green steel

The green steel tag on WindowsForum.com collects discussion of lower-emission steel production and how technology companies account for it. A recent thread examines Google's agreement with Swedish steelmaker Stegra, clarifying that Google is buying environmental attribute certificates tied to up to 91,000 metric tons of first-year output rather than taking physical delivery of the metal. The discussion touches on Stegra's hydrogen-based facility in Boden, Sweden, the book-and-claim model, and how lower-carbon attributes can be claimed separately from the steel actually used in data-center construction.
