This dashboard shows the latest results for air quality indicators collected by regional councils and unitary authorities. Indicators are shown against the National Environmental Standards for Air Quality (NES-AQ). Where no national standards exist for the air quality measurements shown, the data are compared against other guidelines (e.g. World Health Organization (WHO) 2021 guidelines, Ambient Air Quality Guidelines (AAQG)).
