Chicago Mayor Brandon Johnson proposes a 12-month data center expansion moratorium

On Sep 23 2026, Chicago Mayor Brandon Johnson proposed a City Council ordinance for a 12-month moratorium on new data center development so the city can write longer-term rules on pollution, water use, electricity costs, noise, and air quality. The measure follows an August 2026 executive order that intensified scrutiny and stood up a city task force.

Cosponsored by Alds. Maria Hadden (49th), Lamont Robinson (4th), and Leni Manaa-Hoppenworth (48th). Chicago Tribune reports the proposal was introduced the same day; parliamentary delays later stalled committee referral.

Proposal only; not an enacted ban. Industry group Data Center Coalition opposed. Local press + mayor statement.
