Car: ACRISS

πŸ’‘ High‑Level 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 as estimated_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 both origin/destination and number_of_days.

    {
      "carbon_quantity": 65636,
      "carbon_unit": "gram",
      "external_reference": "string",
      "type": "car",
      "methodology": "ACRISS",
      "distance": 538.0,
      "distance_unit": "kilometer"
    }
  ]
}

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 resolve origin/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 over origin/destination and number_of_days. If both distance_in_km and origin/destination are provided, distance_in_km is used.

  • "number_of_days": integer (display name: Number‑Of‑Days), >= 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 of petrol, diesel, hev, phev, electricity. Default for ACRISS is petrol.

  • "acriss_car_type": Car classes: C (Compact), D (Compact Elite), E (Economy), F (Fullsize), G (Fullsize Elite), H (Economy Elite), I (Intermediate), J (Intermediate Elite), L (Luxury), M (Mini), N (Mini Elite), P (Premium), R (Standard Elite), S (Standard), U (Premium Elite), W (Luxury Elite), X (Special), O (Oversize). Default: E.

  • "sipp_car_type": If acriss_car_type is not passed, SQUAKE will auto‑resolve using the SIPP code. Mutually exclusive with pseudo_car_type (provide only one).

  • "pseudo_car_type": If neither acriss_car_type nor sipp_car_type are passed, SQUAKE will auto‑resolve using Pseudo code. Mutually exclusive with sipp_car_type. Allowed values: ACAR, ACGO, ACNV, ACPG, ACPR, ACRS, ADSL, AEIG, AELC, AELT, AETH, AFWD, AGRN, AHYB, AHYD, ALLB, ALLC, ALLD, ALMO, AMAN, AMCY, AMFP, AMNO, AMTO, ANIN, AOFR, APET, APUP, AREC, ASEV, ASIX, ASPC, ASPT, ASUV, ATRV, AUTO, AVAN, AWGN.


Default Values

  • "fuel_type": "petrol"

  • "acriss_car_type": "E"


Notes

  • Data quality tip: whenever possible, pass the actual distance_in_kmβ€”it yields the most accurate result. number_of_days is a convenience fallback and a coarse approximation.

  • If neither distance_in_km nor origin/destination are supplied, the API will use number_of_days (if provided) to estimate distance; otherwise the request may be insufficient to compute trip emissions.
