The emission source category $JULFXOWXUH IRUHVWU\ consists of both stationary
and mobile sources. In this chapter, only stationary sources are included.
Figure 3.53 shows the time series for fuel consumption and emissions.
For plants in agriculture/forestry, the fuel consumption has decreased 31 %
since 1990. A remarkable decrease of fuel consumption has taken place since
year 2000.
The type of fuel that has been applied has changed since 1990. In the years
1994-2004, the consumption of natural gas was high, but in recent years, the
consumption decreased again. A large part of the natural gas consumption
has been applied in gas engines (Figure 3.46). Most CHP plants in agriculture/forestry
based on gas engines came in operation in 1995-1999. The decrease
in later years is a result of the liberalisation of the electricity market.
The consumption of straw has decreased since 1990. The consumption of
both residual oil and gas oil has increased after 1990 but has decreased again
in recent years.
The SO2 emission was 68 % lower in 2010 than in 1990. The emission decreased
mainly in the years 1996-2002. The main emission sources are coal,
residual oil and straw.
The emission of NOx was 41 % lower in 2010 than in 1990.
The emission of NMVOC has decreased 41 % since 1990. The major emission
source is combustion of straw. The consumption of straw has decreased
since 1990. The emission from gas engines has increased mainly due to increased
fuel consumption.
The CO emission has decreased 72 % since 1990. The major emission source
is combustion of straw. In addition to the decrease of straw consumption,
the emission factor for straw has also decreased since 1990.
