This book analyzes the concept of sustainability as it applies to internationalization of higher education. The topic of sustainability is relatively well explored in the context of higher education. It is becoming increasingly discussed by scholarly societies in international and comparative education. However, there is still a dearth of studies on the topic within the narrow field of international and comparative education. This book presents an organizing framework to explore sustainable internationalization in a comprehensive way and offers practical insights on how sustainable internationalization can be achieved in various aspects of internationalization.
