The GHG Protocol creates standards and tools that are applicable to any organization, company, and sector. In response to user needs, the GHG Protocol also develops calculation tools that build upon the more general standards. However, other groups and organizations are also developing their own tools to support GHG Protocol standards.
The tools below were developed in close collaboration with the GHG Protocol, and have been reviewed to ensure that they are in conformance with the GHG Protocol standards. They have earned the "Built on GHG Protocol" mark, which recognizes accounting resources that have been developed in conformance with a GHG Protocol standard.
