties.
However, if people’s travel behaviours return to how they were before, traffic builds up and pollution increases and stays above legal limits, we will need to introduce one of the two Clean Air Zones.
