Mr. George Hussey:

I will start and Ms Gallagher can come in with more detail. We do not have a single model that can do all of this work for us. We are reliant on the expertise coming in from across the sectors. We have considerable expertise on the energy side coming in from UCC and considerable expertise on land use change coming in from our colleagues in Galway. Teagasc is also heavily involved in the process. We had a number of iterations. We asked them to do this more than once so that we could feed back what it looked like to the council, get feedback from the council, give it back to them and so on. The main work of the working group was the delivery of a suite of modelling outputs. We then brought in external expertise from UCD to do the work on the temperature neutrality that Ms Donnelly and Ms Gallagher have already spoken about.

The group met on 18 occasions. It contained expertise from a variety of other areas including - I will not capture everybody here - people from the biodiversity, climate justice and just transition sides, as well as from the EPA, which has a significant role. We need to take careful account of the EPA data, inventories and projections. I am sure I have forgotten somebody and I apologise to them, whoever they are. The SEAI was also deeply involved and was able to look at the outputs of one model and provide feedback. Similarly, the NTA was able to look at the outputs of the energy model and give its feedback. There is an incredible wealth of experience from both within and outside the government system. Most of it is from within but some comes from academia. They were brought together to deliver over 1,000 scenarios that our expert on the temperature neutrality side was then able to apply his modelling to in order to work out where they fit in terms of the temperature neutrality. That does not really do justice to the thing at all. Ms Gallagher might like to add a few comments.
