Environmental crises and the growing demand for sustainable development have encouraged educational institutions to transform their governance toward more sustainable practices. However, previous studies on Green School Management have largely focused on environmental programs, eco-friendly facilities, or curriculum implementation, while paying limited attention to institutional governance and the integration of Islamic values. This study aims to develop a conceptual model of Green School Management Based on Islamic Values (GSM-NI) as a governance framework for promoting Sustainable Education in madrasahs. This research employed a qualitative library research approach through a systematic review and conceptual synthesis of literature on Green School Management, Education for Sustainable Development (ESD), educational management, and Islamic environmental ethics. The findings indicate that sustainable madrasah governance should be built upon the integration of seven interrelated components, namely Green Leadership, Green Governance, Green Curriculum, Green Culture, Green Facilities, Green Partnership, and Green Evaluation, which are philosophically grounded in the Islamic values of tauhid, khalifah, amanah, mizan, ihsan, islah, and hifz al-bi'ah. The proposed GSM-NI model demonstrates that sustainable education is achieved not merely through environmental programs but through an integrated governance system that transforms leadership, organizational culture, curriculum, institutional policies, and stakeholder collaboration. The novelty of this study lies in synthesizing Green School Management, Education for Sustainable Development, Educational Management, and Islamic values into a comprehensive conceptual framework for sustainable madrasah governance. The model contributes theoretically to the advancement of Islamic Educational Management and provides practical guidance for policymakers and madrasah leaders in designing environmentally responsible and value-based educational institutions.
