The increasingly unavoidable need for sustainability in the music sector calls for theory and practice to join forces towards a real paradigm shift. In this panel, we find the expertise of Carlos Ribeiro – Executive President of the Laboratório da Paisagem (Landscape Laboratory), responsible for the European Green Capital 2026 – who presents an event manual with recommendations for best practices, and also Rob van Wegen, coordinator of the Eurosonic sustainability plan, who will talk from the perspective of the applicability of standards that produce a concrete effect, in what is the most important European Festival Showcase & Conference.
