Climate change: Arctic 'dirty oil' ban comes into force for ships
How does black carbon from HFO affect Arctic ice and snow?
Black carbon from Heavy Fuel Oil (HFO) contributes to the melting of Arctic ice and snow. When HFO is burned in ship engines, it emits black carbon, a sooty particle that absorbs sunlight and increases temperatures. When it lands on snow and ice, it darkens the surface, causing it to absorb more sunlight and accelerating the melting process. This contributes to the warming of the Arctic region and exacerbates the climate crisis.
What does Heavy Fuel Oil (HFO) primarily consist of?
Heavy Fuel Oil (HFO) primarily consists of the residual byproducts from the distillation and cracking process of petroleum. It is a thick, tar-like substance containing a high concentration of sulfur, nitrogen, and various hydrocarbon compounds, making it a polluting and viscous fuel option for marine vessels1.
Why is HFO particularly harmful in Arctic waters?
Heavy Fuel Oil (HFO) is particularly harmful in Arctic waters due to its high viscosity and persistence in the environment. When burned, it emits black carbon, which absorbs heat and accelerates the melting of snow and ice. Additionally, HFO is almost impossible to clean up if a spill occurs, and its lingering presence in colder waters threatens fragile ecosystems.
