To prepare this disclosure
Disclosure focus

This disclosure asks an organisation to explain how much greenhouse gas it emits relative to a chosen measure of activity, so readers can understand emissions efficiency rather than just total emissions. The key point is to show the intensity metric used, the basis for it, and the result in a way that is clear and comparable within the organisation’s own reporting approach.

In practice, the focus is usually on whether the intensity measure covers the organisation’s full operations or only selected parts, and on making the boundary and calculation basis explicit. If the organisation uses different intensity measures for different activities, it should be clear what each one relates to and why that measure is the most meaningful way to present performance.

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

How to prepare it

1Set the reporting boundary first: decide which parts of the business are in scope for this intensity measure, so the calculation is built on one clear organisational perimeter.
2Choose the activity yardstick you will divide by, and record it in business terms that fit your organisation; this is the denominator used to express the intensity figure.
3Define the emissions content of the calculation before you start compiling numbers: state which emission categories are included, and which gases are counted in the total.
4Gather the supporting records for both sides of the ratio: the emissions data, the chosen activity measure, and the working papers that show how each figure was derived.
5Assemble the disclosure in the required format, including the intensity number itself, its unit, the denominator description, and the lists of included emission types and gases.
6Note any exclusions, scope changes, or judgement calls made in the calculation, then check the final disclosure against the official source to confirm the wording, scope, and figures still align.
Request the data

Request the emissions intensity data from Operations

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

What emissions intensity figure should we use for this reporting period, and what calculation basis, gases, and emissions scope sit behind it?

Use your organisation’s own terms first, then map them to the reporting disclosure. For example, ask for the metric your teams already track, the emissions set they use, and the gases included, rather than using framework labels in the first ask. Check the official source before sign-off.

Weak request

Please send the GHG emissions intensity ratio and the gases and emissions types included.

Why it fails: This uses framework language without telling the owner what internal metric, boundary, source file, or calculation basis to provide. It is too abstract to action quickly and may lead to an incomplete response.

Better request

Please send the latest emissions intensity calculation for [period], including the business metric used as the denominator, the emissions set included, the gases included, the boundary covered, the source workbook or system, and the supporting evidence link. Use your team’s own terms first, then we will map them for reporting.

Draft your disclosure

Notes that turn data into a disclosure

LRA training templates — adapt them to your organisation, and check the official source before sign-off.

Method note

State the business measure used as the divisor, the gases and emission sources counted in the calculation, and the unit used to present the final intensity figure.

Context note

Explain what the intensity figure says about emissions relative to the chosen business measure, so readers can understand the scale of emissions against activity or output.

Fluctuation statement

If the ratio changes materially, note whether the movement came from changes in emissions, changes in the chosen business measure, or both.

Assurance readiness

For each claim, check the evidence

ClaimRiskEvidence to check
We have shown how the coverage figure was calculated and which parts of the business were included in that calculation.An assurer will check whether the figure is based on the same organisational boundary and reporting period used elsewhere, and whether any exclusions were deliberate, consistent and explained.Boundary memo; reporting scope paper; consolidation approach; calculation workbook; list of included entities/sites; explanation of any exclusions; sign-off notes.
We have stated the unit used for the coverage figure and used it consistently in the published table.An assurer will probe whether the unit is clearly defined, applied without mixing measures, and matches the underlying calculation and presentation.Draft and final disclosure; calculation model; unit definition note; spreadsheet formulas; review checklist showing the unit was checked before publication.
We selected a business-specific denominator that reflects how the organisation operates and can be traced back to source data.An assurer will test whether the chosen denominator is appropriate for the business, consistently applied, and supported by reliable source records rather than a convenient proxy.Methodology note explaining the denominator choice; source data extracts; management approval; prior-period comparison; evidence of consistency with internal reporting.
We identified which emissions streams were counted in the ratio and kept the inclusion approach consistent with the rest of the report.An assurer will look for clarity on what was included and excluded, whether the same inclusion logic was used throughout, and whether the disclosed figure could be materially affected by omitted streams.Calculation methodology; emissions inventory mapping; inclusion/exclusion schedule; reconciliation to the wider emissions dataset; review comments and resolution log.
We set out which greenhouse gases were used in the calculation and retained support for that selection.An assurer will check whether the gas list is complete for the chosen method, whether any gases were left out without explanation, and whether the calculation files match the published statement.Calculation workbook; emissions factor library; methodology paper; source inventory; technical review sign-off; evidence of checks against the published wording.

