Food system GHG emissions worldwide, by segment
It is estimated that the global food system produces the equivalent of 17.9 billion metric tons of carbon dioxide emissions (tCO2e). Of this total, land use and agricultural production contribute 5.7 billion tCO2e and 7.1 billion tCO2e, respectively. The supply chain - which includes processing, transport, packaging, and retail - is estimated to account for 17 percent of food system emissions.
