Mayor Brandon Johnson has signed an executive order to intensify the scrutiny of new data centers in Chicago. While this move doesn’t impose outright restrictions, it seeks to regulate the fast-growing industry by toughening air pollution evaluations, adding noise restrictions, and allowing city officials more authority over water and electricity use reviews in data centers.
The order does not outright ban or cap new construction. Johnson urged the City Council to pass a moratorium on new data center projects until more comprehensive rules are developed. At a news conference, Johnson emphasized the need to get ahead of the trend, arguing for a temporary moratorium to prevent unchecked development of data centers without strong protections.
Johnson stated, “Chicago will not be passively shaped by this new industry. We will lead and actively set the terms.” The order is the city’s most robust response to issues associated with these facilities, such as noise, pollution, and resource consumption. Aldermen are set to consider a proposed ordinance requiring data centers to report water and electricity usage. This aligns with the new executive order and aims to provide greater transparency.
The move reflects a broader national trend. Over 530 municipalities have restricted data centers, with more considering similar measures. In Illinois, some towns have canceled or restricted data center projects. Several aldermen supported Johnson at the announcement, a move that shows rare unity given his sometimes strained relations with the council.
During his remarks, Johnson called on state legislators to regulate larger data centers, often located outside the city. He defended the order as a means to protect local resources and prioritize residents over unchecked development. “Development cannot happen at the expense of working people,” Johnson stated.
Currently, Chicago hosts 39 data centers, with more planned to meet growing demand. The Sustainable Data Centers Working Group, formed by the city, highlights that these centers can spike electricity costs and challenge climate goals.
The move received praise from environmental advocates. Iyana Simba of the Illinois Environmental Council noted that data centers can increase bills, strain utilities, and impact community health. Action at all government levels is deemed necessary.
Johnson’s announcement on Northerly Island, a site converted from a downtown airport to a nature sanctuary, underscored the city’s capability to prioritize sustainable growth. Angela Tovar of the Department of Environment highlighted the island’s transformation as inspiration for Chicago’s approach to future development.
