A classic political fudge.

We've become accustomed to seeing National Development Plans heralding long wishlists of projects but this Government can’t even fully agree to back the aspirations in this plan.

The big point of contention is road projects.

That has been clear from yo-yoing headlines over the past few days on whether the plan will back roads or not.

There is a clear line between Fianna Fáil and Fine Gael on one side and the Green Party on the other.

To fudge the ideological divergence, the plan contains a list of road projects to satisfy the two larger coalition parties but the Green Party leader Eamon Ryan was able to say there is no guarantee these will be built.

That’s because the plan is framed within the key Programme for Government commitment that investment in public transport versus roads would be done on a 2:1 ratio.

Pressed on whether the roads listed would go ahead, Taoiseach Micheál Martin said they would, adding that delivery is key but he stopped short of offering an absolute guarantee.

Mr Ryan explicitly said there was no guarantee they would all go ahead.

So which is it?

There are no new roads in this NDP compared with the previous one three years ago.

There are three projects listed as definitely going ahead with construction likely to begin in six months.

These are the N5 Ballaghaderreen to Scramoge, the N59 Moycullen bypass and the N69 Listowel bypass.

Everything other than those three projects is merely at the proposed stage. This is a long list of 31 roads including the M20 Cork to Limerick motorway and the Galway ring road.

Green Party spokesperson on Transport, Climate Action and Environment Brian Leddin said the proposed roads would compete with each other for funding at a time of transition away from private car ownership.

Translation: many won’t get built.

And while that was the case with previous plans, this is the first time the admission has been made so freely.

Take the long-heralded Cork to Limerick Motorway - the M20.

It has undergone a small but significant renaming in the plan to become the "N/M20" – an indication that it won’t be full motorway all the way. Lower speeds mean lower emissions albeit with longer journey times.

Countering this, Junior Fine Gael Minister Peter Burke said if a road project was listed, then the ambition was there to carry it out but he conceded that all will have to undergo assessment.

The classic fudge does not please everyone. Oisín Coughlan of Friends of the Earth said it does not resolve the struggle between the two competing elements of the Programme for Government adding that governing is about making choices.

But the compromise does ensure both sides can sell a win to their constituencies and that is undoubtedly at the heart of coalition politics.

The opposition were not buying it though.

Labour’s Ged Nash said this had all the hallmarks of a "political ready-up".

"The idea that Fine Gael and Fianna Fail backbenchers could be bought off by a roads programme that might ultimately not be delivered is some hustle," he said. "It is an insult to the intelligence of the Irish people and goes to the heart of the credibility problem of this slick, repackaged but hopelessly vague plan."

For the Greens, the climate-proofing of the document is a real win.

For the first time, the plan is benchmarked against climate and environmental standards and it appears to be the greenest ever National Development Plan.

But while the Greens may have scored a win on roads, there are only vague commitment to some large-scale rail developments.

Once again, Metrolink and Dart extensions make the cut but without detailed costings or timelines.

They are marooned in the waiting room.
