Researchers from MIT and Georgia Tech have determined that burning heavy fuel oil with scrubbers in the open ocean can be as environmentally friendly as using low-sulfur fuels. Lead author Patricia Stathatou emphasized the importance of using objective data to compare options accurately. The study revealed that scrubbers reduce sulfur dioxide emissions by 97%.
Scrubbers on ships may reduce air pollution, but they transfer toxic pollutants into the oceans. Scientific evidence shows harmful effects on marine life, especially endangered species. Cruise ships are major contributors to scrubber pollution, discharging toxic waste daily. Cleaner fuels are a better solution, but government intervention is needed to protect our oceans.
The Danish government has announced a ban on discharging scrubber water from ships into Danish waters starting July 1, 2025. Scrubber use has been linked to harmful substances in seawater. Ships must transition to low-sulfur fuel or closed scrubbers by 2025. Denmark aims to regulate maritime areas with regional conventions and push for international regulations.
