The International Maritime Organization (IMO) has set ambitious goals for the shipping industry to achieve net zero emissions by around 2050, with interim reduction targets for 2030 and 2040. The sector, responsible for a growing share of global emissions, must transition to cleaner fuels to meet these targets. Insurers are identified as crucial players in this transition, providing coverage for ships adopting new propulsion systems and helping establish safety protocols for alternative fuels. Biofuels and hydrogen-based fuels are highlighted as key alternatives that could significantly reduce emissions. While these fuels are not yet in widespread commercial production, the potential of green and blue hydrogen offers promise for the industry's clean energy shift. Current statistics show that only a small percentage of ships in operation use clean fuels, indicating a substantial gap in meeting emissions targets. Research indicates that increasing policy ambition could drive the development and adoption of alternative fuels, potentially leading to a 50% to 80% reduction in marine emissions by 2030. Technologies like biofuels are expected to mature before 2030, with hydrogen and ammonia fuels becoming fully available by the mid-2030s. The viability of using these fuels is supported by reports from organizations like the European Maritime Safety Agency (EMSA). While challenges remain in scaling up the usage of alternative fuels in the maritime sector, the potential for significant emission reductions and the development of cleaner technologies offer a glimpse of a more sustainable future for global shipping.
