This article responds to recent calls for more creative expressions of climate and sustainability transformations. In particular, research literature argues that the formulation of new narratives of sustainable societies may function as a prominent intervention for system changes. Yet, few empirical studies exist on how creative climate and sustainability storytelling elicit varying levels of awareness and engagement. With the intention to advance scholarship in the role of narratives to create engagement with sustainability transformations, this study investigates children’s theater for the UN Sustainable Development Goals (SDGs) as one research site. By analyzing the interactive children’s theater play “Esmeralda and the Dragon—The Global Sustainability Goals,” we show that creative storytelling can offer a meaningful space for engagement with Agenda 2030 and the UN SDGs. In particular, we find that (1) children’s cognitive and emotional associations and experiences shape the meaning of and responses to the SDGs and (2) the play’s fictional elements resonate with children’s emotional frameworks. Based on the results, we argue that new stories are needed for sustainability transformations and that there is transformative power in the creative and performance arts in this respect, and we call for further exploration of various publics engagements with sustainability storytelling.
