Asked by Tim FarronLiberal DemocratDepartment for Environment, Food and Rural AffairsTabled Answered 13 January 2026UIN 103223

The question

To ask the Secretary of State for Environment, Food and Rural Affairs, whether any hotspots in zones other than the five zones identified in the Compliance Assessment Summary 2024 exceeded the nitrogen dioxide annual limit value in calendar 2024.

Answered by Emma Hardy

The localised hotspots identified through Defra’s national modelling and monitoring networks are published annually on UK Air (https://uk-air.defra.gov.uk/) as part of the national compliance assessment under the Air Quality Standards Regulations 2010. Localised hotspots that have been identified by local authority-owned monitoring are published in their respective annual status reports.
