Air Quality Plan FAQs

  • Why does Derby need a Local Air Quality Plan

    In 2015 Derby City Council was identified by DEFRA, along with four other cities (outside London), to take early action to improve roadside nitrogen dioxide (NO2) emissions. Initially, the government direction required local authorities to implement clean air zones by 2020.


    There is a requirement to reduce the level of NO2 in the air to below 40μg/m3 as soon as possible in line with EU and UK statutory regulations. Derby City Council has undertaken work to predict the NO2 roadside emission levels (as per the requirements for modelling set out by government). This has identified that Stafford Street, near to its junction with Friar Gate, would exceed this limit if no action was taken.


    In July 2017 government launched a revised National Air Quality Plan for NO2 emissions. This plan sets out that local authorities should develop measures to achieve compliance in their areas. The locally developed scheme (the local air quality plan) has to be submitted to the Secretary of State for approval. If approval is given, then the Council will be legally obliged to implement the scheme.

  • What technical evidence is available to demonstrate that the Local Air Quality Plan does achieve compliance in the shortest possible time?

    The technical reports provided represent the latest available evidence emerging from the feasibility study. The results of further analysis will be added to these reports as work is completed in stages.

    We are continually working with government to finalise the technical reports as part of the Local Air Quality Plan business case process.

    The work is required to be carried out in accordance with the governments’ methodology and the project is very complex. We will update the website as and when further information becomes available.

    We will update the website as and when further information becomes available.

  • When will more information be provided on the details of the Clean Air Incentive Scheme including mobility credits?

    We are continuing to work with Government to develop the Clean Air Fund Scheme (CAF). We have undertaken an impact assessment of the preferred option. This has helped further inform the various mitigation measures we require by identifying the localised impacts on various stakeholders. This has been fed into the Clean Air Fund (CAF) proposals.

    There are currently two elements of the CAF:

    1. A Clean Air Incentive Scheme (targetted mobility credit scheme) - this will help with the permanent removal of older vehicles from the fleet with the offer of mobility credits to encourage more sustainable and active travel options.  This will be targetted to address those most impacted by the delivery of the traffic management scheme.

    2. Infrastructure - to support the acclerated uptake of electric vehicles, including additional vehicle charging points and other traffic management measures to further promote the update of electric vehicles.  This will be targetted in those areas where impact is greatest i.e. vehicles that use the traffic network in the area of predicted exceedence.

    The Derby CAF would follow successful examples of similar programmes that have resulted in polluting vehicles being removed from the roads in cities across the world, and would demonstrate Derby’s commitment to helping improve the city’s environment.

    Further updates will be provided when more information becomes available.

  • What are the next steps for refining the design of the Local Air Quality Plan?

    We are continuing to refine the scheme design and has part of this have considered the results of the two phases of consultation and further technical evidence that has since become available.

    The indicative plans used during the consultation showed the preliminary design. Due consideration has been given to the concerns raised and suggested solutions and where appropriate the schemes have been refined to reflect those.

    The detailed design of the LAQP is now finalised and will be published on the website soon.

  • How have suggestions for the Local Air Quality Plan supporting measures be considered and prioritised?

    The consultation results have been fed into the initial identification of the mitigation measures and into the further development of the Clean Air Fund (CAF) bid. The mitigation measures are now being finalised following further feedback from stakeholders and Government, and technical evidence, and will be confirmed as part of the final business case.

    The CAF is a competitive bidding process and the criteria for the bid is restricted to measures that mitigate the impact of the delivery of the roadside NO2 plan. Some of the issues therefore raised during the consultation might not be able to be addressed through the preferred option refinement or CAF. However, further consideration will be given to any other funding sources available to deliver other measures to support the wider air quality agenda.

  • How does the Local Air Quality Plan ensure behaviour change is encouraged and enabled?

    The primary objective of the Local Air Quality Plan as specified by Government is to address roadside NO2 limits in the shortest possible time in order to achieve legal compliance. As part of the business case process we have to demonstrate that the local air quality plan proposals address the compliance issue and that the Clean Air Fund proposals address and mitigate any impacts. The plan has robust evidence to demonstrate this and will be finalised as part of the full business case process.


    The Council recognises the importance of behaviour change and encouraging public transport use and active travel. The Council are already implementing behaviour change projects and are currently managing an extensive behaviour change programme, which runs until 31st March 2020, following a successful bid to the Department for Transport’s Access Fund. The Cycle Derby project also offers a wide range of services to support and enable people from all walks of life to cycle.

  • What are the next steps for the Local Air Quality Plan project?

    An outline business case was submitted to Government on 25th February 2019.  The OBC put forward a traffic management solution to tackle the one site of exceedance identified on Stafford Street and includes several junction design changes and a significant modernisation of the Council's urban traffic management system.  The information provided as part of the outline business case will now be further refined for the full business case stage.

    The full business case will be submitted to Government on 26th March 2019.  Implementation of the scheme proposals will then be subject to the necessary approvals and funding from the Secretary of State.

    We are confident that the essential traffic and network management scheme elements to address the roadside NO2 exceedance limit will be completed in 2019, subject to timely approvals process and funding being made available.  the additional measures to maintain compliance are expected to be delivered over the following year with further supporting schemes delivered over the lifetime of the project until 2025 (subject the necessary Secretary of State approvals).
