Climate Action Committee [Draft]

Environmental Impacts of Hyperscale Data Centres

Meeting date: 5 November 2026

James Adams

Wim, in your written submission, you note:

“Data centres require cooling. If a river or canal is used as a source for evaporation cooling, surface water quality will be affected because the water level will drop.”

Alternatively,

“If groundwater is pumped locally, this will very likely lower the water table.”

Earlier, you noted that the water usage of hyperscale data centres is a bit of a “red herring”. Can you clarify how we should assess the potential impact of hyperscale data centres on national and local water resources in Scotland?

You mentioned the trade-offs. Can you give us a bit more detail about what relationship exists between the cooling technologies and energy efficiencies with regard to water use? I am relatively new to this subject. If water use is mitigated and goes down, what else happens? Does energy consumption go up?

Environmental Impacts of Hyperscale Data Centres

Meeting date: 5 November 2026

James Adams

Good morning. Andrew Weir, in your written submission you note that Scotland’s cooler climate, paired with appropriate cooling designs, could potentially

“offer a competitive water-efficiency advantage”

for data centres in Scotland. With that in mind, how do you assess the impact, or the potential impact, of hyperscale data centres on water resources in Scotland, both nationally and at a local catchment level? How can high levels of water usage potentially be mitigated?

Alejandro, do you have any additional points to make?

When I speak to members of the public in the north-east of Scotland, they tell me that they are concerned about the environmental impact of proposed hyperscale data centres on water use. What information on energy use, water use and environmental performance should data centre operators be expected to report publicly?

Yes.

How easy is it for data centre operators to estimate that for the lifetime of such projects?

Thomas and Alejandro, do you have anything to add?

I assume that waste water would have to be treated or cleaned before it was used for cooling. What that add to the emissions load for the project?
