Throne Standard for stays 2.2. Accommodation Eco Score weights: Nature, biodiversity and regeneration 30%, Energy and climate 15%, Water 10%, Waste and plastic 10%, Food, farming and sourcing 15%, Buildings, heritage reuse and land use 15%, Measurement, transparency and certification 5%. Each pillar earns its weight times its level divided by four. The score is 1 plus 4 times the evidenced performance, shown to one decimal, so 0% is 1.0 and 100% is 5.0. A pillar the stay does not disclose, after we read its own pages, counts as 0 and is shown as Not disclosed, with every page we read linked, because silence is an answer too. Every finding quotes its source word for word. Below 85% coverage, below 70% performance, or with less than half the weight at level 2 or above, the score is held under the next whole number (3.4 or 2.4). A 5.0 band needs 90% coverage and performance, level 4 evidence on half the weight and the key pillar at level 3 or above. Green flags are pillars at level 3 or 4. Every level can be earned from public, dated evidence; no score requires a visit. Evidence must be rechecked within two years. Guest travel is not scored; everyone gets there how they can.
