Abstract
The maritime emission trading system (METS) is adopted to reduce ship CO2 emissions. This paper utilizes the forming of liner alliances under the METS to further reduce ship CO2 emissions. To investigate the effectiveness of forming liner alliances on ship CO2 emission reduction, we propose a liner ship operation planning problem for a liner alliance, which determines fleet deployment, slot co-chartering and emission permit trading. A multi-objective programming model is adopted to deal with the proposed problem. By considering three liner carriers, numerical results show that, i) the total ship CO2 emission reduction rate for these three liner carriers can be up to 13.5 %, by forming the liner alliance; ii) for any of these three liner carriers, the ship CO2 emission reduction rate can be up to 10 %∼15 %, by forming the liner alliance; iii) high fuel prices help liner alliances balance the trade-off between the operational cost and ship CO2 emissions.
期刊介绍:
Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution.
We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
