Denmark's National Inventory Report 2005 - Submitted under the ...

• This years data delivery agreements with institutes/organisations are established to ensure
that the necessary agricultural input data is available.
6.8 Recalculation
Compared to the previous emission inventory (submission 2002) few changes are made. These
changes increase the total GHG emission from the agricultural sector with less than 0.5 % (Table
6.29).

The changes are summarized below. There have been no changes in the methodology used to calculate
the emissions.
• The N 2 O emission from Manure Management (CRF Table 4s2, activity 4.B) now includes N 2 O
reduction from biogas treated slurry. It has almost no effect on the total N 2 O emission.
• The activity data related to the emission from crop residue has been updated. The change has
increased the N 2 O emission from this source for all years with 2-5%. There is almost no effect
on the total N 2 O emission.
• The CH 4 emission (CRF table 4s1, activities 4.A and 4.B) has increased for all years from 1990 to
2002 but less than 1% of the total CH 4 . The recalculation is due to small changes in slaughtering
data for calves (bull). This does not effect the number of “Other Cattle”, which is given from
the Statistics Denmark. The change has a slight effect on both the total emission and the IEF.
6.9 Planned improvements
The Danish emission inventory for the agricultural sector mainly meets the request as set in the
IPCC Good Practice Guidance. Nevertheless, working out a QA/QC plan and estimation of uncertainties
are two important issues in which the inventory still needs to be improved. Further, the
review team has pointed out the needs for more detailed documentation and explanation for some
specific emission sources where national values are used in the calculation.
The QA/QC plan for the agricultural sector is still under development, but some measures have
been formulated as general lines for the further work. The objectives for the quality planning, as
given in the IPCC Good Practice Guidance, are to improve the transparency, consistency, comparability,
completeness and confidence. For the agricultural sector this work will be followed up be
a more specific description for a QC and QA procedure in according to the principle lines mentioned
below:
• Review of existing data structure
- complete and detailed overview from raw input data and emission
factor to the total emission estimate
