Foco de la divulgación
This disclosure asks an organisation to report its direct greenhouse gas emissions from sources it owns or controls. In practice, that means the emissions created by the organisation’s own activities, such as fuel burned in company vehicles, boilers, generators or other on-site equipment, rather than emissions from suppliers or customers.
The practical focus is on the organisation’s full operational footprint, not just a few prominent sites. Teams should think about where direct emissions arise across the business and make sure the reporting boundary is applied consistently so the figure reflects the organisation’s own operations as a whole.

Traduzca la divulgación a una pregunta de negocio interna y adáptela después al lenguaje propio de su organización.
What is our total direct greenhouse gas emissions figure for the reporting year, and what boundary, method, period and source list support it?
Use your organisation’s own terms first for the team, systems and asset groups involved, then map them to the reporting labels in the pack. Keep the ask in business language your colleagues already use, and check the source material before sign-off.
Solicitud débil
Please provide the Scope 1 evidence for the disclosure.
Por qué falla: It uses framework language only, so the owner may not know which team records, systems or assets to pull. It also does not say what period, sources, method or total should be included, so the response may be incomplete or hard to verify.

Nota metodológica
State which parts of the business were included in the calculation, name the approach used to quantify the figures, and note the time window covered by the data.
Nota de contexto
Explain that the figures represent the organisation’s direct climate impact from the activities counted in the inventory, rather than a wider value-chain view.
Declaración sobre las variaciones
If the total moved materially, point to the main operational drivers, changes in included sources, or any shift in the calculation basis that affected the result.

Preparación para el aseguramiento
Para cada afirmación, compruebe la evidencia
| Afirmación | Riesgos | Evidencia que comprobar |
|---|---|---|
| I prepared the coverage figure using the group structure and control position that applied in the reporting year, and I checked whether any acquisitions, disposals or other structural moves changed what should be included. | The assurer will test whether the boundary was set consistently, whether all relevant owned or controlled sources were brought in, and whether changes in the business were reflected correctly. | Group structure chart; legal entity and operational control mapping; acquisition/disposal register; boundary memo; year-end consolidation papers; management sign-off on inclusion/exclusion decisions. |
| I treated the disclosed operations as covering sources we own or directly run, wherever they sit geographically, and I documented any exclusions with a clear reason. | The assurer will probe whether the scope is complete across locations and whether any omitted sources were left out for a defensible reason rather than convenience. | Asset and site register; control assessment; list of included and excluded sources; rationale for exclusions; site-level inventory; internal review notes. |
| I calculated the figure using the accounting approach we selected for this disclosure, and I kept the working papers showing how the method was applied to the underlying activity data. | The assurer will check whether the chosen method matches the stated reporting basis and whether it was applied consistently to all relevant data. | Methodology paper; calculation workbook; emission factor source list; activity data extracts; version history; reviewer comments and approvals. |
| I reviewed whether business changes during the year affected the way the number was built, and I adjusted the calculation basis where those changes would otherwise distort the result. | The assurer will look for evidence that structural changes were identified, assessed and reflected in the calculation rather than ignored. | M&A and restructuring papers; change log; recalculation memo; prior-period comparison analysis; management review evidence. |
| I used the prior fiscal year as the reporting period for the disclosed number and checked that the dates in the supporting files matched that period. | The assurer will test whether the figure relates to the correct year and whether the source data and final disclosure are aligned to that period. | Reporting calendar; period-end data extracts; ledger or operational reports for the year; reconciliation to the disclosed period; sign-off pack. |
| I listed the direct emission sources that fed into the total, and I kept a source inventory that ties each item back to the underlying site or asset. | The assurer will probe completeness of the source list and whether each source can be traced to a real operational basis. | Source inventory; site/asset register; mapping from sources to locations or equipment; inclusion/exclusion rationale; supporting operational records. |

