The maritime industry, crucial for global trade, is addressing its significant greenhouse gas emissions. The Nordic countries are at the forefront of decarbonizing maritime transport, leveraging innovative and sustainable practices. Strategies include fuel switching to methanol and biofuels, electrification, wind-assisted ship propulsion, and on-board carbon capture, emphasizing collaboration among various stakeholders. Nordic nations have set ambitious GHG reduction targets and are supported by international regulations like the IMO's net-zero emissions goal for 2050. The EU's 'Fit for 55' package integrates maritime transport into emissions trading and mandates onshore power supply by 2030. Each Nordic country has tailored strategies, with Norway focusing on zero-emission ferries and hydrogen hubs, Denmark on sustainable fuels like ammonia, and Sweden and Finland on electrification and biofuels. The Nordic region aims to become the world's most integrated and sustainable by 2030, with a specific emphasis on decarbonizing the maritime sector. Innovative solutions in the Nordics include extensive electrification efforts in Norway, with battery-powered ships and hydrogen-powered vessels operational. Exploration of ammonia as an alternative fuel is also ongoing, although safety and regulatory challenges persist. Collaborative initiatives aim to drive joint innovation and sustainability in the maritime industry, showcasing the Nordics' leadership in energy transition.
