Background

The Programme of General Interest (Proyecto de Interés General) is a Spanish planning mechanism that allows regional governments to designate large infrastructure projects as being of general public interest, which can accelerate the planning and environmental review process. The instrument is designed for national-scale infrastructure — historically applied to motorways, energy networks, and large industrial sites — but has been applied to Amazon Web Services' 30-building data centre campus in the Aragón region.

Ecologistas en Acción's April 2026 lawsuit at TSJ Aragón specifically challenges the use of the Programme of General Interest for the Amazon campus, arguing it bypassed the standard environmental impact assessment that would normally apply to a project of this scale. The legal challenge targets both the water consumption and electricity demand implications of the campus, as well as the procedural propriety of the planning instrument used.

The Aragón regional government and AWS applied the instrument with the argument that the campus represents a major economic investment in the region. Opponents argue the public-interest designation for a private commercial installation stretches the legal intent of the instrument.
