How does black carbon from ships affect Arctic ice?

Black carbon from ships coats glaciers and ice, reducing their ability to reflect the sun's heat. Instead, the heat is absorbed, causing the ice to melt faster and accelerating Arctic warming.

What is being done about ship emissions in the Arctic?

International regulators are considering proposals for ships in Arctic waters to use cleaner fuels that produce less pollution, specifically targeting black carbon emissions, which are currently unregulated in the region.

Why are some shipping companies avoiding Arctic routes?

Some companies are avoiding Arctic routes like the Northern Sea Route due to environmental concerns related to pollution, including black carbon, and the inherent operational dangers associated with these waters.

Arctic Ice Melts Faster Due to Ship Soot

As Arctic sea ice rapidly melts due to rising global temperatures, a surge in ship traffic is occurring on previously impassable routes. This increase in Arctic maritime activity carries a substantial environmental consequence, as black carbon, commonly known as soot, spews from vessels and intensifies the melting process.

When glaciers and ice are coated with this soot, their capacity to reflect sunlight diminishes. Instead, the heat from the sun is absorbed, contributing to the Arctic becoming the planet's fastest-warming region. This accelerated melting of Arctic sea ice can subsequently influence weather systems worldwide, creating a self-perpetuating cycle of increased warming.

International regulators are currently discussing proposals to mandate cleaner fuels for ships operating in Arctic waters, particularly focusing on reducing black carbon emissions. Despite a ban on heavy fuel oil enacted in 2024, its impact has been limited due to loopholes, with some ships permitted to continue using it until 2029. The push to reduce black carbon, a pollutant with a warming impact significantly greater than carbon dioxide, faces challenges from conflicting international interests and within Arctic nations themselves, where powerful industries like fishing can resist environmental regulations.
