The Green Web Foundation
Depends on your product. DR 82 and a badge with real credibility, but only for hosting providers who can evidence renewable energy — everyone else is ineligible.

Who actually reads it
Buyers with a sustainability requirement, plus the developers and agencies who check a host against the Green Web dataset programmatically. Site traffic is small, but the dataset itself is queried by other tools, which extends the reach well past the 0.02M figure.
What a strong listing looks like
Actual evidence — renewable energy certificates, supplier documentation — because verification is the entire product. There is no way to talk your way onto this list, which is exactly why the badge is worth having.
