Abstract: This paper studies the decision of the dual-channel supply chain when considering carbon emission reduction under carbon labelling system. With considering consumer’s low-carbon preference, the paper builds three models：both the manufacturer and the retailer are risk neutral, both the manufacturer and retailer are risk aversion, only manufacturer or only retailer is risk aversion. The results show that the efforts of manufacturer’s carbon emission reduction and the final sales price are both inversely proportional to the retailer's risk aversion, but the first one is directly proportional to the manufacturer's risk aversion, the latter is not always. When the manufacturer is risk neutral and retailer risk aversion, the effort of manufacturer’s carbon emission reduction is the largest, but the minimum when manufacturer is risk aversion and retailer is risk neutral. This paper also shows that the manufacturer make a decision, it must combine the degree of risk aversion and its proportion in the market demand.
