At the Arctic Frontiers conference, The Clean Arctic Alliance and Seas at Risk explored the intersection of shipping, climate change, and strategies for a sustainable future in the Arctic and globally. The Arctic region is undergoing significant transformation due to climate change, impacting shipping routes, ecosystems, and global trade.
Arctic shipping has increased significantly over the past decade, with a 37% rise in vessel numbers and most importantly, doubling their sailing time. This trend already lead to nearly doubled CO2 emissions and more than doubled black carbon emissions impacting ice melts, driving climate change itself. To address this growing environmental and socio-economic impact, a hierarchical approach to achieving zero-emission shipping is needed, starting with enhanced energy efficiency measures like regular underwater cleaning and dry-docking, which can save 6-18% fuel per voyage. The next step involves adopting wind propulsion technology, which can reduce fuel consumption by up to 30% per voyage, followed ultimately by transitioning to zero-emission fuels. While much attention is focused on alternative fuels like ammonia and hydrogen, these options face challenges of cost, scalability, and competition for green electricity resources, making the immediate implementation of energy efficiency measures and wind technology crucial for initiating both Arctic and global shipping’s transition to zero emissions.
