Foco de la divulgación
This disclosure asks an organisation to explain whether it uses an internal carbon price in decision-making, and if so, how that price is applied in practice. The focus is on the organisation’s own approach: what the price is used for, how it influences planning or investment choices, and whether it is a formal part of internal processes rather than an informal estimate.
In practical terms, the key question is how broadly the carbon price is used across the business. Reporting should make clear whether it applies only to selected projects, business units or flagship sites, or whether it is embedded across operations and capital allocation more widely. The aim is to show the extent of coverage and how consistently the price is used in real decisions.

Request the internal carbon price details
Traduzca la divulgación a una pregunta de negocio interna y adáptela después al lenguaje propio de su organización.
How do we use an internal carbon price in planning and decision-making, and what evidence shows the price levels, scope, assumptions, and the choices it has influenced?
Use your organisation’s own terms first, then map them to the disclosure. For example, if your team talks about a carbon charge, planning price, or emissions cost assumption, use that language in the request and only translate it afterwards for reporting. This is a possible LRA training template; adapt it to your organisation and check the official source before sign-off.
Solicitud débil
Please provide the internal carbon pricing disclosure and all mandatory evidence for the standard.
Por qué falla: It uses framework language instead of the organisation’s own terms, does not tell the owner what practical information is needed, and does not separate the price level, scope, assumptions, and decision use into clear items that can be evidenced.
Solicitud mejor
Please send the carbon cost assumption or internal charge used in [business area] for [reporting period], including the level(s), where it is applied, how it was set, and the decisions it has influenced. Use your team’s own wording and attach the workbook, policy note, or approval paper that shows how it is used.

Versión corta para Teams / Slack
Hi [name/team] — could you share the internal carbon price details for [reporting period] in [business area]? We need the price level(s), where it is used, the basis/assumptions, and what decisions it has affected. Please send your team’s own wording plus any supporting file/link. Thanks.
Ejemplos sectoriales
Manufacturing
Contexto. A group uses a carbon cost in capex screening and plant upgrade cases.
Solicitud adaptada. Hi [name/team], please share the carbon cost assumption used in capex appraisals for [reporting period]. We need the level(s), which projects it applies to, the basis for setting it, and any examples of investment decisions it changed. Please include the model or approval note.
Ejemplo de respuesta. The planning team uses a carbon cost of £75 per tCO2e for all major capex cases above £1m. It is applied in the investment model and was used in three plant upgrade approvals. The level was set by Finance and Sustainability based on the medium-term transition plan.
Financial services
Contexto. A bank uses an emissions cost assumption in lending and portfolio planning.
Solicitud adaptada. Hi [name/team], could you send the emissions cost assumption used in portfolio planning for [reporting period]? Please include the level(s), the products or portfolios it covers, the basis for the assumption, and the decisions it has influenced. A policy note or committee paper would be helpful.
Ejemplo de respuesta. The risk team applies a carbon cost of £120 per tCO2e in transition scenario work for corporate lending portfolios. It covers sectors flagged as higher exposure in the climate model. The assumption informed sector limits and client engagement priorities, as set out in the committee paper.

Preparación para el aseguramiento
Para cada afirmación, compruebe la evidencia
| Afirmación | Riesgos | Evidencia que comprobar |
|---|---|---|
| We have explained where the figure is used in our planning and appraisal process, and which business choices it feeds into. | An assurer may ask whether the stated use is real, current, and supported by documented decision processes rather than a generic policy statement. | Internal policy or methodology note; examples of investment, budgeting, pricing, or project papers showing the figure being used; approval papers or meeting packs that reference the figure. |
| We have set out the parts of the business the figure covers, together with the main assumptions we used to apply it. | An assurer may probe whether the coverage is complete for the stated boundary and whether the assumptions are consistent, reasonable, and applied in the same way across the reporting period. | Boundary memo; calculation workbook; assumption log; source data extracts; reconciliation between covered activities and the reported figure; version history showing assumption changes. |
| We have identified the decisions that were actually shaped by the figure, rather than only describing intended future use. | An assurer may challenge whether the examples are specific, evidenced, and attributable to the figure, or whether they are merely illustrative. | Decision papers, capex requests, procurement cases, strategy papers, or board/committee packs showing the figure influencing a choice; sign-off notes; links between the figure and the final decision. |
| We have stated the price level we used for each relevant calculation, and the amounts are consistent with the underlying working papers. | An assurer may test whether the stated level matches the calculations, whether units are clear, and whether any different rates were applied without explanation. | Calculation schedules; model outputs; unit conventions; source files showing the rate applied; review notes confirming the published amount matches the working papers. |
| We have made clear whether we used a notional planning price, an internal charge, or a levy-style mechanism, and we can show how that mechanism operates in practice. | An assurer may ask whether the mechanism is described accurately and consistently, and whether the label used in the report matches the way the organisation actually applies it. | Methodology paper describing the mechanism; finance or treasury procedures; internal charging or transfer pricing documents; examples of postings or allocations; governance approval for the mechanism. |

