Antecedents, Decisions & Outcomes of Sustainable Luxury Consumer Behaviour: A Systematic Literature Review & Future Research Agenda

The study presents a systematic literature review on sustainable luxury consumption behaviour (SLCB) in the light of SDG 12 and translates the findings of that literature into usable insights for researchers, marketers and policymakers. Using the antecedents, decisions and outcomes (ADO) framework, this study seeks to consolidate the area intersection between diametrically opposed ideas of luxury and sustainability. Based on extensive coverage of 57 studies published over a period of 17 years between 2005-2022, nascent literature on sustainable luxury consumption is reviewed. Three primary streams of research were identified: (1) how consumers purchase luxury items (2) how consumers use or consume luxury items (3) how consumers dispose luxury items, all three rooted in the generic attitudes of luxury consumers in their interactions with sustainability to lay out variables that pinpoint the aforementioned behavioural trends. The study also discusses influences of particular gender on SLCB. This study bears implications for managers, environmentalists, consumers and luxury enthusiasts. The research in area is nascent and many areas remain underexplored. By synthesising extant literature, the aim of this study was to identify gaps in knowledge and to prepare for a future research agenda guided by intersectionality.
