Air Quality Plan FAQs

We will continue to refine the plan with the submission of the final business case to central government expected in early 2019. This will include a plan to demonstrate that the measures proposed are appropriate and proportionate for the situation in Derby with the necessary evidence to demonstrate that the plan meets the primary aim of the project: to achieve roadside NO2 compliance in the shortest possible time frame.

After giving due considerations to all the comments received during the consultations we will further refine the proposals and the mitigation measures.

It is anticipated that the full business case will be submitted to central government in March 2019. Implementation of the scheme is anticipated to start in 2019, subject to the necessary approvals and funding being made available.

The primary objective of the Local Air Quality Plan as specified by Central 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 will need to have robust evidence to demonstrate this.

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 behavioural 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.

The consultation results will feed into the identification and confirmation of the mitigation measures and into the further development of the Clean Air Fund (CAF) bid. Full consideration of the final mitigation measures will need to be undertaken once the distributional and health impact assessment is completed for the 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.


We are continuing to refine the scheme design and will feed in and consider the results of the second round of consultation as part of this.

Any action required as a result or additional mitigation requirements will be reflected as part of the final business case submission.

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

The detailed design of the LAQP is ongoing and updates will be provided on the website as the scheme designs develop. Feedback on these will be welcomed.

We are continuing to work with Government to develop the Clean Air Incentive Scheme (CAIS). We are undertaking an impact assessment of the preferred option. This will help further inform the various mitigation measures we require by identifying the impacts on various stakeholders. This will be fed into the Clean Air Fund (CAF) proposals.

As and when further information becomes available we will provide updates.

There are currently two elements of the CAIS:

  1. A vehicle replacement scheme – it is envisaged that the CAIS will be targeted at individuals from low income households and small business owners who would find it most difficult to adopt options for low emission travel. Vehicle owners whose current vehicle exceeds set emission thresholds, would receive a grant towards a low emission vehicle.
  2. Mobility Credit Scheme – with low income households also having the option to shift to an alternative form of transport through the use mobility credits which would include the use of public transport.
    The Derby CAIS would follow successful examples of similar programmes that have resulted in polluting vehicles being removed from the road in cities across the world, and would demonstrate Derby’s commitment to helping disadvantaged groups improve the city’s environment.

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.

It is expected that further technical evidence will be available by end February 2019.

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.
