Environmental report says world’s fleet must switch to cleaner fuels and curb smokestack pollutants

International shipping companies must curb smokestack emissions that kill up to 60,000 people a year, including 9,000 in North America, warns a study released yesterday.

Unless the world’s ocean fleet switches to cleaner fuels, the annual global toll of premature deaths will hit 84,000 within five years, says the study in the American Chemical Society journal Environmental Science & Technology….

The damage comes from sulphur-laden Bunker C oil that powers the growing number of ships in trade and tourism. The sludgy fuel is “the dregs of the oil refining process,” and has nearly 3,000 times more sulphur than the diesel fuel burned in trucks in North America and Europe, Marshall said….

The annual number of premature deaths from all outdoor air pollution is estimated to be about 800,000, the study notes. Researchers estimated the marine pollution toll by measuring the emissions from the more than 55,000 ships, then, figuring out how much they add to the total pollution in the atmosphere. Finally, they calculate the expected number of deaths from that increase….

The solution, is simple, although expensive, Marshall said: Ships, too, should be required to burn low-sulphur fuel and install scrubbing devices. Emissions of sulphur dioxide and nitrous oxide from new and existing ships must be cut by as much as 90 per cent, no later than 2015, the study states…. (Full Toronto Star Story)
