Local concerns about Clean Air Zone proposals

TRESA supports efforts to clean up the air in Bristol. However, at our recent public meeting the following issues were raised in relation to the proposed Clean Air Zone and diesel ban zone. A map of the Zone is included below. TRESA has contacted https://www.cleanairforbristol.org/ seeking clarification of these issues and will make further information available as we receive it.

Diverted traffic (air quality)

Totterdown is just outside of the CAZ and may be affected by non-compliant commercial vehicles diverting to avoid the charge. This could increase the number of non-compliant vehicles driving around Totterdown and consequently an increase in congestion and air pollution.

  • Non-compliant commercial vehicles heading towards the city on Bath Road may turn left at Three Lamps Junction, driving up Wells Road and then turning right along St John’s Lane
  • The Stanley Hill rat run from Bath Road to Wells Road may also become even worse
  • Non-compliant commercial vehicles driving towards the city on Wells Road may turn left onto St John’s Lane


As well as displaced traffic driving through the area, Totterdown may also be affected by an increase in non-resident parking as people try to avoid entering the zone. This is likely to be exacerbated by the new University campus at Temple Quarter.

Access for diesel private car drivers

Temple Meads train station and Bristol bus station are both within the diesel car ban zone, making it impossible for someone with a diesel car to drop off or pick up family members or friends (special concern was expressed for disabled passengers) between 7.00am and 3.00pm without incurring a substantial fine (modelled to be £60, increasing to £120 if not paid within 14 days).

Bristol Royal Infirmary and Bristol Children’s Hospital are within the diesel car ban zone, making it impossible for someone with a diesel car to drive someone to hospital in an emergency without incurring the substantial fine.

Cabot Circus shopping area will not be accessible to people driving a diesel car until after 3.00pm e.g. if they are buying heavy items.

Additional questions

When and where will the future Park & Ride facility be implemented on the A37 Wells Road?

Are there plans for a freight consolidation site for south Bristol to reduce the number of large lorries driving into central Bristol along the Bath Road and Wells Road?

As part of the improvements to the Wells Road bus route through Totterdown, can a 20mph limit be imposed and enforced?

What is the definition of a commercial vehicle? Does this include people with a small business who use their vehicles for business purposes?

The two-zone proposal seems complicated to understand, potentially more expensive to set up and enforce, and will effectively ban some people from accessing important city centre sites for a large part of the day. Is a Class D zone (charging all non-compliant vehicles but not imposing a ban) still being modelled as an alternative?
