3.2 Emissions of greenhouse gases
Emission of is calculated from the accounted energy use and does not
include storage in soils or emissions from soils and agricultural crop
burning. The reason for this is that these effects are too uncertain to include
in the scenarios, and that conversion to organic farming will only result in
minor changes (Dalgaard
et al.
2000). The
is calculated from
the number of animals (Table 13.11) and
from estimated
direct and indirect contributions (Table 13.12).
Subsequently, the emissions of greenhouse gases can be converted
to (Figure 13.2). The methane emissions are not
significantly reduced in the organic scenarios because the productions of
ruminants are sustained. In contrast, the nitrous oxide emissions are
reduced, primarily because no mineral fertilisers are used in the scenarios
for conversion to organic farming, and because emissions from crop
residues and N-leaching decay.
