This report, Intercultural Dialogue and Engagement for Sustainable Climate Action, explores how intercultural and interreligious dialogue can foster more inclusive, ethical, and effective responses to the global climate crisis. Through a narrative-analysis methodology, it examines three diverse case studies: Pope Francis' faith-based environmental leadership, the Shinnecock Indian Nation’s advocacy for ecological justice and Indigenous sovereignty, and the Pacific Climate Warriors’ youth-led resistance through storytelling and performance. The study argues that intercultural dialogue offers a transformative pathway to bridge global climate policies with lived cultural and spiritual perspectives, while also acknowledging challenges such as power imbalances, tokenism, and the limitations of current dialogue frameworks. It concludes with policy recommendations for integrating underrepresented voices into climate governance.
