In April this year, a meeting of the International Maritime Organization’s Marine Environment Protection Committee (MEPC72) in London agreed to move forward on developing a ban on heavy fuel oil – for use and carriage as fuel from Arctic shipping. My colleague Dr Sian Prior and I wrote about how the world’s dirtiest shipping fuel would be banned from the Arctic – why it should be banned, and how the ban was going to take place.
Heavy fuel oil is a dirty and polluting fossil fuel accounting for 80% of marine fuel used worldwide. Around 75% of marine fuel currently carried in the Arctic is HFO. With climate change fuelling high winter temperatures and driving sea ice melt, Arctic waters are opening up to increased shipping in search of shorter transit times – and greatly increasing the risks of HFO spills.
