This paper contributes to the discourse on education for sustainability and global citizenship, and Soka studies in education through a study of the Instituto Soka Amazônia (Soka Amazon Institute), a non-governmental organization located in Manaus, Brazil. It examines the educational activities within the Institute as a non-formal space of learning for global citizenship and engages with its manifold contributions to sustainability: to preserve biodiversity in the Amazon region; as a Sustainable Development Goals hub; the relevance of the founder’s vision for the harmonious coexistence of all life; and the use of the Earth Charter as an ethical framework. This paper draws relevance for Soka studies in education in non-formal learning spaces, as well as the broader implications for education for sustainability and global citizenship.
