Train: CO2-emissiefactoren 🇳🇱

💡 High-Level Description

CO2-emissiefactoren, a prominent European carbon emissions database, has emerged as a significant reference point for accurate CO2 emissions values across various sectors, including train travel. With transportation being one of the significant contributors to greenhouse gas emissions, the role of precise data in facilitating informed decisions cannot be understated. This methodology provides a harmonized and robust foundation for assessing and comparing carbon footprints, ensuring that stakeholders are well-informed about the environmental implications of their actions.

For train travel, CO2-emissiefactoren adopts a holistic approach. It captures data not just from the operation of trains but also from the energy sources that power them. It considers factors like the electricity mix, efficiency of train models, and the carbon implications of infrastructure development. Such a comprehensive methodology ensures that the emissions data is reflective of the actual environmental impact, allowing for better decision-making for sustainable transport.

API Request Items

• "type": "train" (required)

• "methodology": "CO2-EMISSIEFACTOREN-NL" (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": CO2-EMISSIEFACTOREN-NL considers average and international as values and defaults to average.

• "fuel_type": CO2-EMISSIEFACTOREN-NL considers diesel, electricity, and average, with the default being average.

• "energy_scope": Values are ttw or wtw. Default value is wtw.

• Default Values

  • "train_type": "intercity"

  • "fuel_type": "average"
