International API

Published 15 Feb 2024

BeWo, a Danish company that enables organisations to track their environmental footprint, is one of the most recent users of BASTA’s API. And the third international API user!

4 years ago, BeWo was founded by Mikkel Bering Alstrup, Jacob Bruun and Allan Tharuman with the mission to provide accurate environmental data. BeWo helps small and medium sized companies to calculate carbon emissions from their purchases, to be used in reports or as a base for reduction strategies. The calculation is performed by BeWo’s AI engine in all three scopes, based on the GHG protocol and seamlessly integrating with a company's financial or ERP system to accurately extract necessary data.


Jacob Bruun, co-founder and CTO, explained that the industry for trustworthy environmental data is growing:
-    The increased demands for sustainability reports and the taxonomy regulations from the EU mean that all businesses will have to track their emissions. One of the fastest growing sectors is construction and real estate, where information from BASTA’s API will be used. 

Our service picks up information from purchased products from the client’s finance or ERP system and imports it into our database, where the carbon emissions are calculated. BASTA’s API helps us identify the products and their content.


BeWo became of the around 20 organisations who used BASTA’s free API. For BeWo and Jacob, the reason behind choosing BASTA was precisely that it was free and user friendly.  
-    We saw that BASTA had a free and open API, where it would be easy for us to get data. Other options are built in proprietary software and with a cost attached, which wasn’t a good option in comparison. Using the BASTA API we can access a high amount of EPD information, which is the most accurate environmental data available, says Jacob Bruun.


The API is one of the foundations of BASTA, together with the logbook service and the open database. It can be used by distributors to display product grades, contractors to achieve certain environmental certifications and for any organisation with internal requirements regarding the content of products.
