The Dublin Airport passenger cap review has moved forward, with Transport Minister Darragh O’Brien preparing to formally apply to An Coimisiún Pleanála for environmental assessments required under the Dublin Airport (Passenger Capacity) Act 2026.
The development could influence how passenger growth is managed at Ireland’s largest airport, while a separate planning application examines new infrastructure intended to expand capacity and support future aviation demand.
Dublin Airport passenger cap process enters assessment stage
The Department of Transport said the Minister intends to submit an environmental impact assessment report and a Natura impact statement received from daa to An Coimisiún Pleanála. The documents follow daa’s application in August to make an Order under the 2026 legislation.
The assessments will include a full public consultation. Residents, airport users, airlines, environmental organisations and other interested parties will have an opportunity to make submissions as part of the statutory process.
The Minister has indicated that he will consider the findings before deciding whether to make an Order addressing the Dublin Airport passenger cap. He will also ask the Commission to complete the assessments within the timelines established by the Act.
Why the environmental assessment matters
Any decision affecting airport passenger numbers must consider potential impacts on the environment, communities and transport networks. The assessment process is therefore intended to provide evidence before a final government decision is made.
- An environmental impact assessment report will examine relevant environmental effects.
- A Natura impact statement will consider potential implications for protected European sites.
- Public consultation will allow interested parties to contribute to the review.
- The assessment outcome will inform the Minister’s decision on a possible Order.

Airport infrastructure application assessed separately
Alongside the legislative process, daa’s planning application—referred to as the Infrastructure Application—is being assessed by Fingal County Council. The Aircraft Noise Competent Authority is also carrying out a noise assessment connected with that application.
The application seeks permission to increase the airport’s passenger cap and deliver several capacity-enhancing projects. Proposed works include new piers, additional aircraft stands and an Integrated Transport Hub.
These projects are intended to provide the facilities needed to support Ireland’s hub strategy, including growth in passenger and cargo traffic. The final pace of development will depend on the planning, environmental and regulatory processes now under way, as well as airline strategies and market demand.

What happens next?
An Coimisiún Pleanála will assess the submitted environmental documents and oversee public consultation. The Minister will then take the assessment findings into account before deciding whether to issue an Order under the Dublin Airport (Passenger Capacity) Act 2026.
The planning and noise assessments will proceed in parallel. Together, these processes will determine whether Dublin Airport can increase passenger capacity and develop the infrastructure required for longer-term expansion.
Key takeaway: The Dublin Airport passenger cap has not yet been changed. The next step is a formal environmental and public consultation process, followed by a decision from the Minister for Transport.
