In recent years, as global environmental concerns have escalated, this responsibility has become increasingly crucial. To fulfil this mandate, education policies must transcend national boundaries.

To delve deeper into this significance, the author examines the emergence of ESD (Education for Sustainable Development), its accomplishments, and the challenges the world is currently grappling with.
