Seattle Halts AI Data Center Construction: Employees, Activists, and City Council Impose One-Year Moratorium

On June 3 2026 the Seattle City Council’s Land Use and Sustainability Committee voted unanimously to impose a one-year moratorium on new large-scale AI data centers, pending city-wide regulations.

Amazon and Microsoft announced $390 billion in capital spending for 2026, with Amazon allocating $200 billion—mostly for data-center build-out—while cutting about 30,000 corporate jobs. In October 2025 five developers filed proposals for data centers that would draw roughly one-third of Seattle’s daily electricity. A May 20 hearing attracted 50+ residents, no opposition; two developers withdrew and the utility reported a surge of inquiries.

Amazon Employees for Climate Justice (AECJ) sent engineers Liesl Wigand, Patrick Schloesser and Darius Irani to the hearing. Mayor Katie Wilson, council member Eddie Lin and utility chair Debora Juarez led the response. Climate group 350 Seattle, activist Nivi Achanta and Ben Jones organized outreach.

Amazon’s spokesperson told CNBC the company has no plans for new Seattle data centers and says its existing sites exceed industry water and energy standards. Mayor Wilson said, “We were happy to move toward a moratorium, knowing there was strong public support.” Eddie Lin reported over 10,000 supportive emails. Utility chair Debora Juarez warned the projected water draw could threaten tribal treaty rights.

AECJ engineers demanded renewable-energy sourcing, new taxes to fund city jobs after layoffs, and safety committees reporting to the city. Wigand warned that “Big Tech” would “burn Seattle” to win the AI race; Schloesser stressed the need for “good jobs” and tax contributions. Ben Jones said residents lack a voice on AI rollout, and Achanta noted tech concentration makes collective backlash easier.

• “Let’s not let Big Tech burn Seattle to win the AI race.” — Liesl Wigand, Senior Software Engineer, Amazon

• “You've got to provide good jobs building these things, and you've got to pay a new tax that funds city jobs every time you conduct a large layoff,” — Patrick Schloesser, AWS Engineer

• “I do think the consolidation of these large tech companies makes it easier to find the backlash, and to see very easily that you’re not alone,” — Nivi Achanta, Climate Activist

The Guardian

• “If we’re able to show that we say no to it in Seattle, where you would assume it might be more techy, I think that will hopefully set precedent for the rest of the state, potentially the rest of the country,” — Audrey Wang Gosselin, Board Member, 350 Seattle

The Guardian

Seattle will use the moratorium year to draft sector-specific regulations on pollution limits, energy-connection standards, and public-benefit requirements such as affordable-housing contributions. The city plans to lobby the Washington state legislature for statewide data-center oversight, while activist networks aim to replicate Seattle’s model in other jurisdictions.
