Food and Agriculture – Public health benefits of reduction in greenhouse-gas emissions.

80% of agricultural emissions arise from Livestock – methane and nitrous oxide.

Agriculturally-induced change in land use – deforestation, overgrazing, and conversion of pasture to arable land – accounts for a further 6 – 17% of global greenhouse gas emissions. 50% of food-related greenhouse-gas emissions are generated during farming. These include nitrous oxide and methane from livestock, carbon dioxide from deforestation especially; Nitrous oxide comes from pasture land and arable land used to grow feed crops and methane from the gut of ruminant animals such as cattle and sheep. Pork chicken and eggs produce less CO2 and are more efficient at feed conversion.
