Abstract：Faced with the current environmental situation, and in response to the national call to reduce emissions, there are more and more manufacturers. Emission reduction supply chain is oriented to random market demand. Due to certain errors in the prediction of market demand, that is, the occurrence of risks, members of the supply chain will make risk aversion behavior. This paper established a model to analyze the influence of data quality on the decision of emission reduction, utility and social welfare of supply chain, and found that poor data quality is harmful to them. The blockchain technology has the advantage of accurately and comprehensively recording data, whichis helpful for the supply chain by improving the quality of source data and forecasting accuracy and contribute to the supply chain. The application of blockchain technology is accompanied by non-negligible cost. This paper analyzes the necessary and sufficient conditions for the application of blockchain technology. It also discusses that when blockchain technology contributes to social welfare but damages the benefit of supply chain, the government can adopt tax reduction and subsidy policies to achieve a win-win result.
