Consultation on Traffic Clean Air Zone options

Closes 12 Aug 2019

Opened 1 Jul 2019


Pollution can make the air we breathe bad for our health. Air pollution has been a problem in Bristol and many UK cities for a long time. 

The most concerning pollutants within Bristol are nitrogen dioxide (NO2) and very small particulates. These pollutants are invisible. 

UK and EU limits on levels of NO2 are currently breached in Bristol. Local authorities are legally required to reduce levels of NO2 as soon as possible to comply with these health-based standards and this consultation is concerned with reducing the levels of NO2 in the shortest possible time.

What we are proposing

We are proposing two alternative options, which our work so far shows would bring NO2 levels to below legal limits in the shortest possible time. (This is known as achieving “compliance”.) The council is under a legal duty to achieve this.

Option 1 Clean Air Zone (private cars not charged)

A zone in which non-compliant (older, more polluting) buses, coaches, taxis, heavy goods vehicles (HGVs, i.e. goods vehicles over 3,500 kg) and light goods vehicles (LGVs, i.e. goods vehicles not exceeding 3,500 kg) would be charged a fixed sum for each day they are driven in the zone. The charge would only apply once daily. We propose that the charge would be £9 per day for non-compliant taxis and LGVs and £100 per day for non-compliant HGVs, buses and coaches.

Option 1 would also include a scrappage scheme (up to £2,000) for diesel cars and a number of additional targeted measures to reduce pollution on the worst affected streets. These additional targeted measures include a part-time ban on all diesel cars on Upper Maudlin Street and Park Row (in front of the children’s hospital); some new HGV weight restrictions; bus lanes on the M32 and Cumberland Road; and using existing traffic signals to control the amount of traffic entering congested areas with poor air quality.

Option 2: Diesel car ban

Banning all diesel cars from driving in a specific central area from 7am to 3pm, seven days a week (this would not apply to taxis/private hire or emergency services). Other measures, including a scrappage scheme, could also be included.

We are consulting with you now on these two options in order to meet the Government’s timetable for submitting our Outline Business Case in September 2019. Our technical work is ongoing to estimate more precisely what the date of compliance would be for each option. This information is due to be available in the week commencing 15 July 2019 and will be provided as soon as it is available so that you can take it into account in your response.

Why We Are Consulting

The Traffic Clean Air Zone consultation is your chance to tell us what you think about the options we propose for improving air quality in Bristol.

Your views are important and will be considered by the Mayor and Cabinet when they decide in September 2019 what approach to include when the council submits a Full Business Case to Government in the coming months, setting out how it will achieve compliance in the shortest possible time.

Please complete the online survey and return to us by Monday 12 August using the link below.

If you cannot complete the survey online, you can request alternative formats by emailing or by calling 0117 352 1397.
