Foco de la divulgación
This asks an organisation to explain how it has set the boundary for its greenhouse gas reporting and to break that boundary down in a way that makes the coverage clear. In practice, the focus is on showing whether the figures relate to the whole organisation, only certain parts of it, or a mix of locations, activities or entities, so readers can see what is included and what is not.
It also asks for the details needed to understand Scope 2 reporting within that boundary. The practical point is to make the reported Scope 2 information traceable to the parts of the business it covers, rather than leaving users to assume it applies across all operations or only selected sites.

Preparación
Información clave que preparar
| Campo de preparación | Qué recopilar | Pista de evidencia | Responsable |
|---|---|---|---|
| Boundary explanation | A plain explanation of which parts of the business are included in the reported emissions set, and any exclusions or changes in coverage, so readers can see how the reporting perimeter was drawn. | Group reporting memo, consolidation notes, boundary decisions paper, and any mapping between the reporting perimeter and the entities or operations included. | Group reporting / Sustainability reporting |
| Group emissions total | The emissions figure for the whole consolidated group, using the same group structure and reporting period as the financial consolidation basis. | Consolidated emissions workbook, group reporting pack, and the final figure signed off against the consolidation perimeter and reporting period. | Sustainability reporting / Finance |
| Market-based electricity context | The explanation needed to show how electricity emissions are treated when contractual arrangements are used, including the basis applied and the related context for the reported figure. | Energy procurement records, contractual instrument register, supplier statements, and the calculation file showing how the market-based approach was applied. | Energy / Sustainability reporting |
| Grid electricity emissions | The emissions figure calculated from the standard grid-average approach for purchased electricity, using the relevant consumption data and the location basis applied for the reporting period. | Utility bills, meter data, site consumption schedule, and the calculation workbook used for the grid-average electricity emissions result. | Energy / Sustainability reporting |
| Other investee emissions | The emissions attributed to investees other than those already captured elsewhere in the reporting set, expressed in tonnes of CO2e and based on the chosen investee coverage. | Investee inventory, ownership or influence mapping, underlying emissions data from investees, and the calculation file supporting the attributed total. | Investment reporting / Sustainability reporting |

Request the emissions boundary and Scope 2 detail pack
Traduzca la divulgación a una pregunta de negocio interna y adáptela después al lenguaje propio de su organización.
Can you provide the boundary note and the supporting emissions figures needed to explain which parts of the group are included, how the electricity-related emissions are treated, and what other investee emissions are in scope for the reporting period?
Use your organisation’s own terms first, then map them to the reporting labels. For example, if you talk about the group perimeter, energy reporting, portfolio holdings, or market-based electricity, keep those internal terms in the request and only translate them at the end for reporting review. This is a possible LRA training template; adapt this to your organisation and check the official source before sign-off.
Solicitud débil
Please provide the IFRS S2 boundary disaggregation and Scope 2 details for the disclosure.
Por qué falla: This uses framework language only, so the owner has to guess what internal records are needed. It does not say which systems, figures, or explanatory notes to pull, and it gives no clue about the organisation’s own perimeter, electricity, or investee terminology.
Solicitud mejor
Please send the group perimeter note, the consolidated emissions figure, the electricity accounting context, the location-based electricity emissions number, and any other investee emissions for [period], with source file, assumptions, and reviewer. Use your internal terms first, then we will map them for reporting review.

Nota metodológica
Set out how the reporting boundary was drawn, including which parts of the business and which holdings were brought into the calculation, and explain the basis used for each emissions measure.
Nota de contexto
Explain what each figure is intended to show: the group total on the chosen boundary, the electricity-related result under the local-grid approach, the contract-adjusted view, and any emissions linked to investments or other holdings.
Declaración sobre las variaciones
If any measure moved materially, describe whether the change came from real operational shifts, changes in the reporting boundary, or the use of different electricity-accounting inputs.

| Afirmación | Riesgos | Evidencia que comprobar |
|---|---|---|
| We split the reported figure between the entities we control in our reporting group and the holdings we keep outside that group, so the reader can see each part separately. | The split may be unclear, inconsistent with the consolidation basis, or include/exclude holdings incorrectly. | ['Group boundary paper showing which entities are in the reporting group and which are outside it', 'Working papers reconciling the split to the final reported totals', 'Entity list or ownership schedule used to classify each holding', 'Review notes showing the boundary decision was checked before publication'] |
| We kept a short boundary note explaining how we decided what sits inside the reported group and what sits outside it. | The boundary explanation may be too vague to support the split, or may not match the numbers reported. | ['Boundary narrative or methodology note used for the disclosure', 'Cross-reference from the note to the calculation file', 'Approval trail showing the note was reviewed alongside the figures', 'Version history confirming the final wording matches the final numbers'] |
| We calculated the figure for the group we report on using the same source files and cut-off date across the whole set of operations. | Different sites or periods may have been treated differently, creating an uneven or incomplete coverage basis. | ['Data collection instructions and reporting timetable', 'Source extracts from all included operations', 'Consolidation or coverage checklist showing completeness', 'Exception log for any late, missing or estimated inputs'] |
| We separately captured the emissions linked to holdings we do not include in the main reporting group, so they are not mixed into the group total. | Outside holdings may have been double-counted, omitted, or wrongly folded into the main total. | ['Schedule of excluded holdings and their reported emissions', 'Reconciliation showing no overlap with the group total', 'Ownership or control evidence supporting the classification', 'Reviewer sign-off on the separation of the two buckets'] |
| For the electricity-related part of the figure, we kept both the local-grid view and the instrument-backed view in the working papers, even where only one view is shown in the final table. | The supporting basis for the electricity figure may be incomplete, or the wrong basis may have been used in the disclosure. | ['Calculation file showing both electricity views where applicable', 'Source data for grid factors and any instrument records used in the calculation', 'Method note explaining how the electricity figure was prepared', 'Internal review confirming the disclosed basis matches the underlying workings'] |
| We held the contractual records and related support needed to explain the electricity figure, and we checked that they were current and traceable before release. | The supporting records may be stale, incomplete, or not traceable to the reported number. | ['Register of contractual records used in the calculation', 'Copies of contracts, certificates, or other supporting documents', 'Traceability check from each record to the final figure', 'Pre-publication review showing the records were current for the reporting period'] |