Ejemplos ilustrativos
Sintéticos, redactados por LRA: no proceden del informe de ninguna empresa ni del texto de ninguna norma.
*Illustrative only: our group uses an internal carbon charge to steer capital spending and operating choices.* We apply a shadow carbon price of **£85 per tonne of CO2e** to **100%** of new project appraisals, while a separate internal levy of **£40 per tonne of CO2e** is used for **60%** of business-unit budgets; the levy covers **12 of 20** units, and **6 of those 12** also use the shadow price in local planning. The price signals have influenced **14 investment decisions** this year, including **9 equipment upgrades**, **3 logistics changes** and **2 product-design changes**; the remaining **6 decisions** were informed by the same pricing approach but did not change the final option selected.
This synthetic example shows how a reporter can explain where carbon pricing is used, what level is applied, how much of the business it reaches, and which choices it has affected, while distinguishing a planning price from an internal charge.
*Illustrative only: our company uses carbon pricing in procurement and store operations to shape day-to-day decisions.* We apply a shadow price of **£70 per tonne of CO2e** to **80%** of supplier tenders and a separate internal fee of **£25 per tonne of CO2e** to **100%** of store energy plans; the shadow price covers **16 of 20** tenders, and the fee covers **240 of 240** stores. During the year, the pricing approach affected **11 decisions** in total: **7 supplier selections**, **2 refrigeration replacements** and **2 store-opening plans**.
This synthetic example demonstrates a second plausible pattern: one price used for external sourcing decisions and another for operational planning, with clear coverage and a short list of decisions that were changed or shaped by the pricing signal.

Escenarios para trabajar
A group finance team uses a notional carbon price in project appraisal for two business units, but one smaller unit still relies on a separate internal charge for emissions. The reporting pack also shows that the price is applied only to capital projects above a set threshold.
An energy company applies a carbon assumption only to new investment cases in one division, while the rest of the group uses no carbon price at all. The draft note says the price is used across the whole business, which is not accurate.
A manufacturer uses a carbon price in capital allocation, procurement screening, and product design choices. The draft disclosure mentions the price level but leaves out the decisions it actually shaped, even though the investment committee relied on it in several cases.
A utility group uses two different carbon values: one is a planning assumption for long-term projects, and the other is an internal levy collected from operating units. The draft note lists both numbers but does not explain which is a planning value and which is a charge passed through the business.

Preguntas frecuentes
Preguntas que responde esta página
Start with the plain-language explainer, then work through the page’s step-by-step preparation section and the listed datapoints: carbon price uses, scope and assumptions, affected decisions, price level, and internal charge method. The page is designed to help you turn those inputs into a draft disclosure and an evidence pack.
The page says to prepare five datapoints: carbon price uses, scope and assumptions, affected decisions, price level, and internal charge method. Use those as your minimum data checklist before drafting.
The page is aimed at sustainability/ESG managers, HR or data owners, and assurance reviewers, so ownership should sit with the person who can explain the data, the method, and the evidence behind it. The workbook and evidence-pack sections are there to help you assign and document that ownership.
The page includes an evidence pack with five items for assurance readiness, alongside five assurance claims to verify. Use those materials together so you can show the claim, the risk, and the supporting evidence in a clear trail.
The page says there are five assurance claims to verify, each linked to a claim, risk, and evidence view. Use that section to test whether your draft is supported and whether the evidence pack is complete.
The page lists common reporting gaps and mistakes, so it is useful as a pre-submission check. Review those gaps against your draft to catch missing scope, weak assumptions, or unsupported statements before sign-off.
The Download Centre includes a Prep & Assurance workbook in .xlsx format, which is meant to support preparation and assurance readiness. Use it to organise the datapoints, evidence, and draft content before you finalise the disclosure.
The Download Centre also includes a printable Library Card in .pdf format. It is a practical companion for working through the page’s guidance, especially if you want a quick reference while preparing the disclosure.
Yes, the page includes synthetic illustrative example disclosures, including a quantitative table, which can help you see how the disclosure might look in practice. Treat it as a drafting aid only and make sure your own figures, scope, and wording match your organisation’s data.
The page has a draft-output section with visualisation ideas, narrative starters, and a content-index line. Use those to convert the prepared datapoints into a clear draft and then check it against the evidence pack.
The page notes ESRS E1 (Climate Change) as the closest ESRS correspondence, so it can help you think about reuse of data across frameworks. It does not say the requirements are identical, so use it as a practical cross-check rather than a one-to-one mapping.
