For the remaining part of the traffic between two Danish ports, other national
sea transport, bottom-up estimates for fuel consumption have been
calculated for the years 1995 and 1999 by Wismann (2007). These fuel consumption
estimates are used as activity data for the inventory years until
1995 and 1999 onwards. Interpolated figures are used for the inventory years
1996-1998.
The calculations use the database set up for Denmark in the Wismann (2001)
study, with actual traffic data from the Lloyd’s LMIS database (not including
ferries). The database was split into three vessel types: bulk carriers, container
ships, and general cargo ships; and five size classes: 0-1000, 1000-3000,
3000-10000, 10000-20000 and >20000 DTW. The calculations assume that
bulk carriers and container ships use heavy fuel oil, and that general cargo
ships use gas oil. For further information regarding activity data for local
ferries and other national sea transport, please refer to Winther (2008a).
The fleet activity data for regional ferries, and the fleet activity based fuel
consumption estimates for local ferries and other national sea transport replace
the fuel based activity data which originated directly from the DEA
statistics.

The activity data for military, railways, international sea transport and fishery
consists of fuel consumption information from DEA (2011). For international
sea transport, the basis is in principle fuel sold in Danish ports for vessels
with a foreign destination, as prescribed by the IPCC guidelines.
However, it must be noted that fuel sold for sailing activities between Denmark
and Greenland/Faroe Islands are reported as international in the DEA
energy statistics. Hence, for inventory purposes in order to follow the IPCC
guidelines the bottom-up fuel estimates for the ferry routes Esbjerg/Hanstholm/Hirshals-Torshavn,
and fuel reports from Royal Arctic
Line and Eim Skip is being subtracted from the fuel sales figures for international
sea transport prior to inventory fuel input.
For fisheries, the calculation methodology described by Winther (2008a) remains
fuel based. However, the input fuel data differ from the fuel sales figures
previously used. The changes are the result of further data processing
of the DEA reported gas oil sales for national sea transport and fisheries,
prior to inventory input. For years when the fleet activity estimates of fuel
consumption for national sea transport are smaller than reported fuel sold,
fuel is added to fisheries in the inventory. Conversely, lower fuel sales in relation
to bottom-up estimates for national sea transport means that fuel is
being subtracted from the original fisheries fuel sales figure in order to make
up the final fuel consumption input for fisheries.
The updated fuel consumption time series for national sea transport lead, in
turn, to changes in the energy statistics for fisheries (gas oil), industry (heavy
fuel oil), and international sea transport, so the national energy balance can
remain unchanged.
For all sectors, fuel-use figures are given in Annex 2.B.14 for 2010 in CollectER
format.
