WebFor livestock production systems, nitrous oxide, methane and carbon dioxide emissions are losses of nitrogen, energy and organic matter that undermine efficiency and productivity. Possible interventions to reduce emissions are therefore to a large extent based on technologies and practices that improve production efficiency at animal and herd levels. WebThe livestock sector is a significant contributor to global human-induced GHG emissions. Livestock supply chains emitted an estimated total of 8.1 gigatonnes CO 2-eq in 2010 (using 298 and 34 as global warming potential for N 2 O and CH 4 respectively). Methane (CH 4) accounts for about 50 percent of the total.Nitrous oxide (N 2 O) and carbon …
