Kern der Offenlegung
This asks the organisation to explain which Scope 3 categories are included in the emissions information it reports. In practice, the focus is on making clear the boundary of the Scope 3 figure: which upstream and downstream categories are covered, and whether any categories are left out or treated separately.
The practical point is comparability and completeness. A reader should be able to see whether the reported Scope 3 number reflects all relevant categories across the business, or only a selected set such as the most material ones, flagship operations, or categories where data are available. If coverage is partial, that should be clear from the disclosure.

Daten anfordern
Request the Scope 3 category evidence pack
Übersetzen Sie die Offenlegung in eine interne Geschäftsfrage — und passen Sie diese dann an die Sprache Ihrer Organisation an.
Which value-chain emissions categories are included in our reporting, which ones are left out, and what support do we have for the choices and calculation approach?
Use your organisation’s own labels for value-chain emissions, spend, logistics, purchased goods, travel, waste, and similar internal groupings first; then map them to the reporting categories only when you prepare the disclosure pack. Keep the request in the language the data owner already uses, and check the official source before sign-off.
Schwache Anfrage
Please provide the Scope 3 category disclosure inputs for the reporting period, including excluded categories, methodology, data mix, value-chain scope, and verified-data share.
Warum sie scheitert: This uses framework language that many internal owners will not recognise, so it is harder to action and easier to answer incompletely. It also does not tell the owner what their own files, labels, or evidence should look like, so the response may not be usable for the reporting pack.
Bessere Anfrage
Please send the value-chain emissions pack for [period] from your team’s own systems and working files. Use your normal internal category names first, then map them to the reporting categories if needed. Include what you covered, what you left out and why, the method and assumptions, the split between supplier/activity data and estimates, the coverage of the value-chain, and the share of data that has been checked or verified.
Vorlage für eine formelle E-Mail
Subject: Request for value-chain emissions category evidence pack Hi [name], I’m pulling together the reporting pack for [period] and need your help with the value-chain emissions section. Please could you send over the information for the areas your team owns, using your normal internal labels first and then, if helpful, mapping them to the reporting categories? I’m looking for: - which value-chain areas are included in this cycle - which areas are left out, and why - the method and main assumptions used - the split between supplier/activity data and estimated data - the scope of the value-chain covered - the share of data that has been checked or verified A simple table plus any supporting notes, files, or links would be ideal. Please include the period covered, the source system or file, and the person who prepared it. If anything is unclear, I’m happy to talk it through. Please also check the official source before sign-off. Thanks, [preparer name]
Kurzfassung für Teams / Slack
Hi [name] — could you share the value-chain emissions evidence for [period] from your team’s normal files/systems? I need: included areas, excluded areas and why, method/assumptions, primary vs estimated data split, coverage, and any checked/verified share. A table plus notes is fine. Please use your own internal labels first, then map if needed. Thanks — [preparer name]
Branchenbeispiele
Manufacturing
Kontext. A plant team tracks purchased materials, inbound freight, waste, and outsourced processing in separate operational files.
Angepasste Anfrage. Please share the emissions evidence pack for [period] from your plant reporting files. Use your own labels for materials, transport, waste, and outsourced work first, then map them if needed. Include what was covered, what was left out and why, the calculation method, the assumptions used, the split between supplier data and estimates, the value-chain areas covered, and the share of data that was checked.
Beispielantwort. Included: purchased steel, inbound road freight, production waste, and third-party coating. Excluded: employee commuting, because it was not assessed in this cycle. Method: supplier activity data for steel and freight; spend-based estimates for waste and coating. Primary data share: 58%. Checked data share: 41%.
Retail
Kontext. A retail sustainability team holds data on bought-in products, upstream transport, packaging, store waste, and some customer-use assumptions.
Angepasste Anfrage. Please send the value-chain emissions evidence for [period] from your retail reporting workbook and source files. Use your internal labels for product supply, logistics, packaging, store waste, and customer-related assumptions first, then map them if needed. Include included and excluded areas, reasons for any exclusions, the method and assumptions, the split between direct supplier data and estimates, the coverage of the value chain, and the share of data that has been checked or verified.
Beispielantwort. Included: bought-in products, inbound logistics, packaging, and store waste. Excluded: customer use of products, because the team has not modelled it this year. Method: supplier data for packaging and logistics where available; estimates for product categories with limited supplier detail. Primary data share: 46%. Verified data share: 29%.

