Abstract

Greenhouse gas (GHG) emissions derived from ships have increased continually until 2018. International Maritime Organization (IMO) starts to adopt initiatives for reducing GHG emissions from ships since 2018. Now, by 2030 and 2020, IMO presented technical and operational steps, such as alternative fuels, propulsion and power system, hull and structure, voyage optimization, and energy management in the road map created to develop a comprehensive new strategic plan for achieving such as net zero emissions. However, stakeholders need to understand the long-term consequences of carbon reduction measures of IMO by simulating the dynamic interactions among many elements that affect emissions. In this context, modelling the dynamics that impact the system will be valuable in mitigating future GHG emissions and attaining net zero emission goals. This work aims to build a systematic strategy for developing a model that utilizes system dynamics to evaluate the possible long-term impacts of carbon reduction initiatives and laws on ships, as well as to forecast future CO2 emissions. This study specifically examines the global emissions generated by maritime vessels. The framework merely offers the dynamics and their accompanying mathematical equations as described in the existing literature. In this study, techniques for reducing GHG emissions are offered to gain a better understanding of how to treat emissions. The forthcoming study will integrate data on dynamics and IMO initiatives into the System Dynamics (SD) model to deduce strategic outcomes for reducing GHG emissions. The model offers a base for comprehensive framework for analysing the dynamics of GHG emissions in maritime sector. It also allows for forecasting future trends, evaluating policy options, and engaging stakeholders by simulating the dynamic interactions including as fuel usage, vessel features, regulatory frameworks, and technological improvements. This empowers decision-makers to navigate the complexities of sustainability and steer the shipping industry towards a greener and more resilient future.
