Environmental sustainability in educational institutions is a critical concern for addressing global challenges. This research presents a comprehensive framework for sustainable energy conservation, behavior change, and recycling practices in schools, with the aim of fostering environmental consciousness among students and enhancing overall educational quality. The framework integrates solar photovoltaic (PV) systems, encouraging students’ participation in their maintenance while repurposing collected water for plant irrigation and using organic waste as a natural fertilizer. By creating a micro-ecosystem within schools, the approach cultivates a generation of environmentally aware individuals who actively contribute to environmental stewardship. The framework aligns with Saudi Arabia’s 2030 vision of improving quality of life and increasing green surfaces. It promotes environmental awareness, facilitates clean energy adoption, and reduces operational costs. The role of municipalities and recycling bodies is crucial for its successful execution, involving waste management support, educational programs, and regulatory compliance. Through collaboration between schools, municipalities, and recycling bodies, the framework aims to create a culture of sustainability. It envisions students as advocates, gaining experiential knowledge in renewable energy technologies and waste management. This research offers a roadmap for schools to integrate solar energy, behavior change, and recycling practices, positioning them as leaders in environmental stewardship. The framework underscores the importance of collaborative efforts, financial support, and awareness campaigns. By embracing this comprehensive approach, schools can play a pivotal role in mitigating climate change, promoting sustainable living, and inspiring a brighter future for generations to come.
