This technical note outlines why community insights and trust are fundamental to effective social protection systems for climate resilience, and how they can be systematically integrated into programme design and implementation. It is intended for National Red Cross and Red Crescent Societies, humanitarian practitioners, and partners working at the intersection of social protection, climate action, and community engagement and accountability. The document introduces the Community Trust Index as a practical tool to measure and strengthen community trust in social protection interventions and proposes the development of a specific Module for Social Protection. By illustrating how trust data can inform targeting, accountability, and community engagement, the document aims to support more inclusive, adaptive, and people-centred social protection systems that are responsive to climate risks and grounded in local realities.
