B. Remarks

The methodology used in this calculation is based on the Clean Cargo Working Group's CO2 emission calculation. The CO2 emission factor used in this calculation is not the average for all NYK vessels, but the average for all members of the CCWG.

The methodology used in this calculator for Airfreight is based on the CO2 emission formula and calculation of the data of UK Defra (Department for Environment, Food and Rural Affairs) which is released by GHG protocol.

The transport distance used in this calculation is an estimate of actual distance.

Calculations generated by this calculator have been verified by Lloyd's Register Quality Assurance Japan.

The ocean routes that this calculator uses are based on those served by the NYK Group; however, some routes for the latest service lineups may not be reflected in this system.

This calculator is not a tool for searching for the quickest routes.
