“…For the carbon footprint from the cradle-to-farm-gate, estimates for various studies in kilograms of CO 2 eq. per kilogram of lamb body weight were 12.9 or 51.6 for 2 Welsh case study farms (EdwardsJones et al, 2009; the high value was due mainly to specifi c peat soil N 2 O emissions), 10 for an average Irish farm system (Casey and Holden, 2005), and 8.6 in the current study. Williams et al (2008) estimated GHG emissions to a UK retail distribution center for lambs produced in the UK or NZ at 14.1 and 11.6 kg of CO 2 eq./kg of lamb product, respectively.…”

“…Using the percents of carcass per LW and of carcass after fat trim presented for beef by Dyer et al (2010a), this result was converted to 12.3 kg CO 2 e/kg LW (Figure 2). The GHG emission intensity for lamb production was found to be 12.9 kg CO 2 e/kg LW in Wales (Edwards-Jones et al, 2009) and 10.0 kg CO 2 e/kg LW for the extensive production system in Ireland (Casey & Holden, 2005). The New Zealand (NZ) results reported by Cac et al (2012) were 8.5 kg CO 2 e/kg LW.…”

<p>Sheep production in Canada is a small industry in comparison to other livestock systems. Because of the potential for expansion of the sheep industry in Canada, the GHG emissions budget of this industry was assessed in this paper. The GHG emissions from Canadian lamb production were compared with those from the Canadian beef industry using the ULICEES model. The GHG emission intensity of the Canadian lamb industry was 21% higher than lamb production in France and Wales, and 27% higher than northern England. Enteric methane accounts for more than half of the GHG emissions from sheep in Canada. The protein based GHG emission intensity is 60% to 90% higher for sheep than for beef cattle in Canada. The GHG emission intensity for sheep in Eastern Canada is higher than for sheep in Western Canada. Protein based GHG emission intensity is more sensitive to the difference between sheep and beef than LW based emission intensity. This paper demonstrated that protein based GHG emission intensity is a more meaningful indicator for comparing different livestock species than live weight (LW) based GHG emission intensity.</p>

SUMMARYCarbon footprinting is an increasingly important method of communicating the climate change impacts of food production to stakeholders. Few studies utilize empirical data collected from farms to calculate the carbon footprints of lamb and beef. Data from two farms in Wales, UK, were employed to undertake such an analysis for two system boundaries.Within a system boundary that considers the embodied greenhouse gases (GHGs) in inputs and on-farm emissions, producing 1 kg of lamb releases 1·3–4·4 kg CO2 eq/kg live weight (case study farm 1) and 1·5–4·7 kg CO2 eq/kg live weight (case study farm 2). The production of beef releases 1·5–5·3 and 1·4–4·4 kg CO2 eq/kg live weight.Within a wider system boundary that also includes GHG emissions from animals and farm soils, lamb released 8·1–31·7 and 20·3–143·5 kg CO2 eq/kg live weight on the two case study farms, and beef released 9·7–38·1 and 18·8–132·6 kg CO2 eq/kg live weight. The difference in emissions for this system boundary relates to nitrous oxides emitted from the organic soils on case study farm 2.These values overlap with nearly all other studies of GHG emissions from lamb and beef production. No direct comparisons between studies are possible due to substantial differences in the methodological approaches adopted.
