The Guardian has 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% of global trade by volume.
...
Not only are shipbuilders resetting the world record for size on a regular basis but so are the diesel engines that propel them. One of the eight longest container ships in the world, the 1,300 ft Emma Mærsk also has the world's largest reciprocating engine. At five storeys tall and weighing 2300 tonnes, this 14 cylinder turbocharged two-stroke monster puts out 84.4 MW (114,800 hp) - up to 90MW when the motor's waste heat recovery system is taken into account. These mammoth engines consume approx 16 tons of fuel per hour or 380 tons per day while at sea.
