Nitrogen Dioxide: Pollution Control
The question
To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 8 July 2025 to Question 63553 on Nitrogen Dioxide: Pollution Control, what nitrogen dioxide concentrations were monitored in the Greater Manchester reporting zone at (a) A34 Bridge Street, (b) A34 Quay Street, (c) A664 Shudehill, (d) Lever Street in Manchester, (e) A49 Chapel Lane and (f) King Street West in Wigan.
Answered by Emma Hardy
Greater Manchester’s Clean Air Plan modelling predicted localised nitrogen dioxide (NO2) hotspots in 2026 at A34 Bridge St, A34 Quay St, A664 Shudehill and Lever St in Manchester, and at A49 Chapel Lane and King St West in Wigan.
The monitored annual mean NO2 concentrations in 2023 on A34 Bridge Street, A664 Shudehill and Level Street in Manchester were 44.9, 58.6 and 55.7 µg/m³ respectively. Defra does not currently hold finalised 2023 monitoring data for the localised hotspots on A34 Quay Street in Manchester, and A49 Chapel Lane and King Street West in Wigan. We are working with Greater Manchester to obtain up to date monitoring data and this will be assessed as it becomes available.
