To prepare this disclosure
Disclosure focus

This disclosure asks an organisation to explain how much energy it uses and what that energy is made up of. In practice, the report should show the organisation’s energy use in a way that is clear enough to understand the main sources and the balance between different energy types, rather than just giving a headline total. The emphasis is on describing the organisation’s actual energy profile in a structured way.

The practical focus is usually on coverage across the organisation’s activities, not only a few flagship sites or best-performing locations. A useful report should make clear whether the figures cover all operations, selected entities, or specific sites, and should help readers see where the main energy demand sits and how the mix varies across the business.

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

Before you start

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

Preparation

Key datapoints to prepare

Datapoint What to capture Evidence hint Owner
Total electricity use Capture the full amount of electricity used in the reporting period, expressed in MWh, on the same basis used for the rest of the energy figures. Utility invoices, meter exports, energy management system totals, and the period-end consolidation file. Energy / Sustainability / Finance
Fossil electricity use Capture the MWh of electricity use that comes from fossil-based sources for the reporting period, using the same boundary and period as the total energy figure. Supplier mix statements, contractual energy records, and the energy roll-up used for reporting. Energy / Sustainability / Procurement

How to prepare it

1Set the reporting boundary first. Decide which parts of the business, sites, and activities are included in the energy figures, then keep that scope consistent across every item in this disclosure.
2Define the energy categories you will use before you start counting. Separate the totals into the required source groups, including fossil, nuclear, and renewable energy, and make sure any production figures are split between renewable and non-renewable output.
3Gather the underlying records that support each figure. Use meter data, invoices, production logs, or other internal evidence that lets you trace the numbers back to a reliable source for the reporting period.
4Build the reported values from the evidence. Enter the total energy amount, then populate the relevant breakdowns for each source type and production category, keeping the figures internally consistent.
5Record any exclusions, estimates, or changes in method. If a source, site, or data set is left out, or if the calculation approach differs from prior periods, note what changed and why so the reader can follow the trail.
6Check the final submission against the official source before filing. Confirm that every required item is covered, the labels match the disclosure, and the numbers or narrative align with the source records and the current reporting rules.
Request the data

Request energy use and fuel mix data from Operations

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

What energy did we use in the reporting period, and how was that energy split across fuel and generation types?

Use your own site, utility and fuel names first, then map them to the reporting categories in the pack. Keep the ask in the language your team already uses for meters, invoices, generators, purchased power and on-site generation, rather than using framework terms in the request itself.

Weak request

Please provide the ESRS E1:E1-7 energy consumption and mix data, including total MWh and the split by fossil, nuclear and renewable, plus coal, oil, gas, other fossil, renewable production and non-renewable production.

Why it fails: This uses framework language that many operational teams will not recognise, so it is harder to action quickly. It also does not tell the owner which systems, sites, labels or assumptions to use, or what supporting records to return.

Better request

Please send the energy and fuel figures for [reporting period] for [sites/assets], using the labels your team already uses for meters, invoices, fuels and on-site generation. Include the total energy used, the split by fuel or generation type, the source extract or records, any conversion factors, and any gaps or estimates. Please adapt this to your organisation’s own terms and check the source material before sign-off.

Formal email template

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 basis used to classify each energy figure, including how the reporter has grouped sources into fossil, nuclear and renewable categories and how production figures are defined for the period covered.

Context note

Explain what the totals and splits show about the organisation’s energy profile, including the relative weight of fossil, nuclear and renewable energy and how production is distributed between renewable and non-renewable output.

Fluctuation statement

If any figure moves materially, describe the main operational or sourcing reasons behind the change and note whether it reflects a shift in the energy mix, production levels or both.

Assurance readiness

For each claim, check the evidence

ClaimRiskEvidence to check
We prepared the coverage figure using a cautious split between renewable and non-renewable supply where the source mix was not directly clear.An assurer may test whether the split method is genuinely cautious, consistently applied, and not used to overstate the renewable share.Method note showing the split logic; source data and assumptions; working papers showing how ambiguous cases were treated; review sign-off on the final allocation.
We kept any fuel used as an input to make other products separate from the energy totals we reported.An assurer may probe whether excluded feedstock volumes were identified correctly and kept out of the energy totals without omission or double counting.Process notes on what was treated as feedstock; inventory or production records; reconciliation between operational data and reported totals; evidence of review of exclusions.
Where we used a market-based view for the renewable share, we held contracts that clearly show what environmental attribute we bought.An assurer may check whether the contractual evidence actually supports the market-based classification and whether the attribute claimed is specific and unambiguous.Contracts, certificates or other purchase records; terms showing the environmental attribute transferred; supplier correspondence; internal checklist confirming the attribute matched the reported classification.
We presented renewable output and non-renewable output as separate figures in the same unit.An assurer may test whether the two streams were separated correctly, converted on a consistent basis, and reconciled to source records.Production logs; conversion calculations; reconciliation to meter or plant records; review evidence confirming the separate presentation.
We recorded how the renewable share was worked out, and we identified whether the approach followed a market-based or a location-based basis.An assurer may probe whether the chosen basis was applied consistently and whether the underlying data support that basis.Calculation methodology; basis selection memo; source data used for the calculation; evidence of management review and approval.
We built the total energy figure from operational records and then split it by source type for reporting.An assurer may check whether the total is complete, whether the source split is accurate, and whether the reported unit and boundaries are consistent.Energy ledger or consolidation workbook; utility and fuel records; boundary and scope notes; reconciliation to the final reported total; sign-off evidence.

