Train: ADEME 🇫🇷

💡 High-Level Description:

ADEME (French Agency for Ecological Transition) is renowned for its comprehensive methodologies concerning environmental impact assessments across various sectors. When it comes to train travel, ADEME's methodological approach is pivotal. Train travel is often hailed as one of the more eco-friendly means of transportation, but it is imperative to quantify this assertion accurately.

ADEME's methodology for train travel encompasses the entirety of a train's lifecycle, from production to disposal. It accounts for factors such as energy consumption during operations, infrastructure establishment and maintenance, and the type of energy sources used. Specific emphasis is given to the comparison of electric trains versus diesel-powered ones, highlighting the carbon emission differences. With ADEME's methodology, railway operators, policymakers, and passengers can grasp a better understanding of train travel's environmental impact and the potential routes to decrease its carbon footprint.

API Request Items

• "type": "train" (required)

• "methodology": "ADEME" (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").

• "distance_in_km": Prioritized over origin and destination. If you don't have a distance_in_km, you can use origin and destination and the distance will be automatically resolved. If you pass both distance_in_km and origin/destination, then distance_in_km will be used.

• "train_type": ADEME defaults to local_express and considers only high_speed, mainline, and local_express.

• "fuel_type": ADEME considers diesel and electricity and defaults to diesel.

• Default Values

  • "fuel_type": "diesel"

  • "train_type": "local_express"
