Organic livestock production and products on a global level... 

According to the Food and Agriculture Organization of the United Nations (FAO) report entitled Livestock s Long Shadow [11], livestock production is achieved at a substantial environmental cost. On a worldwide basis, it contributes 18 % of global greenhouse gas (GHG) emissions. GHG emissions from animal production include CH4 directly emitted from domestic animals or livestock manures, and N2O emitted from land applied manures and grazed lands [12].
