Approximately 21% to 37% of total greenhouse gas emissions (GHGe) are attributable to the food system. Primary sources of food system–related GHGe include land clearing and deforestation, which release carbon dioxide (CO2) and nitrous oxide (N2O); production and use of synthetic fertilizers and other agrochemical inputs, which emit CO2, N2O, and methane (CH4); and enteric fermentation of ruminant livestock production (cows, sheep, and goats), which is the leading source of GHGe (CH4). Left unchecked, global food system emissions could prevent us from achieving the 1.5°C and 2°C climate change targets set by the Paris Climate Accord.
