News reports have reported on new research showing that in one year, a single large container ship can emit cancer and asthma-causing pollutants equivalent to that of 50 million cars. The low grade bunker fuel used by the worlds 90,000 cargo ships contains up to 2,000 times the amount of sulfur compared to diesel fuel used in automobiles. The recent boom in the global trade of manufactured goods has also resulted in a new breed of super sized container ship which consume fuel not by the gallons, but by tons per hour, and shipping now accounts for 90 percent of global trade by volume.

Shipping is by far the biggest transport polluter in the world. There are 760 million cars in the world today emitting approx 78,599 tons of Sulphur Oxides (SOx) annually. The world’s 90,000 vessels burn approx 370 million tons of fuel per year emitting 20 million tons of Sulphur Oxides. That equates to 260 times more Sulphur Oxides being emitted by ships than the worlds entire car fleetOne large ship alone can generate approx 5,200 tonnes of sulphur oxide pollution in a year, meaning that 15 of the largest ships now emit as much SOx as the worlds 760 million cars.
