The Emission Calculator calculates the estimated amount of CO2/NOX/SOX/PM10 for a port to port transport string of the DAL service package. The calculation methodology was established according to MEPC.1/Circ.684 "Guidelines for voluntary use of the Ship Energy Efficiency Operational Indicator (EEOI)" and is based upon operational voyage data. The ocean routes distance is based on the routes served by DAL. However, some routes for the latest service line-ups may not be reflected in the tool. The calculated emissions may also deviate from real emissions due to actual sailing and operational conditions. The calculations generated by the Emission Calculator should be used at your own discretion.