Sintéticos, redactados por LRA: no proceden del informe de ninguna empresa ni del texto de ninguna norma.
We describe the reporting perimeter used for our climate metrics by showing which entities sit inside our group reporting boundary and which holdings are left outside it. For this example, our consolidated group covers 100,000 tCO2e of Scope 2 emissions on a location-based view and 92,000 tCO2e on a market-based view, with the gap reflecting our use of electricity contracts and certificates.
- Our share of emissions from investees that we account for outside the group boundary is 18,000 tCO2e, shown separately so readers can see the effect of those holdings on the wider footprint.
- In this illustration, the market-based figure is lower than the location-based figure because contractual electricity arrangements reduce the amount we report under the market view.
This example shows how to explain the reporting boundary, the group total, the two ways of viewing purchased electricity emissions, and emissions from holdings outside the consolidation boundary.
We set out the scope of our climate reporting by explaining which operations are included in our group figures and which investments are kept outside that perimeter. For this example, our consolidated group records 54,000 tCO2e using the local-grid method and 49,500 tCO2e using the contract-adjusted method, with the difference arising from electricity supply agreements.
- The emissions linked to investees that are not brought into the group total amount to 6,500 tCO2e, presented separately to show the wider exposure from those interests.
- This split helps readers compare the physical electricity footprint with the figure that reflects our contractual electricity position.
This example shows the same disclosure points in a different sector, using a different set of internally consistent figures and wording.

Escenarios para trabajar
A group prepares its climate note on a consolidated basis, but one subsidiary is held for sale and is excluded from the group totals used elsewhere in the report. The team is unsure whether the boundary note should explain that exclusion and how it affects the emissions figures shown.
A preparer has both a supplier-backed electricity certificate programme and a separate utility tariff arrangement. They have a market-based Scope 2 figure ready, but the working papers do not yet explain what instruments sit behind it or how they affect the result.
A company reports a market-based electricity number for its offices and warehouses, but the sustainability team only has a single combined electricity total from the utility bills. They are unsure whether they also need a figure based on the grid mix where the sites are located.
An investment holding company has a small portfolio of associates and joint ventures. Its climate team has calculated 18,400 tCO2e from those other investees, but the draft note only says the amount is included in the total and does not separate it out.

Preguntas frecuentes
Preguntas que responde esta página
The page says to prepare five datapoints: a boundary explanation, group emissions total, market-based electricity context, grid electricity emissions, and other investee emissions. Use those as the starting checklist before you draft anything.
Use it as a working sequence for collecting the required inputs, checking the boundary, and then turning the information into a draft. The page is set up to help you move from raw data to a disclosure-ready narrative.
The page flags boundary explanation as one of the datapoints to prepare, so you should be ready to explain the scope used for the disclosure. Keep the explanation aligned to the data you are reporting and the evidence you can show.
The page is designed for sustainability/ESG managers, HR or data owners, and assurance reviewers, so ownership should sit with the people who can source, explain, and evidence the datapoints. The workbook and evidence pack are there to help you assign and track that work.
The page includes an evidence pack with five items for assurance readiness. Use it to assemble the supporting material behind the boundary explanation, emissions figures, and any context you include.
The page says there are six assurance claims to verify, each with a claim, risk, and evidence angle. Use them as a checklist to test whether your draft is supported and whether the evidence pack is complete.
The page lists common reporting gaps and mistakes so you can spot weak points before you finalise the disclosure. It is useful for checking whether your boundary, emissions data, and supporting narrative line up.
The Download Centre includes a Prep & Assurance workbook in .xlsx format, which is intended to help you organise the preparation and assurance work. Use it alongside the page’s draft-output section to turn the inputs into a first draft.
The Download Centre includes a printable Library Card in .pdf format, which is a quick reference for the page content. It is useful if you want a compact checklist while you are gathering data or reviewing a draft.
It includes synthetic illustrative example disclosures, including a quantitative table where relevant. Treat them as examples of how to present the information, not as real company data.
The draft-output section gives visualisation ideas, narrative starters, and a content-index line. Use those prompts to shape the wording and structure of your first draft once the data is assembled.
The page says ESRS E1 (Climate Change) is the closest correspondence, so the data may be reusable across frameworks. It does not say the requirements are identical, so you should still check the other framework’s own disclosure needs.
