This special section investigates the meaning and possibilities of justice at the global level. It does so by offering a first systematization of the current debate on this topic. ‘Global justice’ is a complex and multidimensional notion and, for this reason, we identify three thematic clusters, where the normative dimension of justice is confronted with the economic, socio-cultural and ecological components of our globalized reality. This exercise calls for the inclusion of all those different voices and disciplines involved in the contemporary debate.
