Carbon footprint for supplier SMEs
Your customer gave you two weeks.
You will need two hours.
Your customer’s carbon questionnaire has arrived, and you have neither an ESG department nor a consulting budget. Drop in your accounting file: Oakbon calculates your emissions and hands you back the report to send on, today.
The file stays with youIt is never sent. The calculation runs in your browser.
We see nothing of your accountsNot your entries, not your amounts, not your suppliers’ names.
Nothing to purge, nothing was ever transmittedYour entries disappear when you close the tab. Your footprint stays in your workspace.
You are
We do not all arrive here for the same reason.
The method and the emission factors are the same for everyone. The reason is not.
A customer is asking you for carbon data
A short deadline, no ESG department, and a place on a supplier list to keep.
Answer my customerYou run several companies
You chase your subsidiaries, you receive spreadsheets, you consolidate by hand.
Consolidate my groupYou produce your clients’ FEC files
You already hold the data. What you lacked was the engagement that goes with it.
Open the carbon engagementYou are an ESG consulting firm or an independent consultant
You redo the same work by hand for every client, and the engagement stops at the report.
Make my engagements repeatableWhy it takes so long
What makes a carbon footprint expensive is collecting the data.
Weeks spent gathering invoices, meter readings, consumption figures and mileage. That is where the budget of a carbon footprint goes, and that is where most projects stop.
The request lands without warning
A questionnaire arrives from your customer, with a short deadline and a vocabulary that is not yours. You have neither figures at hand nor anyone whose job this is.
The quotes are out of all proportion
A carbon footprint for an SME costs between 1,000 and 10,000 € excl. VAT in consulting1. That figure is defensible for a full advisory engagement. It is absurd for answering an annual request.
The driver is commercial before it is regulatory
Your customer has to report the emissions of its value chain, so it passes the request on to you. Banks look at these criteria when they assess a loan. Tenders ask for them.
Three steps
You drop in a file. The rest fits into a few questions.
No installation, no configuration, no training.
Drag and drop your accounting file
Accepted formats: FEC (.txt), .csv, .xlsx
Formats detected automatically
No configuration, no column mapping: the format is recognised as the file is read.
Drop in your file
The one your accountant hands you every year. Oakbon recognises Pennylane and Sage exports and the FEC on its own, and knows what each column means. Nothing to re-enter.
Answer the questionnaire
Plain-language questions about your energy, your travel, your deliveries, your waste and the heating of your premises. When you have a measured figure, kWh on an invoice or kilometres driven, Oakbon uses it rather than the amount in euros, and your figure is more accurate.
Download and send
The report is generated and downloaded. You send it on to your customer straight away.
The black oak stores carbon for centuries. We measure it in two hours.
The following year
A footprint that ends up in a drawer has served no one.
Your customer will be back next year, with the same request and one more question: what have you done since?
You track your reductions
Your targets are set out under article L229-25 of the French environment code, and your trajectory is compared against a 1.5 °C pathway.
You see your obligations coming
Oakbon places your company against the BEGES, CSRD, CBAM and VSME thresholds. The regulatory footprint applies above 500 employees, and above 250 in the French overseas regions and departments.
You compare one year with the next
Each new financial year sits alongside the previous one, with the same method and a base year managed under the GHG Protocol.
You survey your employees without wearing them out
An anonymous page, opened through a single-use link, replaces your commuting estimates with their own answers.
You consolidate your companies
Each company produces its own footprint, and Oakbon generates the consolidated footprint and a separate group report.
Commuting survey
An anonymous public page, reached by a link, that you send to your employees. The answers feed straight into category 7.

Methodology aligned with the GHG Protocol Corporate Standard and Corporate Value Chain Standard, and with the ESRS E1 disclosure requirements
Your deliverable
A document you send on exactly as it is.
At the end you have a PDF file to send to your customer, and exports for those who ask for something else. You have nothing to lay out.
- The report. Cover, supplier sheet, breakdown of your emissions, main contributors, indicators, methodology note, appendices and attestation.
- The exports. One for BEGES, CDP and EcoVadis. Another for the VSME standard. Your counterparties do not all ask for the same format, and you have them all.
- The action plan. Your emission categories ranked by weight, with quantified reduction actions. You know where to start before you leave the meeting.
Reconstruction of the report’s actual cover. The figures are those of the Dupont & Fils demonstration dataset, a fictitious company. The report is aligned with the GHG Protocol. It does not constitute an ISO 14064-3 certification and does not replace verification by an independent third party.
Why now
Your customer is asking for your emissions. Not the law.
Most SMEs are under no obligation to produce a carbon footprint. If your figures are being asked for, it is because your customer has to account for its whole supply chain. Not answering means leaving the place to a supplier who did.

2 hours
The time it takes you, between dropping in your accounting file and a report ready to send to your customer.
0 files sent
Your accounting stays on your own machine. The calculation runs in your browser, and we receive only totals.
And if you cross the threshold, you are already prepared. Above 500 employees the footprint becomes mandatory, is updated every four years and comes with a transition plan to publish. Oakbon produces both, without your having to start anything over.
Article L229-25 of the French environment code. The threshold drops to 250 employees in the French overseas departments and regions.
Frequently asked questions
What we are asked most often.
What is Scope 3 for a supplier SME?
Scope 3 covers the indirect emissions of your value chain: purchased goods and services, capital goods, upstream energy, upstream transport, waste, business travel, commuting and leased assets. It is very generally the largest share of the footprint of an industrial SME, and it is the figure your customer is asking you for.
How is a carbon footprint calculated from accounting data?
Every accounting entry is attached to its account in the French general chart of accounts, then to a GHG Protocol category, then to an emission factor from the Base Empreinte® ADEME. Oakbon works in two passes: a deterministic mapping by PCG account, then refinement from the keywords of the entry label. When a physical figure is available (kWh, litres, kilometres), the physical factor always wins over the monetary ratio.
Which files can Oakbon read?
The FEC (.txt) first, the Pennylane and Sage exports, and any CSV or Excel export whose headers are French. This is a file import: you drop in an export, Oakbon detects its format and reads it, with no column configuration.
Is a carbon footprint mandatory for an SME?
Under French law, the emissions reporting obligation (BEGES) applies above 500 employees, under article L229-25 of the environment code. Most SMEs are therefore not subject to it. The request they receive comes from their customers, not from the legislator, but it is just as binding in practice.
Can the report be put before an auditor?
The report is aligned with the GHG Protocol and sets out its methodology, its assumptions and its uncertainty range. It does not constitute an ISO 14064-3 certification and does not replace verification by an independent third party (OTI). That statement appears explicitly in the document you receive.
What happens to my accounting data?
Your accounting file never leaves your browser. The calculation runs on your own machine, and we receive only totals by category. We see neither your accounting entries, nor your amounts, nor your suppliers. What we store is encrypted with AES-256-GCM using a key derived per client, hosted by OVH in France, and nothing leaves the European Union.
