Former Transport Minister Clément Beaune agreed last May to launch studies on capping Ile-de-France airports. Around a hundred people, including around thirty elected officials, mobilized in front of the Val-d'Oise prefecture in Cergy.

The gathering was organized by the Association for Defense against Air Nuisances (Advocnar) and the collective No to T4 (Terminal 4) They ask once again for a reduction in traffic at Roissy airport, the impact of which they denounce on their health.
