Climate Action Committee [Draft]

Environmental Impacts of Hyperscale Data Centres

Meeting date: 29 October 2026

Claire Baker

I will try to unpack some of this.

We have to consider why we are having data centre expansion in the UK. Governments will argue that most of our data is not held in the UK, so essential data, whether it relates to defence, health or other things that we value, is not stored within the UK. We do not have the capacity to keep it here. Other nations have expanded their data capacity, so we are potentially at the mercy of other countries that hold our data. Therefore, our Governments will argue that there is a need to expand our capacity within the UK.

You can be critical of the UK Government’s position if you want to be, but it has a strategy in place. You might disagree with its strategic approach, but at least there is one. In Scotland, as you mentioned, we have a number of active applications but there is no such approach.

The Scottish Government has committed to creating planning and spatial guidance by the end of the year. Kat Jones, you said that that timescale is challenging. Do you have confidence that the Government can do that in that time? If you think that the Government is going to approve or create some kind of plan that will allow the development of data centres in Scotland, what safeguards would you like to see in the updated guidance?

Environmental Impacts of Hyperscale Data Centres

You mentioned the lack of consultation with communities. You referred to the letter that we got back from the minister, which talked in broad terms but did not give a direct route for communities to engage. Have your organisations had any discussions with the Government?

If the Government decides to approve data centres in Scotland, or if it gives a mechanism for them to be approved, that will have an impact on our carbon emissions. Judging the carbon emissions is not built into the planning. Therefore, what would development in that area mean for the carbon targets that we are currently working with? Has the Government engaged with you on that?

Finally, I think that Hannah Daly talked about restricting centres to additional renewables, but surely that would be impossible, as it would mean no development of data centres. Would it not be extremely challenging, if not impossible, to produce the energy that is needed for a centre just from additional renewables? Could you respond to that question, Professor Daly, and to the other question about noise and other impacts on communities?

The Scottish Government has said that it would promote green data centres, but we do not have any definition of that. I assume that your example demonstrates what a green data centre could be. Is there anything else that would be included in the description of a green data centre?

The committee has undertaken an inquiry because there are 23 or 24 live planning applications for data centres in Scotland. Our remit is to consider the environmental impact in advance of the Scottish Government’s issuing of fresh guidance, which it has committed to provide by the end of the year. We want to influence that guidance.

I am particularly interested in the impact on people who live near data centres in Ireland. Noise pollution is one of the issues that has been raised, but Rosi Leonard mentioned air quality and other issues. Does your organisation have an idea of the impacts on people who live close to data centres?

Kim Pratt has set out the impact. Could it be mitigated?

The Government has previously argued that it is for local authorities to make decisions and that it will be criticised if it starts to give central direction. Do you agree with that? How can you deliver a strategic view when local authorities will make decisions?

I have a final question about one of the aspects that constituents are concerned about, which is noise pollution. Do we have an understanding of what impact the noise from hyperscale data centres would have on local communities?

You said that the noise issue with one of the data centres has been particularly problematic and is being investigated, but other data centres have not produced the same concerns about noise levels. On energy constraints, the issue is not that people are losing their energy supply but that there could be constraints on future developments that would involve energy. Is that correct?

Mr Kelly, you can respond to the question on community impact, too, but the question that I have that might be more suited to you is on how Ireland made its decisions and what kind of trade-offs were involved. Electricity constraints have been mentioned, as well as the use of land for agricultural purposes rather than for data centres. Did that come into the discussion that was had in Ireland on its plan? Did people think, “Well, if we have a data centre, it compromises other things that we could do, so there will have to be trade-offs”? Was that part of the thinking or considered in the discussions?
