GHG data from UNFCCC

In accordance with Articles 4 and 12 of the Climate Change Convention, and the relevant decisions of the Conference of the Parties, countries that are Parties to the Convention submit national greenhouse gas (GHG) inventories to the Climate Change secretariat. These submissions are made in accordance with the reporting requirements adopted under the Convention, such as The UNFCCC Reporting Guidelines on Annex I Inventories (document FCCC/SBSTA/2004/8) for Annex I Parties and Guidelines for the preparation of national communications for non-Annex I Parites (decision 17/CP.8). The inventory data are provided in the annual GHG inventory submissions by Annex I Parties and in the national communications under the Convention by non-Annex I Parties.

The GHG data reported by Parties contain estimates for direct greenhouse gases, such as:

CO2 - Carbon dioxide
CH4 - Methane
N2O - Nitrous oxide
PFCs - Perfluorocarbons
HFCs - Hydrofluorocarbons
SF6 - Sulphur hexafluoride

as well as for the indrect greenhouse gases such as SO2, NOx, CO and NMVOC.

The sources and availability of data are described in detail under "Information on data sources". The major data definitions can be found under "Definitions"; for more information on definitions and methodologies, relevant methodological publications of the Intergovernmental Panel on Climate Change (IPCC) should be consulted (see
