Conference programme, promotional poster, and exhibition materials for the scientific outreach symposium “Crisi socioambiental global i canvis en els estils de vida”, held at the Faculty of Geography and History of the Universitat de Barcelona (UB). This symposium aimed to disseminate and transfer key topics from the environmental microcredential organised by the University of Alicante (UA) to the UB, including an exhibition of outreach posters adapted into Catalan. The scientific programme was structured into two main thematic sessions: 1. Climate crisis and biodiversity loss: Core planetary boundaries, focusing on the analysis of global change impacts. 2. Perception, communication, and lifestyle changes, addressing environmental awareness, communication strategies, and sustainable behaviours. The event received financial and institutional support from the Faculty of Geography and History (UB).
