ANCA has invited the public to have their say on a planning bid that would raise Dublin Airport’s annual passenger cap from 32 million to 40 million, alongside new infrastructure, with draft noise-reduction measures proposed for nearby homes.

The consultation is open until 3 September 2026.

The airport authority, daa, has lodged application F23A/0781 with Fingal County Council seeking approval to increase permitted passenger numbers and to provide associated airport infrastructure. The Aircraft Noise Competent Authority (ANCA) has assessed the potential aircraft noise implications and, in its draft decision, proposes expanding eligibility for home sound insulation so that more households can access measures designed to cut indoor noise levels by five decibels.

As part of its assessment, ANCA has also amended the Noise Abatement Objective (NAO) for the airport and completed environmental assessments of the proposed measures. The revised objective aims to further reduce the number of people experiencing annoyance and sleep disturbance from aircraft noise.

Director of Services at ANCA, Ethna Felten said: "I would encourage anyone with an interest in Dublin Airport to read our draft decision and to submit their opinion. This consultation is an important part of the process because it allows us to hear directly from the public and it gives us different perspectives to consider. Dublin Airport is very important to us all, both socially and economically, but its existence presents difficulties for the neighbouring communities, due to the level and the type of noise that's generated. So,it is important to look at what our draft decision proposes and for people to have their say before the consultation closes on September 3rd."
