This paper is to examine the change in the concept and terminology of ‘green growth’ and ‘green tourism`` in Korea. The meaning of green tourism is being changed under current Korean government and the most difficult problem of the new concept of green tourism is that green tourism and green growth are being considered even more broader concepts than those of the sustainable development and sustainable tourism. This is problematic because the goal of green growth is foremost economic development, while the goals of sustainable development include economic and social progress, protection of the environment and use of natural resources. In this regard, this paper proposes that the concept and meaning of the sustainable development and sustainable tourism is superior and broader than green growth and green tourism. It also stands on that the developing of new concept and terminology should be formed from the structure of synchronie and diachronic.
