There is a high level of uncertainty in government’s model for assessing pollution levels, which may mean that further areas of poor air quality might be missed by the programme. Government uses a national model to identify areas that are … Read more
Government Response
The government states that the best available evidence has been used to identify areas exceeding pollution limits and that the national model meets uncertainty requirements. They will continue to improve the model and have increased the number of monitoring locations. They will consider local authority monitoring data if it meets AQSR requirements.

Central government has not always got the balance right in how it works in partnership with local government, having been prescriptive in some respects, while seeming to avoid responsibilities that naturally sit at a national level in others. The best … Read more
Government Response
The government agrees with the recommendation. It states that local authorities are responsible for developing Clean Air Plans, with support from a dedicated account manager, and that each local authority has the flexibility to identify measures other than Clean Air Zones. They will write to the Committee by the end of February 2023 with a further update on how it is engaging with local authorities.

Although calculating an exact figure may be difficult, with Departments claiming it would be a great deal of effort to produce something not necessarily precise, Government could do more to improve the transparency of cross-government public spending that has an … Read more
Government Response
The government disagrees with the recommendation, stating that the resource required to disaggregate spend driving air quality benefits across the variety of complex policies would be disproportionate, estimates produced would be misleading, and would not support accountability/transparency.

Government Response
The government agrees that the best available evidence is used to identify areas in exceedance and bring them into the programme, and that they continue to work with experts to improve the model and have set up a new monitoring network, and where monitoring identifies a potential breach, local authorities can share the information with the Joint Air Quality Unit.
