Evidence before a verdict

The Throne Standard

What each score measures, how its evidence is counted, and what it cannot tell you.

Textile and catalogue Standard 1.3.1 · effective 2026-10-03. Accommodation environmental model 2.1.0. These are separate assessments.

Textiles: an evidence rate, not a universal sustainability score

The ordinary textile score measures the share of the eligible catalogue supported by complete plant-only composition evidence. It does not measure the percentage of plant fibre by physical weight across a brand, lifecycle emissions, animal welfare, organic status, fair wages, safety or overall ethics.

Verified plant products ÷ eligible textile catalogue products × 100

A complete, attributable composition is required for pure-plant product credit. Partial wording, unknown remainders, conflicting evidence and impossible totals cannot earn complete plant credit. Single-component percentages must total 100% within the Standard tolerance. Named components are assessed separately; their percentages must not be added into one impossible garment total.

Material categories describe this method

Cotton, linen and hemp are plant fibres. Wool, silk and cashmere are animal-derived natural fibres; they do not meet this method’s plant-only preference. Polyester, nylon and elastane are synthetic. Viscose, modal and lyocell are regenerated or semi-synthetic fibres in this Standard; their plant feedstock does not make them eligible plant-fibre credit here. These categories are disclosed scoring choices, not claims that every excluded fibre is environmentally worse in every application.

The animal-material floor is a separate rule: if animal materials account for at least 95% of the classified nonplant share, the minimum ordinary textile score is 2/5. Where applied, the report must disclose that adjustment. It does not establish vegan status, welfare, certification or overall ethics.

Readable, undisclosed and unread are different

Successfully read but undisclosed products remain in the eligible denominator with zero verified-evidence credit. Products outside the textile scope are excluded with an explicit reason. Blocked, timed-out, unread and conflicting records remain technical or evidence gaps; they are not relabelled undisclosed or synthetic. A current authoritative catalogue result requires trusted complete enumeration, reconciled identities, no reader failures and no unresolved evidence errors.

Subset results and samples cannot be presented as a verified whole-brand census. The Standard permits documented fallback analysis when a census is impossible, using random or appropriate stratified selection and a stated confidence interval; taking the first products is not a valid sample. Its 20-product subset guard does not require a genuinely smaller complete catalogue to contain 20 products.

Swimwear has a separate rule

Eligible swim garments use verified natural-fibre share, including plant and animal fibres. Full quantified composition is required. Regenerated and synthetic fibres do not count toward this natural-fibre metric; recycled synthetics may be described separately. Cover-ups, dresses, towels and accessories are N/A as swimwear merely because the store sells swimsuits.

Swimwear natural-fibre score bands
ScoreUnrounded evidence rateMeaning

Illustrative example: a complete swimsuit composition of 80% nylon and 20% elastane has 0% natural fibre under this rule and a 1/5 product result. A verified 75% natural-fibre eligible garment falls in 4/5. Neither result alone establishes that the product is sustainable overall. Where the permitted equal-component fallback is used because component weights are unpublished, the estimated basis stays visible. A catalogue average requires verified eligible swim garments and its stated denominator.

Read a textile report, line by line

This is a teaching example, not a finding about a real brand. One market, one locale, 100 eligible textile products; every product page was successfully read.

Total eligible textiles10080

80 verified plant products ÷ 100 eligible products × 100 = 80% → 3/5

The disclosed-only plant rate is 80 ÷ 95 = 84.21%; it is a different metric and does not replace the full-catalogue rate. The five undisclosed products are unknown, not synthetic. If three pages had timed out instead, the record would have a technical gap and would not qualify as an authoritative census.

A real report must also identify the product URL, date, source wording, standard and reader versions, catalogue identities, exclusions, coverage, conflicts, market and locale. A brand-level result never substitutes for an unmatched SKU.

Accommodation Eco Score: weighted environmental evidence

We calculate environmental performance and evidence coverage separately. Having a filled database field, a solar panel or attractive surroundings does not by itself earn a high score. Ownership and community details remain separate from this environmental assessment.

Accommodation model weights
PillarShare of totalContribution rule
Nature, biodiversity and regeneration30%Weight × evidenced level ÷ 4
Energy and climate15%Weight × evidenced level ÷ 4
Water10%Weight × evidenced level ÷ 4
Waste and plastic10%Weight × evidenced level ÷ 4
Food, farming and sourcing10%Weight × evidenced level ÷ 4
Buildings, heritage reuse and land use15%Weight × evidenced level ÷ 4
Transport and operational footprint5%Weight × evidenced level ÷ 4
Measurement, transparency and certification5%Weight × evidenced level ÷ 4

Each pillar needs an attributable finding, a dated public source and a supported level: 0 documented contrary evidence or absence; 1 a claim; 2 a specific implemented system; 3 several evidenced systems; 4 quantified outcomes or independently verified exceptional implementation. A business’s stated practice is identified as its report, not silently promoted to independent verification. Evidence more than two years old needs a fresh check.

