wood has increased considerably (4.1 times the 1990 level). The consumption
of natural gas has also increased since 1990.
The large decrease (74 %) of SO2 emission from residential plants is mainly a
result of a change of sulphur content in gas oil since 1995. The lower sulphur
content (0.05 %) is a result of Danish tax laws (DEPA, 1998). In addition, the
consumption of gas oil has decreased and the consumption of natural gas
that results in very low SO2 emissions has increased.
The NOx emission has increased by 34 % since 1990 due to the increased
emission from wood combustion. The emission factor for wood is higher
than for gas oil.
The emission of NMVOC has increased 30 % since 1990 as a result of the increased
combustion of wood. The emission factor for wood has decreased
since 1990, but not as much as the increase in consumption of wood. The
emission factors for wood and straw are higher than for liquid or gaseous
fuels.
The CO emission has increased 49 % due to the increased use of wood that is
the main source of emission. The emission from combustion of straw has decreased
since 1990.
