| In accordance with Articles 4 and 12 of
the Convention, and the relevant decisions of the Conference of the
Parties, Parties to the Convention submit national greenhouse gas
inventories to the Climate Change secretariat. These inventory data
are provided in the national communications under the Convention by
Annex I and non-Annex I Parties, and in addition Annex I Parties
submit annual national greenhouse gas inventories.
The GHG data tables contain estimates for:
Main greenhouse gases
CO2 - Carbon dioxide
CH4 - Methane
N2O - Nitrous oxide
PFCs - Perfluorocarbons
HFCs - Hydrofluorocarbons
SF6 - Sulphur hexafluoride
The data contain only the most recently submitted information,
covering the period from 1990 to 2003, to the extent the data have
been provided. In some cases, the most recent information for a
period of years (e.g. 1990-2003) is based on different submissions,
as information submitted from year to year does not necessarily
include data for years previously submitted. Thus the data may not
necessarily be consistent or comparable among years for a given
Party. Please see
"Information on data sources" for an indication of the sources
of data.
The data are reproduced here as reported, with the exception of
rounding during data processing and corrections of typographical or
calculation errors or omissions, therefore totals and sub-totals may
differ from the sum of the individual components.
Predefined
queries are available while the searchable GHG database is
currently under going redevelopment and is unavailable.
Emission source categories
Emission estimates are presented in accordance with the source
categories (definitions)
of the Intergovernmental Panel on Climate Change Guidelines for
National Greenhouse Gas Inventories (1996).
It should also be noted that the category "National Total" does
not include emissions resulting from fuel sold to ships or aircraft
engaged in international transport (international bunker fuel
emissions).
“-- “ in the tables indicate emissions whose values are zero or
not reported.
Global Warming Potentials
The Global Warming Potentials (GWP)
used for presentation of CH4 and N2O in terms
of CO2 equivalent are 21 and 310, respectively. For HFCs,
PFCs, and SF6 the GWP for a 100 year time horizon have
also been used. (source of GWP: Climate Change 1995: The Science of
Climate Change, table 4, p. 22, Intergovernmental Panel on Climate
Change, 1996).
