GHG Protocol Disclaimer

This database is listed as an informational resource to assist users in collecting data for product life cycle and corporate value chain (Scope 3) GHG inventories.

Inclusion in this catalogue does not constitute an endorsement, quality assessment, or recommendation by the GHG Protocol. The catalogue is not exhaustive.

Some of the data in these sources may not be consistent with certain GHG Protocol standards. Before using a database, the user should review its documentation 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. Data should also be evaluated using the data quality indicators described in the Corporate Value Chain (Scope 3) Accounting and Reporting Standard (chapter 7) and the Product Life Cycle Accounting and Reporting Standard (chapter 8). Users should select the highest-quality data available in the context of business objectives and the principles of relevance, completeness, consistency, transparency, and accuracy. 

The databases included meet the following criteria: 

1. It can be used directly by inventory developers. Databases that require purchasing consulting services or proprietary software solely to access the data are not listed.
2. It has a corresponding website on which users can review source documentation and additional information.
3. It is currently maintained or, if not actively updated, remains accessible and documented at a stable URL.
4. It is offered on terms that allow inventory developers to use the data for product life cycle or Scope 3 inventory purposes (free, paid license, or open are all acceptable; absence of any usable access is not). 
5. Where a database is accessible only on a paid or licensed basis, sufficient public documentation must be available for users to assess applicability before purchasing. At minimum, this requires a publicly accessible methodology description, geographic and sector coverage summary, and pricing or access information (including how to request access). Databases for which this information is not publicly available are not listed.
