Calculate your company's carbon footprint

A clear estimate of your annual emissions (scopes 1, 2 and 3), based on official ADEME and EPA factors. In minutes, no spreadsheet.

How it works?

Step 1

Enter your consumption (energy, travel, meals, purchases, waste).

Step 2

Choose your referential (ADEME for France, EPA for the United States).

Step 3

Get your footprint in tonnes of CO2e, broken down by item and by scope (GHG Protocol).

Step 4

Take action with support on your priority items.

Why measure your footprint now?

An expectation from your clients

Clients, broadcasters and advertisers ask for hard numbers. A credible assessment becomes a commercial advantage.

A management lever

Identifying your largest emitting items means knowing where to act first to reduce, and how much you can save.

A spreading obligation

The CSRD extends extra-financial reporting to more and more companies. Knowing your emissions is no longer optional.

Frequently asked questions

Is this calculator ADEME-compliant?
It uses the official emission factors from ADEME's Base Carbone and Base Empreinte, as well as those of the US EPA. There is no certification for a calculator: reliability comes from using official factors, with their version, and a transparent method. The detail of the factors is available in the tool.
What is the difference between scopes 1, 2 and 3?
Scope 1 covers your direct emissions, such as gas combustion or fuel for your vehicles. Scope 2 corresponds to the energy you purchase, mainly electricity. Scope 3 covers indirect emissions such as travel, purchases and waste, often the largest share.
Why choose between ADEME and EPA?
Emission factors vary by country. The French electricity mix, for example, is very different from the US mix. Choose ADEME for activity in France and EPA for the United States, to get an estimate consistent with your context.
Is my data stored?
No. The calculation runs directly in your browser. No entered data is stored or transmitted.
Is this result enough for my CSRD reporting?
No. It is an awareness estimate, not a regulatory or certified carbon assessment. For an accurate, auditable assessment, GreenPro and dedicated support take over.
How can I reduce my footprint next?
Start with your largest emitting item, highlighted by the calculator. GreenPro then helps you track your emissions over time and build a quantified reduction plan.

You have your estimate. GreenPro gives you the precise assessment.
