IFRS S1 Reporting Entity and Boundary: Financial Statements, Value Chain and GHG Data

Boundary problems usually arise because teams use the words “group”, “value chain” and “GHG boundary” as though they mean the same thing. They do not. The reporting entity answers whose prospects the sustainability-related financial disclosures explain. The value chain identifies where relevant interactions, resources, dependencies, risks and opportunities occur. A metric boundary identifies which entities, operations or activities enter a particular calculation. A well-prepared report keeps these layers connected but distinct.

The reporting entity, value chain and metric boundary are related, but each answers a different reporting question.

IFRS S1 paragraph 20 requires sustainability-related financial disclosures for the same reporting entity as the related financial statements. The disclosures must also identify the financial statements to which they relate. The rule prevents a sustainability report from silently using a narrower or broader entity than the financial report while presenting the results as a connected set of general purpose financial reports.

For consolidated financial statements, IFRS S1 B38 explains that the reporting entity comprises the parent and its subsidiaries as a single reporting entity. The sustainability disclosure should therefore enable users to understand how sustainability-related risks and opportunities affect the prospects of that group. Internal operating segments, legal entities and sites can be used for data collection and disaggregation, but they do not replace the group-level reporting entity.

Associates and joint ventures are often accounted for differently from consolidated subsidiaries. They may therefore sit outside the consolidated accounting group while remaining economically important to the reporting entity. IFRS S1 does not solve the boundary question by saying “include every investee” or “exclude everything outside consolidation”. Instead, the entity assesses how the relationship gives rise to sustainability-related risks or opportunities that could affect its prospects and which information is material to explain them.

The table is a practical orientation, not accounting advice. The exact classification and consolidation treatment must be taken from the related financial statements and applicable accounting framework.

IFRS S1 defines the value chain as the full range of interactions, resources and relationships related to the reporting entity’s business model and external environment. It includes operations as well as supply, marketing and distribution channels, product use and end-of-life, financing, and the geographical, geopolitical and regulatory environment. The value-chain lens is therefore not limited to contractual suppliers and customers or to entities over which the reporting entity has control.

Value-chain information is matter-specific. A labour-practices risk may be concentrated among labour agencies and high-risk suppliers; a product-safety risk may extend to distributors and end users; a bank’s climate exposure may be concentrated in borrowers and investees. The scope should be reassessed when a significant event or significant change in circumstances occurs, including a material change in the business model, corporate structure or value chain.

Map the upstream and downstream activities that create, transmit or concentrate each material risk or opportunity.

Identify the relationship type, geography, activity and dependency rather than relying only on legal ownership.

Distinguish information needed to identify the matter from information needed to measure a particular metric.

Use reasonable and supportable information available without undue cost or effort where the Standard provides that mechanism.

Document material gaps and estimation methods instead of treating outside-group data as automatically unavailable.

A metric can use a boundary that differs from the reporting entity because the applicable Standard or measurement methodology defines the population differently. Employee metrics might include only employees or also non-employee workers; water metrics may focus on facilities in stressed areas; an industry metric may use a production or revenue boundary; GHG emissions use organisational and value-chain concepts. Each published metric should therefore carry its own boundary record, even when many metrics use the same group perimeter.

IFRS S2 requires disclosure of absolute gross Scope 1, Scope 2 and Scope 3 greenhouse gas emissions, subject to the Standard’s detailed requirements and reliefs. For Scope 1 and Scope 2, paragraph 29(a)(iv) requires disaggregation between the consolidated accounting group and other investees included in the measurement, such as associates, joint ventures or unconsolidated subsidiaries. This disaggregation makes the relationship between the financial-statement perimeter and the GHG measurement boundary visible.

IFRS S2 also requires disclosure of the GHG measurement approach, inputs and assumptions. When the GHG Protocol Corporate Standard is used, the entity identifies whether it applies an equity-share or control approach and explains the choice and its relationship to the disclosure objective. The GHG measurement boundary can therefore differ from the accounting consolidation boundary. The report should not imply that “operational control” and “financial control” are equivalent simply because both are called control.

Scope 3 is different again. It covers indirect emissions in the upstream and downstream value chain and requires consideration of all 15 Scope 3 categories. IFRS S2 requires disclosure of the categories included and information about measurement inputs and assumptions. A Scope 3 boundary is therefore not created by adding all entities outside consolidation; it is developed category by category based on value-chain activities, methodology and the Standard’s requirements.

The following hypothetical example shows how one reporting entity can use several measurement boundaries without confusing users. The facts and conclusions must be adapted to the entity’s accounting basis, GHG method and applicable ISSB requirements.

A metric-by-metric reconciliation prevents the accounting, GHG and value-chain boundaries from being presented as interchangeable.

A consolidated industrial group owns 50% of a joint venture that operates a high-emitting processing facility. The joint venture is equity-accounted and is not part of the group’s consolidated accounting group. The group uses an operational-control approach for its GHG inventory and does not control the joint venture’s operations. The joint venture’s emissions are therefore excluded from the group’s Scope 1 and Scope 2 organisational boundary but are included in the relevant Scope 3 treatment based on the applicable methodology. A separate capacity metric includes the group’s share of joint-venture production because management uses it to assess transition exposure.

The disclosure identifies the group as the IFRS S1 reporting entity, explains the joint venture’s accounting treatment and material transition exposure, states the GHG organisational approach, discloses the required GHG categories and explains why the production metric has a different boundary. The result is not one universal boundary; it is a transparent reconciliation of three different measurement purposes.
