Intergovernmental Panel on Climate Change (IPCC)

The IPCC's Task Force on National Greenhouse Gas Inventories (TFI) develops methodological guidelines and good practice guidance for the preparation of national greenhouse gas (GHG) inventories for use by the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol. These emission estimation methods are, for fuel combustion related emissions, based on fuel consumption data and national energy balances.

The TFI also maintains the Emission Factor Database Project. This is the development of a database of emission factors and underlying information to make available a wide range of information on parameters that could be used to develop national inventories. The aim is to provide a resource of potential emission factors and other parameters that could be used to improve the accuracy of national emission estimates.

The main target users are national inventory compilers, but the information should also be useful to project developers, scientists and the wider public.

Data on carbon contents and emission factors can be found both in the EFDB and our publications.
