![According to Irish Water, as of 2021, data centres across Ireland drank about 810 megalitres of water from the public mains a year – which is about 0.13 percent of overall national supply.
But that same year, Meta reported that it withdrew 928 megalitres of water for its data centres in Clonee in Meath. Planning documents say that it was to rely on water from the mains.
That’s more than Irish Water said was consumed overall in the country that year.
A spokesperson for Irish Water said on 19 June [2026] that it couldn’t lay out its methodology behind the 810 megalitres figure – or give more up-to-date figures on water use by data centres, since the AI boom.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:sjznb6msdsbogkbwdorupxz3/bafkreia6pcrfbgpds4s7waaniamogy73earjmu3xzts4mlbj6cet57i4pa)

![Screenshot of Figure 4 from "Carbon Budgets Working Group Outputs Report", Climate Change Advisory Council, 2024, showing alternative Ireland scenarios for 2020-2100 with agricultural non-CO2 (methane and nitrous oxide) mitigation effort increasing from left to right. Scenarios with a blue vertical bar reach climate neutrality [= temperature neutrality] by 2050. In all cases, net zero CO2 occurs in 2043 with 2021–2050 emissions of 440 Mt.
– However, the neutrality outcome temperature levels are different from different scenarios so the neutrality gauge is ambiguous. Moreover, given our and CCAC previous research it is likely that many of the neutrality outcomes are reached in overshoot of a fair share 1.5ºC level, therefore they fail a Paris Test, so Irish climate ambition is likely weakened by using a neutrality framing.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:6lpspwgxnxbrzgomcwnfos7u/bafkreidgtusjzvmzluufitpvdhu546bbd5l6xzogiohmoqnaq5azgjxpnq)
