to an error F28 was previously used as a representative aircraft type for the
new aircraft types CRJ9, E70, E170 and E175. However, F28 is a very old aircraft
which cannot represent these new aircraft types. Instead new fuel consumption
and emission factors have been calculated for the CRJ9, E70, E170
and E175 jets.

Refineries: Emissions of NMVOC have been changed for the years 1994-2000
and 2002-2009 according to VOC measurements carried out in 2001, as no
further information on fugitive emissions from the refineries are or will become
available for other historical years. This is the result of an extended
communication with one refinery leading to a recommendation to use
measured emissions, and not an estimated emission calculated by weighting
the measured emissions by the annual processed crude oil amount as done
in previous inventories. The fugitive emissions are more related to other
conditions than the processed amounts. The split of VOC emissions provided
by the refineries have been revised in order to apply a more similar
approach for the two refineries. For both refineries annual emissions of
NMVOC are not available, and emissions are based on the provided VOC
emissions and assumptions for the part of VOC being NMVOC and CH4, respectively.
Assumptions are based on information from the refineries and on
literature study of international proportions/conditions. In the previous inventory
CH4 was estimated as 10 % of VOC based on information from one
refinery.
Updated SO2 emissions for the years 2005-2009 provided by a refinery are
included in the inventory.
Gas distribution: Emission factors for NMVOC for town gas distribution
have been corrected for an error. Distribution of town gas is a minor source
and the recalculation is insignificant for all years (< 0.001 % of the total fugitive
NMVOC emission in 2009).
Offshore flaring: Activity data has been corrected for 2008 for two offshore
installations. The calorific value has been corrected for the whole time series
according to the average calorific value in the EU ETS reports for 2008-2010
which affects the emission factor for NOx, NMVOC, CO, particulate matter,
heavy metals, dioxin and PAHs. Further, the emission factors for CO and
NMVOC have been corrected by including a conversion from ms 3 (standard
m 3 ) to mn 3 (normal m 3 ). The activity data has been updated according to the
latest figures from the Danish Energy Agency (DEA).
