The city of Seattle has enacted a year-long pause on the establishment of new datacenters, with the city council voting unanimously to implement this temporary measure on Tuesday. This decision positions Seattle as the largest city in the United States to adopt such a ban amid growing concerns over infrastructure for artificial intelligence (AI).
As a significant technology hub that hosts major companies like Amazon and Microsoft, Seattle is responding to increasing public opposition to the energy-intensive datacenters that are proliferating across the country. City officials view this moratorium as a crucial opportunity to formulate regulations specifically aimed at these facilities, which are notorious for their substantial electricity consumption. The goal is to safeguard residents from potential environmental hazards and rising utility costs.
Mayor Katie Wilson emphasized that this pause will enable her administration to assess whether datacenters represent a suitable use of urban space. There is also potential for imposing new requirements on future datacenter approvals, such as mandating that developers invest in local transportation and housing initiatives in exchange for the necessary permits.
Wilson indicated that public pressure has played a significant role in driving this decision, stating, "There are times when public pressure forces elected officials to do something they don’t want to do, but in other cases, public pressure just supports and helps to spur on elected officials to do things that they already want to do. I think this was one of those latter cases."
The decision to impose a moratorium followed a report by the Seattle Times that five forthcoming datacenter projects could account for nearly a third of the city’s current electricity demand. In response, local tech workers, including groups like Amazon Employees for Climate Justice, engaged with lawmakers and conducted a letter-writing effort that yielded almost 100,000 emails opposing the datacenter developments.
Ben Jones, a representative for the climate-advocacy group 350 Seattle, noted that a significant number of tech professionals voiced their concerns about the impact of AI on job security. This apprehension is exacerbated by the recent layoffs of thousands of local workers at Amazon and Microsoft, which are on track to invest approximately $390 billion in AI by 2026.
An amendment to the moratorium, passed unanimously last week, permits existing datacenters in Seattle to seek expansion for up to 20 megawatts of additional power during the moratorium. Activists have raised alarms that this provision could increase overall power demand from datacenters during the temporary pause, potentially undermining the initial intent of the moratorium.
Lawmakers defended this amendment as a means to distinguish between existing datacenters with civic importance—such as those serving healthcare facilities and emergency services—and newly proposed large-scale centers catering to the AI industry.
Seattle’s activists are collaborating with various organizations throughout Washington state to coordinate similar campaigns against datacenter projects, extending their efforts to cities like Spokane and Walla Walla.
Looking ahead, Mayor Wilson announced her administration's intention to advocate for new regulations governing datacenters at the state level during the upcoming legislative session in Washington.
