Engineers are among those who are increasingly aware of the necessity to transform our society from being consumer-oriented to being preserver-oriented. To support the transformation, scholars and educators worldwide highlight the importance of sustainability and sustainable education within higher education. This research draws on ecocomposition pedagogy as a component of sustainable education. Ecocomposition integrates ecological literacy, language issues and writing skills development that allows integrating it into English for Specific Purposes course. Focusing on the integration and implementation of an ecocomposition course into ESP classes for engineers in Ukraine, this paper highlights the importance and significance of the course that is both experiential and that introduces diverse perspectives. We created the short course on ecocomposition and conducted quantitative and qualitative studies to verify the efficiency of ecocomposition for foreign language learning. Key pedagogical strategies, practical suggestions, and students' responses are discussed in the article. The results revealed that ecocomposition might serve as a productive tool to analyze text discourse, to enrich students' vocabulary with field-related terminology, to familiarize with composition types and registers, to enhance writing skills and to provide a personal developmental move toward sustainable lifestyle. However, some barriers exist among teachers and students because this approach is complicated, innovative, and requires certain training and comprehension. The paper provides guidance on designing and integrating an ecocomposition course into ESP course for engineers.
