MetricMicrofibre pollution from textile production washing

Microfibre release from synthetic textile washing during production

Measurement answer

What this metric measures

Reports production washing activity for synthetic textiles and a standardized-test measure of microfibre-related mass loss.

Specification

Result format
Structured table
Unit
Structured table — see field-level units
Reporting basis
Organization's reporting period; the extracted source text specifies production activity but not a reporting-period duration.
Aggregation
Total weight of synthetic textiles washed and total wash cycles during production, together with the average mass loss per kilogram of original sample weight from the standardized laundering test.

Value structure

Dimensions and units

Unit
Structured table — see field-level units
Reporting basis
Organization's reporting period; the extracted source text specifies production activity but not a reporting-period duration.

Unit meaning: Each field uses its stated unit and retains the applicable sector, reporting boundary, period and method.

Table fields and units

  • measurement field
  • measurement basis
  • reported value
  • unit
  • test method or production-data method
  • coverage notes

Published dimensions

  • metric field: synthetic-textile weight washed, wash cycles, or mass loss
  • measurement basis: production washing activity or standardized domestic-laundering test
  • original sample weight denominator for mass loss

Structured Disclosure

Disclosure form

No single formula

Report the source-defined result with its stated fields and method disclosures. The source specifies a coherent three-field reporting family rather than a single common-unit result. The fields must remain together because production washing totals and the standardized domestic-laundering mass-loss result have different units, denominators, and measurement bases.

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.

Interpretation boundaries

Method disclosures required

Source-edition basis: TNFD sector guidance, Final English sector guidance collection through August 2026 (17 documents).

  • Standardized test method, version, laboratory or testing protocol, and how it simulates domestic laundering.
  • Definition of synthetic textiles and the textile products or materials included.
  • Production sites and outsourced processing included in the washing-activity boundary.
  • Method for counting wash cycles during production.
  • Original sample weight basis and calculation method for average mass loss.

Record-specific limitations

  • The extracted text does not identify the standardized test method by name or edition.
  • The source does not specify textile categories, facility coverage, geographic coverage, or whether production washing includes outsourced processing.
  • Production activity totals and standardized-test mass-loss results are distinct measurement bases and should not be combined into one scalar value.

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.
