Climate Action Committee [Draft]

Environmental Impacts of Hyperscale Data Centres

Meeting date: 29 October 2026

Stuart McMillan

Agenda item 2 is the first in a series of evidence sessions as part of the committee’s inquiry into the environmental impacts of hyperscale data centres.

Before I introduce our witnesses, I will say a few words about the inquiry, our approach to which the committee agreed on 17 September and 1 October. Our aim is to find out about the environmental impacts of the operation and construction of hyperscale data centres in Scotland. We will look at aspects such as water consumption, air quality, noise pollution and energy use, including for any back-up generation. We are also interested in the impact of growth in the sector on Scotland’s ability to meet its carbon budgets and how it will affect the climate change plan. Specifically, we want to know what systems should be put in place to mitigate any negative impacts on the environment, as well as what Scotland can learn from other countries.

We will gather information in three ways. First, the committee is collaborating with the Economy, Tourism and Energy Committee to run a call for views. I encourage people to share their views on the issue with us. Details can be found on the committee’s website.

Secondly, members of the committee recently visited a data centre in North Lanarkshire. A visit to the DV1 site, which is run by DataVita, allowed members to see how a data centre operates.

Thirdly, we will take evidence from experts across three meetings. In the coming weeks, the committee plans to take evidence from witnesses with expertise in the technology sector, sustainability, emissions and heat. Today, we will hear from a panel of witnesses with environmental backgrounds, after which we will take evidence from a second panel on the experience of data centre development in Ireland.

Before we do that, I emphasise at the start of our inquiry that the committee wishes to understand more about the environmental impact of data centres. At this stage, we are gathering information that will be shared with the Scottish Government in advance of its producing national planning guidance. In other words, we are not engaging in the scrutiny of individual planning applications, which are a matter for local authorities.

I welcome our first panel: Kat Jones is the director of Action to Protect Rural Scotland, and Kim Pratt is a senior campaigner at Friends of the Earth Scotland. Thank you for your engagement with the committee.

Colleagues have quite a number of questions, but I will begin with a couple of quick ones. First, should we have data centres in Scotland? Secondly, should we have hyperscale data centres in Scotland?

Subordinate Legislation

Meeting date: 29 October 2026

Stuart McMillan

Agenda item 3 is consideration of a Scottish statutory instrument. The instrument is laid under the negative procedure, which means that its provisions will come into force on the specified date unless the Parliament agrees to a motion to annul it. No motions to annul have been lodged.

Do members have any comments on the instrument? As there are no comments, do members agree that they do not wish to make any further recommendations in relation to the instrument?

Members indicated agreement.

Thank you. I will move to James Adams, but, first, I ask the witnesses to try to keep their answers a bit shorter, please, if possible, because we are really struggling for time. Thank you.

I am conscious of the time. I will bring in Ronan Kelly briefly on one point, and then we will move on.

Thank you. I am conscious that I am over time with my questions, but I will ask one more. What would a responsible hyperscale data centre actually look like?

I welcome to the committee our second panel of witnesses, who join us online: Professor Hannah Daly, professor in sustainable energy, University College Cork; Ronan Kelly, chief executive officer, Digital Infrastructure Ireland; and Rosi Leonard, data centre campaign lead, Friends of the Earth Ireland.

Thank you very much for joining us today and taking part in our inquiry. I also thank you for your patience, as the first panel overran slightly.

We have a range of questions. First, can you tell us about the history of the development of hyperscale data centres in Ireland? When did the developments begin to arrive, and what is the current state of affairs?
