Editor's take on IBM Cloud Carbon Calculator
Fits IBM Cloud customers that need emissions attributed to accounts, regions, locations and services, with both market-based and location-based figures so the accounting choice is explicit rather than baked into one number. Export and an API route data into reporting pipelines, and access follows billing roles. The trade-off is scope and commercial clarity: it covers IBM Cloud only, no price is published for the calculator, and the documentation does not describe audit or factor-level detail. Multicloud estates need a second source, and buyers should confirm what the contract includes.

Fits teams that need one consistent way to read provider energy and carbon metadata across AWS, Azure and Google Cloud, or that are planning carbon-aware scheduling on real-time signals. It supplies a standard and a normalised dataset rather than a product, and the standard itself notes that providers release carbon data monthly with delays of several months, so the real-time aim depends on provider adoption. No licence file was found in the repository, which matters for redistribution. Teams wanting a turnkey dashboard should pair it with implementation tooling.
