🌐Travel

Traveling, whether for leisure, business, or necessity, plays a significant role in our daily lives. From flights and car rentals to accommodations, each step of a journey leaves an environmental footprint. With growing awareness of climate change, understanding and managing the carbon emissions associated with travel has become crucial. Whether you're planning a round-the-world trip or a simple weekend getaway, having insights into the emissions generated by each activity allows for better choices and a more sustainable approach to travel.

The SQUAKE platform offers the ability to calculate carbon emissions across various travel-related activities. These calculations provide transparency and foster sustainability by encouraging travelers to offset their emissions or choose greener alternatives. Whether you're flying internationally, renting a car, staying at a hotel, or taking a ferry, SQUAKE’s methodology helps in understanding the environmental impact of your journey.

The calculations endpoint is used to calculate carbon emissions for one or multiple activities. For example, you can compute the carbon footprint of a journey consisting of a return flight, two cab rides, and a hotel stay, by passing all activities in the items array. By including the string literal "items" in the "expand" array, you can retrieve emissions for each item separately in addition to the total carbon quantity.

This is a low-latency endpoint. Note that SQUAKE does not provide a unique identifier for any calculation results through this endpoint. You must quote a price on the pricing endpoint to purchase compensation for your carbon emissions.

Some data sets are extensive and are documented separately.

Request Format Content Type: application/json

Body

• expand array[string] If you choose to expand on, for example, "items", SQUAKE returns emissions per each item separately (in addition to a total value). Value: "items"

• carbon_unit string SQUAKE uses The International System of Units (SI), commonly referred to as the "metric system". Possible Values: "tonne", "kilogram", or "gram"

• distance_unit string SQUAKE uses common distance units. Possible Values: "meter", "kilometer", "feet", "mile", or "nautical_mile" Default value: "kilometer"
