Counties and cities across the state are responding to unified outrage against data centers, everywhere they are being proposed.
 

Takoma Park, MD—Three out of four Marylanders, living from the Eastern Shore to Western Maryland, now live in a county or city that has enacted a data center ban or moratorium. The wave of moratoria began in Prince George’s County in late 2025, and has quickly ballooned to include nine counties in the state, including most of the most populous counties, and Baltimore City. A full list can be found below.

Proposed data center projects are spreading fast, driving up electricity demand, threatening climate progress, straining water resources, and exposing nearby communities to more air and noise pollution. Communities without moratoria are at risk of seeing massive new facilities being built in their neighborhoods before basic safeguards are in place.

“Grassroots outrage from across the state has made it clear that a moratorium is the most reasonable course of action that can be taken right now,” said Brittany Baker, Maryland Director at CCAN Action Fund. “The playing field has quickly shifted in the last few months, which is why I expect the Maryland General Assembly will likely take a serious look at statewide moratorium bills during the 2027 session.”
