US ship freight
[/transport/ship/generic/freight/ghgp/us]
The category /transport/ship/generic/freight/ghgp/other contains data on the greenhouse gas emissions associated with ship transported freight in the US, sourced from the World Resources Institute Greenhouse Gas Protocol (GHGP).
To use this category, select the type of ship using the type drill down option, and specify the size using the size drill option.
Next, specify the distance and mass of the freight transported by setting the distance and mass profile item values. The returned value represents the mass of CO2 emitted in association with the specified freighting. In the GHGP subcategories the returned value also incorporates CH4 and N2O emissions, all expressed together as the mass of CO2 which would provide an equivalent global warming effect.
