The role of 3R (Reduce, Reuse, and Recycle) in constructing the Eco-society or Eco-city has been comprehensively recognized and promoted worldwide over the past two decades. Nowadays, several hot issues such as the energy saving, CO 2 reduction, and eco-society have received great attention. Approximately 40% of global energy is used in the construction and subsequent operation stage, while a large amount of construction waste is produced during construction and after demolition. In Taiwan, the government continuously makes great efforts to promote the development of green building materials produced with the recycling construction waste over the past decades. However, the recycling green building materials are not extensively accepted and used in the construction industry of Taiwan. The objective of this study is to propose a strategy for promoting the recycling green building materials through the investigation of "cradle-to-cradle" life cycle of construction products. The key factors lowering people's impression and purchase behavior have been studied. The disadvantage of existing policy of government is also discussed and compared. Finally, the present study attempts to propose a feasible strategy to assist government to promote the utility of recycling green building materials.
