How important is it to include sold and purchased animals? How does this impact the overall GHG footprint?


Including sold and purchased animals (and their weights) is necessary for the correct calculation of life cycle emissions. Especially in the beef pathway, the functional unit for the livestock pathways is “live weight added” (‘total sold weight’ – ‘total purchased weight’ = total live wight added). By having no purchased or sold animals you have 0 as the denominator so it can’t calculate the functional unit.
