Each year’s total is the sum of each layer’s running loss, soak loss and diurnal
emissions.

The calculated fuel consumption in COPERT IV must equal the statistical
fuel sale totals according to the UNFCCC and UNECE emissions reporting
format. The statistical fuel sales for road transport are derived from the Danish
Energy Authority data (see DEA, 2011). The DEA data are further processed
for gasoline in order to account for e.g. non road and recreational craft
fuel consumption, which are not directly stated in the statistics, please refer
to paragraph 1.1.4 for further information regarding the transformation of
DEA fuel data.
The standard approach to achieve a fuel balance in annual emission inventories
is to multiply the annual mileage with a fuel balance factor derived as
the ratio between simulated and statistical fuel figures for gasoline and diesel,
respectively. This method is also used in the present model.
