Big polluters: One massive container ship equals 50 million cars
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 ...

Asphalt has to be kept about 180 deg F in the tank farm if I remember, but it's been many years.
