Data Centres: Boom and Backlash: Spain's first DC lawsuit lands at TSJ AragónBackground
Ecologistas en Acción is a Spanish environmental confederation that brings local campaigns together under a national organisation. Its work spans environmental harms and infrastructure policy, with litigation used when campaigners believe public scrutiny or environmental assessment has fallen short.
Its data-centre role centres on the Aragón challenge announced in January 2026 and recorded as filed in April. The case contests the planning route used for Amazon Web Services' expansion and raises water, power and environmental-review questions. The Programme of General Interest provides a strategic route for large projects. Ecologistas en Acción is asking the Court to decide whether this expansion received adequate scrutiny under that process.
The lawsuit tests Aragón's planning model
Ecologistas en Acción announced its legal challenge on 21 January 2026, before the case was recorded as filed at the Aragón court in April. The action targets Amazon Web Services' planned 30-building expansion and argues that water, electricity and environmental effects received inadequate scrutiny.
The claim challenges the Programme of General Interest used for a development spanning land acquisition and construction. It asks the Court to test whether the approval process examined the project's water demand, electricity infrastructure and environmental effects closely enough. Aragón's court and public authorities control the outcome; Ecologistas en Acción is the claimant pressing for review.
