Environmental Protection Wales 3 Minutes Read · published February 12, 2026 Flag of Wales

Cardiff, Wales publishes local air quality information and manages Air Quality Management Areas (AQMAs) through the council's environmental health and pollution control services. This guide explains where to find Cardiff Council's official air quality data, how local bylaws and management actions are applied, and how to report problems or request monitoring. Use the council pages and official reports to confirm legal standards, local AQMA boundaries and procedural steps for complaints, monitoring requests and enforcement.

How to check local air quality data

Start with Cardiff Council's air quality pages for current monitoring results, AQMA maps and the latest Annual Status Report. The council maintains monitoring sites and summary data that explain which pollutants are measured locally and where exceedances have been recorded[1].

Check the council's AQMA map first to see if your street lies inside a declared area.

The council implements Local Air Quality Management duties under national legislation and provides guidance on sources like transport, industry and construction.
