Foco de la divulgación

This disclosure asks an organisation to report the greenhouse gas emissions linked to the electricity, steam, heating or cooling it uses, rather than emissions it creates directly on site. In practice, the focus is on the emissions associated with purchased energy across the organisation’s reporting boundary, so the organisation needs to identify where it uses energy and quantify the related indirect emissions in a consistent way.

The practical question is coverage: the report should reflect the organisation’s full operations that fall within scope, not just a few prominent locations or flagship sites. That means checking all relevant facilities, offices, warehouses, plants and other operations that consume purchased energy, so the reported figure is not limited to selected examples but represents the organisation’s overall footprint for this emissions source.

Cómo prepararlo

Set the boundary for this disclosure first: identify the electricity, steam, heating, and cooling you bought or otherwise obtained, and confirm which of those purchases sit within the reporting year you are using.
Gather the source records that support those energy purchases, then use them to build the emissions figures for the same period in two ways: one based on the grid or local supply mix, and one based on the contractual or supplier-specific view you use internally.
Calculate the overall amount for the period, making sure it reconciles to the two emissions views and to the underlying energy data you have collected.
Keep a clear audit trail for any items you leave out, any estimation choices, and any changes to methods, data sources, or assumptions compared with the prior cycle or earlier drafts.
Prepare the final disclosure package with the reporting period, the total emissions figure, and both emissions views in the required unit, supported by the evidence you assembled.
Before submission, check your draft against the official source and confirm that the scope, figures, labels, exclusions, and method notes still match the current requirement.

Solicitar los datos

Request the electricity and heating data

Traduzca la divulgación a una pregunta de negocio interna y adáptela después al lenguaje propio de su organización.

What energy we bought or used for the reporting period, and what that means for our Scope 2 emissions figures?

Use your organisation’s own names for sites, utilities, meters, invoices, and reporting packs first, then map them to the fields below. This is a possible LRA training template only; adapt it to your organisation and check the source material before sign-off.

Solicitud débil

Please provide Scope 2 data, including location-based and market-based emissions, for the reporting period, with evidence.

Por qué falla: It uses framework language that many operational teams will not use day to day, and it does not tell the owner which utility records, site data, calculation basis, or source files to pull together. It is also too vague about the period, the systems, and the evidence needed to support the figures.

Solicitud mejor

Please send the energy and emissions pack for [reporting period] for [sites/business units]. Include the electricity, steam, heat, and cooling we bought or used, the emissions figures in tCO2e using both calculation approaches where available, the source files or invoices, the period covered, and any assumptions, estimates, or gaps. Use your normal site and utility names, then we will map them to the reporting fields.

Preparación para el aseguramiento

Para cada afirmación, compruebe la evidencia

Afirmación Riesgos Evidencia que comprobar
We built the coverage figure from utility and supplier records for the energy we bought or used, and we checked that the boundary was set to capture those indirect emissions wherever the activity occurred.The assurer will test whether the boundary was applied consistently and whether any purchased energy streams were left out or double-counted.Boundary memo; list of included energy sources and sites; utility invoices and supplier statements; consolidation or mapping schedule showing how locations were captured; review notes confirming no exclusions without justification.
We prepared the emissions numbers using the same calculation approach and guidance set used across the rest of our greenhouse gas reporting, and we kept the working papers that show that approach was followed.The assurer will probe whether the figures were calculated on a consistent basis and whether the team can demonstrate alignment with the chosen reporting method.Calculation methodology document; version-controlled spreadsheets or system outputs; references used by the preparer; internal methodology sign-off; evidence of any updates and why they were made.
For the location-based figure, we used the grid or local supply data tied to the places where the energy was consumed, then converted the result into tonnes of carbon dioxide equivalent for disclosure.The assurer will check whether the location-based number reflects the right consumption data, the right emission factors, and the correct unit conversion.Consumption data by site; emission factor source files; calculation workbook; unit conversion checks; reconciliation from site-level inputs to the disclosed total.
For the market-based figure, we used the contractual and supplier information we held for the period, and we retained the evidence showing how those instruments or claims were applied in the calculation.The assurer will test whether the market-based result is supported by valid contractual evidence and whether the treatment of supplier-specific information is consistent and complete.Contracts, certificates, tariffs or other supplier documents; register of instruments used; calculation workbook; checks on validity dates and coverage; evidence of review for overlaps or gaps.
We reported the prior financial year as the period covered, and we checked that the disclosed total ties back to the underlying working papers before publication.The assurer will look for a clear reporting period, a complete roll-up to the total, and evidence that the final number was reviewed before release.Reporting calendar; period-end cut-off note; final consolidation file; tie-out from source data to disclosed total; approval or sign-off record; publication checklist.

