CO2 e-calculator

Welcome to the NYK Group e-calculator. This will help you estimate the amount of CO2 emitted during transport of cargo by sea, air and land. Just follow the five easy to use steps to make your calculation:

Step 1: Chose your type of transport (Container or Air)

Step 2: Enter an area or seaport for transport by container, or an airport for transport by air. When more than one letter is typed, possible origins will begin to be shown, and the intended origin can then be selected. Please note, however, that a calculation cannot be performed for an unlisted origin.

Step 3: Enter an area or seaport for transport by container, or an airport for transport by air. When more than one letter is typed, possible destinations will begin to be shown, and the intended destination can then be selected. Please note, however, that a calculation cannot be performed for an unlisted destination.

Step 4: For transport by container, input cargo volume by the ton or by 20-foot equivalent unit (TEU). For transport by air, input cargo volume by the kilogram. The input cargo volume should be specific to one decimal point.

Step 5: Calculate

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 for all vessels 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.
