which is similar to values found in other
studies. In a previous summary of 7 farm-gate LCA of
beef cattle production (Rotz et al., 2013), reported carbon
footprints ranged from 9.7 to 19.2 kg CO2e/kg BW (about
17 to 31 kg CO2e/kg CW) with an average around 13 kg
CO2e/kg BW (21 kg CO2e/kg CW). Of this total, 67%
of the footprint was associated with the cow–calf phase,
which is also consistent with previous LCA
