The language of "Green Islam" has gained global visibility through initiatives such as Green Mosques, Green Ramadan, and Green Ḥajj. While effective as symbolic mobilization, such initiatives often lack the legal and institutional mechanisms required to address systemic climate vulnerability and environmental inequality. This paper examines this implementation gap through a case study of Jordan's religious infrastructure, focusing on the relationship between faculties of Sharīʿah and the Ministry of Awqaf. Drawing on desk research, twelve semi-structured interviews with academics, imams, and senior practitioners, an online survey of Sharīʿah students as the future workforce of the Ministry of Awqaf, and a multi-stakeholder workshop involving deans from major Jordanian universities, the study analyses how environmental knowledge circulates—or fails to circulate—between higher education and religious governance. The findings reveal a pronounced structural silo: while universities increasingly generate ethical discourse and innovative courses on environmental issues, these insights are not institutionally translated into the Ministry's field practices. Survey data indicate strong ethical motivation among students but a lack of juristic tools to address concrete issues such as water scarcity, pollution, or illegal logging. In response, the paper proposes a normative legal framework inspired by al-Ghazālī's hierarchy of values, reclassifying environmental preservation as a religious necessity rather than a voluntary virtue. Building on contemporary scholarly discussions that frame pollution as fasād fī al-arḍ, the study outlines a practical roadmap for climate resilience in Jordan, including targeted micro-credentials for preachers and the revival of ecological waqf as community-based climate resilience hubs. By linking jurisprudence, pedagogy, and institutional reform, the paper demonstrates how Islamic law can move from symbolic ethics to actionable climate governance.
