A team of researchers from the Finnish Meteorological Institute has gatherered data on 300,000 commercial shipping vessels from the year 2015 to draw a detailed picture of the resulting emissions. Using the global Automatic Identification System (AIS) that ships have to use for authorities to be able to track their position, the tream was able to draw a map of the pollution that shipping causes.
Particularly dangerous are multiple harbors in Asia, Singapore, Hong Kong and Shanghai being the worst. 76,000 vessels could not be tracked and would only make the numbers worse.
The team published their findings in form of a global study in Atmospheric Environment this month.
