MetricSupplier environmental assessment

Suppliers with significant negative environmental impacts where improvements were agreed

Measurement answer

What this metric measures

Source-reported percentage of suppliers identified with significant actual or potential negative environmental impacts where improvements were agreed after assessment, without implying implementation or outcome.

Specification

Result format
Structured table
Unit
Identified environmental-impact suppliers with improvements agreed (%)
Reporting basis
Reporting period or measurement date declared by the source method
Aggregation
Do not sum or arithmetically average reported percentages, rates, ratios, or averages; consolidate only from compatible component observations under a disclosed method.

Reporting boundary

Source-reported percentage only. One supplier with multiple impacts is not counted multiple times in a supplier total unless the source explicitly reports impact-supplier pairs. Impact breakdowns can overlap and are non-additive.

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: GRI 308: Supplier Environmental Assessment 2016 — 2016 edition. Retain the exact source edition on every observation; later editions require a separate method profile.

  • Environmental impact category.
  • Actual, potential or combined source state.
  • Significance method.
  • Supplier type, tier and location.
  • Assessment method and date.
  • Agreement date.
  • Improvement type.
  • Reporter versus supplier responsibility.
  • Retain the exact measurement-source edition with every observation.
  • A source-reported percentage using suppliers with improvement agreements as numerator and the compatible identified environmental-impact supplier cohort as denominator.

Record-specific limitations

  • An agreement does not establish a completed corrective action, remediation, verification, effectiveness, avoided impact or improved environmental performance. Improvements can include changes by the reporting organization itself.

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.
