Wood combustion in residential plants accounts for 64 % of the national dioxin
emission in 2010. The contribution to the total dioxin emission from the
waste sector (24 % in 2010) stems from accidental fires, especially building
fires. The emission of dioxins from energy industries owes mainly to the
combustion of biomass such as wood, wood waste and to a less extend agricultural
waste.

Stationary combustion accounts for 98 % of the estimated national Hexachlorobenzene
(HCB) emission in 2010. This is mainly due to combustion of
municipal solid waste in heating and power plants. The HCB emission from
stationary plants has decreased 81 % since 1990 mainly due to improved flue
gas cleaning in MSW incineration plants. Wood combustion in households is
an important source, too, and has increased by 302 % since 1990 due to increasing
wood consumption.

Investigations and research carried out in Denmark and abroad produce
new results and findings, which are given consideration and, to the extent
possible, included as the basis for emission estimates and as data in the inventory
databases. Furthermore, the updates of the EMEP/CORINAIR
guidebook (Now the EMEP/EEA Guidebook), and the work of the Task
Force on Emission Inventories and its expert panels are followed closely in
order to be able to incorporate the best scientific information as the basis for
the inventories.
The implementation of new results in inventories is made in a way so that
improvements, as far as possible, better reflect Danish conditions and circumstances.
This is in accordance with good practice. Furthermore, efforts
are made to involve as many experts as possible in the reasoning, justification
and feasibility of implementation of improvements.
In improving the inventories, care is taken to consider implementation of
improvements for the whole time series of inventories to make it consistent.
Such efforts lead to recalculation of previously submitted inventories. This
submission includes recalculated inventories for the whole time series. The
reasoning for the recalculations performed is to be found in the sectoral
chapters of this report. The text below focuses on recalculations, in general,
and further serves as an overview and summary of the relevant text in the
sectoral chapters. For sector specific planned improvements please also refer

Improvements and updates of the Danish energy statistics are made regularly
by the producer of the statistics, the Danish Energy Agency (DEA). In
close cooperation with the DEA, these improvements and updates are reflected
in the emission inventory for the energy sector. The Danish energy
statistics have, for the most part, been aggregated to the SNAP categorisation.
This, however, does not include energy statistics for fuel consumption
data for specific industries.
The inventories are still being improved through work to increase the number
of large point sources, e.g. power plants, included in the databases as in-
