Calculate endpoint overview

Ducky’s Calculate endpoints determine a user’s personal footprint in a given category based on personal habits and other data.

Calculate endpoints are used to estimate a user’s personal footprint based on their habits, in a quiz or survey-like interface on some website or app. Head over here to read more and test our demo footprint calculator.

It works in such a way that after entering the most basic household data, all other data are estimated based on the average values for a household in your region. This means that for an average household, the calculator can give you a reasonable indication of your climate footprint with little input (though naturally the result will always improve as more input is given). This also means you can immediately calculate how much a change in your lifestyle will reduce your climate footprint, and can make plans for a more sustainable future.

The Calculate endpoint can return the footprint either for the whole household or for an individual, controlled by the scope option (household or individual). The default is household. For the individual footprint, emissions related to the entire household (like heating) are divided between you and the rest of your household, while all other emissions are based on your personal habits, which you can enter into the calculator. This lets you show the effect of an individual's actions.
