A coalition of about 40 mayors from cities in different countries has formed to push back against the rapid expansion of AI-related data centres. According to reports, the mayors say the construction and operation of these facilities are straining local resources, including electricity supply, water availability and land use, while also contributing to higher costs for local power systems.

The campaign is described as coordinated across multiple cities, with examples ranging from Phoenix to Melbourne. The mayors argue that the pace and scale of Big Tech’s AI buildout creates governance and infrastructure challenges that local authorities are not adequately equipped to address on their own. They call for stronger collective action and new approaches to negotiations with data centre developers.

One outlet also raises the question of whether mechanisms such as collective bargaining could help cities secure more favorable terms or mitigation measures. Overall, the sources portray the mayors’ effort as an attempt to coordinate their leverage and priorities in response to increased demand driven by AI computing, while seeking practical changes to reduce local impacts.
