Share of apparel supplier sites meeting wastewater requirements
Measurement answer
What this metric measures
Percentage of in-scope apparel supplier facilities meeting a declared wastewater compliance basis, calculated separately for direct-tier and upstream-tier facility populations.

Reporting boundary
Facilities are evaluated against the declared permit, contractual requirement or eligible wastewater-standard basis for the reporting period.

- Unit
- Compliant supplier facilities (%)
- Reporting basis

Formula
P_t = (C_t ÷ F_t) × 100For each supplier tier and compliance basis, divide compliant in-scope wastewater-discharging facilities by all compatible in-scope facilities in that tier. The source supplies no zero-denominator or rounding rule.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
C_t | compliant facilities in tier t | In-scope wastewater-discharging supplier facilities in tier t that meet the declared permit, agreement, or wastewater-standard basis. | supplier facilities |
F_t | total in-scope facilities in tier t | All compatible in-scope wastewater-discharging supplier facilities in the same tier, period, and compliance-basis population. | supplier facilities |
Verified sources
Evidence and status sources
Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Record-specific limitations
- Do not count suppliers when the unit is supplier facilities.
- Keep tier denominators separate.
- Do not mix permit or contractual compliance with voluntary-standard conformance without a basis dimension.
- Missing or estimated upstream-facility coverage is not zero or full compliance.
- The accompanying risk narrative is context and must not be counted as another percentage.
- Tier results are separate and cannot be averaged without their facility counts.
- A zero denominator has no source-defined numeric result.
Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.
Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
