Sustainable development is a major concern all over the world. Indeed, it is required in every domain of life, including that of government. E-services are widely acknowledged for the contribution they make to e-government. The research question raised in this study is: What is the existing status of e-service sustainability research? The research method used is a literature study that adopts a concept-centric approach. Literature was collected from high-ranking IS journals and relevant databases. Selected literature was then analyzed using the twin concepts of e-service sustainability itself and the enabler (secondary) effects of sustainable e-services. The Triple Bottom Line’s model was used to further categorize the findings using economic, environmental, and social sustainability concepts. Finally, the selected papers were analyzed in terms of research approach and topic. The results of the study revealed a lack of research into e-service sustainability. By way of contrast, it revealed 20 articles that cover the enabler effect. Existing research is related to economic and social dimensions, with the most common topic being related to user satisfaction.
