A bar chart illustrating global greenhouse gas emissions from food production. The graphic indicates total global emissions as 52.3 billion tonnes of CO₂-equivalents, with 74% attributed to non-food sources and 26% to food sources. Key categories of food emissions are displayed: - **Livestock and fisheries** - **Crop production** - **Crops for human food** - Additional supply chain components include retail (3%), packaging (5%), transport (6%), and food processing (4%). Wild fisheries account for 1%. The data source is attributed to Joseph Poore and Thomas Nemecek (2018), published in Science, and licensed under CC-BY by the author Hannah Ritchie (November 2022).
