gas oil, natural gas and wood in residential plants. The emissions from
energy industries have decreased by 77 % from 1985 to 2009. In the
same period, the total emission decreased by 56 %. The reduction is due
to the increasing use of catalyst cars and installation of low-NOX burners
and denitrifying units in power plants and district heating plants.

Almost all atmospheric emissions of NH3 result from agricultural activities.
Only a minor fraction originates from road transport (2 %). This
fraction is, however, increasing due to increasing use of catalyst cars.
The major part of the emission from agriculture stems from livestock
manure (83 %) and the largest losses of ammonia occur during the handling
of the manure in stables and in field application. Other contributions
come from use of mineral fertilisers (6 %), N-excretion on pasture
range and paddock (3 %), sewage sludge used as fertiliser, crops and
ammonia used for straw treatment (7 %) and field burning (less than 1
%). The total ammonia emission decreased by 36 % from 1985 to 2009.
This is due to the active national environmental policy efforts over the
past twenty years. Due to the action plans for the aquatic environment
and the Ammonia Action Plan, a series of measures to prevent loss of
nitrogen in agricultural production has been initiated. The measures
have included demands for improved utilisation of nitrogen in livestock
manure, a ban against application of livestock manure in winter, prohibition
of broadspreading of manure, requirements for establishment of
catch crops, regulation of the number of livestock pr hectare and a ceiling
for the supply of nitrogen to crops. As a result, despite an increase
in the production of pigs and poultry, the ammonia emission has been
reduced considerably.
