A summary of each source - including data formats, accessibility, content, and transparency information - is available by clicking on the database link. The list is not exhaustive and the inclusion of a database in this list does not constitute an endorsement by the GHG Protocol.
Some of the data in these sources may not be consistent with certain GHG Protocol standards. Before using a database, its documentation should be reviewed for transparency, completeness, and applicability to the GHG inventory for which the data is being collected. For example, a database may contain combustion-only emission factors that are not applicable to product life cycle GHG inventories.
