Resumen: This study examines the different levels of adoption of sustainability practices among Spanish universities and the factors that drive them to disclose stand-alone sustainability reports. The findings reveal three patterns of adoption of sustainability practices and indicate that only around one third of Spanish universities disclose up-to-date sustainability reports on their websites. Disclosure is positively related to universities’ commitment to sustainability and their participation in international sustainability rankings, reflecting a strategic orientation of the organization towards sustainability. This article’s main contribution to previous literature is the analysis of sustainability practices and sustainability reporting in a whole university system.
