Sustainability Rankings of Universities

University rankings have almost 40 years of history. The introduction of the sustainable development concept in 1989 has increased sustainability awareness among higher education institutions worldwide. This awareness of the environmental, social and economic impacts that higher education institutions use via their daily operations as well as long-term by educating future engineers, decision-makers, entrepreneurs and future leaders leads to the reporting about their statuses and, finally, comparisons. The first sustainability ranking was launched in 2007 at the national level and in 2010 at a global one. This chapter introduces a comprehensive examination of sustainability rankings, from their emergence to the present day, encompassing both critiques and commendations associated with these rankings. It tracks the sustainability rankings research from the content perspective, addresses prevailing challenges and explores potential future directions in this domain, focusing on methodologies, indicators and data.
