Once more for those in the back - Metrolink is not only an airport line

It serves 15 other stations, connecting 127 schools, 3 universities, 5 hospitals, and making over 175k people and 250k jobs accessible by foot to a stop. An estimated 18% of passengers will use airport stop

77% of NDP review submissions prioritised transport investment (low response rate)

Metrolink's โ‚ฌ2bn funding & support will see the project start construction, pending planning permission

But the devil is in the detail, how will the rest of the โ‚ฌ20bn be spent ..roads vs pt?

"At the end of 2024, there were just over 82,400 battery electric (BEVs) and over 66,500 plug-in hybrid
electric (PHEVs) vehicles in Ireland, approximately 76% of the Climate Action Plan target for 2025 of
195,300 or 16% of the 2030 policy target of 941,500 vehicles." page 18 of the report

New results from the @epaireland.bsky.social show our transport emissions are down 1.2%, given we have missed the target for a number of years now we are very far behind the 2030 target.. The report says EV sales have very little to do with he drop due to the low number

Future of the Luas: suburban routes and circular services around Dublin by 2050 Work on new lines should begin every one or two years to build tram network fit for future, transport officials say

This would be a game changer for the city, but it has taken 30+ years to deliver 45km of Luas, this map has 85km+ of new lines.. the pace of delivery will have to exponentially increase to deliver this plan in 25 years.. we last opened a new line in 2017

No, they would use the TII car stock model which has built in fleet turn over to EV. They dont make sweeping assumptions that all vehicles will be electric in x years time

Is there not some sort of national guidance on how to do these assessments? In transport we have a very detailed approach

A5 campaigners 'deeply disappointed' by court decision Campaigners say they are "deeply disappointed" by a decision by a Belfast court to quash a Stormont decision to approve a huge roads scheme in Northern Ireland.

"Mr Justice McAlinden ruled in favour of those who had brought the challenge.

He said there had not been sufficient scrutiny of the method of calculating greenhouse gas emissions from the new road."
