Nitrogen Dioxide: Pollution Control
- Question
-
To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 26 March 2025 to Question 39816 on Nitrogen Dioxide: Pollution Control, in which year he estimates that the (a) West Yorkshire urban area; (b) Coventry and Bedworth, (c) Liverpool urban area, (d) Great London urban area, (e) Greater Manchester urban area, (f) Nottingham urban area, (g) Portsmouth urban area and (h) Reading and Wokingham urban area will become compliant.
- Answer
-
Predicting when locations will comply with the annual mean limit value for nitrogen dioxide is inherently uncertain. Our current estimates reflect the impact of agreed local Clean Air Plans and are based on 2023 data from Defra’s national monitoring networks and national modelling, as well as local authority-owned air quality monitoring and modelling. 2023 is the most recent year of fully ratified monitoring data available. As additional years of data become available or where additional measures are agreed some of these predictions are likely to change. Current estimates for when the following reporting zones will become compliant are:
West Midlands Urban Area
2032
Bristol Urban Area
2031
Sheffield Urban Area
2031
The Potteries
2032
South East
2028
West Yorkshire Urban Area
2029
Coventry and Bedworth
2026

Greater London Urban Area
