ANCA has published the 2025 aircraft noise contours for Dublin Airport. The contours present the annual average aircraft noise levels in a standardised European format for both the night-time and the full 24-hour periods of the year.

A planning application to expand Dublin Airport’s annual passenger capacity from 32 to 40 million is under review. ANCA has assessed the proposal, identifying measures to reduce aircraft noise impacts and updating noise objectives. A 14‑week public consultation is now open.
