Purpose: Environmental social work (ESW) is an approach and a perspective in social work focusing on ecological and environmental sustainability and justice within the context of sustainable development (SD). This study aims to analyse students' reflective tasks on challenges for ESW education and practice from a critical theory perspective. The purpose of this study is to discuss the implications of the findings for accelerating the implementation of SD in social work curricula.

Design/methodology/approach: The research participants comprised 49 master level students from four different cohorts studying the course "Social Work and Sustainable Development" at the University of Gavle, Sweden. The sample comprised only those students who had completed at least one of the three non-mandatory reflective tasks that were set within the course. The reflective tasks of the research participants were gathered as data for this study. A qualitative methodological approach with the help of ATLAS-ti V8.4 was used to analyse the gathered data.

Findings: This study discusses three primary results, which are categorised as "Being Boxed", "Safe and Saviour Sweden" and "Politics and Power". Based on the results, this study argues for a transformative and emancipatory pedagogy (TEP) in the teaching and learning of ESW to accelerate the implementation of holistic SD within the social work curriculum.

Originality/value: Within the context of SD, there is a global call for social work education to shift from an anthropocentric to an eco-centric paradigm. However, ESW education is still in its infancy stage and very few universities are focusing in this particular area. This study therefore brings an important and well-needed layer of empirical evidence in considering the implications for catalysing environmentalism within the social work curricula.
