Emissions Totals

The FAOSTAT domain Emissions Totals summarizes the greenhouse gas (GHG) emissions generated from agrifood systems and that are disseminated in the FAOSTAT Climate Change Emissions domains. Data are computed following the Tier 1 methods of the Intergovernmental Panel on Climate Change (IPCC) Guidelines for National greenhouse gas (GHG) Inventories(IPCC, 1996; 1997; 2000; 2002; 2006; 2014). Emissions from other economic sectors as defined by the IPCC are also disseminated in the domain for completeness. The domain includes methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) emissions from all the above activities as well as the aggregate fluorinated gases (F-gases) emissions used in industrial processes. Estimates are available by country, with global coverage for the period 1961–2020 with projections for 2030 and 2050 for some categories of emissions or 1990–2020 for others. The database is updated annually

The FAOSTAT domain Emissions Totals disseminates information estimates for the single gases and their aggregates in CO2eq in units of kilotonnes (kt or 10*6 kg). The latter are computed by using the IPCC Fifth Assessment report global warming potentials, AR5 (IPCC, 2014).

Emissions from agrifood systems are those generated within farm gate, those associated with the land use change and the emissions from pre- and post-production food processes. The latter emissions are calculated based on data from the UN Statistical Division (UNSD), the International Energy Agency (IEA) and other third-party as well as by integrating emission information from the PRIMAP-hist dataset v2.4 (Gütschow et al., 2022). Methodologies for these estimates are described in dedicated working papers as follows: I) food transport; II) food systems waste disposal and III) fertilizers manufacturing, food processing, retail, packaging and household consumption. It should be noted that, the world aggregate estimates of food transport also includes international bunkers related to food. Emissions from “International Bunkers” is derived from data on ‘International aviation’ and ‘International navigation/shipping’ of the EDGARv6.0 dataset (JRC/PBL, 2019), covering the period 1990–2018 and extrapolated linearly to 2020 by FAOSTAT Domain Emissions Totals. Emissions for this category are only available for the world aggregate.

PRIMAP data for other IPCC sectors is also disseminated for completeness and in view of computing shares of emissions for the whole economy (these are disseminate separately in the FAOSTAT domain Emissions shares). The IPCC economic sectors are: energy, industrial processes and product use (IPPU), waste and other n.e.c. These data are sourced from the PRIMAP-hist v2.4 dataset (Gütschow et al., 2022).

Emissions Totals jointly disseminates the emissions reported by countries to the United Nations Framework Convention on Climate Change (UNFCCC). Emission data are sourced directly from the UNFCCC data portal as submitted by countries through their most recent GHG National Inventories (NGHGI) or are extracted from Biennial Update Reports (BURs).UNFCCC data are disseminated in FAOSTAT with permission, formalized via a FAO-UNFCCC Memorandum of Understanding. Values for Annex I and non-Annex I groups are computed from the UNFCCC data for the single categories of emissions listed in Table 1 and for IPCC Agriculture aggregate. It should be noted that due to incomplete reporting, significant data gaps characterize the non-Annex I aggregates.
