oil to natural gas has contributed to the decrease. The emission from gas engines
and wood combustion has increased.
The NMVOC emission in 2010 was 2.0 times the 1990 emission level. The
large increase is a result of the increased combustion of wood that is the
main source of emission. The increased consumption of natural gas in gas
engines (Figure 3.46) also contributes to the increased NMVOC emission.
The CO emission has decreased 5 % since 1990. The emission from wood
and from natural gas fuelled engines and boilers has increased whereas the
emission from gas oil has decreased. This is a result of the change of fuels
used in the sector.

The emission source category 5HVLGHQWLDO SODQWV consists of both stationary
and mobile sources. In this chapter, only stationary sources are included.
Figure 3.52 shows the time series for fuel consumption and emissions.
For residential plants, the total fuel consumption has been rather stable, and
in 2010, the consumption was 4 % higher than in 1990. However, the consumption
of gas oil has decreased since 1990 whereas the consumption of
