The FAOSTAT domain Emissions from Pre- and Post-Agricultural Production provides estimates of greenhouse gas (GHG) emissions and related activity data associated with pre- and post-production stages of agrifood systems. The domain includes methane (CH4), nitrous oxide (N2O), carbon dioxide (CO2), fluorinated gases (F-gases) and their aggregates expressed in carbon dioxide equivalent (CO2eq). Estimates are computed following Tier 1 methods of the IPCC Guidelines for National Greenhouse Gas Inventories (IPCC, 1996; 1997; 2000; 2002; 2006; 2014) and are disseminated annually.
