Background
Ecologistas en Acción is Spain's principal environmental NGO confederation, a network of around 300 local groups federated under a single national structure. In April 2026 it led the legal Coalition that filed Spain's first data centre lawsuit at the Tribunal Superior de Justicia de Aragón (TSJ Aragón), challenging Amazon Web Services' 30-building data centre campus in the Aragón region on grounds including water consumption, electricity demand, and the use of a Programme of General Interest planning instrument that critics say bypasses normal environmental review.
The Aragón campus is Spain's largest planned data centre cluster, spanning locations including Zaragoza, Villanueva de Gállego, and El Burgo de Ebro. Ecologistas en Acción has argued that the scale of water cooling demand — in an already water-stressed region — was not adequately assessed in the planning process, and that the concentration of power demand will strain the Aragonese grid.
The organisation has been active in Spanish environmental politics since 1998 when it merged several predecessor groups. Its litigation strategy has previously targeted infrastructure projects including airports and highways. The data centre case represents the first time the organisation has deployed its legal resources against digital infrastructure, marking a broader shift in European environmental advocacy.
