Conversion factors CO2 emissions
Conversion factors CO2 emissions
In order to calculate CO2 emissions, emission factors are required for each energy source to convert consumption figures into an emission level. The emission factors used for each energy source are shown in the following table. Carbon emissions are calculated in accordance with the Greenhouse Gas Standard. The operational control approach is used as the basis. Additionally, the greenhouse gases of the Kyoto Protocol are included in the calculation of CO₂ equivalents. Currently, emissions are calculated using location- and market-based methods. If the supplier provides specific emission factors, they are used to calculate emission values using the market-based method. These factors are taken from freely available literature and are based on the "CO₂ Factors Information Sheet" published by the Federal Office of Economics and Export Control.
