Abstract: In the case of the manufacturer with the characteristic of fairness concern, the pricing and emission reduction strategies of decision makers in single and dual channels are compared and studied by constructing two-member supply chain models. And the influence of the manufacturer's fairness concern and the coefficient of the product carbon on supply chain benefits are explored through mathematical deduction. The results are as follows. The retailer does not necessarily obtain more profits by opening dual channels. There exist different trends of the optimal pricing and emission under the level of fairness concern and the coefficient of product carbon. In addition, when the manufacturer considers the fairness of profit distribution, it will have a certain negative impact on all members of the supply chain and the overall profit. However, the manufacturer increases the proportion of its profits in the whole supply chain, thereby achieving its goal of pursuing fair distribution of profits.

Key words: equity concerns, dual channel, low carbon supply chain, product carbon coefficient
