The tools listed below were developed in close collaboration with GHG Protocol and were reviewed at the time of publishing to be in conformance with the current GHG Protocol standards and guidance.
The Built on GHG Protocol review service will be closed until further notice as we work on our long-term strategy. Until our new services are defined, we will continue to host previously approved tools. We will be updating this page over the course of 2024.
Please note if the tool is dated prior to the date of the conforming standard or guidance we cannot confirm it is in compliance with the most updated version.
