The Roundtable on Sustainable Palm Oil (RSPO) brings private sector and civil society groups under a system of governance to ensure the sustainable, equitable, and humane production of palm oil. The RSPO includes a grievance mechanism that seeks to remedy the reported violations of its members. This paper builds upon a large body of scholarship examining the effectiveness of the RSPO’s conflict resolution through an in-depth investigation of the published correspondences of a complaint case involving PT. PP London Sumatra Indonesia Tbk (a subsidiary of Indofood Agri Resources Ltd) and three non-governmental organizations (NGOs). Using methods of textual analysis through NVivo and temporal analysis, this research identifies and distinguishes narratives of collaboration, opposition, and compliance used by the RSPO, NGOs, and palm oil suppliers to influence outcomes in a grievance process. The interaction of these narratives highlights strengths and gaps in the RSPO’s ability to produce trust and mediate conflict.
