How exactly is the carbon footprint calculated?
TheCO2 footprint is calculated with the help of so-calledCO2 factors. Ideally, each product or activity has such a factor, which has been scientifically determined and indicates how many kilograms ofCO2 equivalents are emitted through the use of the product or the performance of the activity.
For example: According to a source from the Federal Environment Agency, a medium-sized car produces 0.25 kg ofCO2 over a distance of one kilometer. Based on this, yourCO2 footprint is determined using your information on the number of vehicles you have and your activities with them (kilometers driven on the way to work or school, on trips or to business appointments).
