The major part of the dioxin emission owe to wood combustion in the
residential sector, mainly in wood stoves and ovens without flue gas
cleaning. Wood combustion in residential plants accounts for 53 % of the
national dioxin emission in 2009. The contribution to the total dioxin
emission from the waste sector (36 % in 2009) stems from accidental fires,
especially building fires. The emission of dioxins from energy industries
owe mainly to the combustion of biomass as wood, wood waste and to a
less extend agricultural waste.

Stationary combustion accounts for 98 % of the estimated national HCB
emission in 2009. This is mainly due to combustion of municipal solid
waste in heating and power plants. The HCB emission from stationary
plants has decreased 83 % 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 264 % since 1990 due to
increasing wood consumption.

In general, considerable work is being carried out to improve the inventories.
Investigations and research carried out in Denmark and abroad
produce new results and findings which are given consideration and, to
the extent which is possible, are 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 to the relevant sectoral chapters.

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
