 The aim of the current study was to systematically develop a comprehensive definition of sustainability, based on definitions already used in the literature. We identified four knowledge synthesis of sustainability, which identified 209 original articles. These definitions were mapped to three constructs from an existing definition, and nine new constructs emerged. The comprehensive definition was revised to include emerging constructs. This article was authored by Julia E. Moore, Alecia Moscorranias, Julie Bain, and others.
