Abstract. Fossil-fuel based energy use in agriculture leads to CO₂ and non-CO₂ emissions. We focus on emissions generated within the farm gate for crop and livestock production and from fisheries, providing information relative to the period 1970–2019 for both energy use and the associated greenhouse gas (GHG) emissions. Country-level information is generated from UNSD and IEA data on energy in agriculture, forestry and fishing, relative to use of: gas/diesel oil, motor gasoline, liquefied petroleum gas (LPG), natural gas, fuel oil and coal. Electricity used within the farm gate is also quantified, while recognizing that the associated emissions are generated elsewhere. We find that in 2019, annual emissions from energy use in agriculture were about 523 million tonnes (Mt CO_2eq yr⁻¹), and up to 1,029 Mt CO_2eq yr⁻¹ when including electricity. They increased 7 % since 1990. The largest emission increases from on-farm fuel combustion were from LPG (32 %), whereas significant decreases were observed for coal (−55 %), natural gas (−50 %), motor gasoline (−42 %) and fuel oil (−37 %). Conversely, use of electricity and the associated indirect emissions increased three-fold over the 1990–2019 period, thus becoming the largest emission source from energy use in agriculture since 2005. Overall the global trends were a result of counterbalancing effects: marked decreases in developed countries in 2019 compared to 1990 (−273 Mt CO₂eq yr⁻¹) were masked by slightly larger increases in developing and emerging economies (+339 Mt CO₂ eq yr⁻¹). The information used in this work is available as open data at: https://zenodo.org/record/5153241 (Tubiello and Pan, 2021). The relevant FAOSTAT (FAO, 2021) emissions database is maintained and updated annually by FAO.
