The purpose of this paper is to examine consumer education for a sustainable society, using the Theory of Socio-organic Systems. Firstly, this paper clarifies three conditions to realize a sustainable society, and it points out the limitation of the present theory of Home Economics, where life has been the subject of study. Secondly, it focuses on the role of “information” in a sustainable society, and points out that information is closely related to the development and formation of the inner-world of human beings. The inner-world embodies one's “lifestyle”. So it can be said that information determines one's “lifestyle”. Thirdly, the relationship between information and the conditions in a sustainable society is examined by looking at several recent social systems, such as political organizations represented by supranationalism, innovative enterprises and N PO, where information plays an important role. Finally, this paper proposes a path for consumer education aimed at a sustainable society. Here, information is seen as a key in establishing an environment for education, and developing consumers' independence.
