GRI 302-2 — Energy consumption outside of the organization

Disclosure focus

This disclosure asks an organisation to explain how much energy it uses outside its own operations, rather than only within sites it directly controls. In practice, that means looking at energy consumption linked to activities in the value chain or other external arrangements that are relevant to the organisation’s reporting boundary, and describing the amounts in a way that is clear and comparable.

The practical focus is on coverage and completeness: whether the organisation has considered all relevant external energy use, not just a few flagship locations or the easiest-to-measure cases. A useful report should make clear what is included, what is left out, and how the organisation has identified and measured the energy use it reports.

Before you start

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

Have you decided which off-site energy uses sit within your reporting boundary, and which do not?
Are you clear on the time period and basis you will use to compile the figures?
Can each figure be traced back to a source record, model, or working paper?
Have you settled the calculation approach, including any assumptions or tools you will use?
Do you know which conversion factors you will apply, and where those factors came from?

Preparation

Key datapoints to prepare

Datapoint	What to capture	Evidence hint	Owner
External energy use	Capture the energy used beyond the organisation’s own sites or direct control, with a clear description of what is included and how it is measured or estimated.	Utility invoices, supplier statements, metering records, transport or logistics data, and any working papers showing how off-site energy use was compiled.	Sustainability / Energy management
Calculation basis	Record the methods, assumptions, and tools used to turn the underlying activity data into the reported figure, including any rules applied in the calculation.	Method notes, calculation spreadsheets, model outputs, internal guidance, and approval records for the approach used.	Sustainability reporting / Data analytics
Conversion factor source	State where the conversion factors came from, including the issuing body, dataset, version, and date or period used.	Published factor tables, database extracts, supplier documentation, or internal reference lists showing the exact source used.	Sustainability reporting / Data management

How to prepare

Set the reporting boundary first: decide which energy use beyond your own sites and operations will be included, and make that scope clear before you start collecting data.
Agree the definition of what will count in the figure or narrative, so the team uses the same interpretation when identifying relevant off-site energy use.
Gather the supporting records for the selected scope, including the underlying source data and any working papers used to build the disclosure.
Compile the reported figure or written explanation from the evidence, using the same approach consistently across the period covered.
Record any exclusions, changes in approach, or judgement calls, and explain why they were made so the disclosure can be understood in context.
Check the final draft against the official source material to confirm the scope, calculation approach, and conversion-factor source are all reflected accurately.

Request off-site energy use data and calculation notes

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

What energy use linked to our activities happened away from our own sites, and what method and factor sources were used to turn it into the reported figure?

Use your organisation’s own terms first — for example, the labels used by fleet, logistics, travel, facilities, or service teams — then map those terms to the reporting disclosure. Keep the ask in the language people already use internally, and check the source material before sign-off.

Weak request

Please provide the GRI 302-2 evidence for energy consumption outside the organisation, including methodologies and conversion factor sources.

Why it fails: It uses framework language that many operational teams will not recognise, and it does not tell the owner which internal records, labels, systems, or time period to pull from. That makes it harder to answer quickly and increases the chance of an incomplete return.

Better request

Please send the off-site energy use figures for [reporting period] from your usual records for [business area/activity], plus the method, assumptions, calculation tool, and factor source used. If you have separate files for travel, fleet, logistics, or other off-site activity, include those and note any estimates or exclusions.

Assurance readiness

For each claim, check the evidence

Claim	Risk	Evidence to check
We have shown the amount of energy used beyond our own operations, and we can explain how we drew the boundary for that figure.	The assurer may question whether the boundary was set consistently, whether any relevant activity was left out, or whether the figure mixes direct and indirect use without a clear basis.	Boundary notes, calculation workbook, source data extracts, and any internal sign-off showing which activities were included and excluded.
We prepared the figure using documented methods, stated assumptions, and the calculation tools we relied on.	The assurer may probe whether the method was applied consistently, whether assumptions were reasonable and approved, and whether the tool outputs were correctly used.	Method statement, assumption log, tool settings or model files, version history, and review notes showing how the calculation was performed.
We can trace the conversion factors back to their original source and show which set was used for the published number.	The assurer may test whether the factors were current, appropriate to the data, and applied correctly across the calculation.	Source references for the factors, dated copies or links, factor selection records, and evidence of checks confirming the right factors were applied.
The reporting boundary used for this disclosure is documented.	Coverage exclusions or late scope changes are not evidenced.	Boundary memo, entity or site list, and sign-off record.

Common reporting gaps

The information is presented without a date or as-at point.
The scope or boundary of the statement is left undefined.
Key terms are used inconsistently across the report.
Material changes since the previous period are not disclosed.
Assertions are made without supporting detail or a source record.
Boilerplate is used that does not actually answer what is asked.

Mistakes to avoid when collecting the data

Wrong owner
The request goes to the sustainability team by default, even though the usage data sits with fleet, facilities, logistics, or another operational owner.
Framework language only
People ask for the data using disclosure terms instead of the business’s own labels, so the person holding the records cannot tell what to pull.
Scope left vague
No one states which off-site energy uses are in scope, so different teams collect different sets of activity and the final file is not comparable.
Period basis not fixed
The team mixes calendar-year and financial-year records, so the numbers do not line up to one reporting period.
Counting basis mixed
One source is captured as a spend-based estimate while another is recorded from measured activity, and the two are merged without a clear basis check.
Source labels stripped out
The original file names, system tags, or worksheet labels are removed during consolidation, making it hard to trace each figure back to its origin.
Separate groups merged
Data for different off-site energy uses are rolled together even though they should stay apart for review and later disclosure drafting.
Evidence trail missing
The team keeps the numbers but not the supporting notes, assumptions, or sign-off record, so no one can show how the dataset was built.

