Bulk and breakbulk emissions all modes, v3 Fuel switch, V3 Emission new endpoint, and Milk Run fuels support
9 days ago by Marine GONZALEZ
π September 2025
It may have been summer, but we clearly didnβt take much of a break βοΈ!
This release brings a packed set of updates across our APIs:
- bulk and breakbulk emissions calculations for all modes in the Shipment API v2.1.
- Expanded fuels support in the Milk Run API v2.
- Correct ECA fuel switch in the Fuel API v3.
- A brand-new Emission API in v3 collection.
- Improvements and fixes in the Vessel API.
π Overview
π± Carbon Emissions APIs
β¨ New features in /shipment/v2/report/co2
/shipment/v2/report/co2π Bulk & breakbulk emissions supported for all modes
You can now calculate emissions for bulk and breakbulk orders on any mode: sea, road, inland_water, railand air, using the /shipment/v2/report/co2.
Example of a bulk shipment including rail, sea and road legs:

New fuels in /asset/v2/run/co2
/asset/v2/run/co2Report milk run emissions with full fuel coverage
The list of fuels supported in the Run API (/asset/v2/run/co2) has been expanded to match the same set available in the Shipment API (/shipment/v2/report/co2). This update makes it possible for 3PLs, asset-based freight forwarders, and logistics providers designing milk run operations to report emissions more accurately, based on the actual fuel used.
Newly added fuels include:
CNG, LNG, HVO, BIOCNG, BIOLNG, BIODIESEL, HYDROGEN_GASEOUS_FCV, ELEC, and a wide range of biodiesel blends (B1, B2, B5, B7, B10, B20, B30, B50).
π§βπ» V3 APIs - beta
β¨ New endpoint /v3/routes/{id}/emission
/v3/routes/{id}/emissionYou can now retrieve carbon emissions for any route in v3, with the new Emissions endpoint.
This endpoint supports all route types (shortest, historical, schedule, and proforma).
βοΈ How it works
- Request a route via
/v3/routes.
β Youβll get back arouteId. - Use the
routeIdto call/v3/routes/{id}/emission.
β Youβll receive total emissions, leg-level breakdowns, and intensity values.
This flow applies consistently across route types:
shortest: emissions estimated for a direct and optimized path (with or without IMO given).historical: emissions based on AIS-derived vessel traces.schedule: emissions based on upcoming carrier schedules.proforma: emissions averaged across multiple potential vessels per service per leg, with statistics (min,max,average,standardDeviation) available.
β¨ Features
- Always includes by-leg breakdowns (
wtw,wtt,ttw, andintensity). - Supports COβe only, but scalable to all pollutants in the future.
- Default: one single emissions value (
emissionPoint) returned. Forproformaroutes, it corresponds to theaverageacross vessels in the service. - Optional: detailed statistics with
?emissionType=statistics, returningmin,max,averageandstandardDeviation. Forproformaroutes, these values reflect the variation in vessel performances across the service, helping your procurement team to assess not only the emissions average but also the potential range of outcomes. For other route types, statistics do not apply (all values are equal, deviation = 0).
Example
- First, get a route via
/v3/routes:

π§ Fixes & improvements
Fixed fuel switch in ECA zones in /v3/routes/{id}/fuel
/v3/routes/{id}/fuelWhen a route enters an Emission Control Area (ECA), vessels must switch to a compliant fuel. Previously, the Fuel API was returning only one fuel grade for all routes. Weβve fixed the logic so the response now includes each fuel used with their respective totals and per-leg breakdowns.
Example:
{
"object": "fuel",
"data": {
"total": [
{
"fuelConsumption": {
"grade": "VLSFO",
"unit": "gram",
"value": 996239,

},
{
"fuelConsumption": {

}
],

{
"fuelConsumption": {

"unit": "gram",

},
"type": "fuelConsumption"
},
{
"fuelConsumption": {
"grade": "LSMDO",
"unit": "gram",
"value": 220069,
"mode": "sea"
},
"type": "fuelConsumption"
}
]
}
]
},
"properties": {
"shipment": {
"weight": 45000.0,
"reference": null,
"containerSizeTypeCode": "40HC",
"nContainers": 2.0,
"nTeu": 4.5
},
"route": "H16IFewBUNy"
}
}
NB: retrieving fuel data is only available for both schedule and historical route types (proforma and shortest route types are excluded).
π’ Vessel API suite
π§ Fixes & improvements
Improved vessel name matching in /vessel/v2/info
/vessel/v2/infoPreviously, when querying /vessel/v2/info with a vessel name, the API could return vessels that formerly had this name (in fka for "formerly known as") before the vessel that currently uses it.
Weβve updated the logic so that results now prioritize vessels with the current name first.
Example: /vessel/v2/HOOGE/info
- Before: returned first
EAGLE II(exHOOGE) before the vessel currently namedHOOGE. - Now: returns the vessel currently named
HOOGEfirst β
This makes searches more intuitive when vessels have changed names over time.

More accurate to locations in /vessel/v2/{imo}/eta
to locations in /vessel/v2/{imo}/etaWeβve improved how the API parses AIS destination fields to extract the to location.
Previously, depending on how the shipβs captain entered the string, the API sometimes picked the first locode instead of the intended last one, leading to inconsistent behavior, and incorrect to values in certain cases.
We now execute a smarter parsing of common separators (>, >>, <>, -, /, " TO ", etc.).
Examples:
destination=NLVLI>LTKLJβto=JPYOKβ (separator>correctly handled).destination=JPYOK-CAPRRβ previouslyto=JPYOKβ (separator-was not handled)- β now correctly returns
to=CAPRRβ . - see detailed example below:
vessel/v2/9290464/eta
- β now correctly returns
