For the increasingly serious global environmental pollution and rising awareness of environmental protection, a method for green design based on the environmental requirements is put forward. This paper lists the basic content based on the environmental requirements. On the grounds of knowledge reuse, the existing products’ conformity degree model is built on base of the fuzzy set theory. The fuzzy-analytic hierarchy process (F-AHP) and fuzzy set theory are used to determine the importance of the product's environmental requirements. In this paper we calculate the determination of the existing product with the each environmental requirement and the comprehensive conformity of the product. Then we can choose the best products to modify the design and achieve the purpose of green design. Finally we give the final green design method based on environmental requirements. In the product on the analysis of the conformity degree of the various environmental requirements, the method combines with the fuzzy analytic hierarchy process and fuzzy set method to effectively choose the best product that highly meets environment requirements to optimize and shorten the design cycle. Taking the design of the CNC machine tool as an example, we can get the validation that the method is an effective method of product green design.
