In the face of escalating environmental challenges such as climate change, biodiversity loss, deforestation, and resource depletion, education has emerged as a crucial tool for fostering sustainability. Global education policies play a pivotal role in shaping environmental awareness, instilling sustainable practices, and influencing both individual behaviors and large-scale policy frameworks. This study explores the intersection between education policies and environmental sustainability, assessing how national and international educational frameworks contribute to sustainable development. The research examines how international organizations, governments, and educational institutions incorporate sustainability principles into curricula, teacher training, and policy structures. Key international policies such as the United Nations Sustainable Development Goal (SDG) 4.7, UNESCO’s Education for Sustainable Development (ESD), the Paris Agreement’s climate education provisions, and OECD’s guidelines on green skills provide foundational strategies for integrating sustainability into education. Additionally, national policies from developed and developing countries are analyzed to assess their effectiveness in promoting environmental responsibility among students and the general public.
