Smart Net-Zero

Food and Agriculture Organization (FAO) | Source | Report |

This FAO report provides the most comprehensive global inventory of GHG emissions from agrifood systems, covering production, land use change, supply chains, and consumption-related activities from 2001 to 2023. It estimates total agrifood emissions at 16.5 Gt COâ‚‚eq in 2023, representing roughly one-third (about 32%) of global anthropogenic emissions and a 21% increase since 2001. Methane (CH₄) from livestock—particularly enteric fermentation and manure management—remains the largest single emissions source, followed by deforestation, while emissions from pre- and post-production supply chains have grown by 33% since 2001 and now account for around 32% of total agrifood emissions. The report highlights strong regional contrasts, with rapid growth in parts of Asia and Africa alongside stabilization or decline in some high-income regions. By providing country-level time series, it supports evidence-based climate-smart agriculture (CSA) planning and offers a robust data foundation for integrating agrifood mitigation into NDCs, long-term strategies, and national MRV systems.
