This study engages with how sustainability stories can assign meaning to sustainability matter in different ways. The study contributes to discussions on how to combine facts, norms, and the democratic action competence in pluralistic approaches in Environmental and Sustainability Education. A special focus is put on how co-created sustainability stories can be used to provide, explore, and expand shared experiences of sustainability. The analysis engages with how content is defined and made relevant through stories, how they represent matter as pre-defined problems and solutions or as an invitation to exploration and reinterpretation, and how competences for sustainable development are made visible through the characters. The method used is a holistic narrative content analysis of 21 sustainability stories, co-created by pre-school teachers and their children. Three selected stories exemplify the results and show how some stories manage to move back and forth between on the one hand assembling sustainability matter as concrete problems to be solved, and on the other hand as open-ended issues promoting critical reflection. The main conclusion is that these, promising but yet uncommon, stories best represent pluralistic perspectives, creativity, and democratic action competence.
