Stationary combustion accounts <strong>for</strong> 39 % of the national CO emission. Table<br />

3.8 presents the CO emission inventory <strong>for</strong> stationary combustion subcategories.<br />

Residential plants are the largest emission source, accounting <strong>for</strong> 84 % of the<br />

emission. Wood combustion accounts <strong>for</strong> 90 % of the emission from residential<br />

plants, see Figure 3.13. This is in spite of the fact that the fuel consumption<br />

share is only 42 %. Combustion of straw is also a considerable emission<br />

source whereas the emission from other fuels used in residential plants is<br />

almost negligible.<br />

Time series <strong>for</strong> CO emission from stationary combustion are shown in Figure<br />

3.14. The emission has increased by 17 % from 1990. The time series <strong>for</strong><br />

CO from stationary combustion plants follow the time series <strong>for</strong> CO emission<br />

from residential plants. The decreased wood consumption in residential<br />

plants in 2007-2009 and the increase in 2010 is reflected in the time series <strong>for</strong><br />

CO emission.<br />

The consumption of wood in residential plants in 2010 was 4.4 times the<br />

1990 level. However, the CO emission factor <strong>for</strong> wood has decreased since<br />

1990 causing the CO emission from wood combustion in residential plants in<br />

2010 to be only 3.0 times the 1990 level. Both straw consumption and CO<br />

emission factor <strong>for</strong> residential plants have decreased since 1990.<br />
