THE CHALLENGE
Does this sound familiar?
Your customers need your emissions data for their own Scope 3, and your bank asks for it at your next financing round. And every footprint costs weeks of manual work that is missing when it comes to cutting emissions.
Searching huge databases for factors
For every item you search for the right emission factor. For the right year, the right country and the right unit.
No trail to the source
Factors and assumptions sit in separate files. Next year nobody knows how a number came about. And the footprint is no longer comparable.
THE SOLUTION
Every number evidenced, every year comparable
Your data comes from invoices and lists instead of retyping. Factors, sources and assumptions stay attached to every number, so your footprint can be audited and compared year on year.

FAQ
Frequently asked questions about the carbon footprint
What is a carbon footprint?
A corporate carbon footprint records a company’s greenhouse gas emissions for one year. It is divided into Scope 1 (direct emissions, e.g. your own fleet), Scope 2 (purchased energy) and Scope 3 (upstream and downstream value chain). The most widely used standard is the GHG Protocol. Code Gaia calculates Scopes 1 to 3 under the GHG Protocol, with a method certified by TÜV Rheinland.
Is a carbon footprint mandatory for mid-sized companies?
For most mid-sized companies there is no direct obligation. From financial year 2027, companies with more than 1,000 employees and more than €450m turnover report under the ESRS. For this they need their suppliers’ emissions data for their own Scope 3. Banks are also increasingly asking for emissions data when it comes to financing.
How does Code Gaia capture Scope 3 emissions?
Code Gaia captures Scope 3 in two ways: spend-based, with Kurt AI mapping booking lists to emission sectors (Scope 3.1), and activity-based via invoices, travel data or Excel uploads. The software picks the right emission factor by time and location.
How does AI help with the carbon footprint?
Kurt AI, the AI in Code Gaia, reads invoices for electricity, fuel, transport, travel, accommodation and waste and creates activities from them. For booking lists and Excel files, Kurt AI suggests emission sectors, activities and factors. You review and approve every suggestion.
How traceable is the calculation?
TÜV Rheinland has certified Code Gaia’s calculation method for Scopes 1 to 3 against the GHG Protocol (Corporate Standard and Scope 3 Standard). In the software every number stays traceable to its source, and the footprint is comparable year on year.
