The Wrong Variable
Run a hyperscale data centre through a lender's environmental and social screen. Answer every question honestly. It comes back clean, and the answer is correct. Then look at what the screen never asked.
For people who set and apply environmental and social standards. It characterises a facility class and describes no particular transaction.
Safeguard frameworks size social impact by footprint, land take, workforce and receptors at the boundary. This asset is thin on all four.
Screen it yourself
Six questions, in the substance the standards actually ask. Answer as an honest officer would for a hyperscale campus on a serviced industrial lot.
Nothing on that form was answered wrongly, and nothing about it was hidden.
A reviewer reading that file finds no error, because there is none in it. Now ask the question the form does not contain: what will it draw, from a system other people are already queuing on?
The question that is not on the form
What the facility will draw from the municipal systems, and who else is drawing on the same ones. Set the numbers to whatever you think is realistic.
Each approved on its own, each correctly.
What the six of them want, together
And the same question about water
One variable decides this answer, and it moves it by three orders of magnitude.
| Cooling design | Litres per kWh | Megalitres a year | Households' annual water |
|---|
All six facilities together, at each design. The row in bold is the one selected above. An application that does not state its cooling design leaves every row of this table open.
The conversion, and every coefficient in it
A connection is sized in MVA. The running load in MW is a little less.
The share of the connection actually drawn, around the clock. This class runs high and flat.
An ordinary urban household. Replace it with your city's figure.
Total facility energy over IT energy. Water intensity is quoted per kWh of IT energy, so this matters.
An ordinary urban household. Varies widely by city and tariff block. Replace it with your municipality's.
Used only for the restriction comparison.
Water intensities: closed loop and direct liquid with dry coolers, zero. Best in class hybrid, 0.26 to 0.30 litres per kWh. Adiabatic or hybrid, 0.2 to 0.8. Full evaporative, 1.8 to 4.0. These are published industry ranges, not figures from any application.
Households are a unit of comparison, not a claim that households are cut off to serve a facility. The point is scale: how much of a shared system one building commits, in terms a person can picture. A number you cannot interrogate is not evidence, so all three are yours to change.
Processes, anywhere, that add up this column
0
Not an oversight by anyone. Each application is assessed on its own site, correctly, against the headroom that one file was shown. No door, no tribunal, no lender and no register is given the total, so the trade-off it implies is never actually made by anybody. The international sector guidance published in June 2026 names cumulative pressure as a consideration and provides no aggregation instrument either.
Why this is not the usual complaint
The figures were due later
In the jurisdiction studied here the resource figures were not withheld. They were not yet due, on a schedule written for a building this is not, and the due date fell after the decision they were material to. That is a stranger problem than concealment, and a harder one to fix.
Better reports change nothing
The question set every downstream specialist inherits is fixed at classification, before anyone opens a file. Improve the studies and you improve answers to questions that were never going to reach the draw.
Where the sector instrument sits
The Equator Principles Association published sector guidance in June 2026, developed with Arup, and it closes a good deal of this. It asks whether cooling is evaporative or adiabatic and, where it is, whether water scarcity has been assessed at the level of the region and the local catchment. It requires water use effectiveness annualised and at peak, read together with power use effectiveness rather than instead of it. Associated facilities are handled properly, down to substations, transmission, water supply and on-site treatment, and the guidance states in its own words that the direct footprint of a data centre is often modest compared with the extensive external systems required, which is the asymmetry at the top of this page, in their words. It names competition for water resources in water-stressed contexts. It names indirect and cumulative pressure on systems with constrained capacity. Anyone financing this class under the Equator Principles now has a document that asks most of the right questions about a single transaction.
Read end to end, it also names grid pressure twice, in the screening criteria and again on the burden falling to municipal systems. Every appearance is a question about the project in front of the reader: a threshold for one transaction, a benchmark set in line with industry and regional expectations. Nothing asks whether the system can still serve the next applicant, which is the question the households on the same feeder are living inside, and which the panel above is an attempt to make answerable.
Three questions the guidance does not ask
Raised here because in an instrument still being drafted these are choices available to the drafters, rather than omissions to be complained about after the fact.
One
Efficiency is not allocation
The guidance names system pressure, in its Category C screen and its community section, but every one of those is a question about one project alone, and its WUE question is a benchmark: in line with industry and regional expectations or targets. Nothing asks whether the system can still serve the next applicant. An EHS Guideline is structurally built around performance benchmarks, so the shape of the instrument may itself not fit an allocation impact.
Two
Nothing aggregates across facilities
Cumulative pressure is named as a consideration, on a context-specific basis, for one project's assessment. No instrument tells anyone to add up the column across facilities on one system. Each transaction is assessed correctly and alone.
Three
The benefit case is not tested
The guidance is risk-side throughout, which is right for its purpose. But employment and skills claims are what these projects are approved on locally, and nothing asks whether those claims are written in a form that could be shown to have been missed.
The working behind all of it
Everything above is derived from a published corpus rather than asserted. These run in a browser, send nothing anywhere, and show their coefficients so the arithmetic can be argued with.
