Welcome to EFDB!

  • Nature of EFDB: EFDB is meant to be a recognised library, where users can find emission factors and other parameters with background documentation or technical references that can be used for estimating greenhouse gas emissions and removals. The responsibility of using this information appropriately will always remain with the users themselves.
  • Request for data input: Users are encouraged to provide the EFDB with any relevant proposals on emission factors or other related parameters. If you wish to submit your data for the first time, please contact the Technical Support Unit to obtain your login name and password. Acceptance of such proposals will be subject to evaluation by the EFDB Editorial Board using well-defined criteria.
  • Terminology: EFDB is a database on various parameters to be used in calculation of anthropogenic emissions by sources and removals by sinks of greenhouse gases. It covers not only the so-called "emission factors" but also the other relevant parameters. For convenience sake, however, the term "Emission Factor" or its abbreviation "EF" is sometimes used to represent parameters in this database generally.
  • Software requirements: It is highly recommended to use Microsoft Internet Explorer version 5.0 or higher for best performance. Alternatively Netscape Navigator version 6.0 or higher can be used. It is also recommended to have Microsoft Office 97 or higher for generating Word and Excel outputs.
  • EFDB at present contains only the IPCC default data (default data presented in the Revised 1996 IPCC Guidelines for National Greenhouse Gas Inventories and the IPCC Good Practice Guidance and Uncertainty Management in National Greenhouse Gas Inventories). It also contains the data from CORINAIR94, but please note that these data records may be renewed in due course in accordance with the latest version of CORINAIR data set (i.e., data in the Joint EMEP/CORINAIR Atmospheric Emission Inventory Guidebook, Third Edition. Copenhagen: European Environment Agency, 2001). It is highly recommended to consult the website at http://reports.eea.eu.int/EMEPCORINAIR4/en for details on CORINAIR data.