Methodenhinweis
Set out the calculation basis in plain terms, including the assumptions used, how the boundary was drawn, which categories were included or left out, and whether any exclusions were due to practical limits.
Kontexthinweis
Explain what the figures represent in business terms, including how much of the value chain is covered, the mix of direct and indirect data, and the extent to which the underlying information has been checked.
Erläuterung zu Schwankungen
If the numbers move materially from one period to the next, point to the main drivers — such as a wider or narrower boundary, a different data mix, or changes in the share of checked information — and say whether the shift reflects a real change or a reporting-method change.

|---|---|---|
| We documented which parts of the wider value chain we left out of the coverage figure, and why those parts were not brought in. | An assurer will test whether the exclusions were chosen consistently, whether the reasons are specific rather than generic, and whether any omitted parts should have been included. | Boundary memo or methodology note; list of excluded categories; management rationale for each exclusion; review sign-off; any correspondence showing how the boundary decision was agreed. |
| Where we relied on an impracticability judgement, we recorded that conclusion and kept notes on how we are still handling the related emissions estimate in practice. | An assurer will probe whether the impracticability call was made on a supportable basis, whether it was applied only where needed, and whether the related emissions were still addressed through an appropriate process. | Impracticability assessment; internal approvals; working papers showing the estimation approach used instead; action plan or controls for ongoing handling; evidence of periodic reassessment. |
| We set out which value-chain categories were brought into the disclosed figure, and the list matches the scope we used in the working papers. | An assurer will check completeness and consistency: whether all intended categories were included, whether any category was accidentally left out, and whether the published list matches the calculation file. | Category mapping schedule; calculation workbook; consolidation or boundary checklist; draft-to-final comparison; sign-off from the preparer and reviewer. |
| Our method note explains how we measured the figure, including the main inputs we used and the assumptions we applied. | An assurer will test whether the method is described clearly enough to reproduce the result, whether the inputs are appropriate, and whether the assumptions are reasonable and consistently applied. | Methodology paper; calculation model; assumption log; source data extracts; version history showing changes and approvals. |
| We can show how much of the figure came from direct activity information from within the value chain, rather than from broader estimates alone. | An assurer will examine whether the stated mix of direct and indirect inputs is accurate, whether the direct activity data is sufficiently relevant, and whether the mix was calculated on a consistent basis. | Data source register; activity-level data files; allocation logic; calculation of the direct-input share; evidence of review over source selection. |
| Our boundary note makes clear which upstream and downstream parts were counted, and which related categories were left out. | An assurer will probe whether the boundary description is complete, whether the omitted categories were intentionally excluded, and whether the published wording matches the internal scope decision. | Boundary statement; category inclusion/exclusion matrix; internal scope papers; management review notes; final disclosure cross-check. |

