The maritime industry transports over 80% of goods worldwide and is essential to the deployment of climate technologies. At present, the industry contributes approximately 2 to 3% of global emissions, but this figure is projected to grow without major changes to the industry and its ancillary services. However, decarbonizing the maritime industry is unusually challenging. As the president of Marine and executive vice president at Wärtsilä, Roger Holm’s team helps power one out of every three ships worldwide. In light of new EU regulations and the International Maritime Organization’s goal of net neutral carbon emissions by 2050, Wärtsilä is now focused on solving the decarbonization riddle for clients that operate ships that can last for decades and need to be able to adapt to a wide range of infrastructure and fuels in ports. In this episode, Roger Holm chats with Hilary Langer and shares why Wärtsilä approaches maritime decarbonization at the systems level, why clients are increasingly focused on sustainability, and where he sees the greatest potential for carbon and cost savings.
