Nitrogen Dioxide: Pollution Control
The 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 the (a) West Midlands urban area, (b) Bristol urban area, (c) Sheffield urban area and (d) the Potteries are expected to become compliant.
Answered by Emma Hardy
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 |
Liverpool Urban Area | 2029 |
Greater London Urban Area | 2024 |
Greater Manchester Urban Area | 2026 |
Nottingham Urban Area | 2024 |
Portsmouth Urban Area | 2026 |
Reading and Wokingham Urban Area | 2024 |
