Sami vs Excel: switch to a carbon platform without starting from scratch
Import your files as they are, rely on 300,000 emission factors and manage your carbon footprint with your teams and our climate experts.
Is your carbon footprint still in a spreadsheet?
Excel works for a first calculation. Difficulties start when the scope widens and audits get closer.
Errors that are hard to spot
Every emission factor is looked up and entered by hand. One wrong cell reference is enough to skew the result.
Scattered data
Energy, purchasing, travel: each category lives in a different tab or file, with no consolidated view.
Not enough traceability for audits
For CSRD or SECR reporting, a CDP submission or third-party verification, you need to justify every figure. Without that, your public commitments rest on fragile ground.
A file that is hard to scale
More suppliers, entities and Scope 3 categories: maintenance time grows every year.
Know-how held by one person
Every spreadsheet has its own tabs, macros and conventions. When its author is away, picking it up is difficult.
Teams working in silos
Purchasing, sites, finance: everyone keeps their own version. On a shared platform, everyone speaks the same language and saves time.
Your data has its own format. Sami adapts.
For each emission category, choose the collection mode that suits your data. Both can be combined in the same footprint.
Ready-to-use collection

What changes for your teams, from data collection to audit.
Configure once, save time every year
Your calculation rules are carried over from one year to the next, with no reprocessing.
Import your files as they are
Form or Excel export: map your columns to the expected format. Errors are flagged and can be fixed directly in the table.
Automate your calculations with allocation rules
A rule assigns the emission factor, category and GHG Protocol scope to every line that meets your conditions. One data point can carry several emissions, for example combustion and upstream for energy consumption.
Reuse your configuration the following year
Duplicate collectors, their fields and rules in a few clicks. Compare year on year to see which categories changed most.

Rely on up-to-date emission factors
Multi-criteria databases (ecoinvent, Base Empreinte…) and specialised ones (INIES, Agribalyse, NegaOctet…) are cleaned and structured by our experts into a single format. An alert tells you when a newer version of a factor exists, and you can add your own factors in full confidentiality.
Move to Sami in three steps
1. Import your Excel files
Map your columns to the expected format. Your history is preserved.
2. Get your data reviewed
Your Sami expert applies the right emission factors and flags gaps with best practice.
3. Manage your footprint
Dashboard, compliance-ready reports, platform training and unlimited users.
Go it alone or with our support
You stay in control
You configure your collectors and allocation rules directly in the platform, with no calculations to redo outside the application.
Our experts set it up for you
Your Sami expert configures the collectors around your data. You upload your exports as they are and can take over the following year.
Your questions answered
Can I import my existing Excel data?
+
Yes, as it is. You map your files’ columns to the expected format, and errors are flagged before import. Sami accepts spend data, activity data and pre-calculated emissions.
Will my figures change?
+
Probably, because Sami applies more detailed emission factors. Your expert explains the differences so you can present them confidently internally.
How long does it take to get started?
+
Importing an existing footprint takes one day. Full set-up (entity configuration, contributor training) takes a few weeks depending on your scope.
Do I need technical skills?
+
No. Sami is designed for teams in charge of climate strategy, and platform training is included.
I run a consultancy. Is Sami right for me?
+
Yes. With Sami Pro, consultancies manage their clients’ footprints on a single platform, using either the GHG Protocol or Bilan Carbone®.
