Biochar Needed: The total amount of biochar in tonnes needed for the application on the selected volume.

Biochar Cost: The expected total cost in € for the needed amount of biochar of the selected type.

CO₂e emissions: This adjusts the tonnes of biochar by the correction rate for the application in a construction material (where more than 95% is exected to remain after 100 years), and then multiplies it by 3.67 to give the weight of CO₂ (When two oxygen atoms bind to a carbon atom, the combined mass of the carbondioxide molecule is 3.67 times that of the carbon atom on its own.

CO₂e emissions reduction by reduced hard material usage: Assumption: In this example, a hard construction material is still being used, which will generate emissions. No additional savings are assumed.
