The shipping industry is facing increasing pressure to reduce its environmental impact.

Achieving decarbonization goals and addressing climate challenges requires innovation and the exploration of various strategies, such as adopting cleaner energy sources and optimizing operational processes, to reduce the environmental footprint of maritime operations.
Energy efficiency and performance optimization are key areas of focus, with the use of digital tools and data analytics helping shipowners identify opportunities to reduce fuel consumption, lower emissions, and improve overall efficiency.
To support the transition toward sustainability, RINA has introduced a range of initiatives and standards. The organization collaborates with clients to develop solutions aimed at reducing greenhouse gas (GHG) emissions and advancing the shift to cleaner energy. This includes exploring alternative fuels such as liquefied natural gas (LNG), hydrogen, and methanol, as well as promoting the adoption of hybrid and electric propulsion systems.
When recommending alternative fuels for specific ship types, factors such as operational requirements, emissions reduction potential, and adaptability are considered.
• FOR OCEAN-GOING VESSELS (E.G., TANKERS, BULK CARRIERS, AND CONTAINER SHIPS): Hydrogen, methanol, ammonia, and LNG are viable options. LNG currently stands out as a transitional fuel due to its established infrastructure and ability to integrate with onboard hydrogen and pre-combustion carbon capture technologies.
• FOR SHORT-SEA SHIPPING: Electrification offers significant potential, especially for vessels on shorter routes.
Adaptability is essential, and, at this stage, shipowners should adopt flexible solutions that can accommodate future technological advancements.
Nuclear power also holds promise as a near-zero emissions energy source. Small modular reactors (SMRs) for naval propulsion could revolutionize the industry, providing a stable and reliable low-carbon energy supply. RINA has joined the Nuclear Energy Maritime Organization (NEMO) and is working with Fincantieri and newcleo to explore SMR applications for large vessels.
Digitalization is another transformative force in the maritime sector that can support sustainability. Advancements in predictive maintenance systems (PMS) and safety management systems (SMS) are set to make ship operations more efficient, proactive, and environmentally friendly. By 2030, these technologies will play a vital role in enabling greener and safer maritime operations.
However, challenges remain. High costs and technical hurdles, such as large-scale battery storage and hydrogen fuel integration, are significant barriers. Infrastructure for new fuels like ammonia, green methanol, and hydrogen also needs substantial improvement. Additionally, meeting stringent global emissions regulations is a complex and costly endeavor for shipowners.
For sustainable progress, solutions must be practical and economically viable. Increased collaboration across the supply chain will be crucial, involving shipping companies, fuel suppliers, ports, technology providers, and regulatory bodies. Aligning these efforts will drive the industry towards sustainability goals.
In conclusion, compliance with evolving regulations will continue to drive innovation, encouraging investment in technologies that exceed requirements to gain a competitive edge. While the maritime industry is on track to significantly enhance sustainability by 2030, the seas ahead are rough and time is pressing, so continued innovation and collaboration will be essential. By embracing all available options and maintaining momentum, the industry can successfully navigate the green transition and achieve long-term sustainability.
