| The environmental impact of livestock is an important issue, and organic farming (OF) is particularly questioned about greenhouse gases (GHG) emissions. This study aims at comparing GHG emissions and non-renewable energy consumption in meat sheep production, in OF and conventional farming systems. These two criteria have been calculated ex-post on 1261 French year-farms monitored over 26 years. The functional unit used is the carcass weight and allocation between meat and wool is mass based. Regarding GHG emissions, the results show that organic farms emits 5% less GHG than conventional ones, with a higher proportion of methane and less indirect CO2 associated to less inputs use. Given the methodological difficulties, it is hard to argue if carbon... |

| We have undertaken in this work an evaluation of the greenhouse gas (GHG) emissions and the Non-Renewable Energy (NRE) consumption on a sample of 1250 farms-years, operating in sheep meat production, in either organic (OA) or conventional (CA) agriculture, over the period 1987 to 2012, based on the Life Cycle Assessment (LCA) method. There was no significant difference for NRE consumption (79.6 MJ in OA and 79.7 MJ in CA, per kg of carcass); indeed the gains in OA thanks to a lower use of chemical fertilizers and purchase of lesser concentrates feed were offset by the higher level of mechanization (here fuels and equipment). For GHG emissions, we found a significant difference of 5% beneficial to organic production systems (31.1 vs. 32.7 kg CO2 eq/kg... |
