Purpose: This study aims to investigate the potential of an empathetic mindset aimed at empowering undergraduate students to work toward sustainable development (SD), addressing both theoretical and practical dimensions. Design/methodology/approach: A mixed quantitative and qualitative research method was used in this study. Cross-sectional quantitative survey data on students' mindsets and actions toward SD was collected to examine the theoretical relationship between belief and behavior. Qualitative inquiry using focus-group interviews explored students' on-site learning experiences. Findings: This study provides evidence for the impact of an empathetic mindset on education for sustainable development (ESD). Results showed that students with a more empathetic mindset showed better attitudes and behaviors toward SD actions. Findings suggest that developing an empathetic mindset improves students' attitudes toward taking substantial action to protect the environment. Originality/value: This study introduces a novel perspective extending the application of empathetic mindset in ESD.
