This research explores the concept of green social work in Croatia. The aim of the research was to examine the extent to which social workers are familiar with the concept of green social work, identify specific examples of its application, and determine the barriers and potential benefits of this approach. The study was conducted with a sample of 169 social workers in Croatia through web surveys. Four key categories were examined: ecological sensitivity, awareness of climate issues in the context of marginalized groups, familiarity with the concept of green social work, and the integration of this approach into daily practice. The results show that most social workers recognize the value of incorporating ecological aspects into social work. Although there are sporadic examples of its application, the concrete integration of green social work is still not widespread. Differences in the perception and application of green social work were found across various sectors and based on sociodemographic data. The major barriers identified include a lack of institutional support, resources, and education. The research describes the significant positive impact that green social work can have on marginalized groups and the community as a whole. It also suggests the need for further education of social workers on ecological issues, the development of policies to support broader implementation of green social work, and emphasizes the importance of improving institutional support, developing infrastructure for implementing ecological practices, and strengthening intersectoral collaboration.
