Mayor Brandon Johnson signed an executive order on Tuesday aimed at increasing oversight of new data centers in Chicago. This move seeks to scrutinize the industry without imposing direct limits but could slow its growth.
The order mandates city departments to enhance air pollution checks, implement noise restrictions, and extend the review of water and electricity usage in data centers. However, it does not stop or limit new construction. A halt would need City Council’s approval, which Johnson urged during the announcement to consider a temporary stop on new projects.
“This is a newer phenomenon, and we want to get as out front of this matter as fast as we possibly can,” Johnson said. “A temporary moratorium is critical because it will ensure that new data centers do not move forward while the City Council contemplates the deliberate, comprehensive process of developing the protections Chicagoans have called for and deserve.”
During a news conference, Johnson emphasized the importance of considering Chicagoans first as the city forms its stance on the industry, driven by artificial intelligence and cloud computing growth.
“Chicago will not be passively shaped by this new industry. We will lead and actively set the terms for how this technological development occurs,” Johnson said. “Chicagoans have been absolutely clear: They do not want data centers expanding across our city without strong protection.”
The order signifies Chicago’s firm stance against the challenges posed by data centers, known for disruptive noise, pollution, and excessive use of water and electricity. Aldermen are set to review an ordinance next month, introduced by City Council Environmental Chair Ald. Maria Harden, that mandates data centers to disclose their utility consumption.
Hadden stated her proposal complements the mayor’s order. Other officials joined Johnson, showcasing support despite occasional friction between the mayor and the council. Johnson’s joke about an alderman having his back highlighted this complex relationship.
The mayor urged state legislators to pass the POWER Act, targeting regulations on large-scale data centers, potentially situated beyond city borders. When questioned about economic implications, Johnson prioritized environmental protection, including safeguarding access to the Great Lakes.
Chicago currently hosts 39 data centers, with plans for more due to increasing demand. One proposal aims to develop a center at 300 W. Adams St., a landmarked site designed by Jens Jensen.
Johnson’s order aligns with recommendations from the city’s Sustainable Data Centers Working Group. The panel has cautioned against rising electricity costs and potential setbacks to climate goals tied to data centers.
“Our electric bills have already gone up because of data centers and will continue to do so unless policymakers at multiple levels take action,” said Sarah Moskowitz, executive director of the Citizens Utility Board.
Environmental activists, including Iyana Simba from the Illinois Environmental Council, supported Johnson’s decision amid concerns about grid reliability, air pollution, and compromised community health due to AI-driven data centers.
Angela Tovar, commissioner of the Department of Environment, spoke at the news conference on Northerly Island, a location transformed into a public park from Meigs Field runway. This symbolism highlighted Chicago’s ability to prioritize environmental well-being.
“That’s exactly the spirit we’re bringing to the work we are here to talk about,” Tovar said, emphasizing prioritizing nature and health over previous constructions.
