Optional data input methods
Data may be registered on the vessels via the noon- and port-reports in DNV Navigator product, or via a specific input form. The xml-files are sent via mail to the server and imported into the central database. With internet connection, the users may also use the web registration tool directly.

Emissions to air - CO₂ Index for shipping
The shipping industry is facing strong international pressure to reduce its CO₂, NO_x and SO_x emissions. Also economic instruments are being established on national leve. In this respect, the guideline proposed by the IMO for a standardised CO₂ index is a suitable measure to use (MEPC Circ./471). The index is calculated on the basis of consumed fuel, transported cargo and distance sailed, and carbon emission factors.

Computed index values can be compared for a fleet, sister ships or specific periods of time and eventually be used to minimise emissions from transport. This benchmarking approach can contribute to drive the shipping industry towards higher energy efficiency and lower emissions.
