What Are Scrubbers?

Scrubbers are systems installed on ships to reduce sulfur emissions by “scrubbing” exhaust gases. They allow ships to comply with emission regulations while continuing to burn high-sulfur fuel.

How Do Scrubbers Work?

Scrubbers utilize water to remove pollutants from exhaust gases. The resulting polluted water, known as scrubber discharge, is released directly into the ocean.

A Loophole That Fuels Pollution

International regulations allow ships to continue burning cheap, high-sulfur fuels as long as they use scrubbers. This loophole undermines the original intent of emission regulations and shifts pollution from the air to our oceans.

of ships follow best practices by using cleaner fuels instead of relying on scrubbers.

While scrubbers clean the air, they poison our oceans. Learn how shipping companies exploit loopholes, putting profits over the environment.

Baltic Sea Case Study

A study published in Nature Sustainability examined the economic and environmental impacts of scrubber use in the Baltic Sea. The findings revealed that the adoption of scrubbers has led to a significant increase in heavy metal pollution, resulting in millions of dollars in environmental damage.

Contaminants in Aquatic and Terrestrial Environments

A study published in Environmental Science & Technology examined the impact of exhaust gas scrubber effluents from ships on the marine copepod Calanus helgolandicus.
