Objet de l’information
This disclosure asks an organisation to report its total gross greenhouse gas emissions in absolute terms, rather than as an intensity measure. In practice, that means showing the full amount of emissions generated before any offsets or removals are considered, so readers can see the scale of the organisation’s climate impact.
The practical focus is on completeness and consistency of coverage. Organisations should think about whether the figure covers all relevant operations, entities and activities in scope, rather than only selected sites or headline locations, so the reported number reflects the organisation as a whole.

Comment le préparer
Demander les données
Request the emissions totals and working papers from EHS / Operations
Traduisez l’information en une question métier interne, puis adaptez-la au vocabulaire de votre organisation.
What are the organisation’s gross greenhouse gas totals for the reporting period, split by direct, purchased energy, and other value-chain sources, and what calculation perimeter was used?
Use your organisation’s own terms first, then map them to the reporting labels. For example, ask for your carbon inventory, emissions workbook, or footprint pack if that is how the team talks internally; only translate into the reporting labels when you prepare the disclosure pack. Check the official source before sign-off.
Demande faible
Please send the Scope 1, Scope 2, Scope 3 and total gross emissions data for the disclosure.
Pourquoi elle échoue : It uses reporting labels only, which may not match how the owner stores or tracks the data. It does not ask for the perimeter, source files, assumptions, exclusions, or review evidence needed to understand what sits behind the totals.
Meilleure demande
Please send the latest carbon inventory pack for [reporting period] for [entity/group name]. We need the perimeter used, the totals for direct emissions, purchased energy emissions, and other value-chain emissions, plus the gross total in tCO2e, together with the workbook/export, assumptions, exclusions, estimates, and any review note. Use your team’s usual labels first, then add a short mapping to the reporting labels.

Modèles pédagogiques LRA — adaptez-les à votre organisation et vérifiez la source officielle avant validation.
Note méthodologique
State the boundary used for the figures, explain how each emissions source was defined for the calculation, and note that the totals combine the included source categories on that basis.
Note de contexte
Explain what the figures show in practice by linking the boundary to the reported totals and clarifying how the direct, energy-related and value-chain amounts sit within the overall emissions picture.
Déclaration sur les variations
If any figure moved materially, describe the main operational or boundary-related drivers behind the change and note whether the shift came from one source category or across the full emissions set.

Pour chaque affirmation, vérifiez les preuves
| Affirmation | Risque | Preuves à vérifier |
|---|---|---|
| We set the boundary for the figure by fixing the reporting year, the group of entities included, and the part of the value chain we treated as in-scope. | Assurer checks whether the boundary was chosen consistently, whether any exclusions were justified, and whether the same boundary was used across the related figures. | Boundary memo; consolidation list; scope mapping; methodology paper; sign-off showing the period, entity boundary and value-chain boundary used. |
| Where we used direct readings of gases, we converted them into carbon-dioxide equivalent using the warming values current at the reporting date from the latest available assessment. | Assurer probes whether the conversion factors were current, whether the correct assessment was used, and whether the conversion was applied consistently to all directly measured gases. | Conversion-factor source file; version/date of the assessment used; calculation workbook; review notes showing the conversion was applied to direct measurements. |
| Where we estimated emissions from activity data, we matched each input to a relevant factor and then converted the result into carbon-dioxide equivalent. | Assurer checks whether the factors were suitable for the activity, whether the chosen basis was documented, and whether the conversion to carbon-dioxide equivalent was done correctly. | Emission-factor library; factor selection rationale; activity data extracts; calculation sheets; evidence of review of factor applicability. |
| We prepared the disclosed emissions using the reporting period, the organisational boundary and the value-chain boundary we documented for the calculation. | Assurer probes whether the disclosed numbers align with the stated perimeter and whether any parts of the business or value chain were omitted without explanation. | Perimeter note; organisational chart or consolidation schedule; value-chain boundary analysis; reconciliation from source data to the disclosed totals. |
| For value-chain data drawn from different years, we used the timing basis allowed in our method and flagged any material events that happened in between. | Assurer checks whether the timing approach was permitted, whether the periods were mixed consistently, and whether important changes between dates were identified and explained. | Timing policy; source-data dates; bridge or adjustment schedule; narrative on intervening events; evidence of review of material changes. |
| We converted any directly measured gases in the same way across the related figures, using the current warming values at the reporting date. | Assurer probes whether the same conversion basis was used consistently and whether the date-specific factors were correct for the reporting period. | Calculation workbook; factor source and date; control checklist; reviewer sign-off. |

