The emission of NOX, CO, TSP, lead, selenium, and zinc from production of
container glass is measured yearly from 1997 to 2009 (TSP from 2000 to 2009)
(Ardagh Glass Holmegaard, 2011). PM10 and PM2.5 are estimated from the
distribution between TSP, PM10 and PM2.5 from CEPMEIP (2003). For 1990 to
1996, emissions of arsenic, cadmium, chromium, copper, mercury and nickel
are estimated from standard emission factors and activity data. For 1997 to
2010, the energy related emissions are estimated from emission factors and
the actual energy consumption. This change in methodology results in inconsistency
in the emission trend that cannot be explained by natural factors.
Emission factors for lead, selenium, and zinc from 1990 to 1996 are estimated
by interpolation from the 1990 and 1997 figures (Illerup et al., 1999).
The emission of NH3 and TSP from the production of glass wool has been
measured yearly from 1996 to 2010 (TSP from 2000 to 2010) (Saint-Gobain
Isover, 2011). PM10 and PM2.5 are estimated from the distribution between
TSP, PM10 and PM2.5 from CEPMEIP (2003). The activity has varied between
33 600 and 41 318 tonnes glass wool from 1996 to 2008 and, with a significant
decrease in 2010 to 24 899 tonnes due to the financial crises. During the same
period, the emission decreased from approximately 300 to 108 tonne NH3.
The emissions from asphalt roofing and road paving have been estimated
from production statistics compiled by Statistics Denmark and default emission
factors presented by IPCC/Corinair. The default emission factors are
presented in Table 4.3.

The time series are presented in Table 4.2. The methodologies applied for the
different sources within 0LQHUDO SURGXFWV are considered to be consistent either
as measurements or emission factors based on the measurements. However,
not all the sources are considered to be complete regarding pollutants
and these are expected to be completed in the next inventory, either by use
of company-specific information or by application of general emission factors.
The time series for emissions from production of cement are based on measurements
combined with emissions factors based on the measurements.

The emission factors have been verified and the order of magnitude confirmed
by comparison with standard emission factors (EMEP/-CORINAIR,
2007; CEPMEIP, 2003). Detailed discussion of QA/QC can be found in Nielsen
et al. (2008).
