The Annual Air Quality Bulletin 2023 assesses how many times Irish air quality breached the limits set in the ‘Clean Air For Europe’ (CAFE) Directive.

The daily limit for PM10 is 50 ug/m3. The limit is deemed breached if more than 35 exceedances occur during the year. The hourly limit for NO2 is 200 ug/m3. The limit is deemed breached if more than 18 exceedances occur during the year. The target value for Ozone for the protection of human health is 120 ug/m3. The limit is deemed breached if more than 25 exceedances occur per calendar year, averaged over 3 years.

This assessment is based on monitoring data collected from the National Ambient Air Quality Monitoring Network during the year 2023.
