Table 2 Description of the B-CAP including CAZ using the TIDieR checklist

From: Study Protocol. Evaluating the life-course health impact of a city-wide system approach to improve air quality in Bradford, UK: A quasi-experimental study with implementation and process evaluation

Brief name

Bradford Clean Air Plan: Breathe Better Bradford

Why

To reduce NO2 pollution levels to legal limits (40 μg/m3) as quickly as possible.

A Class C CAZ will charge non-compliant buses, coaches, heavy goods vehicles, vans, minibuses, taxis and private hire vehicles charged a daily fee to enter the zone.

Proposed to instigate desired behavioural responses towards a reduction in most polluting vehicles and an increase public transport use, and active travel.

Rigorous modelling (informed by routine monitoring and traffic fleet data) has identified at least 16 core link roads which exceed legal pollution limits, requiring a reduction of 1-18 μg /m3; activities included within the B-CAP have been estimated to achieve up to an 18 μg /m3 reduction in NO2 (based on 2018 baseline data). However, it is hoped that the ambitious nature of the plan will mean air quality is improved beyond these limits by harnessing the power of the ‘system’ (e.g. transport, planning, and public health) to work together to further improve outcomes.

What: Materials

Network of 330 automatic number plate recognition cameras, 16 km of digital ducting in 6 new digital rings around the city.

A public website contains information for the public and businesses: https://www.bradford.gov.uk/breathe-better-bradford/breathe-better-bradford/

What: Procedures

The Clean Air Zone is planned to go live in 2022. Daily charges for non-compliant vehicles will be £7 for taxis, £9 for light good vehicles and £50 for heavy goods vehicles.

Prior to the go-live date, local businesses and taxi are able to access grants to contribute to the cost of upgrading or replacing their vehicles to CAZ standards with 25% of all grants prioritised for electric vehicles.

Exemptions will be provided for local small/medium enterprises (SMEs), schools and charities.

The CAZ to be supported by a range of other initiatives including: electric bus routes in key parts of the city with road space allocation to prioritise buses and reduce journey times; installation of alternative energy centres providing cost effective green refuelling/recharging facilities; travel planning with businesses to promote car sharing, active travel and public transport use amongst employees.

Who provides

The intervention is implemented by the Clean Air Plan delivery team within Bradford council. This includes an operations team, grants and business support, monitoring and evaluation, and ultra low emission vehicle programme.

How

Drivers can choose to pay the daily charge up to 7 days before and 7 days after entry. ANPR cameras at CAZ entry points will identify non-compliant vehicles by linking up with the Driver and Vehicle Licensing Agency database. Penalty charge notices will be sent to owners who do not pay within 7 days.

Grants and exemptions will be applied for via the Breathe Better Bradford website.

Where

The Clean Air Zone boundary encompassing the city’s inner ring road, and a key corridor out to the North West of the city. It encompasses an area of 22.4 km2, primarily the most deprived inner city wards but including less deprived wards on the outskirts of the city. The boundary contains ~ 20% of the Bradford population.

When and how much

The Clean Air Zone is planned to be live until legal levels of pollution are reached

Tailoring

Clean Air Zone interventions are complex and tailored within each city that they are implemented within.

How well

A number of measures will be used to explore whether the B-CAP is implemented as intended. These will include: fleet composition; number of penalty notices issued; number of vehicles upgraded; number of grants applied for
