The number on a cocoa listing is purity: the share of scored products whose ingredient list is readable and has no flagged processing marker. This section is the supply-chain ethics finding. It stays separate and is not a second score.
How the Throne Standard is calculated for cocoa supply chain
Pack: Cocoa 1.0.0 · Standard 2.2 · Engine: Pillar · Status: Evidence. The ethics finding is shown separately from the purity score
Cocoa is a separate supply-chain layer covering traceability to farm, child-labour monitoring and remediation, living-income premiums, deforestation compliance and the certification chain.
Criteria, weights and evidence levels| Criterion | Weight | Level 2 | Level 3 | Level 4 |
|---|
| Traceability to farm | 25 | Country and region of the beans named per product, or the cooperative named. | Beans traced to named cooperatives or farms, with the share of fully traceable volume for a stated year. | Farm-level traceability verified by a third party and current. |
|---|
| Child-labour monitoring and remediation | 25 | A monitoring and remediation system named for the supply base. | Coverage quantified, with cases found and remediated for a stated year. | Independently audited, with published results under two years old. |
|---|
| Living-income premium | 20 | A premium above the market or certification price is stated. | The premium amount and the share of volume covered, for a stated year. | Payments verified by an independent audit or a named open-chain scheme. |
|---|
| Deforestation compliance | 20 | A no-deforestation commitment with a cut-off date. | Farms mapped and checked against forest cover, with the share mapped for a stated year. | Deforestation-free status verified by a third party, or a current due-diligence statement. |
|---|
| Certification chain | 10 | A certification named for the cocoa. | Scope and licence or certificate number published for the products assessed. | Certification verified current with the certifier and scoped to the products assessed. |
|---|
Level 0 is dated contrary evidence, or a source we read that shows the practice is absent. Level 1 is a claim with no supporting evidence. A criterion whose source was not found, not read or blocked is unknown, which is different from 0. A certificate is checked for holder, scope, validity and product coverage; "free from" wording is level 1 until a test report or scoped certificate backs it.
The calculation
V = 25 × S ÷ W, where S = sum of (weight × level) and W = sum of evidenced weights
- Each level earns a quarter of the criterion's credit per step: level 4 is full credit, level 1 a quarter.
- Coverage C = 100 × W ÷ total applicable weight. Below 70% the item is unresolved; below 85% it is capped at 89.99 (3/5).
- If less than half of the total applicable weight is at level 2 or above, the value is capped at 59.99 (2/5), so a page of claims cannot score well.
- Key criterion: child-labour monitoring and remediation. A 5/5 needs it at level 3 or above, otherwise the value is capped at 99.99.
- Exact integer band tests: 5/5 when S = 4W; 4/5 when 5S ≥ 18W; 3/5 when 5S ≥ 12W; 2/5 when 5S ≥ 8W; otherwise 1/5.
Bands (the same in every category)| Value | Band |
|---|
| 100 | 5/5 |
|---|
| 90 to below 100 | 4/5 |
|---|
| 60 to below 90 | 3/5 |
|---|
| 40 to below 60 | 2/5 |
|---|
| 0 to below 40 | 1/5 |
|---|
All arithmetic is exact (fractions, never rounded floating point). Nothing is rounded before the band test, and each band includes its lower bound. Values are shown cut to two decimals, never rounded up, so 89.996 shows as 89.99 and is 3/5.
A worked example, for illustration
No cocoa supply chain item has been scored yet, so these evidence levels are illustrative. Every number below is computed by the scoring engine. The evidence levels for this category are still being written, so no cocoa supply chain can be scored until they are published.
Illustration: a chocolate brand| Criterion | Weight | Evidence level | Weight × level |
|---|
| Traceability to farm | 25 | 3 | 25 × 3 = 75 |
|---|
| Child-labour monitoring and remediation | 25 | 3 | 25 × 3 = 75 |
|---|
| Living-income premium | 20 | 2 | 20 × 2 = 40 |
|---|
| Deforestation compliance | 20 | 3 | 20 × 3 = 60 |
|---|
| Certification chain | 10 | 2 | 10 × 2 = 20 |
|---|
Calculation| Step | Result |
|---|
| Evidenced weight W | 100 |
|---|
| Weighted sum S | 270 |
|---|
| Coverage C = 100 × W ÷ applicable weight | 100 × 100 ÷ 100 = 100.00% |
|---|
| Value V = 25 × S ÷ W | 25 × 270 ÷ 100 = 67.50 |
|---|
| Result | value 67.50, band 3/5 |
|---|
Results
Each brand gets its own result. Documented findings (for example unremediated forced labour, or captive wildlife as a core activity) cap the final band after the calculation, and are always disclosed. Unknown is never a fail.
Evidence we use
Supply-chain disclosures, monitoring reports, premium payments and certification records. Every record keeps its source address, exact locator, capture date and a SHA-256 hash of what we read. Evidence older than two years is re-checked before it supports a high level.
What the listing shows
Purity is the score out of 5. The ethics finding quotes what the brand's own pages say about the supply chain. The public page does not turn that finding into a second number.
