During the last few years, there has been a growing concern for environmental justice within international social work. This article connects to such concerns and aims to present and discuss environmental injustices faced by local communities in Mauritius, Peru and Sweden. Primary data were collected through face-to-face semi-structured interviews with a total of 25 key representatives of local communities in the three countries. Secondary materials were combined with the primary data in ATLAS-ti v.8.3 for a deductive critical discourse analysis. The findings describe the substantive, distributive and procedural environmental injustices faced by local communities in the three case studies. The article then considers the implications of the findings for international social work interventions in promoting environmental justice. The article concludes on the need for international social workers to continue their efforts and practices towards achieving environmental justice for all, in promoting global sustainable development.
