'Cheat Devices' On Almost 4,000 Ships Bypass Environmental Laws

The video discusses the environmental impact of open loop scrubbers used by ships to comply with UN rules. While these devices reduce air pollution, they reroute sulfur into oceans, increasing pollution and CO2 emissions. Only a few ships use closed loop scrubbers, which safely store sulfur. The discharge from open loop scrubbers contains harmful substances linked to health issues and environmental damage. Rising ocean temperatures and chemical changes threaten ecosystems. Some countries have banned scrubbers, and the IMO is reviewing regulations to mitigate these effects.
