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
Metric 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.
- Pillar
- Environmental
- Topic
- Supplier environmental assessment
- Controlled domain
- Supply chain and value chain
- Entity type
- Metric
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.

Formula
P = (N ÷ D) × 100Use the source-defined numerator and denominator for the same population, period, boundary, and method; do not infer an unstated denominator.
Variables
| Symbol | Variable | Definition | Unit |
|---|---|---|---|
N | qualifying numerator | Qualifying observations within the qualifying population and boundary defined for Suppliers with significant negative environmental impacts where improvements were agreed. | Dimensionless |
D | declared denominator | Complete compatible denominator for the qualifying population and boundary defined for Suppliers with significant negative environmental impacts where improvements were agreed. | Dimensionless |

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.

- 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.
