Forty mayors sign pact to shape how data centres grow in cities
A C40 Cities agreement aims to guide the rapid build-out of AI infrastructure amid mounting concern over power demand, water use and the strain on local communities.

Forty mayors have endorsed a C40 Cities pact intended to shape how data centres are built and run in urban areas, a response to rising anxiety over the resources these vast facilities consume and the pressures they place on local communities.
The agreement reflects a growing recognition that the breakneck expansion of artificial-intelligence infrastructure cannot proceed without regard for power demand, water use, land availability and the climate commitments cities have made.
Why cities are acting
Data centres are the unglamorous backbone of the AI boom, and their hunger for electricity and cooling water has turned them into a flashpoint in local politics. Mayors are increasingly caught between the lure of investment and jobs and the strain on grids, water supplies and emissions targets.
- Forty mayors have signed the C40 Cities pact.
- It seeks to guide how data centres are built and operated.
- Concerns include power demand, water use and land pressure.
- The deal weighs local jobs against climate commitments.
Balancing growth and sustainability
The central tension is whether AI infrastructure can keep expanding without undermining the environmental goals cities have set. The pact suggests a willingness to set shared expectations on efficiency, transparency and community benefit rather than leaving each development to be negotiated in isolation.
“We want the benefits of this technology without sacrificing our water, our grids or our climate targets.”
Background
C40 is a network of major cities committed to tackling climate change, and its members have often used collective pledges to push standards beyond what national policy requires. The surge in demand for computing power has pushed data centres up the agenda for urban leaders worldwide.
What happens next: attention will turn to how the commitments are implemented, with the credibility of the pact resting on whether signatory cities translate shared principles into concrete planning, efficiency and transparency requirements for developers.
