Green Web Foundation

Overview

The Green Web Foundation is an independent non-profit that keeps an open dataset of hosting providers verified to run on green energy, plus free tools built on it. Green Web Check answers whether a given website is hosted by a verified green provider, the Green Web Dataset is downloadable and available through an API, and hosting companies can apply to be verified for free through a provider portal, with the evidence for each claim published. The organisation also runs training and services on digital sustainability, and writes CO2.js, an open source library for estimating the carbon of a site or application. Tools are published under CC BY-SA 4.0 and free to use, with donations funding the dataset's upkeep, and the foundation is based in Amsterdam and Berlin.

Editorial verdict

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.