Where judgement is often needed

Acquisitions and disposals during the year
Set a clear cut-off for bought-in or sold-off operations, then explain whether you included only the period you controlled them and how any partial-year figures were built.
Different country definitions for the same energy use
Where local reporting labels or billing categories differ, map them to one internal rule set and disclose the mapping so readers can see how like-for-like totals were built.
People or sites on the boundary of scope
Decide in advance how to treat shared offices, contractor locations, leased premises, or other borderline cases, and state the inclusion rule you used for each type.
Choosing the time basis for the figures
If your data comes from billing periods, calendar months, or another timing basis, explain the basis used and how you aligned mixed-period records into one reporting view.
Measured data versus estimated data
Use direct readings where available and estimates where not, then disclose the estimation approach, the main assumptions, and which parts of the total were not directly measured.
Conversion factors and calculation tools
State which conversion factors, spreadsheets, systems, or other tools were used, and explain any changes from prior periods so users can understand comparability.
Rounding and small differences in totals
Apply one rounding rule consistently, and note that displayed subtotals may not add exactly to the published total because of rounding.
Protecting sensitive location-level information
If site-level detail could reveal confidential or personal information, aggregate the data to a safer level and explain the level of grouping used.
Mixed sources for the same activity
When one activity is supported by invoices, meter reads, and estimates together, describe the hierarchy you used to combine them and how you avoided double counting.
Changes in the method from one period to the next
If you changed the way you collect, convert, or estimate the figures, say what changed, why it changed, and whether prior-period numbers were restated or left as reported.

Examples

Illustrative examples

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

Food processing · synthetic · written by LRA

Synthetic illustration only. We estimated the electricity and fuel used by contractors and logistics partners while serving our operations, then added those amounts to show the energy linked to activity beyond our own sites.
- The calculation used supplier activity data where available, with spend-based estimates for the remaining cases, and we applied a simple allocation approach for shared transport legs.
- Conversion factors came from the latest UK government emissions and energy conversion tables, with any missing values taken from the relevant fuel supplier documentation.

This example shows how a company might describe energy use tied to activities outside its own premises, together with the methods and factor sources used to build the estimate.

Business services · synthetic · written by LRA

Synthetic illustration only. We compiled the energy associated with outsourced data-centre hosting, leased vehicle use, and other contracted services that support our work but sit beyond our own premises.
- We combined meter readings from service providers with modelled estimates for the gaps, using a location-based approach for electricity and direct fuel records for vehicles.
- The conversion factors were taken from the national government conversion dataset and, where needed, from the service providers' technical schedules.

This example shows a different type of reporter explaining energy linked to external operations, plus the calculation approach and where the conversion factors came from.

From a number to a disclosure

What separates a figure from a disclosure.

Basic

I estimate our energy use outside our own sites at 12,400 MWh.

Better

I estimate that 12,400 MWh of our energy use sits outside our own sites, using supplier data and our internal conversion approach.

Best

I estimate that 12,400 MWh of our energy use sits outside our own sites for the year ended 31 December 2025, using supplier data, our internal conversion approach and published conversion factors; the figure is higher than last year because we added more contracted transport activity.

Evidence in Abertis’s report

What the report shows

Abertis' 2024 Annual Report provides specific data on energy consumption, reporting a 0.6% fuel consumption from renewable sources such as biomass, with quantities detailed as 11,247, 28,755, and 36,868 MWh on page 115. The report also references governance standards and disclosure requirements related to EU legislation on page 214. However, the report does not clearly present comprehensive data on taxonomy alignment or environmental sustainability classifications, as indicated by the 0.0% figures and unclear references on pages 139 and 141.

Check your understanding

A logistics team has fuel data for subcontracted deliveries and wants to include the diesel used by those vehicles in the reporting period. The team also has electricity used by a third-party warehouse that stores the organisation’s goods.Should these amounts be brought into the disclosure, and what supporting details need to sit alongside them?

Model answer. Yes, if the energy use happens beyond the organisation’s own sites but is part of the activity being reported, it belongs in the disclosure. Alongside the figures, explain the approach used to build the estimate or calculation, and identify where the conversion factors came from.

Why this matters. Include off-site energy use that is relevant to the reporting boundary, and pair the numbers with the method and factor source used to derive them.

A preparer has two ways to estimate courier fuel use: one based on mileage and vehicle type, and another based on supplier invoices for a sample of routes. The team chooses the mileage method because it covers all routes, but the sample invoice method gives slightly different results.What should be documented so a reviewer can understand how the figure was produced?

Model answer. Record the calculation approach chosen, the assumptions behind it, and any tool or model used to turn activity data into energy use. If more than one approach was considered, keep the rationale for the selected one clear, and state the source of the conversion factors applied.

Why this matters. The disclosure is not just a number; it needs enough method detail for someone else to follow the calculation path.

An energy analyst uses a spreadsheet with built-in conversion factors copied from a public database last updated two years ago. The analyst can see the numbers work, but the file does not note where the factors came from.Is the disclosure complete enough for sign-off?

Model answer. No. The figure may be usable, but the supporting information is incomplete because the origin of the conversion factors is not identified. The preparer should add the source of those factors and keep the calculation method and assumptions documented as well.

Why this matters. A valid estimate still needs traceable factor sources, not just a working spreadsheet.

A company reports fuel used by leased delivery vans operated by a contractor, but excludes electricity used by a data-processing service provider because the provider bills it as part of a service fee. The team is unsure whether to mention the calculation basis for the included fuel only.What should be covered in the narrative supporting the disclosure?

Model answer. The narrative should cover the off-site energy use that is included, and it should also explain the standards, assumptions, and calculation tools used for that figure. If conversion factors were applied, their source should be stated too; the fact that another off-site energy item was excluded does not remove the need to explain the basis for what is included.
