What is not publishedthe gaps we looked for and did not find

This record entered the index from Girls Who Eat's non-toxic travel coverage, which states its reviews draw on their own criteria plus information properties supplied or published. Claims are recorded at the tier a third-party report earns. Pathways without a row have not been researched yet and stay out of the denominator. Girls Who Eat also reports Green Key certification and 100 percent renewable electricity; Green Key enters standards only from the certifier's own registry, so it waits there.

Other standards held

Useful context. A held standard does not move a pathway score on its own. It moves a score only through the evidence that standard publishes.

Not published is not unsafehow to read these scores, and what this index does not promise

A low score means a property has not published information. It does not mean the property is unsafe, unhealthy or poorly run.

These scores measure disclosure. These scores describe disclosure, not property quality. This index has no commercial relationship with the properties listed unless a badge on the listing says otherwise.

Conditions change, and we will not always know. Every record is a snapshot of what a property had published when we read it, and that date is on the page. Conditions change: a property can refit, change suppliers or replace a system at any time, and nothing requires it to tell us. We re-read records and ask properties directly for updates, but there will always be a gap between what is true today and what was published when we looked. Use this as a frame of reference for what to ask, not as a substitute for asking. Take your own questions to the property before you book, and tell us if you find something we have wrong.

We report what properties publish. We do not inspect, certify or vouch for any property on this index unless a listing says we assessed it on site, and we accept no responsibility for decisions made or outcomes experienced on the basis of what you read here.
