The GHG Protocol Scope 3 Evaluator was decommissioned on August 30, 2023.

When developing this tool a decade ago, it was our intention to accelerate the adoption of the Scope 3 Standard by offering a simple, free entry-point for companies to make a rough approximation of its emissions across all 15 Scope 3 categories.

This has been a great success and Scope 3 is now a routine part of corporate GHG emission tracking, reporting and targets. Although this tool has gradually become obsolete, it has served its purpose and allowed for this space to mature to a point where there are many other tools and support providers in the community.

We’ve provided answers below to what we expect are the most frequent questions our users may have, as we are unable to provide any personalized support. Note that there is also a Frequently Asked Questions page available from the header in the tool that contains additional information about the tool.

Why is the tool being discontinued?

The Scope 3 Evaluator was designed around 10 years ago and is built on what is now outdated technology. Parts of the tool utilize Javascript, which is a programming language that is increasingly unsupported by modern web browsers and causes user interface errors.

Are there other tools I can use instead?

GHG Protocol’s Scope 3 website includes links to our Scope 3 calculation guidance, a list of third-party life cycle databases, GHG Protocol calculation tools, and our Scope 3 online course. There are also external software tools available to support with Scope 3 accounting and reporting. GHG Protocol does not endorse external tools but a web search for tools able to support Scope 3 emissions estimation should help you identify options.
