Those oil firms….”have been aided and abetted by advertising and PR companies – Mad Men fuelling the madness…..I urge every country to ban advertising from fossil fuel companies.”
António Guterres, UN secretary general, June 2024
Following previous international gatherings in Paris (2022), Amsterdam (2023) and Brussels (2024)- activist groups, NGOs, academics and reaearchers gathered in Barcelona from 11th – 14th September 2025.

Paper Planes: actions against airline advertising
We were also delighted to learn about a local subvertising campaign against airline advertising, the expansion of Barcelona airport and over-tourism in the city. The group ‘Climate Agency’ converted the bus stop adverts in 50 ad spaces into paper aeroplanes with the words ‘CAIGUDA LLUIRE’ which means FREE FALL in catalan – citing the need to drastically reduce aviation emissions. The action was announced on 16th September 2025, the International Day for the Conservation of the Ozone Layer, to commemorate the commitment of the international community to solving that problem – and to contrast the lack of meaningful action on aviation emissions. The intervention was covered in the national Spanish newspaper El Diario.
The group are calling for Barcelona residents to repeat the action until the expansion plans for El Prat airport in Barcelona are dropped. The group published a tutorial to explain how to do the action.
