The pursuit of a sustainable society has received more and more attention during the last decades, due to global problems of population growth, climate change, financial crises, and others the world has been confronted with. Over the years, universities have tried to take up their role within the process of achieving sustainable development, by sharing thoughts and ideas via conferences, the development and signing of declarations, and through individual actions in the field (e.g., development of SD courses, teacher trainings on SD, or “campus greening” initiatives). Despite the diverse array of sustainability integration initiatives undertaken by higher education institutions, it is very difficult for both their internal and external stakeholders to objectively assess the extent to which a university has implemented sustainability integration initiatives within the four major core functions of a university—i.e., education, research, operations and community outreach. The definition of appropriate accounting instruments that monitor, analyze and control the performance of sustainability initiatives and of the institution as a whole could contribute to resolving some of these problems for university stakeholders. Universities have tried to voluntarily report on their efforts of SD integration via sustainability reporting, following the upsurge of this type of reporting in the corporate world. Nevertheless, sustainability reporting in higher education is currently still in its early stages. This seminar will present some of the findings of the PhD research started up in 2011 on the topic of sustainability reporting in higher education, based on both literature review and case study research at HUB, the first Belgian higher education institution with a GRI sustainability report.
