Investigates the impact of green fuels on maritime sustainability, indicating vital pathways for industry executives and regulators.
Selecting green alternative fuels is a complex decision for shipping industry executives and regulators, involving a multitude of factors such as technological feasibility, safety concerns, fuel availability, economic costs, and environmental impacts, with a particular emphasis on the temporal aspect of lifecycle analysis. Our study addresses the existing challenges in strategic lifecycle management of green fuels within the shipping sector, bridging the cognitive and practical divide for both corporate and governmental entities. By employing Lifecycle Cost-Effectiveness Analysis (LCEA), we examine the complexities of transitioning to sustainable shipping through the lens of two prominent alternative fuels: methanol derived from natural gas (MeOHng) and liquified natural gas (LNG). Our analysis incorporates recent industry developments, including CMA CGM’s transition to LNG and COSCO’s green fuel initiatives, alongside strategic green maritime policies from Shanghai and Hong Kong. We identify decision-making principles that align with the United Nations Sustainable Development Goals (SDGs), providing a framework for informed choices in the pursuit of sustainable shipping practices.
