Voluntary approach
Corporate carbon footprint:
why calculate it even without a client request.
Most companies only calculate their carbon footprint when a client, an investor, or a regulation forces them to. Here’s why doing it voluntarily, before being required to, becomes a real advantage.

Haven’t received a carbon questionnaire from a client, a CSRD obligation, or any particular pressure? A corporate carbon footprint is still worth doing. More and more companies are getting ahead of it rather than waiting to be forced, gaining a concrete advantage before it becomes an obligation or a condition for accessing a market.
Six reasons to calculate your carbon footprint without being required to
The carbon footprint is no longer reserved for companies under regulatory obligation. Here are the most common reasons that drive a company to do it on its own initiative.
- Responding to tenders before you’re asked to : More and more public and private tenders include a carbon criterion, even below CSRD thresholds. Already having a footprint ready is a direct competitive advantage over competitors caught off guard.
- Reassuring banks and investors : ESG criteria are weighing more and more heavily in financing decisions, even for SMEs. A documented carbon footprint makes discussions easier with a banker or investor who now systematically asks the question.
- Anticipating the gradual expansion of regulation : CSRD thresholds were raised by the Omnibus package in December 2025, but the underlying trend remains toward broader carbon reporting. Starting early avoids having to discover everything in a rush the day the obligation arrives.
- Identifying energy savings : A high-emission item is almost always also a high-cost item (energy, fuel, travel). The carbon footprint often reveals cost-reduction opportunities that had never been quantified before.
- Standing out commercially : In sectors where price competition is fierce, a well-managed, clearly communicated carbon footprint becomes a sales argument, particularly with clients who are themselves engaged in a CSR approach.
- Preparing for a fundraise or a sale : Due diligence processes increasingly include an environmental component. A company preparing to raise funds or be acquired benefits from documenting its carbon footprint upfront rather than discovering it mid-negotiation.
This guide is for any company that wants to calculate its carbon footprint on its own initiative, whether it’s a supplier, a service provider, a retailer, or an independent industrial company. The method is the same as the one used to respond to a client request — only the motivation changes.
What a first carbon footprint reveals
Most companies discover that the breakdown of their emissions doesn’t match their initial intuition.
- Scope 3 almost always dominates. Purchases, transport, travel: between 70 and 90 % of total emissions for an industrial or commercial company, well ahead of direct emissions (Scope 1) or electricity (Scope 2).
- One or two items concentrate most of the volume. An energy-intensive raw materials supplier, a vehicle fleet, or a transport line item can alone account for half of the footprint.
- Orders of magnitude vary significantly by sector. A service company with few physical assets will have a very different footprint from an industrial or logistics company.
Where to start
A first corporate carbon footprint requires no consultant, no sensors, and no specialized tools. Your accounting data is enough for a first credible result.
- Gather a year of accounting data: an export from your software (FEC, Pennylane, Sage) or a CSV/Excel file of your purchases and expenses.
- Apply the emission factors from the ADEME Base Carbone, the official French reference database, to each spending category.
- Structure the result by Scope 1, 2, and 3 according to the GHG Protocol, the international standard, so the report can be used by a client, a bank, or an investor who later requests it.
