摘要:As part of sustainable development, more attention is being placed on consumer behavior. Revised economic models have resulted in an understanding of the need for a circular economy. In this perspective, the consumer is not merely the buyer of the product but also a seller in consumer-to-consumer (C2C) activities, here referred to as re-commerce. In this qualitative study, researchers conducted in-depth interviews of 32 respondents from two countries who had second-hand product trading experience on Facebook. The study uses thematic content analysis to analyze the themes of ethical pro-environmental self-identity (PESI) practices in the respondents’ everyday lives. In this study, challenges relating to understanding conditions for fruitful re-commerce are framed in a social practice theory. Focus is placed on ethical pro-environmental self-identity in the context of selling or buying products in Bangladesh and Sweden. The contributions of this study relate to consumer perspectives on what enables re-commerce for six selected product categories. The study also points to the importance of social media and context-bound differences between product groups as well as individuals in two national contexts.
