In a significant move towards a sustainable shipping future, more than 50 leaders from various sectors of the maritime industry signed a Call to Action at COP 29 in Baku, Azerbaijan. The initiative aims to accelerate the adoption of zero-emission fuels, with a target of achieving at least 5% and striving for 10% uptake by 2030. The joint statement stresses the importance of investing in scalable zero-emission fuel pathways and calls for expedited action in increasing the uptake of zero and near-zero emissions shipping fuels, zero-emission vessels, and green hydrogen infrastructure globally. Industry leaders are gearing up for the Marine Environment Protection Committee's gathering in 2025, where regulatory frameworks will be established to achieve net-zero emissions in the maritime sector by 2050. The signatories highlight the necessity of well-defined regulations to strengthen the business case for decarbonization and drive industry momentum. To align with climate targets, the Call to Action outlines key recommendations, including the doubling of global green hydrogen production by 2030, translating to the uptake of at least 5 million tonnes of green hydrogen in the shipping sector. Developing countries are encouraged to seize the opportunity presented by decarbonization to attract investments, create jobs, and establish sustainable e-fuel supply chains. Collaboration among stakeholders, including green hydrogen producers, shipping entities, and policymakers, is deemed crucial for a successful transition to renewable fuels. The initiative also garners support from ports, financiers, and port service companies, committing to investing in hydrogen-derived fuel infrastructure. This collective effort signifies a pivotal moment in advancing the integration of zero-emission fuels in the maritime industry for a cleaner and more sustainable future.
