For greater accuracy in CO₂e calculations, you can specify the fuel type from the following options.
| Fuel Type | Description |
|---|
| DIESEL | Standard diesel fuel |
| CNG | Compressed Natural Gas |
| LNG | Liquefied Natural Gas |
| HVO | Hydrotreated Vegetable Oil |
| ELEC | Electric power; calculations use local emission factors based on the origin |
| BIOLNG | Bio-based Liquefied Natural Gas |
| BIOCNG | Bio-based Compressed Natural Gas |
| BIODIESEL | Bio-based diesel fuel |
| HYDROGEN_GASEOUS_FCV | Hydrogen fuel for Fuel Cell Vehicles |
| LPG | Liquefied Petroleum Gas (for vans <3.5t in specific regions) |
| PETROL | Standard petrol fuel (for vans <3.5t in specific regions) |
| Blend | Composition |
|---|
| B1 | 99% Diesel, 1% Biodiesel |
| B2 | 98% Diesel, 2% Biodiesel |
| B5 | 95% Diesel, 5% Biodiesel |
| B7 | 93% Diesel, 7% Biodiesel |
| B10 | 90% Diesel, 10% Biodiesel |
| B20 | 80% Diesel, 20% Biodiesel |
| B30 | 70% Diesel, 30% Biodiesel |
| B50 | 50% Diesel, 50% Biodiesel |
| Fuel Type | Description |
|---|
| HFO | Heavy Fuel Oil, commonly used in large cargo ships. |
| VLSFO | Very Low Sulfur Fuel Oil, compliant with IMO 2020 sulfur regulations. |
| ULSFO | Ultra Low Sulfur Fuel Oil, with even lower sulfur content than VLSFO. |
| MDO | Marine Diesel Oil, a lighter and more refined fuel than HFO. |
| MGO | Marine Gas Oil, similar to MDO but with even lower sulfur content. |
| LNG | Liquefied Natural Gas, a lower-emission alternative fuel. |
| BIOLNG | Bio-based Liquefied Natural Gas, derived from renewable sources. |
| LSMGO | Low Sulfur Marine Gas Oil, a cleaner alternative to standard MGO. |
| METHANOL | Methanol, a clean-burning fuel with reduced emissions. |
| BIOMETHANOL | Bio-based methanol, produced from renewable feedstocks. |
| IFO380 | Intermediate Fuel Oil (IFO) with a viscosity rating of 380 centistokes. |
| LNG_CMACGM_VAS | LNG fuel variant used in CMA CGM's Value Added Services (VAS) for eco-friendly shipping. |
| UCO | Used Cooking Oil, a renewable fuel option derived from waste oils and used in Shipping Lines' Value Added Services (VAS) catalog. |
| METHANOL_COAL | Methanol derived from coal-based processes. |
| METHANOL_GAS | Methanol derived from gas-based processes. |
| METHANOL_RENEWABLES | Methanol produced entirely from renewable energy sources. |
The fuel parameter is applicable in the following APIs:
- Shipment API:
/shipment/v2/report/co2
- Run API:
/asset/v2/run/co2 (accepted values are only DIESEL, PETROL and LPG).
- 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.
- For rail mode
- ELEC calculations are available only for Europe.