Sintéticos, redactados por LRA: no proceden del informe de ninguna empresa ni del texto de ninguna norma.
We report for our consolidated operations covering 1 January to 31 December 2025, and the figures below relate to the sites and activities we control in that period.
- We used an activity-based approach with emission factors to convert fuel use and other direct sources into tonnes of CO2e.
- Our direct emissions came from gas-fired boilers, company vehicles, and on-site backup generators.
- For this reporting year, our total direct greenhouse gas emissions were 18,400 tCO2e.
This example shows a first-person narrative disclosure that identifies the reporting year, explains the boundary in plain terms, names the main direct sources, and states the calculation approach and total.
Our disclosure covers the full year from 1 April 2025 to 31 March 2026 and includes the business units and facilities we operate and control.
- We estimated direct emissions using measured fuel consumption and standard conversion factors.
- The main sources were refrigeration leaks, natural gas used in processing, and delivery vans.
- Our total direct greenhouse gas emissions for the period were 9,750 tCO2e.
This example uses different wording and a different sector while still showing the period covered, the organisational boundary, the method used, the direct sources included, and the total direct emissions.

Escenarios para trabajar
A manufacturing group runs one UK site and two overseas depots. The sustainability team has emissions from gas boilers, company vans and backup generators, but the finance team is unsure whether to include a leased warehouse where the group does not control fuel use.
A retailer has calculated direct emissions using fuel purchase records for its fleet and gas meters for its stores. The team also has an estimate for refrigerant leaks, but the working papers do not explain how the estimate was built.
A group reports on a calendar-year basis, but one business unit has prepared direct emissions for its own financial year ending 31 March. The consolidated pack also includes a total for the previous 12 months, but no one has confirmed which period the disclosure should cover.
An industrial company has direct emissions from boilers, owned delivery trucks and a small on-site generator. The draft note gives a total of 18,400 tCO2e, but it does not say which sources were included, and the team is unsure whether to mention all source types or only the largest ones.

Preguntas frecuentes
Preguntas que responde esta página
Use the page’s plain-language explainer and the datapoints to prepare as your starting checklist: boundary for emissions, calculation approach, reporting timeframe, emission activity sources, and the direct emissions total. The step-by-step preparation section then helps you turn those inputs into a draft.
The page tells you to prepare a boundary for emissions, so the practical task is to define what is in scope before you calculate or write up the disclosure. Keep the boundary decision documented in your evidence pack so the draft can be checked later.
The page asks you to prepare a calculation approach, so you should record the method you used and keep it consistent with the rest of the data you are reporting. The assurance section and evidence pack are there to help you show how the figure was built.
The page says to prepare the reporting timeframe, so make sure the period covered by the disclosure is explicit in your draft and supporting files. That helps the reviewer see which data set the direct emissions total relates to.
The page is useful for assigning ownership because it separates the data points, the assurance checks, and the evidence pack. In practice, that lets a sustainability lead, data owner, or reviewer see who is responsible for each part of the draft.
The page includes an evidence pack with five items for assurance readiness, so you should use that as the core file set behind the disclosure. It also lists six assurance claims to verify, which helps you match each claim to supporting evidence.
The page has a section on common reporting gaps and mistakes, so use that before finalising the draft to check for missing scope, unclear methods, or incomplete support. It is meant to help you catch avoidable issues early rather than after review.
The Download Centre includes a Prep & Assurance workbook in .xlsx format, which is designed to help you organise the preparation and assurance steps. Use it alongside the printable Library Card if you want a quick reference while drafting or reviewing.
The page includes synthetic illustrative example disclosures, including a quantitative table, so you can see how the information may be presented in practice. Treat the example as a drafting aid only and make sure your own figures and scope are internally consistent.
The page says the closest ESRS correspondence is ESRS E1 (Climate Change), so the data may be reusable across both contexts. It does not say the requirements are identical, so you still need to check the other framework separately.
The page has a draft-output section with visualisation ideas, narrative starters, and a content-index line, which you can use to shape the final write-up. That makes it easier to move from collected data to a clear draft for review.
