The additional local monitoring data referred to in the Answer of 7 September 2026 may include monitoring data collected by local authorities in fulfilment of their local air quality duties, including data reported through Annual Status Reports. The precise scope of local authority monitoring data to be incorporated is still being finalised as the new projections are developed and will depend on data availability and modelling requirements.

To ask the Secretary of State for Transport, pursuant to the Answer of 15 June 2026 to Question 7215 on Railway Stations: Nitrogen Dioxide, what the estimated cost is of measures contained in Air Quality Improvement Plans that have not yet received funding approval.
To ask the Secretary of State for Transport, pursuant to the Answer of 15 June 2026 to Question 7215 on Railway Stations: Nitrogen Dioxide, what the estimated cost is of measures contained in Air Quality Improvement Plans that have not yet received funding approval.
Network Rail does not hold or collate information centrally on estimated costs of measures within Air Quality Improvement Plans. Funding and delivery are managed at a local level.
To ask the Secretary of State for Transport, what the total projected cost to the public purse is for Network Rail to develop and deliver Air Quality Improvement Plans (AQIPs) across all managed stations with nitrogen dioxide levels of 40µg/m³ or more by 2030; and what budget has been allocated...
To ask the Secretary of State for Transport, what the total projected cost to the public purse is for Network Rail to develop and deliver Air Quality Improvement Plans (AQIPs) across all managed stations with nitrogen dioxide levels of 40µg/m³ or more by 2030; and what budget has been allocated...
The development and delivery of Air Quality Improvement Plans (AQIPs) across Network Rail’s managed stations cannot be assigned a single total projected cost to 2030. This is because the measures required vary significantly by location and over time. Stations with nitrogen dioxide (NO₂) levels only slightly above the 40 µg/m³ improvement indicator may require relatively low-cost actions, such as anti-idling campaigns or driver briefings. In contrast, stations with higher levels may require more complex long-term solutions, including ventilation upgrades or air cleaning technologies.
In addition, the number of stations requiring AQIPs is not fixed. Some stations may improve and therefore no longer require an AQIP, while others may be newly identified where exceedances occur. This variability makes it difficult to accurately forecast overall programme costs.
No central or national budget has been allocated specifically for AQIP delivery or associated engineering measures. While individual AQIPs may include estimated costs for proposed actions, funding approval and delivery are managed at a local level.
