Flight: GATE4

💡 High-Level Description:

GATE4 is a carbon emissions calculation methodology developed by Advito, tailored for the travel sector with a particular focus on flights. Embracing a holistic sustainability approach, GATE4 captures a broad range of factors to produce a detailed and accurate assessment of travel-related carbon emissions. For flights, variables such as aircraft type, passenger-to-freight ratios, carbon intensity, and the effect of radiative forcing are carefully accounted for. This comprehensive method allows organizations to accurately track emissions and devise strategies to mitigate their environmental impact.

The GATE4 methodology is ISO-certified, which adds a layer of credibility and ensures that its calculations align with international environmental management standards. By utilizing real-time data integration, it provides travel managers with actionable insights through the GATE4 Insights dashboard, covering not just air travel but also hotel stays, rail journeys, and car rentals. This enables businesses to identify opportunities to reduce emissions, optimize travel choices, and align their practices with sustainability goals. GATE4’s robust data-driven approach supports the development of science-based sustainability targets, helping organizations contribute effectively to global carbon reduction efforts.

API Request Items

• "type": "flight" (required)

• "methodology": "GATE4" (required)

• "external_reference": A unique identifier that helps you link the resulting emissions to the requested item. Especially useful if multiple items are requested since SQUAKE cannot guarantee to keep the same order. The maximum length is 128 characters.

• "number_of_travelers": Minimum value is 1. The default value is 1.

• "origin": SQUAKE will try to resolve the origin/destination regardless of its format. Ideally, for addresses use the Post standard, for airports use IATA/ICAO code (format: ^[A-Z]{3,4}$, e.g. "MUC"), for other locations used in trade and transportation use UN/LOCODE codes (format: ^[A-Z]{2}\W?[A-Z2-9]{3}$, e.g. "DEHAM"). You can also pass lat/long (format: ^[-+]?\d{1,3}\.\d{1,10}\s?,\s?[-+]?\d{1,3}\.\d{1,10}$, e.g. "+40.712,-74.006").

• "destination": SQUAKE will try to resolve the origin/destination regardless of its format. Ideally, for addresses use the Post standard, for airports use IATA/ICAO code (format: ^[A-Z]{3,4}$, e.g. "MUC"), for other locations used in trade and transportation use UN/LOCODE codes (format: ^[A-Z]{2}\W?[A-Z2-9]{3}$, e.g. "DEHAM"). You can also pass lat/long (format: ^[-+]?\d{1,3}\.\d{1,10}\s?,\s?[-+]?\d{1,3}\.\d{1,10}$, e.g. "+40.712,-74.006").

• "booking_class": If you don't pass a booking_class, then fare_class and airline are highly recommended. SQUAKE will then automatically resolve the correct booking_class. For GATE4, economy is the default.

• "aircraft_type": Aircraft type in the IATA or ICAO format.

• "fare_class": The combination of fare_class and airline is mutually exclusive with booking_class. This is a single letter, e.g., Y, J, etc.

• "airline": The IATA Designator of an airline, e.g., LH. Airline names are also supported, SQUAKE will then automatically resolve it. The combination of fare_class and airline is mutually exclusive with booking_class.

• "flight_number": Flight numbers should include the airline designator, e.g., "BA115". "115" also works with airline passed separately.

• "departure_date": The departure date in the format YYYY-MM-DD, which is aligned with ISO 8601
• "sustainable_fuels": Indicates the usage of sustainable fuels. This lowers the computed emissions in SQUAKE but is not part of the current official emissions frameworks.

• "carbon_reduction_percentage_of_total": The percentage of emissions reduction through the usage of sustainable fuel. The minimum value is 0, and the maximum value is 1. Default value is 0.
