Comparative Assessment of Greenhouse Gas Emissions in Pig Farming Using Tier Inventories

Although pig meat accounts for nearly half of total production in Europe, less attention has been focused on the greenhouse gas (GHG) emissions farming. The aim this study was to assess and compare impact livestock GHG during period 2015–2020 major European countries, including Greece, using different computational approaches (Tier 1, Tier 2, Gleam-i software v. 2.0 developed by FAO, Rome, Italy). A semi-extensive farm also used as a small-scale scenario. ranking countries related not affected applied methodology. Spain had highest due higher number farming animals. noted numeric differences estimations can be attributed elaborated equational approach that 2 methodology followed, considering many parameters. Additionally, lower emissions/fewer animal compared average intensive Greek territory. 1 revealed breeding animals produces more emissions, contrary which showed fattening pigs is responsible majority emissions. Therefore, specific categories could targeted (i.e., gilts) specialized manner apart from general strategies improvement).
