Review on LCA approaches and GHG mitigation actions in sheep supply chain.

The report analyzes the state of the art of the literature on the environmental impact of the sheep supply chain, relatively to global warming. LCA studies on sheep productions (meat, wool, milk and cheese, ecosystem services) and on post-farm emissions were reviewed and discussed focusing their methodological approach and main outcomes. Studies focusing the most important biological and technical option for the reduction of methane emissions, nitrogen excreta and variation of soil carbon stock were also reviewed and discussed. The report allowed to deduce important information for the planning of emission mitigation strategies to be applied in dairy sheep sector at territorial level in the European sheep farming systems.
