The R&D paradigm for the Materials Technologies involving Environmental Consciousness(MTEC) is sought in this paper with an emphasis on the background and importance of the METC. In this paper the MTEC is defined as "Green Materials Technology", and the Green Materials Technology is classified into four categories based on life cycle of the materials; circled1Ecomaterials technology(materials design), circled2Envimatec technology (manufacturing process), circled3Materials life technology (use & maintenance) and circled4Materials recycling technology (waste disposal). Each these four categories was introduced. In conclusion, the main R&D field and strategies for the four categories of the Green Materials Technology were suggested.
