Run API: /asset/v2/run/co2 (accepted values are only DIESEL, PETROL and LPG).
Notes:
If no fuel is specified: the API defaults to the vessel’s least green fuel option, ensuring compliance with GLEC’s conservative approach for emissions assumptions.
For sea mode:
Fuel input requires a vessel specification (name or imo) for accurate emissions modeling.
Dual-fuel vessels: user input prevails if the vessel can operate on the specified fuel (e.g., ULSFO instead of HFO, or LNG instead of HFO for LNG-compatible ships).
Compatibility rules: the vessel’s fuel configuration takes precedence when the input fuel is incompatible (e.g., LNG or Methanol cannot be used on a vessel designed for HFO only). Fuel compatibility is verified using our vessel database, which includes detailed vessels configurations.
HFO, VLSFO, and ULSFO comply with IMO sulfur regulations and are commonly used in traditional maritime shipping.
For road mode:
ELEC calculations use local emission factors based on the origin region.
LPG and PETROL are available for vans weighing less than 3.5t in Europe, South America, Africa, and Asia.
