Emission Factor Database
Definition
Emission Factor Database (EFDB). The EFDB is a continuously revised web-based information exchange forum for emissions factors and other parameters relevant for the estimation of emissions or removals of GHGs at national level. [1]
Objective
The overall objective of the EFDB is to be an always up-to-date companion for the IPCC Guidelines for National Greenhouse Gas Inventory that is seen as a worldwide resource for greenhouse gas inventory developers. The EFDB targets a variety of users, in particular the inventory compilers of the Parties to the UNFCCC, with current and well-documented emission factors and other parameters, as well as to establish a communication platform for distributing and commenting on new research and measurement data.
The platform aims to provide an efficient means for experts and researchers to disseminate new emission factors or other parameters in a timely manner to a worldwide audience of potential end users. The EFDB is meant to be a recognised data repository where users can find emission factors and other parameters with background documentation or technical references.
EFDB Structure
The database structure is in the form of a long database table (~17K entries, one per emissions factor). The data attributes can be grouped in the following categories:
- Identification and Classification of an Emissions Factor: (ID, Gas / Fuel, IPCC Category, Description)
- Applicable Practices and Conditions: (Regional or Technology Conditions and Details)
- Quantitative Data: (The value, range, units and uncertainty)
- Reference Data: (Data sources, references, links etc)
- Other: Any other attribute not fitting in the above
