Barcelona Airport Expansion Plans Under Scrutiny Amid Concerns for Natura 2000 Site Integrity

Strategic Insights -

Plans to develop Barcelona's Airport are facing criticism from environmental groups and concerned authorities, citing the potential impact on the Natura 2000 site Delta del Llobregat. The European Union's Habitats Directive requires a thorough assessment of any project's implications for Natura 2000 sites, which protect natural habitats and wildlife. The Spanish authorities have been asked to conduct this assessment before allowing the airport expansion to proceed. However, an ongoing infringement case regarding the inadequate protection of the Natura 2000 site has delayed the implementation of necessary measures, leaving the baseline for the assessment unclear.

Key Takeaways:

  • The European Commission has met with Spanish authorities and Aena (Spanish Airport Operator) to discuss the airport expansion plans, which aim to further develop Barcelona's Airport.
  • Pursuant to the Habitats Directive, any plan or project that may have a significant effect on a Natura 2000 site must undergo an assessment of its implications for the site.
  • The assessment has not been conducted yet, and the competent national authorities cannot agree to the plan or project until its results are known.
  • In the event of a negative assessment, compensatory measures must be taken to ensure the overall coherence of Natura 2000 is protected.
  • An ongoing infringement case regarding the inadequate protection of the Natura 2000 site Delta del Llobregat has delayed the implementation of necessary measures.
  • The Commission's Transparency Register lists the meeting between the Commission and the Spanish authorities, which took place on April 2, 2025.
  • The Habitats Directive requires the protection of natural habitats and wildlife, and any project that may affect these areas must undergo a thorough assessment.
  • The Regional Government of Catalonia is also involved in the discussions, as they have a responsibility to protect the Natura 2000 site Delta del Llobregat.
