Update of the navigation emission estimates in ports both at national and local level

The report contains the results of a project aimed at collecting data on navigation traffic in a few Italian harbors. A model has been used to calculate emissions estimate. A huge amount of data is necessary to perform a precise evaluation of emissions from the shipping sector.

A detailed data base, which collects the times requested by each ship both in maneuvering and hoteling phase, has been created to this purpose. The emission factors thus obtained will allow annual updates of the National Inventory Report estimates.
