How the CO2 calculator works

The calculator is essentially based on the transaction data from your card payments. This data is augmented with emission factors, and a summary of the data is displayed each month in 14 categories. Your data is used to calculate the average for PostFinance customers, for display in the CO2 calculator overview, and to maintain and improve theCO2 calculator.

Your data is not disclosed to third parties. By logging in and launching the calculator, you agree to the processing of your data.
