Short answer
The answer, before the reasoning
UK SRS S1 requires sustainability-related financial disclosures to cover the same reporting entity as the related financial statements. UK SRS S2 then requires the entity to measure and explain its GHG emissions using the GHG Protocol Corporate Standard unless a jurisdictional authority or exchange requires another method.
Scope 1 and Scope 2 emissions are disaggregated between the consolidated accounting group and other investees such as associates and joint ventures. Leased assets are classified according to the selected organisational-boundary approach and contractual facts, and may fall within Scope 1 or Scope 2 or within Scope 3 categories. Scope 3 requires consideration of the entire value chain and all 15 categories, with reassessment after significant changes such as acquisitions. There is not one universal “boundary”. A defensible report distinguishes the reporting entity, GHG organisational boundary, Scope 3 value-chain boundary, target boundary and any metric-specific perimeter, then reconciles them in one controlled memo.

Quick orientation
Quick orientation
- Applies to
- Groups, investment structures, property occupiers and owners, diversified entities and any reporter whose financial, operational and GHG boundaries differ.
- Primary decision
- How each legal entity, facility, investee, lease and value-chain category is treated in the reporting entity and in Scope 1, Scope 2 or Scope 3.
- Key sources
- UK SRS S1 paragraph 20 and B38; UK SRS S2 paragraph 29(a) and B23-B37; GHG Protocol Corporate and Scope 3 Standards.
- Common confusion
- Assuming that the financial-statement consolidation boundary automatically determines every GHG scope, or that lease accounting alone decides the emissions category.
Start with the reporting entity, then build the measurement boundaries
The sustainability-related financial disclosures are for the same reporting entity as the related financial statements. For consolidated financial statements, that means the parent and consolidated subsidiaries as one reporting entity. This rule anchors the entity whose prospects, cash flows, access to finance and cost of capital are being discussed.
The GHG inventory is a metric within that report, but its organisational and value-chain perimeters depend on the measurement method. UK SRS S2 requires use of the GHG Protocol Corporate Standard unless a relevant jurisdictional authority or exchange requires a different method. The entity explains its measurement approach, inputs, assumptions, reasons and changes.
The financial reporting entity anchors UK SRS, while organisational, investee, lease, Scope 3 and target boundaries are layered and reconciled.
In practice
| Boundary layer | Core question | Typical output |
|---|---|---|
| Reporting entity | Which entity is represented by the related financial statements? | Parent and consolidated subsidiaries, or the corresponding standalone reporting entity. |
| GHG organisational boundary | Which operations are included in Scope 1 and Scope 2 under the selected method? | Equity-share, financial-control or operational-control treatment, as applicable. |
| Other investees | How are associates, joint ventures and unconsolidated subsidiaries measured? | Separate disaggregation of Scope 1 and Scope 2 where included, plus method explanation. |
| Scope 3 value chain | Which upstream and downstream activities and entities are included? | Consideration of all 15 categories, category selection and measurement boundary. |
| Target boundary | Which scopes, entities and activities does the target cover? | Reconciliation to inventory and explanation of exclusions. |
| Metric-specific boundary | Does another climate metric use a different population? | Definition, reason and reconciliation for the specific metric. |
The GHG organisational-boundary choice
The GHG Protocol Corporate Standard provides approaches based on equity share or control. A control approach can be based on financial control or operational control. The selected approach affects which operations are included in Scope 1 and Scope 2 and which appear elsewhere in the value chain. The entity should apply the approach consistently and explain changes.
In practice
| Approach | General logic | Boundary control question |
|---|---|---|
| Equity share | Accounts for emissions according to the entity’s share of equity in operations, reflecting economic interest. | Are ownership interests and changes complete, current and supported? |
| Financial control | Includes operations over which the entity has financial control under the GHG method. | Does the control assessment align with the method and contractual facts, not only labels? |
| Operational control | Includes operations where the entity has authority to introduce and implement operating policies. | Which party actually controls operating policy, energy use, equipment and emissions decisions? |
| Jurisdictionally required method | A relevant authority or exchange may require another method for all or part of the inventory. | What is required, for which entities or emissions, and how is the resulting boundary explained and reconciled? |
Rule
IMPORTANT DISTINCTION
<p>The GHG organisational-boundary approach is not selected to produce the lowest emissions total or the easiest data collection. The entity applies the method and explains the resulting perimeters, assumptions and changes.</p>
Subsidiaries, associates, joint ventures and other investees
Consolidated subsidiaries
Consolidated subsidiaries form part of the UK SRS reporting entity. Their operational emissions treatment still follows the GHG method. Scope 1 and Scope 2 for the consolidated accounting group are disclosed as a disaggregated amount.
