The Hamburg Sustainability Conference serves as a platform to tackle the challenge of transforming the shipping industry towards sustainability. The newly formed Alliance on Green Shipping Corridors aims to create routes where climate-neutral navigation is possible by utilizing green hydrogen and renewable fuels. Given that the shipping industry is a major contributor to global CO2 emissions, decarbonizing it through initiatives like green shipping corridors is essential for achieving climate goals. This collaborative effort involves stakeholders across the value chain, including fuel producers, shipping companies, ports, and governments. By establishing green shipping routes with access to renewable fuels produced in a climate-neutral way, the Alliance can make significant progress towards a sustainable shipping industry. Furthermore, development cooperation with countries in Africa, Asia, and Latin America presents an opportunity to promote green hydrogen production and sustainable development. By creating fair and equitable markets for hydrogen products, countries can benefit from economic growth, stable supply relationships, and opportunities for technology export.
