The terminology employed to explore consumption ethics, the counterpart to business ethics, is increasingly varied not least because consumption has become a central discourse and area of investigation across disciplines (e.g. Graeber, 2011). Rather than assuming interchangeability, we argue that these differences signify divergent understandings and contextual nuances and should, therefore, inform future writing and understanding in this area. Accordingly, this article advances consumer ethics scholarship through a systematic review of the current literature that identifies key areas of convergence and contradiction. We then present the articles in this Journal of Business Ethics Symposium and analyse how these articles fit within the interdisciplinary themes. Subsequently, we develop a transdisciplinary theoretical framework that encapsulates the complexity and contextual nature of consumption ethics. We conclude by outlining how genuinely transdisciplinary research into the intersection of ethics with consumption may develop.