Coverage = sum of evidenced weights
Performance = earned weighted points ÷ evidenced weights × 100

The initial band is round(1 + 4 × earned points ÷ coverage), bounded to 1–5, then constrained by evidence safeguards. At least 70% weighted coverage is needed for any score. Below 85% coverage the result is capped at 3/5. If less than half the total weight supports implemented systems, it is capped at 2/5. A 4/5 needs at least 70% evidenced performance. A 5/5 additionally needs at least 90% coverage and performance, level-4 evidence across at least half the total weight, and nature evidence at level 3 or higher.

Illustrative example: nature level 3 earns 22.5 of 30 points; heritage/buildings level 3 earns 11.25 of 15; energy level 2 earns 7.5 of 15. If these are the only evidenced pillars, coverage is 60%, so the score is withheld, even though performance on those pillars is 68.75%. Missing pillars are unknown, not proof of harmful practice.

Other categories are not textile scores

Beauty uses the proportion of fully assessed ingredient declarations meeting HTT’s stated INCI purity preference; it is not an ingredient concentration, medical safety test or universal definition of “natural.” A partial beauty result is calculated from the assessed declarations only and is labelled with assessed and unresolved product counts. It does not describe the unresolved products or prove whole-catalogue coverage. A 5/5 partial result means every assessed declaration passes; it is not a verified whole-brand 5/5. A current authoritative beauty catalogue score requires complete declarations and no unresolved ingredients. Animal-derived ingredients require product-specific evidence before a non-vegan finding.

Electronics environmental performance, electronics ethics, food ingredients and cocoa supply-chain findings use their own relevant evidence and scope. A textile 5/5 must never be attached to these categories. Where a current supported category assessment is missing, the page states that it is unavailable. A preference for raw or plant ingredients does not substantiate toxicity, health benefits, zero exploitation or a complete lifecycle claim.

Every claim needs the right proof

A composition score does not establish GOTS certification or vegan status. A brand-name search absent from a register establishes only the recorded search outcome, with its exact query, result and date. Manufacturer certification, certificate holder, validity, product scope and transaction documentation must be considered separately; absence of a brand-name match does not prove its products are uncertified.

Non-vegan findings require the exact SKU, attributable ingredient or material wording, source and date. An unavailable declaration is an evidence gap, not proof of animal content. Boycott tools attribute the listed name and campaign scope to their source; absence from checked sources is not clearance.

Prices show the observed currency, storefront market, SKU or variant scope and check date. Exact SKU prices require a matching identifier; a product price range is not a unit price for every variant. No currency or affiliate programme is invented. Source changes are dated; Wayback links do not guarantee an archived capture exists.

Version history

1.3.1 · 2026-10-03

  • Removed the swimwear-specific scoring exception. Swimwear now uses the same textile composition plant-share scoring as clothing and bedding.
  • Legacy swimwear result fields remain compatibility-clearing fields only and no longer calculate or alter a score.

1.3.0 · 2026-10-03

  • Separate measured composition quality from evidence coverage; missing evidence no longer receives a zero composition value.
  • Aggregate full declared plant percentages across assessed products, including blends.
  • Scope partial scores to assessed products; retain catalogue bounds and prohibit inference from non-random subsets.
  • Preserve raw source inputs and prefer compatible complete declarations over shortened material summaries.
  • Remove inferred equal component weights from numerical composition scoring.

1.2.0 · 2026-09-30

  • Partial material evidence never earns complete pure-plant product credit. Unknown remainder stays explicit.
  • Impossible totals in a single composition are evidence errors and block automatic score publication. Separate complete named components are not summed as one garment; estimates remain identified.
  • Route every SKU independently and keep distinct department and swimwear results. Unknown departments return an unresolved result.
  • Automatic score publication requires trusted complete catalogue enumeration, reconciled product identities and no unresolved evidence errors.
  • Capture stated offers in the declared default currency, then a real USD offer; never invent a currency or exchange rate.
  • Beauty catalogue scores use the shared evidence-rate bands; 5/5 requires every assessed product to pass and no unresolved declarations. Score thresholds use unrounded rates.
