Our methodology provides some background on how the carbon emissions are calculated when a user reports its transportation data in our Carbon Application.

Methodology

The amount of CO2 emission is calculated by the following formula:
\[ a = d*\frac{ef}{p} \]
Where:
a: the CO2 emission
d: the distance traveled (km)
ef: the emission factor
p: the number of passengers
