Sustainability education is a structured educational approach that equips learners with the knowledge, values, competencies, and agency needed to address environmental, social, and economic challenges in integrated ways [1][2][3][4][5]. It goes beyond teaching sustainability topics as isolated content by fostering systems thinking, critical reflection, futures thinking, and action competence for real-world problem solving [1][2]. Sustainability education is characterized by interdisciplinary learning, participatory pedagogy, context-based inquiry, and attention to justice, equity, and long-term responsibility across local and global scales [2][3][4][5]. In policy and research contexts, the term denotes intentional educational processes aligned with sustainable development goals and societal transformation, rather than general environmental awareness activities without explicit competency and action-oriented outcomes.
