Amazon's own workers are pushing back against their employer's data center expansion plans, with current employees joining dozens of residents in calling on the Seattle City Council to halt new projects for a year. The council is set to vote Tuesday on a proposed moratorium that would pause any new large-scale data center proposals in Seattle for 12 months, giving the city time to draft legislation addressing the rapidly growing facilities. The push comes just two months after several companies proposed building five massive data centers in Seattle and surrounding King County, where concerns about water consumption, rising electricity prices, and noise pollution have sparked protests nationwide. At two city council hearings last week, testimony ran overwhelmingly in favor of the moratorium, including from engineers, software developers, and other tech industry professionals. Among them was Liesl Wigand, a senior software engineer at Amazon, who told the Seattle Land Use and Sustainability committee that her job gives her a clear view of "the consequences of the all-costs-justified AI buildout." Wigand argued that a prevailing belief that AI should solve every problem has overshadowed the resources required to power the technology, a culture she described as "omnipresent across tech." She is a member of Amazon Employees for Climate Justice, a coalition of current and former Amazon staff focused on the climate crisis. The internal dissent reflects a broader rift within Amazon over its AI ambitions. Last year, more than 1,000 Amazon employees signed an open letter accusing the company of "casting aside its climate goals to build AI," a direct challenge to leadership's push to scale up infrastructure to support artificial intelligence workloads. The Seattle vote represents one of the most concrete local efforts yet to slow that expansion, with residents and tech workers alike framing the moratorium as a chance for the city to reclaim control over how data centers are built and operated. If approved, the pause would freeze new proposals while Seattle weighs rules on everything from energy use to water draw.