Synthetisch, von LRA verfasst — nicht aus einem Unternehmensbericht und kein Text aus einem Standard.
:* we set out the value-chain emissions areas we left out, and why, because some upstream and downstream activities could not be measured with enough confidence for this reporting cycle. We also note where we relied on estimates rather than direct records, the parts of the chain covered by our review, and the main calculation choices and assumptions used.
- We included purchased goods and services, capital items, fuel- and energy-related activities, upstream transport and distribution, waste from operations, business travel, employee commuting, leased assets, downstream transport and distribution, processing of sold products, use of sold products, end-of-life treatment of sold products, and downstream leased assets; we excluded investments, franchises, and downstream processing where we had no reliable activity data, and we treated those exclusions as immaterial to the overall result.
- Our figures combine 68% primary records and 32% secondary factors; 74% of the total is based on data we had checked or had independently assured, while the rest comes from modelled or supplier-estimated inputs. We covered our own operations plus upstream and downstream activities across the full value chain, and we used spend-based factors where supplier-specific data were not available, distance-based methods for freight, and product-use assumptions based on expected lifetime and energy intensity.
Synthetic illustration for practitioner review only; not legal or compliance advice.
:* we explain which emissions areas were left out, the reason for each omission, and the point at which we judged further estimation to be too uncertain for this year’s report. We also describe the parts of the chain we covered, the mix of direct records and external factors, and the main assumptions behind the calculations.
- We reported on purchased goods and services, upstream transport and distribution, waste from operations, business travel, employee commuting, leased assets, downstream transport and distribution, use of sold products, and end-of-life treatment of sold products; we left out capital items, fuel- and energy-related activities, processing of sold products, investments, and franchises because the available information was too patchy or the activity was not material for our business model.
- Our dataset was 41% direct supplier or internal records and 59% third-party or modelled inputs; 62% of the total emissions figure rests on data that had been checked by an external party or otherwise verified, with the remainder unverified. We covered upstream, our own operations, and selected downstream stages, and we used average emission factors for missing supplier data, route-based freight estimates, and product-use assumptions tied to average customer behaviour and product life.

Szenarien zum Durcharbeiten
A preparer has mapped 11 upstream and downstream emissions categories for the year, but two of them were left out because the team could not obtain reliable activity data in time. The draft note also says those two areas were not included in the totals.
A group has included only purchased goods, transport, waste, and business travel in its value-chain emissions work because those were the only areas with usable data this year. The sustainability team is unsure whether it should also describe the wider set of categories it considered but did not include.
A preparer has built the calculation using a mix of supplier invoices, internal records, and industry averages. The team has also applied a few simplifying assumptions where direct measurements were unavailable, but these choices are only documented in working papers.
A company has complete supplier data for some categories, partial internal data for others, and industry-average estimates for the rest. The draft note says only that the figures are ‘based on available information’ and does not explain the data mix or the coverage of the value chain.

FAQ
Fragen, die diese Seite beantwortet
The page says to prepare a specific set of datapoints first: excluded categories, any impracticability note, the included Scope 3 list, calculation basis, data source mix, value chain boundary and verified data share. It also has a step-by-step preparation section you can use to turn those inputs into a draft.
Use the page’s preparation guidance to define the value chain boundary consistently before drafting, then keep that boundary aligned with the included Scope 3 list and the data source mix. The page is designed to help you document the boundary clearly rather than leaving it implicit.
The page tells you to prepare excluded categories as one of the core datapoints, so you should list what is left out and keep that visible in the draft. It also flags common reporting gaps, which is useful for checking that exclusions are explained rather than overlooked.
The page includes an evidence pack with five items and also sets out six assurance claims to verify, each with a claim, risk and evidence angle. That gives you a practical starting point for building an assurance-ready file before review.
Treat them as a checklist for what needs to be supported in the file: each claim is paired with the related risk and evidence to look for. The page is meant to help you test whether the draft is backed by enough documentation, not just whether the numbers are filled in.
The page has a section on common reporting gaps and mistakes, so it is worth using that as a final quality check before sign-off. In practice, it helps you spot missing boundary detail, weak methodology notes or unsupported figures early.
The Download Centre includes a Prep & Assurance workbook in .xlsx format, which is intended to support preparation and assurance readiness. Use it alongside the page’s datapoint list, evidence pack and draft-output section to organise the disclosure work.
The page includes synthetic illustrative examples, including a quantitative table, to show what a finished disclosure can look like. They are there to help you shape your own draft and check internal consistency, not to copy as a template.
The draft-output section gives visualisation ideas, narrative starters and a content-index line, so you can move from raw inputs to a readable disclosure. Use those prompts to explain the boundary, basis and data mix in plain language.
The page notes ESRS E1 (Climate Change) as the closest correspondence, so the same underlying data may be reusable where it fits your reporting setup. It does not say the requirements are identical, so you still need to check the page’s own datapoints and preparation steps.
