C.3Determine reporting scope, boundaries and perimeter
Working Draft version 1.1
Purpose and scope
This unit covers the capability to determine and document the entities, operations, activities, business relationships, value-chain stages, geographies, topics, metrics, time periods and information sources included in sustainability reporting. It requires reconciliation of legal, financial, operational, value-chain and topic-specific boundary concepts and transparent treatment of exclusions, changes and limitations. It follows the reporting-basis decision in A.3 and the business-model map in B.2.
Applied competency statement
Can determine and document the organisational, operational, value-chain, topic, metric and time boundaries relevant to sustainability reporting and reconcile differences from financial consolidation and other organisational perimeters.
Boundary and escalation
This unit owns the organisation-wide reporting perimeter under the approved reporting basis. E.2 owns metric-specific boundaries, E.5 implements consolidation and disaggregation, B.2 maps the business model and value chain and A.3 owns applicability. It does not provide corporate-law, accounting, consolidation, contractual or legal-responsibility opinions.
Key quality risks
Assuming the financial consolidation boundary automatically answers every sustainability reporting question; omitting material operations, sites, joint arrangements or business relationships; applying one boundary to all topics and metrics; double counting or gaps between entities and value-chain stages; unrecorded exclusions; inconsistent periods; changes without restatement or explanation; and using data availability to define the reporting perimeter.

| C.3 | G.8 | Risk and control linkage | Boundary consistency must be maintained across narratives, metrics, reports and external channels. |
| C.3 | C.5 | Feeds into | Impact-materiality assessment must operate within an explicit organisational and value-chain scope while remaining alert to missing impacts. |
| E.2 | C.3 | Boundary distinction | Metric-specific boundaries should be reconciled to the approved reporting perimeter. |
| E.3 | C.3 | Boundary distinction | Target and baseline scope should be reconciled to reporting and metric boundaries. |
| E.5 | C.3 | Prerequisite | The approved reporting perimeter defines the expected consolidation population. |
