Abstract
Using the concept of consumer citizenship and with a view to sustainability, we examined how consumer education can respond to new problems arising in the sharing economy that transcend the traditional framework. In order to examine the possibility of consumer education regarding problems of interpersonal transactions (C to C) and the issues created by the duality of the sharing economy, we extracted three ideas related to the sharing economy from literature on the formation of consumer citizens. As a result, we were able to clarify the relationship between the sustainability of the sharing economy and the theoretical framework of consumer education, and reveal new possibilities for consumer education.
