Recent studies estimate that the food system contributes about one-third of global greenhouse gas emissions. For perspective, this represents more global greenhouse gas emissions than from the combustion of any individual fossil fuel, including coal. The figures are substantial even at a country level. In the United States, for example, food system emissions constitute about 25 percent of total national global greenhouse gas emissions. In Indonesia, the fourth most populous country in the world, the food system generates over 70 percent of total emissions. In China, the share of global greenhouse gas emissions attributable to its food system is smaller (less than 20 percent), but these emissions are larger in absolute terms than for any other country and constitute nearly 5 percent of global emissions.
