<![CDATA[Purpose – This study examines how Islamic da'wah institutions contribute to pro-environmental behavior grounded in Islamic values, through which mechanisms those values are internalized, which strategies institutions employ, and where the evidence remains weak. Design/methodology/approach – A systematic literature review guided by PRISMA 2020 searched Google Scholar, Garuda, SINTA and DOAJ, supplemented by citation chasing and Scopus-indexed publisher platforms. Thirty studies published between 2016 and 2026 were synthesized thematically and classified into three evidence tiers: empirical, review-based and conceptual. Findings – Four themes emerged. The values of khalifah, amanah, mizan and the prohibition of fasad form the normative base. Institutions act as educators, communicators, role models, empowerers and mobilizers. Five strategies recur: message integration, eco-mosque modeling, community participation, digital da'wah and measurable programs. Internalization follows a norm activation pathway from awareness of consequences and ascription of responsibility to personal and social norms, conditional on institutional opportunity structures. Nineteen studies are empirical, nine are reviews and two are conceptual; the surveys rely on intentions and self-reports, and, on the authors' reading, none followed congregants' behavior over time. Research limitations/implications – The corpus is limited to Indonesian and English publications and to heterogeneous designs; the integrative model is an evidence-graded framework whose five propositions require longitudinal and experimental testing. Practical implications – Mosque managers, religious organizations and policymakers should pair value-based preaching with facilities and measurable indicators of waste, plastic, energy and water behavior. Originality/value – The study shifts the analysis of religion and environmental behavior from individual religiosity to institutional mediation, offers a transparent corpus and separates empirical findings from cross-study synthesis and conceptual inference.]]>
