Question to the Department for Environment, Food and Rural Affairs:
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 road links within the South East non-agglomeration zone are expected to exceed the nitrogen dioxide limit value in each of the last five calendar years of the non-compliance period.

The most recent national compliance assessment for 2023 reported one road link in the South East non-agglomeration zone as being in exceedance of the annual mean limit value for nitrogen dioxide. This road link is a stretch of the A34 in the Vale of White Horse. We don’t hold up-to-date detailed modelled projections to predict the impact of all current policies on future NO2 concentrations, however current indicative estimates suggest that this road link will become compliant with the limit value in 2028.
