Car: ACRISS
π‘ HighβLevel Description
ACRISS (Association of Car Rental Industry Systems Standards) is known for its rental car coding standards and, increasingly, for methodologies addressing environmental impacts in automotive travel.
The ACRISS car methodology differentiates emissions by vehicle class, fuel/energy type, and usage patterns (e.g., distance, trip context), acknowledging that a compact city car differs markedly from a large SUV.
It incorporates vehicle specifications, driving behavior assumptions, and maintenance practices to estimate carbon emissions.
The approach reflects the market shift toward EVs, HEVs, and PHEVs, and is updated periodically to remain aligned with industry standards and technology advances.
Sample API Requests
A. Route-based request (origin/destination or explicit distance)
{
"expand": ["items"],
"items": [
{
"type": "car",
"methodology": "ACRISS",
"external_reference": "string",
"origin": "Frankfurt am Main, Germany",
"destination": "Berlin, Germany",
"fuel_type": "diesel",
"acriss_car_type": "C"
}
]
}
B. Duration-based request (fallback when distance is unknown)
When the trip distance is unknown, you may pass
number_of_days
. The API will estimate the distance asestimated_distance_in_km = number_of_days * 60
.
{
"expand": ["items"],
"items": [
{
"type": "car",
"methodology": "ACRISS",
"external_reference": "string",
"fuel_type": "diesel",
"acriss_car_type": "C",
"number_of_days": 5
}
]
}
Precedence rule: If
distance_in_km
is provided, it will be used and takes priority over bothorigin
/destination
andnumber_of_days
.
Sample API Response

}
API Request Items
"type"
:"car"
(required)."methodology"
:"ACRISS"
(required)."external_reference"
: A unique identifier (max 128 chars) to link the result to your item (useful for multi-item requests where order is not guaranteed)."origin"
: SQUAKE will try to resolveorigin
/destination
regardless of format. Prefer:Addresses: postal standard.
Airports: IATA/ICAO
^[A-Z]{3,4}$
(e.g.,"MUC"
).Trade/transport locations: UN/LOCODE
^[A-Z]{2}\W?[A-Z2-9]{3}$
(e.g.,"DEHAM"
).Coordinates:
^[-+]?\\d{1,3}\\.\\d{1,10}\\s?,\\s?[-+]?\\d{1,3}\\.\\d{1,10}$
(e.g.,"+40.712,-74.006"
).
"destination"
: Same formats and rules as"origin"
."distance_in_km"
: If present, takes priority overorigin
/destination
andnumber_of_days
. If bothdistance_in_km
andorigin
/destination
are provided,distance_in_km
is used."number_of_days"
: integer (display name: NumberβOfβDays), >= 1.Use when trip distance is unknown.
The API estimates distance as:
estimated_distance_in_km = number_of_days * 60
.Precedence:
distance_in_km
>origin/destination
>number_of_days
(fallback).
"fuel_type"
: One ofpetrol

."sipp_car_type"
: Ifacriss_car_type
is not passed, SQUAKE will autoβresolve using the SIPP code. Mutually exclusive withpseudo_car_type
(provide only one)."pseudo_car_type"
: If neitheracriss_car_type
norsipp_car_type
are passed, SQUAKE will autoβresolve using Pseudo code. Mutually exclusive withsipp_car_type

Notes
Data quality tip: whenever possible, pass the actual
distance_in_km
βit yields the most accurate result.number_of_days
is a convenience fallback and a coarse approximation.If neither
distance_in_km
nororigin
/destination
are supplied, the API will usenumber_of_days
(if provided) to estimate distance; otherwise the request may be insufficient to compute trip emissions.
