The carbon emission reduction coordination of fresh supply chain based on the limited carbon quota and trading

In this paper, against the background of low-carbon fresh supply chain, the government of carbon quota for the whole supply chain is limited and the carbon training policy is exist, we analyzed the centralized and distributed decision-making scenario how the producer and retailer cooperate on the carbon emission reduction, then studied the interaction between the emission reduction rate of producer and retailer, and comprise the average emission reduction rate of supply chain, also explore the impact of carbon trading price on emission reduction in four situations. The results shows that at what conditions of the carbon emissions reduction make sense, also get the conclusion that in centralized decision-making scenario, the emission reduction rate of supply chain is optimal, and with the higher training price, the emission reduction rate is higher too, vice versa. The conclusions provide some intellectual support for enterprises to make rational emission reduction strategies. This paper theoretically support the methods of cooperation for supply chain.