Evidence pack to prepare

Common reporting gaps

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.
Common gaps

Mistakes to avoid when collecting the data

Wrong owner asked
Chasing the sustainability team for meter data instead of the facilities, utilities, or procurement owner usually means the figures come from someone who does not hold the original records.
Framework terms used too early
Requesting data in disclosure language rather than the organisation’s own labels can leave teams unsure whether you mean site electricity, fuel invoices, or another internal energy bucket.
Boundary not fixed
If you do not state which sites, entities, or operations are in scope, different teams may send numbers for different parts of the business and the totals will not line up.
+ Show 6 more

Where judgement is often needed

Set the group boundary for bought or sold businesses
Decide whether to include energy from businesses added or removed during the year on a closing, opening, or time-apportioned basis, and explain the cut-off used so readers can see how the total was built.
Align local fuel labels to one group-wide mapping
Where country teams use different fuel names or categories, map them to one consistent internal classification for the report and disclose the mapping rules used.
Handle mixed-use energy records consistently
For sites or meters that cover both in-scope and out-of-scope activity, state the allocation method used and explain how shared consumption was split or excluded.

Illustrative examples

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

Illustrative (synthetic) example — Manufacturing

We report our purchased and self-generated energy for the year, split between low-carbon and fossil-based sources, and we also show how our own output is divided between renewable and non-renewable forms. - Total energy used: 120,000 MWh, of which 78,000 MWh came from fossil-based sources, 12,000 MWh from nuclear, and 30,000 MWh from renewable sources. - Fossil-based use is broken down as 18,000 MWh coal, 22,000 MWh oil, 30,000 MWh gas, and 8,000 MWh other fossil fuels; our own production was 14,000 MWh renewable and 6,000 MWh non-renewable.

Synthetic example for practitioner training only; figures are internally consistent and illustrative, not reported facts.

Illustrative (synthetic) example — Transport and logistics

Our year-end energy picture separates total consumption from the main source types, and it also distinguishes the electricity and heat we produced ourselves by whether they were renewable or not. - We used 84,000 MWh in total: 42,000 MWh fossil-based, 6,000 MWh nuclear, and 36,000 MWh renewable. - The fossil-based portion comprises 10,000 MWh coal, 12,000 MWh oil, 15,000 MWh gas, and 5,000 MWh other fossil fuels; our own output was 9,000 MWh renewable and 3,000 MWh non-renewable.

How companies report E1-7 in practice

Real reports where this topic is disclosed. These are report practice, not exact disclosure templates to copy.

Danone S.A.
Food Production — Animal Source · France · 2025
Open report →
Danone S.A.'s Universal Registration Document 2025 provides numeric data on renewable energy consumption, reporting total renewable energy use of 19,273 MWh, 23,412 MWh, and 25,474 MWh on page 362, with similar figures noted on page 229. The report also details fossil energy consumption and indicates that renewable electricity purchases from Energy Attribute Certificates (EAC) range between 80 to 90% (p.362). However, there is no quotable narrative explanation or contextual information about renewable energy in the report.
Banco de Sabadell, S.A.
Banks / Diverse Financials / Insurance · Spain · 2024
Open report →
Banco de Sabadell’s 2024 Consolidated Non-Financial Disclosures report provides numeric data on energy consumption, showing zero consumption of purchased or acquired electricity, heat, steam, and cooling from renewable sources (p.110). The report also indicates no consumption from nuclear sources in total energy consumption (p.110, p.111). However, there is no narrative explanation or further qualitative detail about renewable energy use or related sustainability initiatives, as no quotable narrative evidence was found in the report.
ÖBB Holding / Rail Cargo Group
Ground Transportation — Railroads · Austria · 2024
Open report →
ÖBB Holding / Rail Cargo Group’s 2024 Annual Report provides detailed numeric data on energy consumption, reporting total energy consumption figures and the share from renewable sources, with renewable energy consumption around 1,965,000 MWh and fossil sources comprising roughly 34-35% of total energy use (p.128). The report also specifies that nuclear energy is not part of their energy mix, with a 0% share noted (p.128), and includes energy generation from renewables at approximately 1,291,742 MWh for 2024 (p.128). However, the report lacks narrative explanations or qualitative disclosures related to energy consumption or sustainability strategies, with no quotable narrative evidence found throughout.

Scenarios to work through

A preparer has the year-end energy ledger for a manufacturing site. The ledger shows 12,400 MWh used in total, split between grid electricity, on-site gas boilers, and a small amount of purchased steam, but the team has not yet grouped the figures into fuel categories for the disclosure.

QHow should the preparer decide whether the total and the energy-source split are ready to report, and what needs checking before sign-off?
Reveal model answer →

A group treasury team has bought electricity from a supplier that markets a “green” tariff. The contract file shows certificates, but the operations team is unsure whether the purchased power should be treated as renewable in the energy mix table or left in a separate note.

QWhat judgement should the preparer make about classifying that electricity for the energy mix disclosure?
Reveal model answer →

A utility subsidiary generates power for its own use and also exports some electricity to the grid. For the reporting year, it produced 8,000 MWh from solar panels and 2,000 MWh from gas turbines, while 1,500 MWh was used internally and the rest was sold externally.

QHow should the preparer think about the production figures when completing the energy mix disclosure?
Reveal model answer →

A finance team is preparing the draft disclosure for a diversified group. One business unit uses coal and gas, another uses only purchased electricity, and a third has a small nuclear supply contract; the team is unsure whether to present only the dominant source or every source that appears in the records.

QWhat is the right approach to deciding which energy sources to include in the mix disclosure?
