Minister for Justice Charlie Flanagan has said the new runway at Dublin airport is 'warranted and needed' despite concerns about climate change.
The minister was asked about plans for expansion of the capacity at the airport given the recent declaration of a climate emergency by Dáil Éireann.
He said that new facilities at the airport are planned under Ireland 2040 which has been approved by the Oireachtas.
He was speaking at the opening of the new e-gates for passport control at Dublin Airport.
These latest e-gates feature flatbed scanners which will allow passengers to use passport cards.
They are operating for arrivals in Terminal 1 and will soon be operational in Terminal 2.
Dublin Airport is continuing operation of staffed booths and the e-gates have been introduced to help deal with increasing numbers coming through the terminals.
In 2018 there were more 2.5 million passenger arrivals through the e-gates; around 16% of the annual total.
The e-gates use facial recognition technology and are connected to national and international watch lists.
