A l l o c a t i o n w i t h i n t h e fa r m m o d u l e f or s h e e p a n d g o a t A biophysical approach shall be used for allocating upstream burdens to the different co-products for sheep and goat.
The 2006 IPCC guidelines for national GHG inventories (IPCC, 2006) contain a model for calculating energy requirements that shall be used for sheep and, as a proxy, for goats.
This model is applied in this document.
Dead animals and all the products from dead animals shall be regarded as waste and the circular footprint formula (CFF, Section 4.4.8.1) shall be applied.
In this case, however, the tracing of products from dead animals shall be allowed so this aspect can be taken into consideration in PEF studies.
It is mandatory to use the default allocation factors included in this document whenever secondary datasets are used for the life-cycle stage of farming for sheep and goats.
If company-specific data are used for this life-cycle stage, the allocation factors shall be calculated with the company-specific data using the equations provided.
The allocation factors shall be calculated as follows (45):
To calculate energy for wool (NEwool), energy for milk (NEl) and energy for meat (NEg) with company specific data, the equations included in IPPC (2006), and reported below, shall be used.
In case secondary data are used instead, the default values for the allocation factors provided in this document shall be used.
Energy for wool, NEwool
NEwool =
net energy required to produce wool, MJ day-1.
EVwool =
the energy value of each kg of wool produced (weighed after drying but before scouring), MJ kg-1.
A default value of 157 MJ kg-1 (NRC, 2007) shall be used for this estimate (46).
Productionwool =
annual wool production per sheep, kg yr-1.
Default values to be used for calculating NEwool and the resulting net energy required are reported in Table 11.
(45) The same naming as used in IPCC (2006) is used (46) The default value of 24 MJ kg-1 originally included in the IPPC document was modified into 157 MJ kg-1 following the indication of FAO - greenhouseGreenhouse gas emissions and fossil energy demand from small ruminant supply chains Guidelines for assessment (2016).
