Flights DEPRECATEDDEPRECATED
In addition to direct calculation of emissions per passenger-kilometer, passenger-mile, tonne-kilometer or ton-mile, Climatiq makes endpoints available for calculating emissions based on departure and arrival airports. The API will automatically select an appropriate emission factor; a specific ID can be selected to override this.
⚠️
The flights endpoint is deprecated and will be removed in a future version. Use the new travel feature instead.
POST Calculate total estimated emissions produced by passenger flights between the specified airports

The following parameters can be defined as JSON-encoded object in a body.
| Attribute | Required |
|---|---|
| legs array An array of one or more legs in a flight | required |
Flight legs are the constituent elements of a given flight from one location to another; e.g. a flight from Berlin to New York JFK might require 2 legs of Berlin to Amsterdam and Amsterdam to New York JFK
| Leg Attributes | Required | Default |
|---|---|---|
| from string Start of flight leg, expressed in an IATA code (opens in a new tab) | required | |
| to string End of flight leg, expressed in an IATA code (opens in a new tab) | required | |
| passengers int How many passengers are on the flight? | optional | 1 |
| class string Which class the flight was on. Allowed values are unknown, economy, business, first | optional | unknown |
| year number The year that the travel took place. Climatiq will pick emission factors that is as close to the supplied year as possible. | optional | The current year |
| emission_factor Selector This endpoint will automatically pick the highest emission factor which is eligible for the flight. If you want to override the automatic emission factor selection you can provide a selector. You are then fully responsible for emission factor selection. The selector must end up selecting an emission factor that supports the PassengerOverDistance unit. | optional |
# First class trip from Berlin to Amsterdam for two passengers.# Followed by a trip from Amsterdam to New York JFK for two passengers in economy class.curl --request POST \ --url https://beta4.api.climatiq.io/travel/flights \ --header 'Authorization: Bearer API_KEY' \ --data '{ "legs": [ { "from": "BER", "to": "AMS", "passengers": 2, "class": "first" }, { "from": "AMS", "to": "JFK", "passengers": 2, "class": "economy" } ] }'Response
The response includes the total emissions for the trip in kgCO2e, and the emissions for each leg of the trip.
| Attribute |
|---|
| co2e number Total carbon dioxide equivalent for entire trip. |
| co2e_unit string The unit in which the co2e field is expressed. |
| legs [Estimations] List of estimations, one for each leg in the trip. These are returned in the same order as the flight legs. |
| wtt_legs [Estimations] List of estimations for the co2e associated with procuring and transportation the fuel (the well-to-tank emissions) These are returned in the same order as the flight legs. If you supply your own selector for a leg via the emission_factor parameter, this list will contain null for that leg. |
