40 mayors worldwide endorse a pact to shape data center development
The pact seeks clean energy use and tighter planning as AI-driven data centre demand strains grids, water supplies and communities, Reuters said.
On Tuesday, mayors from 40 cities, including London, Phoenix, and Melbourne, launched The Global Urban Data Centres Pact at London Climate Action Week to curb strain on electricity grids and water supplies.
Melbourne Lord Mayor Nicholas Reece warned that investment is occurring at "breakneck speed," leaving cities at risk of a "race to the bottom" as governments compete for investment by bypassing environmental scrutiny.
Phoenix Mayor Kate Gallego reported 225 existing or planned data centers, while Melbourne anticipates consuming 20 billion liters of water annually for a city of 5.5 million people.
Coordinated by C40 Cities, the pact provides a framework to guide permitting and planning decisions, ensuring developers use renewable energy and build on underutilized land.
As AI-related computing needs drive global investment, data centers are projected to account for 10% of local power demand by 2030 and 20% by 2040 across Asia-Pacific and other regions.
