To prepare this disclosure
Disclosure focus

This disclosure asks an organisation to report how much greenhouse gas it emits relative to a chosen measure of activity, rather than only giving a total emissions figure. The point is to show the relationship between emissions and what the organisation actually does, so readers can understand efficiency or carbon performance in context.

In practice, the main focus is on using a clear, consistent intensity metric and explaining what it covers. The organisation should be clear about whether the figure reflects all operations or only part of the business, and whether it includes just flagship sites, selected facilities, or the full operational footprint, so the result is not misleading.

This LRA educational guidance supports disclosure preparation. For the exact requirements, always refer to the official GRI source.

Before you start

A quick mental checklist before you prepare this disclosure — tick each as you settle it.

Preparation

Key information to prepare

Preparation field What to capture Evidence hint Owner
Emissions intensity value Capture the calculated emissions intensity figure, with the underlying gross greenhouse gas emissions amount and the activity, revenue, output or other denominator used to form the ratio, so the percentage can be traced back to the source calculation. Calculation workbook, emissions inventory extract, and the source dataset for the chosen denominator. Sustainability reporting / ESG data owner with Finance support
Included emissions scopes Record which greenhouse gas emissions scopes are included in each intensity ratio, using the same scope boundary as the calculation and making clear whether the ratio covers one scope or a combination of scopes. Methodology note, emissions boundary schedule, and the calculation file showing the scope selection used for the ratio. Sustainability reporting / ESG data owner

How to prepare it

1Decide the reporting boundary first: confirm which greenhouse-gas scopes will be included in the intensity measure, and make that choice explicit before you calculate anything.
2Set the definition of the ratio clearly: identify the emissions figure that will sit behind the intensity result, and keep the same basis throughout the calculation.
3Gather the supporting records: pull together the source data that shows the emissions amount used in the ratio, along with the material needed to evidence the scope choice.
4Calculate and present the figures: prepare the intensity ratio(s) and the underlying gross emissions amount in the format required for reporting, making sure the numbers reconcile to the evidence.
5Record any limits or changes: note any exclusions, boundary decisions, or changes in approach so a reviewer can see how the reported result was built.
6Check the final disclosure against the official source: verify that the reported ratio, the emissions basis, and the scope statement match the source material before sign-off.
Request the data

Request the emissions intensity data

Translate the disclosure into an internal business question — then adapt it to your organisation's own language.

What emissions intensity figures should we report, and which emissions scopes are included in each figure?

Please use your organisation’s own terms first (for example, your internal names for emissions metrics, reporting periods, business units and source systems), then map them to the disclosure fields below. This is a possible LRA training template only; adapt it to your organisation and check the official source before sign-off.

Weak request

Please provide the GHG emissions intensity disclosure data for the reporting period.

Why it fails: This uses framework language, does not say which internal metric is needed, and leaves out the gross emissions amount, the scopes included, the calculation basis, and the source record needed to verify the figure.

Better request

Please send the emissions intensity figures your team uses for [reporting period] for [entity / business area], together with the gross emissions amount behind each figure, the scopes included, the denominator used, the formula, and the source file or system extract.

Formal email template
Subject: Request for emissions intensity data for [reporting period]

Assurance readiness

For each claim, check the evidence

ClaimRiskEvidence to check
We used the same basis for the coverage figure as in our underlying records, and we can show how the number was built from source data.The assurer will check whether the figure was assembled consistently from the underlying records, rather than adjusted ad hoc or taken from an unsupported summary.Source datasets, calculation workbook, methodology note, version history, and sign-off showing the final figure ties back to the underlying records.
We defined the included operations before we calculated the figure, and we can explain any entities, sites, or activities left out.The assurer will probe whether the scope choice was made consistently and whether exclusions could materially change the disclosed figure.Scope memo, boundary decisions, organisational charts or entity lists, inclusion/exclusion rationale, and any approvals for the final coverage basis.
We relied on data that had been checked before publication, and we can evidence the controls used to spot errors or gaps.The assurer will look for weak data quality controls, missing checks, or unresolved anomalies in the figures used for disclosure.Data validation logs, reconciliations, exception reports, review notes, and evidence of corrections made before release.
We kept support for the disclosed figure, including the working papers and the records behind it, so the calculation can be traced end to end.The assurer will test whether there is a clear audit trail from the published number back to the source information and assumptions used.Working papers, source extracts, calculation files, supporting documents, and a clear trail from inputs to the published figure.
Before publication, we carried out internal checks on the final version and obtained the relevant review sign-off.The assurer will assess whether the final disclosure was reviewed by the right people and whether any issues were cleared before release.Pre-publication review checklist, approval emails or workflow records, final draft with tracked changes, and evidence that identified issues were resolved.

