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, which localised hotspot is expected to delay compliance with the nitrogen dioxide limit value in Newcastle upon Tyne.
Answered by Emma Hardy
The localised hotspot in Newcastle-upon-Tyne is located on Stephenson Road A1058. The high nitrogen dioxide (NO2) concentrations observed here are due to several local factors including high traffic volumes, queuing traffic, an incline in the road that requires vehicle acceleration and overhanging trees that partially trap pollution. There is considerable uncertainty in the estimate of when this location will become compliant with the annual mean NO2 limit value. The rest of Newcastle-upon-Tyne is expected to become compliant by 2029.
