Abstract: The application of blockchain technology can realize traceability of carbon footprints and improve consumer trust in corporate carbon emission data, through it requires significant investment. Focusing on a two-tier supply chain consisting of a manufacturer and a retailer, this paper explores the operational strategies of supply chain members in different scenarios, regarding whether or not to adopt blockchain technology, and analyzes its impact. The findings show that when demand is heavily sensitive to carbon reduction levels, the manufacturer’s misreporting does not negatively affect the retailer. However, when demand is less sensitive to carbon reduction, the manufacturer’s misreporting of carbon reduction levels harms the retailer’s profits, giving the retailer an incentive to invest in blockchain technology. After adopting blockchain, the manufacturer’s actual carbon reduction levels tend to be higher than when misreporting is possible. When blockchain investment costs are relatively low, both the manufacturer and the retailer can achieve higher profits. Additionally, penalty mechanisms can partially deter the manufacturer’s misreporting. However, excessively high penalties may lead to reduced motivation for carbon reduction, ultimately lowering the overall level of emission reductions.
