Many companies with 50 to 500 employees are asking whether they become legally required to prepare a French BEGES in 2026. The answer must be precise: as of 3 May 2026, there is no general BEGES obligation for every private company with 50 to 500 employees in metropolitan France. The official threshold applies to private legal entities employing more than 500 people in metropolitan France, and more than 250 people in French overseas regions and departments. However, SMEs in the 50-500 range are increasingly asked for carbon data by customers, banks, investors, tenders and large groups preparing CSRD reporting.
This article complements our French content on carbon footprint and profitability, CSRD preparation, VSME 2026, ESG reporting and double materiality. For support, see ESG and CSRD reporting, statutory audit, outsourced CFO, CSR sector expertise and Power BI.
Executive summary#
The French regulatory GHG inventory is governed by Article L.229-25 of the Environmental Code. The Ministry for Ecological Transition recalls the thresholds: private legal entities with more than 500 employees in metropolitan France, private entities with more than 250 employees overseas, state services, certain local authorities and other public bodies.
| Company | Mandatory BEGES in 2026? |
|---|---|
| Private metropolitan company with 50-500 employees | No general BEGES obligation based only on this headcount |
| Private metropolitan company with more than 500 employees | Yes, under the regulatory framework |
| Private overseas company with more than 250 employees | Yes, under the regulatory framework |
| Supplier of a CSRD group | Not always legally mandatory, but often commercially requested |
| SME bidding for ESG-sensitive contracts | Voluntary BEGES can be strategic |
Freshness note: updated on 3 May 2026. Any future extension of scope should be checked against official legal texts.
What a BEGES covers#
The BEGES measures an organisation's greenhouse-gas emissions and includes a transition plan. Since the 1 July 2022 decree, entities subject to the obligation must include significant indirect emissions, increasing the importance of Scope 3.
| Area | Example data |
|---|---|
| Energy | Electricity, gas, fuels |
| Travel | Vehicles, mileage, business trips, commuting |
| Purchases | Materials, subcontracting, services, packaging |
| Fixed assets | Equipment, IT, vehicles, fit-outs |
| Waste | Volumes, treatment and recycling |
| Freight | Upstream transport, downstream transport and deliveries |
Why 50-500 employee companies should still prepare#
No general legal obligation does not mean no business issue. Large customers subject to CSRD need supplier data for their indirect emissions. Banks are gradually integrating climate trajectories into financing decisions. Tenders ask for evidence. Investors review physical risks, energy, transport and supplier dependency.
Our accountant's view: for an SME, a voluntary BEGES is useful when it connects emissions to margin. Transport, energy, purchases and waste are not only emissions. They are also costs and operational risks.
The underestimated risk: a decorative carbon report#
A BEGES or carbon footprint prepared only to tick a box may become unusable: undocumented emission factors, incomplete purchasing data, fleet omissions, unstable perimeter, no action plan. The risk is commercial as well as technical because a customer or bank may ask for evidence.
Preparation checklist#
- define the entity and perimeter;
- choose a reference year;
- collect energy, fuel, purchasing, travel, fixed-asset and waste data;
- identify significant emission categories;
- document assumptions and emission factors;
- build a quantified reduction plan;
- publish or share results depending on legal or commercial need;
- update strategic indicators annually.
What management must decide#
| Decision | Why it matters |
|---|---|
| Regulatory or voluntary BEGES | Avoid confusing legal duty with commercial opportunity |
| Scope 3 detail level | Focus effort on material categories |
| Internal data owner | Secure data across finance, purchasing, HR and operations |
| Reporting format | ADEME platform, customer report, VSME or banking file |
| Action plan | Turn diagnosis into cost and risk reduction |
2026 watch points#
- Do not claim a general 50-employee BEGES obligation that does not exist.
- Check the overseas threshold if the company employs staff in French overseas territories.
- Link BEGES, VSME and CSRD data where they overlap.
- Keep evidence: energy bills, mileage, purchases and vehicle fleet data.
- Avoid unfunded or untracked reduction promises.
Frequently asked questions
Does a French SME with 80 employees have to prepare a BEGES?+
Not solely because of its headcount in metropolitan France. It may still be requested by a customer, bank, investor or tender.
Is the 500-employee threshold assessed by establishment?+
The framework targets legal entities. Groups and multi-site organisations should review their legal and operating perimeter before concluding.
Is Scope 3 mandatory?+
For entities subject to the obligation, significant indirect emissions must be included since the 2022 regulatory change. For a voluntary SME, Scope 3 is often the most useful part because it covers purchases, transport and use patterns.
Are BEGES and carbon footprint the same thing?+
They are related but not always identical. BEGES is the French regulatory framework. Carbon footprint is often used more broadly for carbon-management exercises.
How can the project stay proportionate?+
Start with material categories and available data: energy, fleet, purchases, freight and waste. Then connect the findings to budget decisions.
