Abstract
Shipping is a pivotal industry not only for transportation, but for the global economy. In today's globalized world, most goods are being transported by ships. However, the high utilization of maritime transport entails a negative environmental footprint. This challenge has brought greening and decarbonization at the forefront of research in the maritime literature. Despite the efforts of policy makers and relevant stakeholders, the most effective pathway to sustainability remains unclear. The pandemic has created additional complexities, making the achievement of sustainability goals even more challenging. Through a structured literature review, the aim of this study is to present the main avenues of sustainable shipping within a typology of clean fuel and clean propulsion systems. The analysis provides an assessment of the drawbacks and benefits of new solutions that may be implemented toward a greener post COVID-19 maritime industry.
