Voices: Clean air for Bristol is taking too long

Bristol Clean Air Alliance is an alliance of groups and individuals across Bristol.  It is a non-partisan group, united by a desire to see an effective Clean Air Plan in Bristol. We are concerned at the slow progress being made towards proposing a plan.

We are motivated not by political point-scoring, but by a concern for the health of groups that are particularly vulnerable to air pollution, like the young and old, and those with respiratory illnesses.

It is taking too long

Air pollution is now the most serious public health threat facing UK towns and cities.

We welcome the Cabinet paper’s announcement of Clean Air Plan proposals. We have been disappointed by the slow progress so far, and it is good to at last see recognition of the serious action that is needed.  Even so, it seems clear that Bristol is struggling to meet its own deadline of delivering an Outline Business Case [a final plan for an approach to cleaning Bristol’s air] to government in September.

Other cities across the UK have faced the same issues and made better progress. Take Birmingham as an example. The Labour administration will implement a charging Clean Air Zone from January 2020 that includes cars, which is projected to deliver compliance by 2022. They are reducing the impact on the less well-off by delaying the charge for those who earn less than £30,000 a year, and offering financial help to switch to a cleaner car or for using public transport. A similar exemption applies for residents living within the Zone. They are looking beyond compliance with current legal limits, and embedding the clean air plan in wider transport strategy, including behaviour change initiatives.

We are concerned that Bristol’s plans will take too long to deliver compliance with air quality limits – 2023/4 or 2025 depending on the option chosen. The council is legally obliged to deliver compliance “as soon as possible”, and it is does not seem acceptable to propose a plan that will take up to five years to deliver compliance.

Serious action is needed

It is instructive that even a Class D (including cars) medium charging Clean Air Zone delivers compliance only by 2027+ (2027 everywhere except 2030 for Upper Maudlin Street).  2027+ is later than other cities that are implementing a charging zone. It implies that Bristol has a worse problem than other cities, possibly because of persistent congestion at places where the pollution gets trapped by buildings in Bristol’s narrow streets?

We doubt that Bristol will achieve compliance quickly without reducing the number of polluting cars on city centre roads.  Low-emission buses and taxis will help, but cars are more numerous, and they can be just as polluting as larger vehicles, especially when they are stuck in congested traffic.  We therefore support the proposed diesel car ban. A car ban zone (Option 2) is more draconian than a charging zone (Option 1), but seems necessary because Bristol seems to have a worse problem than other cities.

The bigger picture

We need to think wider than the narrow aim of delivering compliance with artificial air pollution limits. No level of air pollution is safe. What matters is not compliance in hotspots but the health impact over the whole city. We urge the council to build on the warm words of the Bristol Transport Strategy and Joint Local Transport Plan by taking enthusiastic ownership of measures to encourage shared transport and active travel, and show a sense of urgency and drive to deliver them.

We acknowledge that the council has made some steps in the right direction. It is supporting initiatives such as no-idling zones, School Streets temporary road closures, and cleaner buses and taxis. The Mayor’s planned Bus Deal is welcome too, but it will only be effective if the buses have enough dedicated space on the roads to allow them to get through congested traffic (such as extending the bus lane on the M32, as is proposed for Option 1). And it is only one part of the transport plan that Bristol needs.

A charging Clean Air Zone and a zonal older-diesel car ban are sticking-plaster measures. What is needed is a general reduction in single-user vehicles so that our narrow city centre roads can meet the travel demand whilst minimising air and noise pollution. We think the Mayor is tying one hand behind his back by ruling out demand management measures such as a congestion charge that includes all cars, or a Workplace Parking Levy, to reduce the volumes of private motor traffic in the city centre. We recognise that these are politically difficult, but at some stage this nettle will have to be grasped – alongside a programme of improvements for other transport modes. Nottingham did this some years ago, and it seems no coincidence that it is one of the few cities that has not had to introduce a Clean Air Zone in order to comply with legal air pollution limits.

  • I have been troubled for some time by drivers sitting in stationary vehicles with their engines idling whilst parked. This causes unnecessary & excessive air pollution & is especially noticeable where buses which are designed to cut out when they stop at bus stops are restarted again within 8 seconds by their drivers for apparently no reason. I have observed diesel car & lorry drivers sitting in their vehicles eating sandwiches or having long conversations on their mobile phones with their engines running. Sometimes lorry drivers leave their lorries with engines running whilst they attend to other matters outside their vehicles. Idling engines is an offence in law and idling engines are more polluting than when driving. Can nothing be done to make drivers more aware of the pollution they are causing by continuing this practice.


  • On reading the national report on air quality it was apparent that the main area in Bristol causing concern was the end of the M32 on Newfoundland Way where hundreds of vehicles are sitting in queues for as long as 15 to 20 minutes all with their engines running. It was suggested that a banner might be hung from the bridges to simply ask motorists to cut their engines whist waiting in the queue. The mayor rejected the idea.
