Beef production accounted for 34 percent of the 21.4 billion metric tons of carbon dioxide equivalent (GtCO₂e) emitted by the global food system in 2020. Milk and rice production followed, with each value chain contributing 11 percent of total emissions. Combined, livestock production (including milk) represented roughly 60 percent of global food system emissions.
Almost three-quarters of food system emissions come from agriculture and land use activities, with the remaining shares coming from upstream and downstream services such as transportation, food processing, and packaging.