Paquete de evidencia que preparar

Carencias habituales en los informes

Figures are stated without the supporting narrative, or narrative without figures.
Scope is inconsistent between the text and the numbers.
The reporting boundary is left undefined.
Material changes since the previous period are not disclosed.
Estimates and measured values are not distinguished.
Source records for the figures are not identified.

Carencias habituales

Errores que evitar al recopilar los datos

Wrong owner, wrong inboxThe request goes to a generic sustainability contact instead of the team that actually holds electricity and utility records, so the data never reaches the person who can verify it.
Using framework language too earlyThe ask is framed in reporting jargon rather than the organisation’s own utility and energy terms, so the recipient cannot tell which internal records are needed.
No clear boundary for what is in scopeThe collector does not define which sites, entities, or energy bills belong in the dataset, so some relevant usage is left out while unrelated items are pulled in.

Dónde suele hacer falta juicio profesional

Set the reporting boundary after a buy, sale, or reorganisationDecide whether the year covers the business as it stood before or after the change, explain the cut-off used, and keep the same approach across the period unless a change is clearly described.
Handle country-by-country electricity labels with one internal ruleWhere local utility or contract labels differ, map them to a single internal method for purchased power and explain the mapping so the same site is treated consistently across locations.
Decide how to treat sites or activities near the boundaryFor shared buildings, leased spaces, joint ventures, or other borderline cases, state the inclusion rule you used and explain any exclusions or partial inclusions.

Illustrative (synthetic) example — manufacturing

During our 2025 reporting year, we recorded the electricity and other energy services we bought for our sites, including purchased power and district heating/cooling. For that period, our combined indirect emissions were 18,400 tCO2e on a location basis and 16,900 tCO2e using our supplier- and contract-based approach.
- Reporting period: 1 January 2025 to 31 December 2025
- Energy bought: 124,000 MWh of electricity, plus 8,500 MWh of steam and 3,200 MWh of cooling
- Indirect emissions total: 18,400 tCO2e location-based; 16,900 tCO2e market-based

This is a synthetic, illustrative narrative showing the period covered, the energy services purchased, and both ways of presenting indirect emissions from that energy use.

Illustrative (synthetic) example — retail

For our 2025 reporting year, we tracked the power and thermal energy we procured for stores, warehouses, and offices. Our indirect emissions from that energy were 9,600 tCO2e on a grid-average basis and 8,750 tCO2e on a contract-adjusted basis.
- Reporting period: 1 April 2025 to 31 March 2026
- Energy bought: 62,000 MWh of electricity, 1,400 MWh of heat, and 900 MWh of cooling
- Indirect emissions total: 9,600 tCO2e grid-average; 8,750 tCO2e contract-adjusted

This is a synthetic, illustrative example for a different type of reporter, showing the same core data points in plain language.

Escenarios para trabajar

A group leases two offices and a small warehouse. It buys grid electricity for all three sites, plus district cooling for one office, and the finance team has separate figures for a location-based calculation and a supplier-contract-based calculation for the same reporting year.

PShould the disclosure cover those purchased energy types, and should both calculation views be kept for the same period?
Mostrar la respuesta modelo →

A preparer has a year-end total for bought electricity and steam, but the warehouse team also has a separate estimate for chilled water used in the same period. The draft note currently shows only one combined emissions figure.

PWhat should the preparer do before sign-off if the energy list is incomplete?
Mostrar la respuesta modelo →

A company’s market-based figure is lower than its location-based figure because it has supplier arrangements for part of its electricity. The sustainability team wants to report only the lower number because it looks cleaner.

PCan the preparer choose just one of the two figures for the disclosure?
Mostrar la respuesta modelo →

A preparer has the emissions totals ready, but the supporting file names show one quarter from the prior year and three quarters from the current year. The team argues that the annual total is still close enough to use.

PIs it acceptable to mix periods if the annual total seems reasonable?
