Landesamt für Umwelt Brandenburg

Brandenburg's state environment agency is based in Potsdam, with further offices in Frankfurt (Oder) and Cottbus, and has carried its current name since 2016. It enforces the Federal Immission Control Act and Brandenburg's own immission control law, serves as the state's upper water authority for flood protection, and advises ministries and district authorities on water, pollution control, Nature conservation and soil protection.

Its data-centre caseload includes Trebbin. Two buildings and a substation went up under building permits, the town said on 7 October 2026, while the agency's review of the operating permit stayed open. In June 2025 the agency had logged an application there under section 4 covering 24 diesel emergency engines plus a life-safety generator, up to 187 MW of thermal input in all, and judged that no full environmental impact assessment was needed.

Building permits let the structures rise; only the agency's permit lets the site operate, so its conditions will apply to buildings already standing. Brussels adds another layer: the Commission approved energy grades from A to G for large EU sites in September 2026.
