Ambu automated dataflows for Scope 3 carbon accounting, enabling quarterly GHG calculations with audit-ready transparency.
Ambu is a Danish MedTech company and the world leader in single-use endoscopes. With around 5,000 employees across four continents, its endoscopy, anaesthesia and patient-monitoring devices are relied on by millions of patients worldwide.

Besides being a pioneer within the field of medical equipment, Ambu is deeply committed to measuring and reducing its emissions and is part of the Science Based Targets initiative.
As a large, complex, multinational company, Ambu’s CO₂ data sits in different systems and arrives in huge volumes, and an annual GHG inventory covering Scope 1, 2 and 3 is a major undertaking.
In preparation for integrating new carbon accounting software, Ambu partnered with Viegand Maagøe to automate dataflows and workflows and perform calculations.
4 aspects were critical when setting up the data processing for the carbon calculations together with Ambu:
As a result of the project, Ambu has the set-up and tool in place to efficiently carry out quarterly emission calculations with the needed transparency and granularity. The tool today is fully embedded and operated by Ambu’s data and sustainability experts.
“Viegand Maagøe was key in establishing the recalculation of our GHG-inventories with our new system and software. What really made the partnership a success is that Viegand Maagøe, with Nikolaj Parbo and Morten Rolsted, combined expertise across advanced automation, data analytics, reporting frameworks and sustainability strategy.
The outcome was a user-friendly tool that enabled us to recalculate and restate five years of Scope 3 emissions in a single run, reducing a process that previously took weeks to just a few days while maintaining full transparency and audit-ready detail and ultimately supporting a clean audit outcome with no inquires or remarks.
We had a very close and intense collaboration during the project, and Viegand Maagøe always delivered in a timely manner. As a large company with ambitious goals on the climate agenda, we seek to only consult with ‘top of the class consultants’ when we use external experts.
This project is an example of why Viegand Maagøe is our trusted go-to partner in our sustainability endeavours.”
