Abstract: In the context of government’s carbon emissions cap and trade, this paper introduces the altruism behavior into the model of low-carbonization supply chain, and establishes completely selfish preference and altruistic preference newsboy models based on the wholesale price contract, in order to investigate the influence of the altruistic preferences for the decisions and coordination of the low-carbon supply chain. Some important conclusions are found through the establishment of model and numerical analysis： the retailer is more willing to cooperate with the low carbon manufacturer, and the retailer’s altruistic preferences can encourage the manufacturer to invest carbon emission reduction, so the manufacturer is more willing to cooperate with the altruistic preference retailer； under the manufacturer’s pressure of carbon emission reduction, the retailer should take on the whole supply chain, not only considering his own utility, but also considering the utility of the manufacturer, and the retailer altruism should be higher than the manufacturer’s, and thus promote the supply chain system utility. However, under the wholesale price contract, whether the retailer and the manufacturer have altruistic preferences, they can’t change the coordination of the traditional supply chain, that is, the coordination of supply chain can’t be achieved.
