Editor's take on Green Web Foundation
The closest thing to a neutral reference when a vendor says its cloud runs on green energy: the dataset records which providers are verified and publishes the evidence, so a procurement team can check a claim instead of taking it. It is a registry and a set of utilities, not a platform to buy, and the free tier reflects that, which matters for a small team building a supplier shortlist on no budget. Two limits: verification covers the provider's energy sourcing, not the emissions of a buyer's own workload, and a provider outside the dataset is unverified rather than proven dirty. Pair it with a measurement tool rather than reading it as a footprint.

Fits buyers who need generative AI with a European processing story they can put in a procurement file: EU inference is the default route, account data stays in the EU, and token prices are published per endpoint rather than quoted. The API is OpenAI-compatible, so an existing client changes base URL and model id rather than the integration. Model choice is a reseller catalogue of open-source models with published rates, which makes per-workload cost easy to compare, and the US endpoint is documented along with the models it does not serve. Procurement teams should note that the licence is proprietary and that the sustainability and privacy statements are the vendor's own published claims, not third-party certifications recorded in this register.
