The emission from residential plants increased 30 % since 1990. The
NMVOC emission from wood combustion in 2010 was 2.6 times the 1990
level due to increased wood consumption. However, the emission factor has
decreased since 1990 due to installation of modern stoves and boilers with
improved combustion technology. Further the emission from straw combustion
in farmhouse boilers has decreased (76 %) over this period due to both a
decreasing emission factor and decrease in straw consumption in this source
category.
The use of wood in residential boilers and stoves was relatively low in 1998-
99 resulting in a lower emission level.
The decrease of the NMVOC emission since 2007 is a result of both a decline
of the consumption of wood in residential plants and a decreasing emission
factor for firewood combustion in residential plants. The small increase in
2010 is a result of increased wood consumption in residential plants compared
to 2009.
