With nudges, conversational agents (CAs) can be used to recommend environmentally sustainable products to individuals shopping online. CAs can thus influence individual purchase behaviors and have the potential to promote green decision-making. There is a lack of qualitative insights into how CA nudges might influence the purchase decisions of individuals in the specific context of sustainable fashion consumption – especially regarding customer perceptions of CAs trying to influence those decisions. We conducted an explorative survey with a qualitative online questionnaire of 79 fashion shoppers to determine how they think about CAs nudging their product choices and to derive propositions on how CA nudges should be designed to support green decision-making.
