In recent years, the notion of global justice has marked the work of cooperation, peace, and human rights organizations in Catalonia, which has led to the conceptualization of a proposal to promote 'Education for Global Justice' (EpJG) in alliance with educational institutions and social movements. However, the theoretical foundations of EpJG are under construction and weakly articulated with practice. Therefore, this paper develops a conceptual framework of education and global justice and presents a documentary analysis of the main reflective material arising from the practices and experiences of the entities. In this context, a proposal for emancipatory education is observed that aims to provide insight into global ecology and interdependence, analyze the factors and causes responsible for inequalities in the world, and support critical educational innovation and the balance of knowledge. However, the proposal has certain limitations and requires addressing emerging issues to continue moving forward in these processes of change.
