We communicate, relate, educate and make our world meaningful through stories. Stories are integrated in and are a part of every sustainability issue. In this article, we develop the concept of sustainability stories, and how they can be assessed and developed to correspond with the intentions of education for sustainable development (ESD). Literature shows that valued competences such as action competence, systems perspectives, student engagement and critical reflection have difficulties when it comes to informing educational practices in profound ways. In this article, we argue for the use of sustainability stories as an educational strategy to overcome this problem. Here the didactical tool ecolocigal, pluralism, organisations, social, economic and, agents (EPOSEA) aids teachers in enhancing their ESD classroom activities as well as providing a tool for co-producing sustainability stories. We argue for the potential of serious stories in ESD to holistically engage learners in exploring complex issues.
