Greenland’s Port Communities Exposed to High Levels of Toxic Pollution From Shipping

Air quality screenings in Greenland's port of Ilulissat revealed sky-high pollution levels, averaging roughly 60,000 to 70,000 particles per cubic centimeter - 60 to 70 times higher than the World Health Organization's recommended safe threshold of 1,000 particles/cm3. These findings, taken between July 29th and August 7th, 2026, indicate that port workers and residents are routinely exposed to hazardous air pollution, particularly during wind conditions blowing from the port towards residential areas.

The heightened levels of toxic air pollution raise the risk of serious health issues like strokes, cardiovascular diseases, lung diseases, and cancer, potentially leading to premature mortality. Moreover, the study highlights the role of soot particles in global warming, citing them as a key contributor.

The measurements underscore the urgent need for Greenland to electrify its port equipment and implement onshore power for domestic vessels to reduce pollution and curb climate change. Though the pollution levels in other Greenlandic ports remain unknown, it is likely that the same high pollution rates will persist where port-side electrification is yet to be installed.

Furthermore, cruise ships exacerbate the issue when their engines remain on all day while anchored or docked, emitting as much toxic air pollution as 3,000-5,000 cars per second. Dr Kåre Press-Kristensen, senior advisor on air quality & climate at Green Global Future, emphasized the potential for Greenland and other Arctic nations to generate pollution-free renewable electricity (hydro, solar and/or wind) to tackle both air pollution and their reliance on volatile Middle Eastern fuel prices.

To swiftly reduce emissions at sea, ships sailing in Greenland's waters and the broader Arctic must transition to distillate fuels, such as marine gas oil, already in use by Greenland-flagged vessels. Dr Kåre Press-Kristensen proposed several measures at the International Maritime Organization (IMO) to accelerate this transition, including backing a proposal on polar fuels, prohibiting scrubber water discharges in territorial seas as recommended by OSPAR, and establishing a green corridor between Nuuk and Reykjavik to protect Arctic ecosystems.

Dr Sian Prior, Lead Advisor to the Clean Arctic Alliance, noted that while the Northeast Atlantic Emission Control Area adopted by the IMO on May 1st is a step in the right direction, it falls short in addressing black carbon emissions. Black carbon, primarily emitted by ships using traditional heavy fuel oils, contributes significantly to Arctic warming.

Both compliance methods using scrubbers or ultra-low sulphur fuel oils do not sufficiently reduce black carbon emissions, underscoring the need for cleaner maritime fuels like polar fuels to protect the Arctic.
