Emission reduction technologies for shipping supply chains under carbon tax with knowledge sharing

Abstract

In response to the gradually increasing pressures of global climate change, governments and enterprises around the world are taking proactive measures to encourage the shipping industry to reduce emissions. Meanwhile, knowledge sharing plays an important role in uncertain market environment and has a profound impact on the development of emission reduction strategies. This paper constructs a shipping supply chain consisting of the port and liner company, and explores the impact of carbon tax policies on carbon emission reduction technologies. By using the Stackelberg game model, the benefits of port and liner company are compared and analyzed in order to explore the interrelationship between knowledge sharing and the use of emission reduction technologies. The results of the study show that: (1) Under the conditions of different emission reduction technologies, the state of knowledge sharing has a significant impact on carbon emission benefits, and the determination of the optimal reduction technology is affected by both knowledge sharing and carbon tax rate. (2) Although the impact of knowledge sharing on total carbon footprint is not obvious, it can effectively reduce the redundant carbon footprint. (3) The inclusion of consumers’ green preferences and knowledge sharing in the model is conducive to the port and liner company to realize mutual benefits and win-win situation. The findings of this paper provide a reference for the adoption of emission reduction technologies by shipping supply chain stakeholders under market uncertainty.
