Abstract: To study a four-echelon supply chain with fuzzy costs in the centralized decision mode how to make effective decisions for achieving the objective of minimization total costs under the carbon emission taxation scheme,a fuzzy programming model was developed,and was solved  based on fuzzy possibility theory.An example was given to demonstrate the feasibility and effectiveness of the proposed approach.The analysis of a given example showed that a reasonable carbon tax could let this supply chain enterprise change the decision to reduce the carbon emission,so as to achieve the dual goals of economic benefits and social responsibility.
