Adoption strategies of carbon abatement technologies in the maritime supply chain: impact of demand information sharing

With the increasing pressure of global climate change, the government and enterprises are actively taking measures to accelerate emission reduction in the shipping industry. To analyse the optimal adoption strategies of carbon abatement technologies for enterprises in a turbulent environment under the cap-and-trade scheme, we construct the Stackelberg game model in the maritime supply chain and conduct a comparative analysis of profits and carbon emissions to explore the interaction between information sharing and technology adoption. The results show: (1) the impact of information sharing on profits varies under different technological conditions, and the optimal technology adoption will change with carbon price; (2) information sharing will not change total carbon emissions but significantly reduce wasted carbon emissions; (3) considering consumer's green preference, information sharing can benefit the port and the shipping company simultaneously, forming a win–win situation. This study guides maritime supply chain members in technology adoption under market uncertainty.
