As there is not enough demand against increasing supply, it becomes inevitable to be competition in market. Besides end users' awareness and sensibility is much more than before. Thus, manufacturers should control their all process from cradle to grave. Especially in last decade, consumers prefer more "green product" due to increasing environmental awareness. Manufacturers, who wants to respond that preference, should make their all supply chain green. The first step of this process is purchasing and supplier selection. This paper examines green purchasing and green supplier selection subjects, which are attracted attention by both academic researchers and manufacturers.
