The Danish Maritime Authority is another country taking enforcement to another level. Using a drone provided by the European Maritime Safety Agency, ship emissions will be randomly tested for sulphur content. The readings from the drone will be immediately transmitted to Danish authorities who will follow up with ship if the readings indicate a level of non-compliance. The project will contribute to a more efficient enforcement of the sulphur rules, ensuring fair competition for shipping companies and less pollution from ships. The drone will operate in an area north of The Great Belt, where many large tankers pass when going to and from the Baltic Sea.
