The Baltic Sea, once a pristine haven for marine life, now faces an insidious threat: scrubber water. These seemingly innocuous systems, designed to clean ship exhaust gases, have become a double-edged sword.
While they reduce sulfur emissions, they also unleash a torrent of hazardous substances into the fragile marine ecosystem.
In this investigative report, we delve into the murky waters of scrubbers, revealing their true impact and the economic interests that perpetuate their use.

The Chalmers University of Technology in Sweden recently conducted a groundbreaking study that sheds light on the environmental toll of scrubbers.
Between 2014 and 2022, these exhaust gas cleaning systems discharged over 200 million cubic meters of environmentally hazardous scrubber water into the Baltic Sea.
This seemingly innocuous wash water, however, carries a heavy burden: it accounts for up to 9% of certain cancer-causing polycyclic aromatic hydrocarbons (PAHs) released into the Baltic Sea.
The socioeconomic costs of this pollution exceed €680 million (approximately $730 million), a staggering price for cleaner air aboard ships.
But here's the twist: while the marine environment suffers, shipping companies reap profits.
Scrubber investments have already been recouped for most ships, allowing them to run on cheap heavy fuel oil instead of cleaner alternatives.
It's a clear conflict of interest-private gains at the expense of one of the world's most sensitive seas. As the International Maritime Organization (IMO) grapples with the issue, the Baltic Sea remains caught in the crossfire.
Copper-Bottomed Conundrum: Antifouling Paints and the Unseen Culprit
Beyond scrubbers, another silent menace lurks beneath the waves: copper-based antifouling paints. These coatings, used to prevent marine organisms from clinging to ship hulls, contribute significantly to the Baltic Sea's copper load.
In fact, ships painted with copper-based antifouling paints account for a third of the total copper supply to the sea. The metal persists, unable to degrade, contaminating water, sediment, and soil.
As the world grapples with environmental challenges, the Baltic Sea serves as a microcosm of our choices. Scrubbers promise cleaner air, but at what cost?
And how much copper can the sea bear?
The answers lie in the depths, where ecosystems struggle against invisible foes. It's time to weigh the scales-economic gains versus ecological losses-and decide the fate of our fragile seas.
Danish Shipping Recognizes the Ban: A Step Towards Cleaner Waters
In a significant move, a broad political majority in Denmark has reached an agreement to ban the discharge of scrubber water in Danish waters.
This decision comes after years of debate and growing concern about the environmental impact of scrubbers. Let's dive deeper into the details:
The Scrubber Dilemma
Scrubbers, hailed as a solution to reduce sulfur emissions from ships, have become a common sight in maritime traffic.
However, their environmental consequences extend beyond the visible reduction in air pollution.
When exhaust gases are "washed" using seawater, contaminants are trapped, leading to the release of hazardous substances into the marine environment.
The Baltic Sea, already burdened by pollution, bears the brunt of this hidden cost.
A Sensible Phase-In Period
The ban on ships' discharge of scrubber water will apply in the Danish territorial sea, 12 nautical miles (about 22 km) from the coast.
Shipping companies that have invested in complying with the rules and reducing their sulfur emissions with scrubbers will have time to adapt to a new reality.
Nina Porst, Director of Climate, Environment, and Safety at Danish Shipping, emphasizes the need for robust enforcement to ensure a level playing field for Danish shipping companies.
Looking Ahead: Regional and Global Impact
Denmark aims to work for a similar ban in the Baltic Sea and North Sea through the regional sea conventions HELCOM and OSPAR, with a view to regulation under IMO auspices.
As the ban takes effect, the marine environment breathes a sigh of relief.
But the battle against scrubbers and copper paints continues, echoing across the waves-a call to protect our seas for generations to come.
Conclusion
The Baltic Sea's battle against scrubbers and copper paints is far from over. As authorities deliberate, the marine environment hangs in the balance.
Will we prioritize profits or protect our seas? The choice is ours, and the consequences ripple far beyond the horizon
