Abstract

Climate change is not only a technical and environmental challenge but also an emotional and psychological one that affects public engagement, policy acceptance, and long-term sustainability. This study presents a conceptual framework based on the Kübler-Ross model from psychotherapy to explore emotional responses to climate change: denial, anger, bargaining, depression, and acceptance. Based on a thematic analysis of the interdisciplinary secondary literature and illustrative cases, we analyse how these emotional dynamics influence climate mitigation and adaptation efforts. Each stage reveals specific psychological barriers and entry points for communication, resilience-building, and policy design. We argue that emotional readiness is a critical yet underacknowledged factor in sustainable development and societal transformation. Addressing emotional dimensions can support mental health, increase acceptance of climate measures, and improve the alignment between sustainability strategies and public responses. Our findings emphasise the importance of tailoring sustainability communication and policies to different emotional stages to foster inclusive, effective, and lasting climate action.
