4. Conclusions and recommendations
GHG emissions from wool production from both sub-clover and
mixed pasture plots has been found to have the largest GHG
emissions (i.e 16.7 kg CO2-eq per kg), which is about 3 times higher
than the GHG emissions of the sheep meat production from these
plots. The emission of CH4 accounted for a significant portion of
GHG emissions from sheep meat and wool production in mixed
pasture and sub-clover plots, whilst N2O is the major greenhouse
gas emitted from wheat and wool production from the wheat plot.
CO2 accounted for an insignificant portion of the total emissions
during the life cycle of these three products when compared with
N2O and CH4. The on-farm stage accounted for a significant portion
of total GHG emissions from wheat, sheep meat and wool
production in sub-clover wheat and mixed pasture plots.
