Emission factors (EFs) ([[equation 5.1]]) are used to estimate emissions from the various energy-related sources ([[Table 5.2]]). In general, the so-called Tier 1 approach from IPCC guidelines ([[IPCC, 2006]]) is used. In the energy system, emissions are calculated by multiplying energy use fluxes with time-dependent emission factors. Changes in the emission factors represent technological improvements and end of-pipe control techniques, fuel specification standards for transport, clean-coal technologies in industry, etc. | Emission factors (EFs) ([[equation 5.1]]) are used to estimate emissions from the various energy-related sources ([[Table 5.2]]).

The calibration to the EDGAR database is not always straightforward due to differences in aggregation level. The general rule is to use weighted average emission factors in the case of aggregation. However, in those cases in which this results in incomprehensible emission factors (in particular when large differences exists between the emission factors for the underlying technologies) specific emission factors were chosen. | ||