Evidence pack to prepare

Common reporting gaps

A percentage is stated without the underlying counts (numerator and denominator).The denominator — what the figure is a share of — is not explained.Partial scope is reported as if it were complete coverage.One-off activities are counted as if they were ongoing programmes.Boundary or period changes that move the figure are not flagged.Exclusions from the reported scope are not listed or explained.
Common gaps

Mistakes to avoid when collecting the data

Wrong owner asked
The team chases the sustainability lead for numbers that sit with finance, operations, or the emissions inventory owner, so the data never comes from the person who actually holds the source records.
Framework terms used too early
People ask for the ratio in disclosure language instead of the business metric the organisation already tracks, which leaves the data owner unsure what to pull from their systems.
Boundary not pinned down
The collector does not agree which parts of the business sit inside the calculation, so site, subsidiary, or activity data get mixed without a clear cut-off.
+ Show 5 more

Where judgement is often needed

Set the group boundary after acquisitions or disposals
Decide whether the intensity figure uses the business mix at period end or a like-for-like base, then explain any restatement or exclusion so readers can see how bought-in or sold-off operations affected the result.
Choose one emissions scope mix and keep it clear
If the ratio covers only some emissions streams, state exactly which ones are in and which are out, and explain the basis for that split in plain operational terms.
Handle mixed country methods with a single stated approach
Where sites in different countries use different local calculation rules or activity data, pick one organisation-wide method or explain the country-by-country differences and how they were brought onto a common basis.

Examples

Illustrative examples

Synthetic, written by LRA — not from a company report, not text from any standard.

Illustrative (synthetic) example — food processing

We report a greenhouse gas intensity figure based on our total direct and indirect emissions, shown against a business output measure. The ratio uses Scope 1 and Scope 2 emissions only, and this synthetic example is for illustration only.

This example shows how to present an emissions intensity metric by pairing the total emissions used in the ratio with the scopes included in that calculation.

MeasureScope 1Scope 2
Emissions used in the ratio (tCO2e)120008000
Share of emissions used (%)6040
Intensity basis (tCO2e per £m revenue)0.40.27
Illustrative (synthetic) example — logistics

We present an emissions intensity figure using our total greenhouse gas output and the scopes included in that calculation. In this synthetic example, the ratio is based on Scope 1, Scope 2 and Scope 3 emissions, and it is illustrative only.

This example shows a broader intensity calculation that includes all three emissions scopes, with the emissions total and the scope split shown consistently.

Examples of full and partial reporting practice. These are evidence-led reviews, not exact disclosure templates to copy.

Kasikornbank Public Company Limited
Banks / Diverse Financials / Insurance · Thailand · 2025
Open report →
Kasikornbank Public Company Limited’s 2025 Sustainability Report provides coverage of its Scope 1 greenhouse gas (GHG) emissions calculation, noting it is based on fuel use (p.78), and includes narrative information on Scope 1, 2, and 3 emissions by asset (p.61). The report references detailed Scope 2 and Scope 3 emissions data in other sections (p.86), indicating some level of disclosure on these categories. However, the exact percentage values for emissions intensity and comprehensive quantitative data for Scope 2 and 3 emissions are not clearly presented in the provided excerpts, leaving some details unclear.
Thai Beverage Public Company Limited
Food and Beverage Processing · Thailand · 2024
Open report →
Thai Beverage Public Company Limited’s Sustainability Report 2024 provides detailed quantitative data on greenhouse gas (GHG) emissions, including Scope 1 and Scope 2 emissions in tonnes of CO2e, with figures reported on page 172. The report also references Scope 3 emissions and outlines a target to reduce GHG emissions by 42% by 2030, covering both direct and indirect emissions (p.31, p.37, p.172, p.184). However, the report lacks a narrative explanation or qualitative discussion of these emissions or reduction strategies, as no such content was found.
SCB X Public Company Limited
Banks / Diverse Financials / Insurance · Thailand · 2024
Open report →
SCB X Public Company Limited’s 2024 Sustainability Report provides specific data on Scope 1 greenhouse gas emissions, reporting values such as 8,039 and 7,514 tonnes CO2e on page 113. The report also highlights a 15% reduction in Scope 1-2 emissions and non-hazardous waste, as noted on page 10. However, while there are references to broader GHG reduction targets and net zero goals on pages 77, 78, and 80, detailed quantitative data for Scope 2 emissions and comprehensive emissions intensity metrics are less clearly presented or missing.

Scenarios to work through

A manufacturing group has calculated one emissions-per-output ratio for the year, but the draft note only shows the ratio and leaves out the underlying emissions figure used to build it. The team also used a mix of direct and purchased-energy emissions, but that is not yet stated.

QWhat should the preparer do before sign-off so the note is usable and complete?
Reveal model answer →

A services business reports two intensity measures: one based on total emissions and revenue, and another based on emissions from its own operations only. The draft wording says only that the business has an intensity measure, without explaining which emissions boundary applies to each ratio.

QHow should the preparer handle the scope information for these ratios?
Reveal model answer →

A retailer has a single intensity ratio for the year and the calculation is correct, but the supporting schedule shows the emissions total in tonnes while the disclosure draft labels the ratio as a percentage without showing the emissions figure alongside it. The reviewer is unsure whether the note is complete enough.

QWhat is the key check the preparer should make on the presentation of the data point?
Reveal model answer →

A group prepares its sustainability note using a template from a prior year. The old version listed the ratio but did not say whether the calculation covered only direct emissions or also other emissions sources, and the team is tempted to reuse it unchanged because the number itself has not changed.

QWhat should the preparer verify before carrying the template forward?
Reveal model answer →