Associates and joint ventures
Associates and joint ventures are commonly outside the consolidated accounting group but may be included in Scope 1 or Scope 2 under the selected GHG measurement approach. UK SRS S2 requires Scope 1 and Scope 2 emissions to be disaggregated between the consolidated accounting group and other investees excluded from that group, including associates, joint ventures and unconsolidated subsidiaries.
If an investee is not included in Scope 1 or Scope 2 under the selected approach, its emissions may still be relevant in Scope 3, including Category 15 investments for appropriate activities. The classification must follow the method and facts rather than a blanket “all JVs are Scope 3” rule.
Minority interests and managed operations
Minority ownership does not, by itself, determine the GHG scope. Management contracts, operating rights, joint arrangements and actual authority can affect the control assessment. Keep the legal and operational fact record with the boundary conclusion.
Leased assets: accounting classification is not the whole answer
For GHG reporting, the treatment of a leased asset depends on the selected organisational-boundary approach and the contractual and operating facts. A lessee may include energy or fuel emissions from a leased asset in Scope 1 and Scope 2 when the asset falls within its organisational boundary. If it does not, relevant emissions can fall within Scope 3 Category 8, upstream leased assets. For a lessor, emissions outside its Scope 1 and Scope 2 may fall within Category 13, downstream leased assets.
In practice
| Situation | Possible treatment | Evidence to review |
|---|---|---|
| Lessee operates a leased building and controls energy procurement and operations | Scope 1 and Scope 2 may apply under the selected control approach. | Lease, utility contracts, metering, operating authority, equipment and energy decisions. |
| Lessee uses an asset outside its Scope 1/2 organisational boundary | Scope 3 Category 8 may apply. | Boundary policy, lease facts, landlord data, estimates and category methodology. |
| Lessor owns and leases an asset outside its Scope 1/2 boundary | Scope 3 Category 13 may apply. | Tenant energy data, common-area allocation, lease type, estimation and exclusions. |
| Shared or serviced space | Treatment may be split between direct energy, landlord-controlled energy and value-chain estimates. | Floor area, submetering, service charges, control rights, occupancy and allocation method. |
| Vehicle or equipment lease | Scope depends on operating control, fuel responsibility and method. | Contract, maintenance, fuel cards, telematics, asset control and period of use. |
Scope 3: consider the entire value chain and all 15 categories
UK SRS S2 requires the entity to consider its entire upstream and downstream value chain and all 15 GHG Protocol Scope 3 categories, and to disclose which categories are included. “Consider” is not permission to ignore difficult categories. The entity should perform a documented screening and explain measurement scope, exclusions, estimates and category boundaries.
1. Map the reporting entity’s purchases, capital goods, fuels and energy, logistics, waste, travel, commuting, leased assets, product use, end-of-life, franchises and investments.
2. Consider each of the 15 categories and document relevance, expected magnitude, influence, risk concentration, data availability and overlap.
3. Define the entities, counterparties, products, assets and periods included in each measured category.
4. Prevent double counting within the entity’s inventory while recognising that value-chain inventories of different entities can legitimately overlap.
5. Use reasonable and supportable information available without undue cost or effort when determining value-chain scope, as required by UK SRS.
6. Disclose included categories and sufficient method information to understand the sources of Scope 3 emissions.
7. Reassess after a significant event or change in circumstances, including material changes in value chain, business model, corporate structure or climate exposure.
Acquisitions, disposals and other group changes
Group changes can affect the financial reporting entity, the GHG organisational boundary, Scope 3 categories, target boundary and comparatives in different ways. The reporting team should not use a single “M&A adjustment” without identifying which record is changing.
A boundary reconciliation separates the effects of consolidation, GHG method, investees, leases, Scope 3 and target recalculation when the group changes.
In practice
| Record | Acquisition or disposal question | Controlled response |
|---|---|---|
| Reporting entity | Was the entity consolidated in the related financial statements and for what period? | Reconcile to the finance consolidation schedule and reporting date. |
| Scope 1 and Scope 2 inventory | When did the operation enter or leave the selected organisational boundary? | Apply the method, document period-of-control data and explain measurement effects. |
| Other investees | Did ownership or control change without full consolidation? | Update disaggregation and investment or value-chain treatment. |
| Scope 3 | Did the transaction expand or alter products, suppliers, customers, assets or investments? | Reassess affected categories and entities after significant change. |
| Target baseline | Does the approved target-recalculation policy require adjustment? | Explain the recalculation, continued comparability and effect on performance. |
| Comparatives | Is a change due to group composition, metric redefinition, new information or error? | Apply the appropriate UK SRS S1 comparative rule and disclose the nature of the change. |
In practice

Hypothetical example: joint venture and leased warehouses
The group includes stores and the distribution subsidiary in the consolidated accounting group amount. It concludes that it does not have operational control over the logistics JV, so the JV is not included in group Scope 1 and Scope 2 under that approach; relevant emissions are assessed in the value chain. Two warehouses operated and energy-controlled by the group are included in Scope 1 and Scope 2, while a serviced warehouse controlled by the landlord is assessed in Category 8 using landlord data and estimates. The memo records the contracts, control analysis, data sources and disaggregation.
