Many scholars have emphasized the importance of sustainability management in small and medium-sized enterprises (SMEs). Although various publications discuss different approaches and potential barriers of implementation, a review of the existing research on sustainability management tools for SMEs is nonetheless missing. Based on a systematic review of the academic literature, this paper discusses reasons why SMEs should implement sustainability management tools. A further analysis reveals that most such tools are perceived to have little to no implementation in SMEs. The main implementation barriers and facilitating criteria are discussed. In addition, implications for future research, SME management, and public policy are drawn.