We set out the boundary used for this emissions figure as our full consolidated group, covering operations we control and the value-chain activities we have included for the year ended 31 December 2025.
- Direct fuel and process emissions: 12,400 tCO2e.
- Purchased electricity and other energy emissions: 8,600 tCO2e.
- Other value-chain emissions: 79,000 tCO2e.
- Combined gross emissions: 100,000 tCO2e.
This example shows a simple narrative disclosure that identifies the reporting boundary and then gives the three emissions buckets plus the overall total. The figures are internally consistent because 12,400 + 8,600 + 79,000 = 100,000.
For the year ended 31 March 2026, we measured emissions across our consolidated group and the related activities we chose to include in the reporting boundary.
- Emissions from our own sites and vehicles: 3,200 tCO2e.
- Emissions from bought-in power: 1,800 tCO2e.
- Emissions from the wider supply chain and downstream activities included in the boundary: 15,000 tCO2e.
- Total gross emissions for the period: 20,000 tCO2e.
This example uses different plain-language labels for the same required information, while still showing the boundary and the three component amounts that add up to the total. The arithmetic is consistent because 3,200 + 1,800 + 15,000 = 20,000.

Scénarios à travailler
A group has measured emissions for its UK operations and overseas sites, but the draft table only shows the combined figure and the team is unsure whether to split out the three source categories. The underlying working papers do distinguish direct fuel use, purchased energy, and other value-chain emissions.
A preparer has finalised the emissions workbook and finds that the total gross figure is 18,400 tCO2e. The source lines are 2,900 tCO2e for direct fuel use, 4,100 tCO2e for purchased energy, and 11,400 tCO2e for other value-chain emissions, which add exactly to the total.
A company has used a market-based method for purchased electricity in its internal reporting, but the disclosure pack also includes location-based results in a separate appendix. The reporting team is unsure which set belongs in this item.
A preparer has a draft that lists Scope 1 and Scope 2 amounts, but Scope 3 is still being estimated and the team wants to publish the first two lines now, leaving the third line blank for later. The total gross figure has not yet been finalised.

FAQ
Questions auxquelles cette page répond
Start with the plain-language explainer and the step-by-step preparation section, then use the datapoints list to gather the figures you need. The page also gives narrative starters and a content-index line to help turn the data into a draft.
The page says to prepare the reporting boundary, direct emissions total, purchased energy emissions, value chain emissions and gross emissions total. Having those items ready should make it easier to complete the draft and check the numbers are internally consistent.
The page flags reporting boundary as one of the datapoints to prepare, so it should be set before you build the disclosure. Use the step-by-step preparation section to work through the scope in a structured way.
The page is designed for sustainability and ESG managers, HR or data owners, and assurance reviewers, so ownership should sit with the people who can source and explain each datapoint. Use the workbook to assign tasks and track who is responsible for each item.
The page includes an evidence pack with five items and also lists six assurance claims to verify using claim, risk and evidence. Use those sections together so you can show where each figure came from and why it is reliable.
The page has a section on common reporting gaps and mistakes, which is useful for checking whether your draft is missing a datapoint or has an unclear boundary. Review that section before finalising the numbers and narrative.
The workbook is listed in the Download Centre and is meant to support preparation and assurance readiness. Use it to organise the required datapoints, track evidence, and work through the page’s step-by-step preparation process.
Yes — the Download Centre includes a printable Library Card, which is useful as a quick reference for the disclosure. It can help a data owner see the key datapoints, the assurance focus and the draft-output prompts in one place.
The page includes synthetic illustrative example disclosures, including a quantitative table where relevant, so you can see how the disclosure might look when drafted. Treat it as a model for structure and presentation, not as real company data.
Use the draft-output section, which gives visualisation ideas, narrative starters and a content-index line. That section is designed to help you move from prepared data to a readable draft.
The page notes ESRS E1 (Climate Change) as the closest correspondence, so it can help you think about reuse of climate data across frameworks. It does not say the requirements are identical, so you should still check the disclosure-specific page content before relying on the data.
