(little research with a life cycle perspective focused on dairy sheep systems)
SPECIFIC: to analyze the environmental implications of a transition from a semi-intensive (2001) to a semi-extensive (2011) production system IN THE SAME FARM, with a Life Cycle Assessment (LCA) MAIN: to fill the knowledge gap

LCA methodological issues All data were organized into a Life Cycle Inventory (LCI), the process that quantifies energy and raw material requirements, atmospheric and waterborne emissions, solid wastes and other releases for the entire life cycle of a product Enteric methane emissions were quantified using a detailed approach (IPCC Tier 2/3) and considering the total metabolizable energy ingested with the specific animal category diet. Evaluation method: IPCC (2013) which provides estimates on greenhouse gases emitted in the life cycle of products (Carbon Footprint), expressed in kilograms of CO2-equivalents LCA calculation was made using LCA software SimaPro 8.1.1 (PRé Consultants, 2016).

The LCA study highlighted that the transition from a semi-intensive to a semi-extensive production system
