The FAOSTAT domain on Emissions from Energy use in agriculture contains data on energy used in agriculture (including forestry, aquaculture and fisheries), for instance to operate machinery, irrigate, heat stables, operate aquaculture ponds and fishing vessels, and related greenhouse gas (GHG) emissions. It also includes on-farm use of, and related GHG emissions from, electricity and heat generated off-farm. Data are available by country and regional groups with global coverage and are updated annually.