Hypothetical scenario

Illustrative boundary disclosure
The wording is only credible if the entity has a complete group structure, method decision, lease analysis, Scope 3 screening, M&A change log and reconciliation to the disclosed amounts.
Hypothetical scenario
ILLUSTRATIVE WORDING — ADAPT TO FACTS
<p>The sustainability-related financial disclosures cover the parent and subsidiaries included in the consolidated financial statements. Greenhouse gas emissions are measured using the GHG Protocol Corporate Standard and the operational-control approach. Scope 1 and Scope 2 emissions are disaggregated between the consolidated accounting group and other investees included under the measurement method. The Group considered all 15 Scope 3 categories and reports the categories identified in the Scope 3 note. Material leased assets are classified according to operating control and contractual responsibility; the boundary reconciliation explains Category 8 and Category 13 treatment. Acquisitions and disposals are assessed at completion for inventory, value-chain and target-boundary effects.</p>

In practice
Weak versus stronger practice
| Weak statement | Problem | Stronger approach |
|---|---|---|
| “The emissions boundary equals the financial boundary.” | Ignores the GHG method, other investees, leases and Scope 3. | Anchor the report to financial statements and separately explain GHG and value-chain perimeters. |
| “All JVs are Scope 3.” | Classification depends on the selected measurement approach and facts. | Assess each material investee and disclose group/other-investee disaggregation. |
| “Leased offices are landlord emissions.” | Lease accounting or invoicing alone does not determine GHG scope. | Assess operational or financial control, energy responsibility and Category 8/13 treatment. |
| “M&A changed the number, so comparatives were restated.” | Does not identify composition, method, target or error treatment. | Use separate change records and apply the appropriate comparative or target-recalculation policy. |
| Only measured Scope 3 categories are listed. | No evidence that all 15 categories were considered. | Maintain a complete screening and disclose categories included and material exclusions or limitations. |
Common review findings
The reporting entity cannot be reconciled to the related financial statements.
The GHG organisational-boundary approach is not identified or is changed without explanation.
Scope 1 and Scope 2 are not disaggregated between the consolidated accounting group and other investees.
Associates and joint ventures are classified by ownership percentage alone.
Lease treatment follows IFRS lease accounting labels without reviewing GHG control and operating facts.
Landlord or tenant emissions are omitted because utility invoices are held by the other party.
Scope 3 screening does not cover all 15 categories or the entire value chain.
Acquisitions and disposals are not reflected consistently across the inventory, value chain and targets.
Target and inventory boundaries differ without a reconciliation.
Comparative restatement, estimate updates and target rebaselining are mixed together.
Myth
“Once the finance consolidation perimeter is known, the Scope 1, Scope 2 and Scope 3 boundaries are automatic.”
Reality
The financial reporting entity anchors the UK SRS disclosure, but GHG scopes depend on the required or selected measurement approach, investee and lease facts, value-chain categories and target definitions. The differences must be documented and reconciled.
Readiness
Pre-publication checklist
- The UK SRS reporting entity reconciles to the related financial statements and group structure.
- The GHG measurement method and organisational-boundary approach are identified and approved.
- Scope 1 and Scope 2 amounts distinguish the consolidated accounting group and other investees.
- Each material associate, JV and unconsolidated investee has a documented treatment.
- Material leases have a contractual and operational-control assessment.
- Category 8 and Category 13 populations are complete where relevant.
- All 15 Scope 3 categories and the entire value chain have been considered.
- Scope 3 included categories, boundaries, estimates and exclusions are disclosed and evidenced.
- Acquisitions, disposals and significant changes trigger boundary reassessment.
- Target boundaries and baseline treatment reconcile to the inventory.
- Comparative changes distinguish composition, methodology, estimates, errors and target recalculation.
- Finance, GHG, legal, property, investment and procurement owners have reviewed the memo.
Self-check
- Can every entity and material leased asset be traced to a financial, Scope 1/2 or Scope 3 treatment?
- Does the disaggregation make the consolidated accounting group distinct from other investees?
- Has the team considered all 15 Scope 3 categories rather than only those with available data?
- Would an acquisition or disposal trigger the right inventory, value-chain, target and comparative decisions?
