As universities take actions to support the achievement of the Sustainable Development Goals (SDGs), Yamaguchi University has focused in part on visibility, making information about which SDGs are taught in each class easily accessible on the online syllabi. This can be valuable data to students, but it is also important for the university to have a better understanding of how well these SDGs are integrated into classes and where there is room for improvement. This study investigated the extent that SDGs have been implemented into course syllabi in general education classes. SDG frequencies were investigated for both faculty and class type, and were found to be more frequent in English language courses, and of similar overall frequencies but varying compositions between faculties.
