UN's FAO report from 2015 states that livestock-related agri-food systems account for 12% of global greenhouse gas emissions, with emissions expected to nearly double by 2050 if no changes are made. Beef production is responsible for 62% of animal production emissions, with methane accounting for over half of total global emissions. To reduce emissions, the FAO recommends increasing productivity, changing animal diets, promoting sustainable agriculture, selecting genetic traits, and reducing waste.
