This study examines the trends and current state of Environmental, Social, and Governance (ESG) courses offered by Taiwanese universities between the 2021 and 2023 academic years. Using content analysis, this study analyzed course syllabi, focusing on the topics covered, the sustainability competencies aimed for development, and the teaching and assessment methods employed. A total of 152 course syllabi were included for analysis. The findings reveal that over the three academic years, universities in Taiwan offered 138 ESG-related courses across 185 offerings. Nearly 70% of these courses were provided by departments in business, management, and law, whereas no units within the education sector offered such courses. Regarding course content, the primary focus was on the governance dimension, followed by the environmental and social dimensions. The core competencies most commonly targeted for student development included systems thinking, interpersonal communication and collaboration, professional knowledge, justice, responsibility and ethics, and global and international perspectives. The most frequently utilized teaching methods were lectures, group discussions, case studies, and guest speeches, while common assessment methods included reports and performance observations. Finally, this study recommends that universities regularly update their ESG course content, adopt more active learning methods, and employ diversified assessment strategies to enhance student competitiveness. By illustrating the current implementation of ESG courses in Taiwanese higher education, this study provides a valuable reference for future research in sustainability education.
