Acknowledging the inherent complexity of many sustainability challenges, and the shortcomings of traditional linear approaches in tackling them, we have seen a rise in design-driven approaches, which are deemed better suited in handling socio-cultural, economic and environmental implications. Existing literature shows that products and services guided by EcoDesign concepts have the potential to promote users’ behaviour towards a sustainable direction. However, due to the primary focus on the material aspect of design (e.g. environmental impact, reusability and recyclability), there is a lack of guidance for incorporating the behaviour perspective of users into the design research phase. This research aims to develop a framework to help designers determine factors that can possibly impact the behaviour of the target user. The study draws on theoretical insights obtained from a non-exhaustive literature review (observed to be driven by Global North perspectives) and a meta-synthesis of five case studies, primarily situated in the Global South. The findings showed that to influence users’ behaviour through design interventions, the designer would need to account for various determinants. We summarized these determinants into three lenses—context, culture and intent and then developed a conceptual framework based on these lenses. We believe this framework can guide designers in selecting relevant user behavioural determinants in their design research phase, thus supporting them in identifying what factors should be considered for introducing design interventions to promote sustainable behaviour.
