Value factors for electric power and heat generation are determined by using emission factors from the German Environment Agency to assess the direct and indirect greenhouse gas and air pollutant emissions per kilowatt hour for different energy sources. These emission factors are weighted with the value factors for GHG and air pollutant emissions. The value factors in the tables below are averages, following a generic, national-level approach.
Two value factors are provided for each energy source – one using a 0 percent Pure Rate of Time Preference (PRTP) (corresponds to an equal weighting of current and future welfare) and one using a 1 percent PRTP (corresponds to a higher weight on current welfare) for GHG emissions.
Greenhouse gas and air pollution related environmental impacts from power generation strongly depend on energy source. Value factors range from 0.43 €-cent/kWh to 107 €-cent/kWh.
