For any transition towards sustainability to be successful, it is necessary to understand the knowledge, attitudes and practices (KAP) -- related to sustainability -- in different populations. A systematic review was conducted to identify and analyse KAP studies on sustainability that were reported in the scientific literature during the period of 1990-2016. Ten studies were found, of which half were conducted among populations in educational environments, i.e., teachers, students and graduates. The KAP results vary among the studies; however, there is a general tendency to investigate aspects related to ecosystems, natural resources, environmental protection and conservation. The present study concludes that it is necessary to conduct KAP studies that include categories that reflect on the wide range of meanings of sustainability and the attitudes and practices that would arise from such perspectives. This finding also reveals dimensions of sustainability usually omitted by KAP studies of sustainability.
