Carbon nobody counts
A big data center can burn as much electricity as a town. Where the grid still runs on gas, that means tonnes of CO₂ — quietly, every hour.

The real cost of data centers on your doorstep
Find the data centers near you. See the carbon, water and power each one costs the people around it. Report the ones we're missing.
The problem
The cost they don't put on the map
Water for cooling
Many data centers drink water to stay cool — millions of litres a year. In a dry summer, that water competes with farms and people.
Millions of litres
per year, per site.
Strain on the grid
Power grids across Europe are already tight. New AI data centers ask for huge power connections — sometimes more than whole cities nearby.
Cities' worth

What you can do
You don't have to just watch
Real steps to bring transparency, protect local water and power, and hold data center operators to account.
See what's near you
Open the map and find the data centers around your town, with their size and impact.
Report a missing one
Spotted a data center we don't show? Add it in seconds. We check it, then it appears for everyone.
Learn the real impact
Every site shows estimated carbon, water and power — with the method we used, in plain numbers.
Hold operators accountable
Open, shared data makes it harder to build in secret. Journalists and locals can ask the right questions.
Roadmap
Project progress
Phase 1Live
Data centers across Europe on the map — 30+ countries, from Portugal to Finland.
Phase 2Live
Environmental impact — power, water and carbon for every site.
Phase 3Next
Satellite AI to spot sites from above, and richer detail per site.
Get notified of new data centers
Leave your name and email — we'll let you know when new data centers are added to the map.
Frequently asked questions
Why build this?+
Data center locations aren't openly available, free to access, or easy to see on a map — especially across Europe. This project fixes that, and shows the environmental cost too.
Where does the data come from?+
Public sources: official data center maps, OpenStreetMap, and reports from people like you. Every entry is reviewed before it appears.
Can you really know the water and power use?+
Not exactly — operators rarely publish it. We estimate from a site's size using published methods, and we always prefer real, published figures when an operator shares them.
Is it free?+
Yes. The map and the data are free and open. Donations keep the servers running.
I'm a journalist — how do I reach you?+
Use the Press page. Your message comes straight to us privately. We never publish our email or phone, and we reply within 48 hours.
