What is not publishedthe gaps we looked for and did not find
Two pathways return nothing. On EMF Harmony no network topology, cabling type, access point or smart meter placement, shielding or field reading is published; every villa page lists high speed WiFi, which describes coverage and is not a disclosure either way, and the Digital Detox Journey listed under Wellbeing is a behavioural programme rather than an engineered specification. On Sound and Sensory Ecology no background noise level, acoustic separation figure or plant noise figure is published; the salt room sound therapy on the Wellbeing page is a treatment and the Bose surround sound system listed in the villas is an amenity, and neither measures the room. On Water Integrity the only located statement about the guest's water is a booking platform note that it comes from underground wells: no treatment train, filtration specification, laboratory panel or pool sanitation method is published, and the greywater reuse described there is disposal rather than what the guest drinks. The Song Saa Foundation's marine protected area, coral nursery, mangrove and seagrass monitoring, village rainwater harvesting and distributed water filters describe an ecosystem and neighbouring communities rather than the accommodation, so they are recorded and not scored, as are the resort's solar panels, recycling centre and waste programmes, which are energy and waste rather than guest biology. Aesop toiletries are named in a booking platform listing; bath amenities sit outside what Materials and Textiles covers, and no mattress composition, linen fibre content, paint, adhesive or laundry chemistry is published. The villa, dining and adventure pages read for this record describe no fireplace, wood fired oven or other combustion source inside a guest villa. One source could not be read: Fluidra, a commercial pool systems manufacturer, publishes a customer reference page for this property, indexed as covering its pools and lighting. It returned nothing by any route tried, so its contents are unassessed rather than absent, and the denials above are limited to what could be reached.
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.
- Certified B Corporation Awarded by B Lab. Source
Regional context2 public figures about the area, none of which scores
Public data about the surrounding area. None of it contributes to the score, because a property cannot be marked down for the conditions outside it.
- Safely managed drinking water, Cambodia: The World Health Organization reports 30 per cent of the population nationally, 57 per cent in urban areas, 20 per cent in rural areas using a safely managed drinking water service. This describes the country, not this property, and says nothing about what reaches a guest room here. It is recorded because it is the background against which a property's own treatment is worth publishing. Source
- Ambient PM2.5 and PM10 near Koh Rong Archipelago, Cambodia: Modelled ambient air over this location averaged 8.4 micrograms per cubic metre of PM2.5 and 15.1 of PM10 across the 720 hours to 2026-08-17, peaking at 15.5 PM2.5. The World Health Organization annual guideline for PM2.5 is 5. This is the outdoor air over the area, modelled rather than measured on site, and it is not a reading of the air inside any room. Source
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.
