Car: ACRISS

💡 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 without audit mode (origin/destination or explicit distance)

{
  "expand": ["items"],
  "items": [
    {
      "audit": false,
      "type": "car",
      "methodology": "ACRISS",
      "external_reference": "string",
      "origin": "Frankfurt am Main, Germany",
      "destination": "Berlin, Germany",
      "fuel_type": "diesel",
      "acriss_car_type": "C"
    }
  ]
}

B. Route-based request with audit mode (for finalized/post-booking calculations)

{
  "expand": ["items"],
  "audit_for": "<Auditable Entity ID>",
  "items": [
    {
      "audit": true,
      "type": "car",
      "methodology": "ACRISS",
      "external_reference": "string",
      "origin": "Frankfurt am Main, Germany",
      "destination": "Berlin, Germany",
      "fuel_type": "diesel",
      "acriss_car_type": "C"
    }
  ]
}

Note: audit_for is optional. Provide when calculating on behalf of a specific Auditable entity; otherwise omit.

C. 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": [
    {
      "audit": false,
      "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.

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.

• "audit": boolean (optional). Set to true to create immutable audit records for finalized calculations. Must be enabled for your account.

Default Values

• "fuel_type": "petrol"

• "acriss_car_type": "E"

---

Notes

• Data quality tip: whenever possible, pass the actual distance_in_km—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.
