⚙️ Data models
Our Shipment API unlocks the potential of your data, delivering optimal results with the most fitting models.
The information you can provide is a crucial part of our CO₂e calculation models. Our ability to enhance data modeling depends also on your data inputs. To offer you the utmost accuracy in your carbon emissions, our methodology and powerful algorithms include:
- Terrestrial and Satellite AIS data
- Extensive base of carriers schedules
- Vessels technical and operational information
- Information on traffic separation schemes, piracy areas, and port entries
- Fuel type analysis, including emission control areas at sea (ECA/SECA)
Factors Models

Leveraging the latest GLEC and ISO standards, this model precisely computes carbon emissions for all transport modes.
Elements considered:
– Shortest feasible distance
– Emission factors per tradelanes
– Cargo characteristics (size, weight, dry or reefer, etc.)
– Fuel types (and fuel switch for emissions control areas at sea)
– Vehicule type (air, road and barge)
– For air, GLEC emission factors based on the length (short, medium, long haul) of the flight and the aircraft type (passenger, cargo or unknown)
Model names:
sfd-direct-emissionsfactors
gdc-direct-emissionsfactors
Vessel and Aircraft models
This solution returns CO₂e emissions between two locations, taking into account the exact characteristics of the requested ship to model its fuel consumption.

Elements considered:
– Shortest feasible distance
– Cargo characteristics
– For sea, fuel consumption model considers the characteristics of the vessel, fuel types, and fuel switch for emissions control areas
– For air, fuel consumption model considers take-off, landing, climbing, descent and cruising phases, and the aircraft characteristics for the allocation of the emissions (EEA/EMEP methodology and EUROCONTROL data)
Model names:
sfd-direct-imo
gdc-direct-icao
Historical model
Powered by historical AIS data, this model rebuilds vessel itineraries and calculates CO₂e emissions for past shipments at vessel, carrier, or industry levels. Missing shipment details? No problem. We combine your data with ours to estimate likely routes and vessels, delivering precise CO₂ insights.

Elements considered:
– Actual distances
– Port calls operated at a specific date for each vessel
– Connecting vessels
– Cargo characteristics
– The fuel consumption model considers the vessel's engine characteristics, fuel types, fuel switching in emissions control areas, and vessel characteristics for emissions allocation
Model name:
actual-portcall-ais
Schedules model
Built to empower shippers with data-driven carrier choices, this model calculates carrier-operated itineraries, including alliance services. For each itinerary, we compute CO₂e emissions of the vessels in service, providing comprehensive emission statistics..

Elements considered:
– Network distances
– Cargo characteristics
– Connecting vessels
– Cargo characteristics
– The fuel consumption model considers the vessel fleet on each service, vessel's engine characteristics, fuel types, fuel switching in emissions control areas, and vessel characteristics for emissions allocation
Model name:
network-portcalls-schedules
