Jewish holidays and rituals contain untapped ecological wisdom that can help synagogues become environmental leaders in their communities. Through a comprehensive framework developed by Shomrei Adamah ("Keepers of the Earth"), congregations can integrate environmental stewardship into four key areas: ritual life, education, physical plant management, and special programs. The methodology combines systematic analysis of traditional Jewish sources with practical applications, revealing how ancient environmental principles within Judaism remain relevant for modern sustainability challenges. Analysis shows how the Sabbath serves as a model for sustainable living, while agricultural elements of festivals like Passover and Tu Bi-Shevat offer opportunities for ecological education. Prayer practices themselves can cultivate environmental awareness when properly framed. The framework provides detailed recommendations for educational programming, energy conservation, waste reduction, recycling initiatives, and environmentally safe product use in synagogue operations. By implementing these strategies, synagogues can serve as moral trend-setters modeling ecologically sound behavior. This research advances religious environmentalism by demonstrating how traditional Jewish practices can address contemporary ecological crises while preserving spiritual authenticity and cultural continuity.
