Pidan vs Tansk: how to read this comparison
Both brands are scored on the same 0–100 methodology, so the numbers are directly comparable: current third-party certifications, material and ingredient sourcing, labour standards, packaging and end-of-life, and public conduct including recalls and greenwashing findings.
A gap of a few points is usually noise from data completeness rather than a real quality difference. A gap of fifteen points or more normally reflects something concrete — a missing audit, an unpublished supply chain, or an unresolved controversy — and the brand pages explain which.
Score is not the same as fit. Compare at product level for the category you actually need: a brand can be strong in textiles and weak in personal care, and the averages hide that.
What each criterion covers
| Criterion | What we check | Typical evidence |
|---|---|---|
| Certifications | Current, accredited, in-scope marks | Public register entries |
| Materials | Origin, recycled content, traceability | Composition labels, mill names |
| Labour | Wages, audits, supplier disclosure | Published tier-one lists |
| Packaging | Plastic-free, refill, recyclability | Pack specifications |
| Conduct | Recalls, rulings, controversies | Regulator notices, court findings |

- Look at repairabilityFor durable goods this outweighs almost everything else.
