The FAOSTAT domain Fires consists of estimates of methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) from biomass burning in a range of vegetation types and from fires in organic soils. Data are computed geospatially using Tier 1 default factors of the 2006 IPCC Guidelines for National greenhouse gas (GHG) Inventories and of the Supplement on Wetlands (IPCC, 2006; 2014) for the organic soils component. Estimates are available by country and with global coverage, in complete time series for the period 1990–2019. The database is updated annually.
