As exchanges and cooperations among Korea, Japan and China about environmental issues become active, exchange programs about social environmental education increases. Therefore, in this study, the present state of the social environmental educations in Korea, Japan and China is analyzed and compared. The conclusions are as following. First, the social environmental education in Korea is mainly executed by NGOs about environment, religion and gender. In the social environmental education in Korea, education for sensibility in which all the people can participate such as field investigation, camping and travel holds the majority. However, the education about social-political knowledge which deals with environmental policy and economy is not sufficient. Second, in the social environmental education in Japan, the education of environmental education methods and knowledge about environmental issues, in which citizens participate such as workshop and forum holds the majority. Third, the social environmental education in China is mainly executed by CEEC under SEPA. Education toward teenagers for fostering environment-friendly attitude is mostly active, and lectures are in general. However, education for the specific knowledge of environmental issues is not enough. The social environmental education is very significant as lifelong education for environment friendly welfare society since civil decision-making leads directly the social behavior. Therefore, efforts must be made to develop the social environmental education of each countries by means of active exchange and energetic support of the social environmental education program and autonomous exchange of NGOs for the social environmental education.