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 the denominator and source files, when the real figures sit with finance, operations, or the business unit that runs the activity.
Framework language used too early
People ask for the data using disclosure terms instead of the organisation’s own labels, so the owner cannot map the request to a live report, system field, or KPI.
Boundary left vague
No one pins down which parts of the business, sites, or activities are in scope, so different teams pull different populations and the ratio is built from mismatched inputs.
Wrong period basis
The numerator and denominator are taken from different reporting periods or cut-off dates, which makes the intensity figure combine data that was never measured on the same timing basis.
Counting basis mixed up
One source is collected on a gross basis and another on a net or adjusted basis, so the final ratio blends unlike methods and cannot be traced back cleanly.
Source labels stripped out
During consolidation, the original file names, system tags, and local column headings are removed, leaving no clear link back to the first record or extract.
Populations merged that should stay apart
Separate business lines, sites, or product groups are rolled into one pool even though they need distinct treatment, which hides differences in the underlying intensity drivers.
Evidence trail incomplete
The dataset is saved without the supporting notes, version history, and reviewer sign-off, so nobody can show who checked it, when it was checked, or what changed.

Where judgement is often needed

Set the business boundary after a buy-in or sale
Use one clear cut-off for which sites, teams and activities sit in the ratio, then explain any change in coverage caused by an acquisition, disposal or similar move.
Choose one country rule when local definitions differ
If the same activity is described differently across jurisdictions, pick the definition you use for the ratio, apply it consistently, and note where local reporting practice differs.
Decide how to treat borderline operations
For assets, ventures or activities that sit near your reporting boundary, state whether they are in or out of the calculation and explain the basis for that call.
Fix the timing basis for the numerator and denominator
State whether the emissions figure and the business measure come from the same period or from a different timing basis, and explain any mismatch.
State where estimates replace direct readings
If some emissions data are modelled, extrapolated or otherwise estimated, identify the parts affected and explain the method used instead of direct measurement.
Explain the metric used to scale emissions
Name the organisation-specific measure used to divide emissions, describe how it is defined, and make clear if it differs by business line, country or period.
Be clear about which gases are counted
List the gases included in the calculation in plain business terms and explain any exclusions so readers can see what sits behind the ratio.
Show how rounding affects the published figure
If rounding changes the displayed result, say what rounding rule you used and keep the underlying calculation traceable in working papers.
Aggregate enough to protect personal or sensitive data
Where the denominator or activity data could expose confidential information, combine figures to a level that protects privacy and explain the aggregation approach.
Examples

Illustrative examples

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

Illustrative (synthetic) example — manufacturing

We report a synthetic emissions-efficiency figure by dividing our total greenhouse gas output by tonnes of product shipped. The ratio is shown using all direct and indirect emissions we include in our inventory, and the gases counted are carbon dioxide, methane and nitrous oxide.

Illustrative only: the figures below are internally consistent and show how a company might present an emissions-efficiency ratio with its chosen business measure, the emissions scope used, and the gases included.

Illustrative (synthetic) example — retail

We present a synthetic emissions-intensity figure based on our annual sales revenue. The calculation uses the emissions streams we include in our footprint, and the gases counted are carbon dioxide, methane, nitrous oxide and fluorinated gases.

Illustrative only: the figures below are internally consistent and show how a retailer might present an emissions-intensity ratio with its chosen business measure, the emissions scope used, and the gases included.

Scenarios to work through

A manufacturing group has calculated one emissions intensity figure for the year using tonnes of product output as the denominator. The draft note also mentions that the ratio is based on carbon dioxide, methane and nitrous oxide, but it does not say which emissions scopes were included.

QWhat should the preparer check before sign-off so the intensity disclosure is complete?
Reveal model answer →

A services company has prepared an intensity metric using revenue as the denominator. The draft says the result is 0.42, but it does not show whether that figure is expressed in tonnes of carbon dioxide equivalent or another unit.

QHow should the preparer decide whether the presentation is ready?
Reveal model answer →

A logistics business has two possible ways to present its intensity: emissions per tonne-kilometre and emissions per delivery. The team has not yet agreed which measure best reflects the business model, and the draft currently includes both.

QWhat is the right judgement to make about the denominator before reporting?
Reveal model answer →

An energy company has calculated its intensity using only carbon dioxide and methane from operational emissions. The draft note does not say whether other greenhouse gases or other emissions categories were left out on purpose.

QWhat should the preparer do to make the disclosure understandable?
